Implantation window: its importance and how to prepare for embryo transfer #IVFWEBINARS

Find out how to prepare for embryo transfer and learn how important the implantation window is for embryo implantation. Watch the video recording from our webinar with Dr. Roksolana Semchyshyn, Ph.D., M.D., from Intersono Clinic.

The webinar presentation covers all you need to know about:

  • the role of endometrium in the onset of pregnancy: the importance of its thickness, structure, presence or absence of inclusions, polyps;
  • what actually is the implantation window?
  • the importance of endometrial cell competence, ability to attach an embryo: immunological factors, HLA compatibility and thyroid effects;
  • preparing the endometrium for embryo transfer using medication, what you need to pay attention to and key aspects of endometrium monitoring during cryocycle.

Implantation window and its importance – Questions and Answers

Question:

Is cramping on day 5 for post transfer normal?

Answer:

As for me cramping it is not connected to the embryo transfer. If I am understanding what do you mean by cramping?

Question:

Let’s go back to the (first) question from Linda she has asked its cramping on day 5 post transfer normal? And, she added “Yes cramping after”, she means after embryo transfer.

Answer:

I can’t understand what is cramping.

Question:

She means “cramping similar to period cramps”. So, we had the question here, “cramping on day 5 post normal” so she means cramping similar to period cramps.

Answer:

Yes, sometimes, you mean the uterus cramping? Okay, normally you don’t feel the cramping of the uterus. But sometimes if you have very painful periods, this means that the uterus cramps. After an embryo transfer is not connected with the cramping of the uterus. The uterus, this is a muscle, and for a muscle this is the normal situation when it’s cramping. So, if you feel pain sometimes when we use progesterone, the progesterone can influence the intensity. So sometimes these painful feelings, these are not due to the uterus, but due to the intestines and due to the reaction of the progesterone.

Question:

My problem is that my endometrium doesn’t get thick enough I just had a biopsy done. Should a hysteroscopy be done as well?

Answer:

If the endometrium is not thick enough, hysteroscopy will not help us. Why? Because hysteroscopy is a diagnostic just to see what is going on inside, and not to correct the thickness. Hysteroscopy can show us polyps, can show us including into, inside the uterus, can show the endometrium, but not help make the endometrium thicker. What can we do? We have two options. First of all, we can choose the protocol without agonist so we can try not to suppress your body and to start with oestrogen. Also, nowadays we are use the medicine which can stimulate endometrium growth. This is growth factor which we put into the uterus and the endometrium starts to gro. We use those factors maybe a few days before the embryo transfer 2 or 3 days before. In Europe this is called Neupogen. This is a growth factor which we put inside the uterus. When we are inserting then we do ultrasound scan in 2 or 3 days and we can see that one millimetre or even 2 millimetres. We can see the growth of the endometrium.

Answer:

And also, once again, we can have a thin endometrium when we have an inflammatory process in the individual. So maybe the option is when you receive the results of the biopsy, just to understand what is going on inside the uterus. If they have an inflammatory process, we can just correct the inflammatory process inside the uterus and maybe we will get the normal thickness of endometrium.

Question:

Are there any food or drinks that will help to thicken the lining?

Answer:

No, sorry for that there is not any food or drinks that can help us to thicken our lining. We understand that in some foods are oestrogens but this is like a legend more than really help for us.

Question:

Could you explain if IVF attempts can create polyps?

Answer:

IVF attempt can’t create polyps, but if they have very small polyps inside the uterus during IVF procedures, we use hormones in a higher dosage then your body provides. So sometimes when we use IVF protocols with a stimulation, we can see that the polyps are growing so the polyps can grow during IVF procedures.

Question:

What is a polyp?

Answer:

This is changed cells of an individual when we have abnormal growth of endometrium cells. They are dividing incorrectly and, in that place, when we have the incorrect division of the cells, we have multiplication of those cells and those cells grow into polyps. Polyps are incorrect division of the cells

Question:

How about menopausal embryo transfer?

