In this session, Agni Pantou, M.D., Ph.D. Candidate in Obstetrics and Gynaecology at the University of Athens, Physician & Surgical Assistant at Genesis Athens Clinic has been talking about unexplained infertility and the role of laparoscopy in IVF.
It depends on what we mean by partially blocked tubes. Is it one of the tubes that are blocked, or under pressure, they open? However, if you’ve been through failed IVFs and ICSI transfers, I assume that you’ve been through an embryo transfer as well, or had a failure before that. I mean there are many different factors like if there was an implantation failure or did it failed at the fertilization stage because there is also the genetic factor, for example. If there were hydrosalpinx, the doctor for sure would have suggested removing the hydrosalpinx as it’s a very big factor to fail. I assume the endometriosis was diagnosed and treated by cauterization of the spots. It depends on how big the extent of endometriosis was, there is also a stop of the period to eliminate the very small spots that the surgeon cannot see.
As you already had a laparoscopy, you don’t need it again. If you had hydrosalpinx, then the doctor would have seen that. Endometriosis should have been cured. I assume there are also other factors that you should check as well.
If there is acute inflammation, so the patient would have big pain. In general, if PID is chronic, then it’s only seen under laparoscopy. An ultrasound would suggest there is a suspicion of adhesion, or hydrosalpinx could be seen. However, if there are no symptoms at all and just a chronic pelvic inflammatory disease, then it’s only seen by laparoscopy. It depends on if it’s acute or chronic inflammatory pelvic disease.
I assume that you had another laparoscopy because of the natural ectopic pregnancy. I assume you had a salpingectomy, so in that case, there’s always a bigger chance of having another ectopic pregnancy if there was already one. Either way, there is a little increase in the percentage of ectopic pregnancy after IVF.
If you’ve had already a history of ectopic pregnancy and salpingectomy, however, If endometriosis is there, it would be best if you also checked the uterine cavity. To see if there is some sort of endometritis if you haven’t done so already. It’s checked via biopsy of the uterine cavity, and if there is endometritis – there are certain antibiotic protocols that are used, and they’re out there to treat that before the next embryo transfer takes place. At least to increase the chances that everything is all right in the uterine cavity. I assume that you’ve also checked the genetic factors as well.
As you have already had an ectopic pregnancy, there is a slightly increased risk to have another one because of having the ectopic pregnancy in the first place, but it all depends on why you had an ectopic pregnancy. If it was because of chronic salpingitis that has changed the morphology of the tubes, or it just happened. There is always a risk of an ectopic with IVF? You are a bit more prone in case of salpingitis, so I guess with the laparoscopy that you will soon do, they will check the pelvic floor, and then I would highly suggest checking for endometritis too.
If the tubes are fine, the hysterosalpingography will show that they’re open, but if there is an alteration in the epithelium of the tubes, it is not visible via salpingography. It could happen because of a pelvic inflammatory disease or some kind of infection from the genital tract that alters the epithelial cavity. Those are tracheitis, endometritis, salpingitis, etc., all of them are kind of related. If you’ve been through some kind of infection at some point, and I don’t necessarily mean an infection, such as ureaplasma or mycoplasma, which could be the case as well. In case the flora is disturbed, then the naturally existing bacteria that we have in our epithelia could even cause a chronic inflammatory state. I would say that having a little sample from the uterine cavity checked to see if the flora is okay or not would also trigger the idea that maybe there is an inflammation that has gone through with your tubes, and if possible, treat it with antibiotics.
There is always an increased risk of ectopic pregnancy after IVF, and to a very big extent, that is because when we do the embryo transfer, the tubes are open, so when the embryo goes from the uterine cavity, there’s a chance that it goes through the salpinx. Then the salpinx and its layer push it back to the uterine cavity with the cilia. If these cilia in the epithelium of the tubes are affected, the embryo is stuck in between the cilia and the affected layer of the tube. This is how ectopic pregnancy occurs. If you’ve had an ectopic and if the tube was not removed, the risk is again the same. If there is an affected tube because of inflammation, endometriosis, or adhesions surrounding the tubes, which are changing the tube’s ovarian morphology and texture, there is always an increased risk, even in natural conception. IVF has just its own risk of an ectopic.
