Pregnancy after 38: Advanced Maternal Age - Questions and Answers

Is there a limit of months to use Letrozole? Could it have bad side effects? Did I get it right that Letrozole keeps endometriosis lower in those months?

Currently, we now only use Letrozole for the stimulation for 5 days of the stimulation. Letrozole will maintain the endometrial sickness and with that, we can also increase the size of the follicles in all the women. We don’t use Letrozole for more than 5 days. Sometimes Letrozole is used in patients with breast cancer, and we need to stimulate women with breast cancer, we use it but only for the stimulation.

We don’t use Letrozole for months. We also use Letrozole in people who have severe adenomyosis, and we use it with Decapeptile, then we use Letrozole for at least 15 days or a month, but no more than that. It doesn’t mean that it has bad effects, but we don’t like to use that for too long because it has been demonstrated, it can help with that kind of period. We have good results with this time frame.

I’m 41, and I have done a few IVF procedures this year. I have 2 frozen embryos. When I was having the fertility treatments, my periods were regular (generally before that, as well). However, after I finished my last IVF round in July this year, my periods became irregular, and I have had no period for 2 months, and now I just have some brown discharge – no period. Is this normal? Do you think it might be a sign of perimenopause? Could I continue with another IVF round before implanting the embryos? My AMH was 3.59 pmol/ last year in March.

After an IVF treatment, you can have some irregularities with the periods, but it’s important to understand that after the age of 40, there is a drastic drop in the ovarian reserve, and sometimes it can be a sign of perimenopause. We can check it with an ultrasound scan or a blood test. Don’t worry because we can still go ahead with an IVF round, your AMH is low, but it doesn’t mean we won’t have any eggs. However, it’s completely normal that the first two months after stimulation, the periods can be irregular or heavier. If you have hot flushes, it means that your FSH level is very high and your ovarian reserve is low, but if we know that your FSH level is very high, we’ll try to use a protocol to decrease this FSH level to get as many eggs as possible.

Should I do hysteroscopy after 2 failed FETs? O HSG and a thin lining, I had an ovarian cyst in the past. Would I need to be asleep (big surgery), or is it enough to do a light version and then decide if I need to do the big one? My embryos were euploid.

The first thing we need to understand when we see an infertile couple is the reason the woman doesn’t get pregnant. Is it because of the male factor or her endometriosis, etc.? For example, just at the first consultation, we know that the woman didn’t get pregnant because she had severe and deep endometriosis and a possible male factor, and of course, an advanced maternal age. In your case, even if your embryos were euploid, it doesn’t guarantee a pregnancy 100%. We need to understand that because the quality of the embryo is important. Sometimes a low-quality embryo that suffers during a biopsy, then it’s frozen and thawed, because of that, we can lose potential implantation.

We need to check the quality of the embryos, and of course, it’s mandatory to check the fallopian tubes and the uterus. We use hysteroscopy as a diagnostic technique, we can see inside the uterus and try to widen the endometrial cavity, to make the uterus more receptive.

Not everybody can do the hysteroscopy, everybody knows how to do a hysteroscopy, but doing it well and performing hysteroscopy to try to direct the embryo to the area so it can implant is very difficult. If there are no experts at hysteroscopy at your clinic, my advice is not to do it. A good option is to check it with an MRI or with Hysterosalpingography (HSG) if there is any problem that can lead to the implantation failure.

I am due to try a long protocol this time with Diphereline on cycle day 21, but I don’t know when to start due to my irregular periods, spotting.

One thing to check is to perform an ultrasound scan just to confirm the ovulation, this is the first thing that can do. If you don’t have regular periods and don’t know if you are ovulating, they can give you the contraceptive pill, and therefore you can start with Diphereline.

Normally in a long protocol, we prefer not to give the contraceptive pill, but sometimes in people with very irregular periods or people with polycystic ovaries who have periods for 3-4 months, we give the contraceptive and therefore, we can plan the treatment.

I am trapped in a vicious circle. I have a high BMI, hence I got advice not to have an IVF until I lose weight. I am now 39, I have frozen embryos from when I was 36. Should I lose weight before frozen embryo transfer or given my advancing maternal age, give it a go. I’m worried that it won’t work and I lose my embryos. I am so stressed that I eat to comfort myself, but this doesn’t help. Any advice?

This is something that we should be aware of, it’s very simple to talk to a patient and say, you have to lose weight, but it’s never simple. We do need to know that a BMI over 32 decreases the number of eggs, the probability of implantation and increases the risk of miscarriage. Age is the most important factor, luckily you have embryos when you were 36, I don’t know your BMI. If it is your first embryo transfer, of course, and, your BMI is lower than 32, I would try to transfer an embryo.