Answer:

So menopausal, this means that our body produces hormones in an incorrect way, but still our uterus is ready for implantation if we will provide the uterus with a normal level of hormone. So, if you have menopausal patients, we just work with them with long protocols and we prepare, at first for maybe three or four months, then with oestrogens and prepare the endometrium prepare the uterus for the normal cycling on the hormones and then we can start with IVF procedures with a long protocol and we can do the embryo transfer.

Question:

How soon after IVF procedure women may fly back home?

Answer:

After IVF procedures, we recommend, on the same day, stay at the clinic. After the embryo transfer, we recommend to stay one hour at the clinic and you can fly the next day. But sometimes patients fly the same evening.

Question:

How can I prepare for the transfer? Lifestyle, exercising, is there any way I can influence it?

Answer:

First of all, you need to rest. You need to have a good mood, because this is very important to have a good psychological condition and to be convinced that everything will be okay. About the lifestyle, I understand this is a good option for the lifestyle during the preparation for IVF attempt and that’s all. You need to take vitamins you need to be active and you need to have a normal weight because also if you have a higher weight this is not good for our IVF attempt.

Question:

Is the window of a patient measured from the first day of the cycle, or the first day of progesterone?

Answer:

I’ll measure the window of implantation from the first day of the progesterone.

Question:

On day 20 after embryo transfer it is it normal to have a light bleeding two days in a row?

Answer:

After embryo transfer you’ve the small discharges maybe a week after embryo transfer. Why? Because during the implantation when the embryo implants into the endometrium we can have some brownish discharges. If we have a good implantation, and we after 14 days, after the embryo transfer, we do the RCT test and we understand that we are pregnant. If we are pregnant the bleeding is not normal. When we have bleeding, this means that something is not good and at the embryonic sac is not correctly implanted into the uterus. So, in that case we recommend to have lighter regime of lifestyle. Don’t have intercourse, and to take some medicines just to prevent it from bleeding.

Question:

We are interested in the surrogate program. Will all the tests mentioned here be done on the surrogate mother? For example, ERA test?

Answer:

No, we don’t do ERA test for the surrogacy mother. Why? Because the surrogacy mother has already had babies. So, she doesn’t have infertility problems, and we understand that there is no problem in the receptivity of the endometrium. What we are doing for our surrogacy mothers is, we monitor the hormones, we monitor the immune system, we monitor her general health, but not ERA test.

Question:

Do you recommend clients stay in Ukraine for the complete cycle and to equate, if not, what are your recommendations, please?

Answer:

It depends on the patients. If we are talking about frozen embryo, when we have, for example, egg donation programs or we have embryo adoption. This means that the main process will be only during the embryo transfer and before the embryo transfer this is only preparation and ultrasound scanning. So, we can do it distantly. We are preparing the protocol, and you are doing in your country ultrasound scanning and just send it to our doctor. If we are talking about fresh stimulation, this means that you will be stimulated. We have also two options, if you have the opportunity to buy medicines in your country and to have ultrasound scanning in your country, you can do it in your country, and come here only for the egg collection or for the embryo transfer. If you don’t have the opportunity to buy the medicines in your country, then you need to be to be here. But you also have the option that we can help you with the medicines. We can prescribe it, and with our prescription you can go to the pharmacy and to have the medicines.

Question:

Do you know how long the window of implantation lasts from suggested time of your test?

Answer:

Up to 48 hours, if we are doing the ERA test. We do it, as usual, on the day 6 of progesterone, and we received 3 variants by the endometrium is receptive. This means that we can do the classical embryo transfer on day 6 of progestin. If we find that the endometrium is pre-receptive, this means that we need to wait one more day. Usually, they are waiting how many days to the embryo transfer, they recommend one or two. If this is post receptive endometrium, they also show the time, how many days you need to do the embryo transfer before that test.

Question:

If you are on a long protocol and after stopping OCP you get your period earlier or later than expected by the doctor in your protocol, what happens then? Where all your scans and flight are booked in advance?

Answer:

If we have a long protocol, and the period started earlier, this is not a problem. Because, when you are on a long protocol, your hormones are supressed, and we can start the stimulation later. So, the agonist, three shots, are present for 28 days in our body. So, this is enough time to have a delayed work (break in transmission.) This doesn’t make a big influence on our stimulation. If you have a delay of the periods, we plan the embryo transfer within 14 days of preparation. But we see that from 12 days this is enough for the endometrium to grow So we have 3 days 3, 4 days to just, to move in with our stimulation if they have a delay for 3 or 4 days, this is not a problem. If they have a delay for a week, then it can be a problem because we need to move our embryo transfer.

Question:

I have high NK cells and poor egg quality and I’m going to use egg donation how will this affect HLA antigens and the receptiveness of my endometrium?

Answer:

If you are going through egg donation programs, and you have high NK cells, we recommend the use of intravenous immunoglobulin. What is this? This is medicine that has an influence on the immune system. When immunoglobulin is in your blood, they just come in contact with NK cells, and NK cells start attacking immunoglobulin, and during this your pregnancy starts to implant and starts to grow. If we’re talking about immunoglobulin, then we have no influence on the antigens because we because we are using an immuno correcting therapy. And also, we have problems with actually antigens only in 2.3 percent of the patients. So, it’s a very rare problem, so the chances that our donor egg women, our donor and the husband will have the same actual antigens is very low.

Question:

What treatment do you suggest for high NK cells?

Answer:

We use intravenous immunoglobulin.

Question:

In your guaranteed program do you offer it till the heartbeat? How many weeks pregnancy? How many attempts?

Answer:

In our program will have three attempts. We offer it until the heartbeat. Also, this is to six weeks of pregnancy.

Question:

Will you be at the fertility show London in November?

Answer:

We will be in the conference in London in November as doctors but not as consultants.

Question:

What TSH levels required in order to for implantation to occur and also what TSH level is necessary for pregnancy to continue and be sustained?

Answer:

For us a suitable TSH level is less than 3. If they have a level of TSH higher than 3.5, there is an option for endocrinologist to lower the TSH level.

Question:

Do you wait until the blastocyst to transfer? Or do you transfer before, if so, day 5 or before?

Answer:

Earlier we would do to the embryo transfer on day 3. But nowadays mostly maybe in 98% of our transfer, this is day 5, blastocyst stage transfer. Why? Maybe a few years ago there was an idea that at that moment, this is the best option for the embryo, and if they have a poor-quality embryo, or we have very few embryos, then it’s better to have day 3 embryo transfer than to have the day 5 transfer. Nowadays, we understand that on day 3 our embryo is not in the uterus, it is still in uterus tube, and the situation in the uterus tube is quite different than in the uterus. So, it makes no sense to put the embryo on day 3 into the uterus, and to say that it’s a better condition for the embryo. So, we prefer to stay on the blastocyst stage embryo transfer. In this case we can understand that we have the good quality embryo. Then we receive the good quality embryo and we have a good chance for implantation. Especially in the case of the male’s factors and thus during when we have the problems with the sperm quality and the male factor start to affect the embryo on day 4. So, we can have a good quality embryo on day 3, and then have a bad quality embryo on day 5. So, our policy is just to wait, and to understand that we put a quality embryo inside the uterus.

Question:

Do you use progesterone injection or suppositories or both? What is your opinion about using Meprednisone without immunological testing?

Answer:

As for the first question we use progesterone injection and suppositories or use both. We use, in the morning, injections and in the evening, we use suppositories. Injections, we can have intramuscular or subcutaneous. Nowadays we have a very good medication, named Prolutex. This is progesterone, which we use subcutaneously. So, you don’t have painful feelings, as when we use intramuscular progesterone. About Meprednisone, we don’t use it without immunological testing.