If not, we need to focus on losing weight. If, for example, you’re worried about those 3 embryos, you can do and also it’s another stimulation to get as many embryos as possible, but from my point of view, we have a lot of people with high BMI that get pregnant as well, but they need to know that they have a 5% probability of bad luck, in that case, taking into account your BMI. If it’s over 35, my recommendation is to lose weight otherwise, the results will be probably bad.

I am 50, I have small fibroids, I had done hysteroscopy recently. I was given the go-ahead to proceed to FET with donor eggs, both unsuccessful. I have only 2 blastocysts left. What would you advise for my next transfer? I am on Aspirin, Clexane and Prednisolone protocol. You mentioned 2 mg of estrogen a day instead of 6, could that help?

The dose of estrogen depends on every woman. If we see that your endometrium is very thick, it means that we need to decrease the dose of estrogen. If we see that the endometrium is not thick enough, we need to increase it a little or change the way of the uterine preparation.

As you had 2 embryo transfers with an egg donation, we need to understand why they failed, we may be facing a uterine problem. We need to check the quality of the embryos, but I assume that as it was from an egg donor, the quality was fine. I assume that you got 4 blastocysts and 2 with a single embryo transfer, probably, so you only have two blastocysts left. I know you are 50 years old, and we always recommend doing a single embryo transfer, but in that case, as you have the only remaining blastocysts, which probably will be of worse quality, my advice would be to transfer both of them.

Regarding the uterine preparation, if they’ve done 2 FET attempts and they have not been successful, they need to change something, they need either change the uterine preparation, you can go ahead with a natural cycle or with a different way of taking oestrogens like vaginally, patches and they also need to study your uterus. If you have fibroids, you need to check where those fibroids are, if they are touching the endometrial lining if they are close to the endometrial cavity, this is very important. We need to check the fallopian tubes, also your thrombotic risk profile.

Do you recommend a long protocol for very low AMH?

It depends on the woman, I would never recommend a protocol without seeing a woman. It has been demonstrated that a long protocol in a low ovarian reserve has good results. In our clinic, we like to personalize the protocols, but it depends, most of the women coming to our clinic had previous failed treatments, so we need to change the protocol, we need to do something different. If they got a very good number of embryos or oocytes in the previous treatment, we will repeat it. We will change it if they had not been successful. The type of protocol depends on the characteristic of the patient, her ovarian reserve, her previous treatments and her age.

I’m 40, I have had 1 failed IVF cycle. I had an AMH level of 20, which I was told was high for my age. For that reason, quite a cautious approach was taken to the simulation. Only 4 eggs were retrieved, 3 fertilized, 1 embryo reached day-5. We had a frozen embryo transfer because it was thought that I might be overstimulated and be at risk of ovarian hyperstimulation syndrome. Unfortunately, no pregnancy. Now, we’re considering the flare procedure, but I am a bit concerned whether this is going from one extreme to the other? With an AMH level of 20, do you think the risk of OHSS with the flare protocols is high?

This is one of the things that happen a lot. People are very afraid of the polycystic ovary, and we don’t have to be afraid of it. In your case, you have a very good ovarian reserve, which means that we need to take advantage of that. We won’t give you super-high doses of hormones because we don’t want to cause a severe hyperstimulation syndrome, but in that case, with an AMH of 20 and having only 4 eggs, it means that the stimulation was done very badly. We need to take into account that in the polycystic ovary, the LH levels are very low, so it means that they need LH, they need, for example, Menopur.

They have changed to a long protocol, I think it’s a good solution because in your case, probably they gave you Decapeptyl, they didn’t give you Ovitrelle, that’s why you didn’t reach the LH level, so that’s why they retrieved only 4 eggs. That’s why it’s better to do a long protocol this time.
For people with polycystic ovaries, the long protocol is very good. Some clinics refuse to do it because of the risk of hyperstimulation syndrome. However, if we vitrify eggs, check estradiol level in each follicular tracking scan, if we try to prevent this hyperstimulation, I think we will have a good amount of eggs and therefore a good amount of embryos. At 40, we need to take into account your AMH level, and for that, we need to get as many eggs as possible and, therefore, as many embryos as possible.

My advice is, if you have more than 4 blastocysts, do PGS just to confirm that you have normal embryos, but don’t be afraid, you will feel bloated, you can feel a bit of discomfort, but just for a couple of days, we have several drugs to avoid this hyperstimulation syndrome.

Do you think egg quality can be affected negatively for an older woman by using a high dose of IVF drugs?