Question:

I lose my pregnancy on the donor always at week 5 to 6. Is this stage related to endometrial receptivity?

Answer:

No, if you’re talking about the receptivity, this means that you have no implantation. When we have pregnancy loss at the terms of 5 or 6 weeks, in most cases this is either bad chromosomes, or either in immunology factors.

Question:

Do you do the endometrial biopsy to do the histochemical tests on the biopsy tissue? This test may show endometrial inflammation not recognized during the hysteroscopy. I have had this situation and the result was endometrial inflammation, with micro polypack endometrium. I was given Doxycycline antibiotic. It was two years ago today. The doctor in the clinic does not do these tests anymore. Has something changed? Or, was this not important for the implantation?

Answer:

We do the endometrial biopsy and we also do the histochemical tests for the bio type tissue. Just to see if we have inflammation inside. We also think that this is an important issue, especially if we have a thin endometrium, or we have a failed implantation before and we also use antibiotics when we perceive inflammatory process inside the uterus.

Question:

Does coffee affect implementation negatively?

Answer:

No, there is no evidence.

Question:

What do you do with immunological problems? Do you use tacrolimus or only intralipids?

Answer:

Yes, if you have immunological problems, we can use several options. First of all, we can use methylprednisolone this is a hormonal medicine. Also, we can use intralipids or we can use intravenous immunoglobulin. Intravenous immunoglobulin, is are the most expensive and methylprednisolone this is the cheapest one. So, intralipids is between them. But the most effective, this is intravenous immunoglobulin.

Question:

What test do you use to determine the implantation window is it ERA or ER-Map? Are these tests different? Which is better?

Answer:

In Ukraine we use electronic microscopy test. We search for pinopodes, those cells which are responsible for the implantation. We also receive the answers if the endometrium is receptive or not. When those pinopodes are present in the endometrium. When we do electronic microscopy of the endometrium. We do a biopsy, but we do three biopsies. On day 6, on day 8 and on day 10 of progesterone. So, it’s a little bit longer than ERA test. When we do ERA test, we also can do ERA tests in Ukraine, then we do only one biopsy on the basis of progesterone. We receive not pinopodes, we receive the information about the expression of the genes which are responsible for the implantation. The difference is between the information that we receive. In the ERAs we received information about the genes which are responsible for the implantation and in electronic microscopy we receive the cells which are responsible for the implantation.

Question:

Do you recommend transfer of embryo in the same cycle of stimulation? I mean if IVF was old age do you recommend to freeze the embryo and transfer next cycle?

Answer:

Nowadays the new trends in IVF field this is “freeze all” technique. Why? We really have better result with frozen embryo transfer then with fresh embryo transfer, but it depends also on the reason for infertility of the quality of the embryos, the quality of endometrium. If we have the same quality of good quality embryos, good quality oocyte (egg), and then it passed from the quantity of oocyte. If we have more than 15 oocytes, this means that we have very high oestrogen in our body and our endometrium is over stimulated, and it has a worse receptivity than in cryo cycle. So, in the case that we have, or high progesterone before that, the egg collection. Or we have more than 15-20 oocytes during the egg retrieval then we prefer also result if we have 5-6 oocytes then we do a fresh embryo transfer

Question:

I’ve tried short protocols; a layer biopsy came back normal. Could you please repeat the name of the medicine that will help the growth of a thin endometrium?

Answer:

Neupogen the name of the growth factor, is Neupogen.

Question:

Sometimes my period starts after I fly. Does it mean that I can lose my pregnancy if I fly? Is there any possibility to be sure that it is safe?

Answer:

During the procedures, during your natural cycle, you have hormones which are affected by the nervous system. So, if you have stress, your hormones also react to that stress and you have, you can have the possibility to have disorders in your cycle. When we do IVF procedures you have your hormones blocked, and we are putting our hormones in a stable dosage. So, you won’t experience those drops of hormones due to stress. Therefore, you can fly and everything will be ok. All our patient foreign patients fly, and everything is ok.

Question:

I would like to get hyaluronic acid in the knee for injuries for the inflammation in the knee to go down. Is it okay to get a frozen egg transfer only a few months later?

Answer:

Yes, hyaluronic acid doesn’t have an effect on the embryo transfer.
The question is only about your general condition. If your inflammatory process allows us to do the embryo transfer then yes, but hyaluronic acid doesn’t influence our process.

Question:

Does exercise during IVF attempt affect the implantation? I lack training but I get advice to stop training during IVF attempt. Do you advise that?

Answer:

We also advise to stop training because when you train, you can have cramps in the uterus. During the implantation it’s better to have a relaxed uterus, which prevents cramps. Because when you have contractions in the uterus, the embryo can move through the cavity and sometimes even can drop into the uterus tube, and we can have an extra-uterus pregnancy. So, it’s better to be relaxed during the two weeks of embryo transfer to have better chances. But there is no evidence and no investigation which show that training or not training is better for the implantation.

Question:

Do you do the endometrial scratching (scraping) during the pill cycle, which is the cycle before the real cycle? For instance, in case of cryo transfer, does it make sense, is it effective to do the scratching in the cycle when the anticontraceptive pill is being taken?

Answer:

About the scratching, contraceptive pills and scratching, they do not correlate. We use contraceptive pills just in case, to have your cycle plans and that’s all. About the scratching, we don’t use stretching in all cases of frozen embryo transfer. Why? We use scratching only in the cases when we have thin endometrium, when we have negative (unsuccessful) attempts, and we when we have suppressed immune system. We don’t use scratching for all patients, because if they have an aggressive immune system, stretching can even affect implantation, but not help.

Question:

Can too much progesterone post embryo transfer affect implantation?

Answer:

During IVF attempts we have standard progesterone dosages after the embryo transfer. They are checked by numerous tests and those level of progesterone can’t affect the implantation. The progesterone is for implantation, just to support the implantation.

Question:

Do you recommend immune test before IVF attempts?

Answer:

I guess so. We do immune testing for all our patients before IVF attempts. Even before the first IVF attempt. In Ukraine the patients are paying for their IVF attempts by themselves, so our main thing is to detect all factors, the most that can influence the IVF attempt, and just correct them so our patients all do immune testing before IVF attempts.

Question:

Which protocol do you recommend for donor egg cryo transfer?

Answer:

For us one protocol, this is the golden standard, but we need to understand that each first each patient is individualized. So, if we understand that the patient had problems with the thickness of endometrium, and had a thin endometrium before. Then it makes no sense to have the long protocol. If we understand that the patient has a good endometrium and antagonist shot will not decrease the thickness of endometrial then it’s better to have the one protocol.

Question:

How long does the Dipherlene 3.75 milligram shot work? For how many months or cycles?

Answer:

Dipherlene 3.75mg works for 28 days.

Question:

I had a Dipherlene shot end of August and was told the shot is still working and will still be working end of November. Is that true?

Answer:

It can be true if the dosage was 12mg.

Question:

What is Bioven when new used for and when should it be used before or after ET?

Answer:

Bioven is intravenous immunoglobulin, which we use in Ukraine, and we use it at the date of embryo transfer.

Question:

I’m 29, infertility is caused by a male partner. How many blastocysts do you recommend to transfer at once?

Answer:

We always discuss the quantity of embryos with the patient during the embryo transfer because it depends on the quality of the embryos and the age of the patient, and the situation also with her weight, for example, with her pathology. If she is healthy or has additional pathology. In your case, and we discussed, that if we will transfer two embryos, yes maybe we will have a slightly higher chances for the pregnancy. When we are pregnant with the twins, it’s harder to carry twins, and we have the higher risk of preterm labour and complications during the pregnancy. When we have singleton pregnancy, yes, the chances for the pregnancy are a little bit lower but still we have the higher chances to have a healthy baby. So, we recommend, let’s start with a transfer of one embryo and then when we try the next attempt, we discuss two embryos.