Yes, of course, it can happen, not that the egg quality can drop significantly, but it has been demonstrated that in people with a low ovarian reserve and older women, giving more than 300 units is a waste of money, and also it can cause adverse events. It can also impair the uterine quality, and it’s important not to increase the dose in older women. If the woman has a high BMI, we need to adjust these doses, but no more than 225 or 300 in that kind of patient.

I am 40, and I am having IVF on my own, I have had 5 failed IVF transfers, one fresh, three frozen. The last frozen transfer was with a different donor, and 2 day-5 blastocysts were transferred. I have 3 frozen embryos left, I had an ERA cycle which showed my lining was early receptive, so my last cycle transfer was 12 hours later but still was unsuccessful. What advice would you give me now on what to do? Would you advise any investigations before any other transfers?

Since they were blastocysts, and it was from an egg donor, it means that you have an implantation failure, and the reason is not the ERA test. The reason is beyond that, we need to check the uterus by doing an MRI, by performing a hysteroscopy just to rule out adenomyosis, endometriosis, endometritis, which is an inflammation or infection of the endometrium. We need to check the fallopian tubes, which are very often omitted and sometimes there is a hydrosalpinx or something wrong there that provokes this implantation failure. Once we remove these fallopian tubes, women get pregnant. We need to study the uterus, fallopian tubes, also check your thrombotic risk profile to be sure that there is no problem with your coagulation.

It’s important to check the quality of the embryos, if it was an egg donor, it would be good to check if this donor has previous pregnancy or previous cycles, we need to check if the quality is okay.

When we have 2 failed embryo transfers, it means that there is something wrong, and we need to focus on different things because it’s not just bad luck, it means that we are doing something wrong, and we need to investigate in other ways to find this issue.

It was my own eggs with a sperm donor.

In that case, it can be an embryo quality, the first thing is to perform PGS to confirm that the embryos are normal because, for example, if we do a cycle and we see that the embryos are chromosomally abnormal, it means that we are facing a problem of the ovarian quality. That is the reason for implantation failures. If we perform a cycle and you have normal embryos, it means that your previous embryo transfer was probably with normal embryos. We should investigate the other cause of implantation failure.

I’m planning on doing ERA (after 2 failed FETs). Would you also recommend doing ALICE and EMMA?

In our clinic (Juana Crespo), we don’t use the ERA test because it was a promising technique 10 years ago, but now it has been demonstrated that it doesn’t change anything. There are a lot of papers that confirm that the ERA test doesn’t increase the probability of pregnancy. We had a lot of patients who did the ERA test, and we decided to transfer the embryo when the patient was ready, and she got pregnant without taking the ERA test into account. Therefore, I do not recommend the ERA test because it won’t change it.

If you are planning to do an ERA test, you can. ALICE and EMMA are complementary techniques, they can check the microbiota, which is completely fine because if they see that there is something wrong, they can give you probiotics, or if there is an infection, they will give you antibiotics. If you are planning to do the ERA test, it is the same technique, so you can also do the ALICE and EMMA.

What would you recommend instead of the ERA test? Is there anything else or should I just skip it?

It’s the ultrasound scan and the hysteroscopy. I mean the eyes of the gynaecologist and the experience of the gynaecologist. In our clinic, for example, before putting an embryo the day of scheduling the embryo transfer, we perform a diagnostic hysteroscopy, and we check the endometrium if this endometrium is fine without signs of endometritis, with a good shape and good colour, for us, it is more reassuring than the ERA test because it analyses a couple of genes but the endometrium changes every month. If your endometrium is pre-receptive, you don’t know if it will be the same next month. The best technique is to do the scan, and the hysteroscopy, which will show us that this endometrium will be in charge of allowing the pregnancy in the same cycle.

It was discovered that I had Hashimoto, which had healed by itself. Now I only have normal hypothyroidism for which I take medication and have a very good TSH level. Have my eggs already turned bad due to Hashimoto, or are they still good?

If your TSH level is okay, your eggs will be completely normal. Hypothyroidism hasn’t been related to bad egg quality, it can imply during the pregnancy or the neural development of the baby. A complete hypothyroidism disorder with a super high TSH level can compromise fertility because your menstrual cycle can alter, but if your periods are regular, don’t worry, the egg quality will not be affected because of it.

Do you do DHEA pretreatment in low ovarian reserve, and if yes, how long?

The answer is yes. It has been demonstrated that it can increase the oocyte number. For women with low ovarian reserve, every oocyte matters, so we give DHEA, we prefer DHEA to testosterone because sometimes the testosterone can provoke ovarian cysts which is not malignant. DHEA should be administered at least 21 days before the stimulation, so we start taking them the previous month of the stimulation and continue until we get embryos.