Question:

I’m 46-year-old, how many months preparation will I need, and what type of preparation if I have irregular period?

Answer:

If you are 46 years old and you have periods, we don’t need to do the preparation. We need to do ultrasound scanning and to see the condition of the endometrium, the thickness of the endometrium, the structure of endometrium and to do the investigations which are needed to go for IVF procedure. If we have a menopausal woman, then we need to prepare the endometrium for at least three months, just to have the good receptivity of the endometrium.

Question:

I am 43 and we are being told to use egg donor.

Answer:

Yes, because of age and I suppose because of your ovarian reserve. If we have above the embryo quality. The embryo quality, on the embryo quality influences the quality of the oocyte, we understand that the most high-quality embryo is at age, up to 35 years. Between 35 and 40, the woman is in a so-called grey area. This means that we have half and half. Half of the embryos will be healthy and half of them can have chromosomal disorders. So, after the age of 40 we have a crucial bad quality of the oocytes and we can have up to 80 percentages of chromosomal abnormalities in the embryo. So, if you want to have your own stimulation and you have good enough ovarian reserve so it’s better than PGS screening, this means that we can use preimplantation diagnostic and diagnosed the embryos for the chromosomal abnormalities, and only in case that we have the good quantity and healthy embryo we can do the embryo transfer. If you don’t have the possibility to do this due to a mesh level, the low ovarian reserve or due to financial questions then is better to have the egg donation program.

Question:

Using my husband sperm how do I start preparing myself my weight is 50 kilograms I’m a very slim person and it worries me, the medication I will be on, how I will affect my health?

Answer:

You’re talking about your stimulation work cryo cycle and egg donation. Because if you are talking about your situation, we will start stimulation with the FSH hormones. These hormones will cause the growth of your follicles, and the hormones don’t affect your weight and don’t affect your health. These are the same hormones which are produced by your body, but we input them in a higher dosage. So, your body is producing for one follicle, and we will work input for 10 follicles. Some of these hormones they don’t in fact affect the weight they influence only on the follicle growth. If we are talking about cryo cycle, and not your ovary stimulation, so you will be taking only oestrogen, and also in the low dosages. So, those medicine also can affect your weight, and can affect only what you are eating and that’s all.

Question:

If I have polyps as a practice to do an endometrial scrape and how long is it before attempting IVF?

Answer:

If you have polyps, the best option is to remove them. You can use the option of hysteroscopy for removing the polyps, and the best option is to do IVF attempt in the next cycle after hysteroscopy. The maximum – this is up to three months after the hysteroscopy.

Question:

What is the chance for the uterus with adenomyosis?

Answer:

It depends what kind what type of adenomyosis you have. How it is spread over the uterus. When you have adenomyosis, it slightly reduces our chances, but it has a straight correlation between the stage of adenomyosis and the pregnancy.

Question:

Do you do intralipid infusions in your clinic? As I was advised by a clinic coordinator you do not have that in your offer, but you use Bioven instead.

Answer:

Yes, we use Bioven instead because we have higher results, better results, on intravenous immunoglobulins, than on the intra lipids and that’s why we’re using Bioven.

Question:

What about painkillers with pregnancy?

Answer:

We can use aspirin during the pregnancy. When you have pain, it depends what kind of pain you have, and why you feel the pain.

Question:

What is the name of the immune test to check the immune system?

Answer:

Immunogram the test name is immunogram, and we search for NK cells, or maybe you have a separate test for NK cells. In Ukraine we don’t have for the separate test for NK cells. We have the general immunogram in which we detect NK cells, maybe in your country you have just NK cell testing.

Question:

I have done the pregnancy test which is positive, but because of the bleeding happening now, shall I go to emergency and I have a check-up? What shall I do?

Answer:

If you have a positive test, then first of all, yes. If you have severe bleeding, you do need to go to the emergency, and to have the medicine to stop the bleeding. The next step is to doublecheck the RCG level, and to understand if it’s increasing or not.

Question:

Do you use the NGS benefit when performing PGD testing?

Answer:

Yes.

Question:

What are the immune tests you recommend to do before IVF attempts?

Answer:

It depends on the case. If you have only having the first attempt, we recommend to do the NK cells test, and to screen the thyroid gland. If they have several negative tests, then in addition, we recommend to do SLA tests.

Question:

If have endometrial polyps, what do you suggest for getting the best IVF result?

Answer:

To remove further polyps, you need to remove the polyps and this will be the option to increase your chances for IVF.

Question:

Could you please explain what you mean with auto-aggression and endometrial scratching? May Hashimoto autoimmune disease have a negative influence on the scratching outcome?

Answer:

If we have aggressive scratching. How does scratching work? When we do scratching, we are just injuring the endometrium, and immunocompetent cells increase in the endometrium. So, we are activating our immune system if you have already Hashimoto after immune disease this means that your immune system is already aggressive. So, it makes no sense to do the scratching, because we already have your immune system aggressive. We need to suppress your system not to activate it.

Question:

What are we tablets to stop bleeding you mentioned?

Answer:

I don’t know if they are registered, and the name of them in Ukraine this is tranexamic acid. In most cases we use tranexamic acid.

Question:

How do you treat fibroids?

Answer:

It depends, if we have fibroids which are not in the cavity, then we can just leave them alone. If you have the opportunity to have the surgery for fibroids then we use the options to do the surgery for fibroids. if the fibroids are very big and we can’t do the surgery then we just leave them.

Question:

My diphereline shot was 3.75mg at the end of August, the transfer (fresh) was mid-September, but was unsuccessful. Now I am preparing for a second transfer it will be a cryo transfer, end of November. I was told the diphereline shot is still working and blocking my ovulation. I will not only take oestrogen and progesterone in this transfer cycle, now I am taking the contraceptive pill.

Answer:

In the instruction to the medical limitation is written that the diphereline works for 28 days, and when we plan the cycle, we calculate that the diphereline works for 28 days.

Question:

You mentioned not to have any cysts before transfer, does it matter with donor eggs?

Answer:

If you have a small size cyst, no. If you have a big cyst, it can have an influence, because if you will give oestrogen it can slightly grow. So, it’s better not to have cysts before the stimulation, or if we have a cyst not more than three centimetres. It will not influence the stimulation of the endometrium, but it can just grow and cause problems when you are pregnant.

Question:

Do the ERA tests act as a type of endometrial scratching? If I have been recommended to do ERA tests but I have high NK cells, is just likely to cause a problem?

Answer:

In your case ERA tests are diagnostic. So, if you have negative attempts, we need to understand what is going on. So, in your case you need to choose, you have risks, or you have benefits. In your case ERA test is a benefit, because you will know exactly the situation what is going on with your endometrium. Also, ERA test is like scratching, because you are putting the catheter inside and making movements inside the uterus causing trauma to the endometrium. But you can use options that you will do ERA test and you can, for just one month, have a rest, and have the program on the next cycle. In addition, if you have a higher NK cell count, we can use Bioven intravenous immunoglobulin and just correct the influence of the immune system.

Question:

Do you accept semen from the UK if the partner is not able to travel to Ukraine?

Answer:

Yes, we have our courier service. We can propose the option that our courier will come to the clinic, take the sperm, and bring it to Ukraine. So, it’s not a problem.

Question:

Have you had successful pregnancies with women like me with thin endometrium at your clinic?

Answer:

Yes. Several cases when we have very thin endometrium. We have one pregnancy at endometrium 5. One pregnancy it was in endometrium 5.5. Several within endometrium 6. So, sometimes if they have a good structure good, triple lining endometrium but thin, sometimes we do embryo transfer. Just understand if it’s your maximum and we can’t get a higher one, we really have problems.