As I said, endometriosis does cause poor quality of the oocytes and poor fertilization rate, poor implantation rate. IVF does bypass the endometriosis to a very big extent, but not necessarily it would cause a poor quality of the oocytes. With supplements of estradiol and progesterone in case of the corpus luteum deficiency that is caused by endometriosis then, implantation, if it takes place, could be supported. There is a small percentage that endometriosis affects IVF, not a big percent. That’s why your doctor has told you that IVF surpasses endometriosis, but it does. As I said in the presentation, after certain attempts of IVF, instead of going through another and another psychologically wise, body-wise, and cost-wise it doesn’t make any sense.
There should be something there, an underlying disease such as endometriosis that should be cured. In order to investigate everything, a laparoscopy would be suggested, but it all depends on the age. If a woman is 40 years old and older, for example, it could be suggested again to have a laparoscopy. There is also the poor quality of the eggs because of age, so it depends, we put many factors together to make a conclusion and suggest to go through laparoscopy.
Not all patients go through that, mainly younger women, but of course, women after recurrent implantation failure of older age, but the hormonal profile is very important to see that is fine, we would not suggest laparoscopy to everyone. As you’re getting treatment for endometriosis by suppression to help you with an answer, I would need to know your age, I would ask how is your hormonal profile before suppressing, is the AMH fine because suppressing for a few months could also suppress the hormonal levels more, which would not be good as well. Even if you would go for IVF later on, so I would ask all these questions before giving a final answer.
I would say it is a 75% success rate with donor eggs and good quality sperm.
There is a possibility of checking day-3 embryos and have a biopsy on them. However, a biopsy at day-5 or day-6 during the blastocyst stage is mostly used. There is less risk of damaging the embryo during the biopsy itself. You need to wait for those results from the biopsy that you already had, and the doctor will guide you through the next steps, or else you can always try day-5 preimplantation screening. When we do PGS, it’s always better to have many embryos because from the biopsy and the screening, there are many different outcomes, so having a higher amount of embryos that are being tested, you’ll have a higher amount of embryos, that would be okay. The embryo transfer would be with 2 or 3 embryos at your age. There is a chance that even at least one embryo is good enough for transfer, and if everything else is fine, then the percentage of success rate could also be fair, it doesn’t have to be 2 or 3 embryos to have a good result, you just, increase the chances.
It’s quite difficult, I would say having a natural conception with all these factors. There is always inflammation in our mind because of the ectopic pregnancy and the recurrent implantation failures. I would say that you should keep going and have another attempt and check with your doctor if there is anything else you could do with the implantation failure before doing the embryo transfer. There is another test that you could check, which is the ER Map, or the ERA test, which would suggest the window of implantation, and by having this test, the physician would be more sure when to do the embryo transfer. You could also combine a biopsy sent for the ER Map with a biopsy sent for endometritis, and this is how you would have two biopsies but done in one day, and then you would know when the window of implantation is good, so the medication would be given accordingly.
NK cells you don’t really need to check I think, they’re not as high in the priority list of tests. There’s a very big debate about NK cells right now. If there is endometritis, you would cure it before you do the embryo transfer, and that will increase the success. That’s what we see almost every day in our clinic, we go through this protocol in those cases.
If your hormone levels are good, PCOS is a whole other chapter, it could cause the low quality of eggs, not necessarily but there is a chance that the eggs are affected, but if the hormonal levels are good, they’re not disturbed, then the chances of affected oocytes from PCOS are also getting lower. At the end of the day, if you have 5 mature eggs, then go ahead, you only need one to be implanted in your case, and I’m sure that your physician would take care of the whole picture of the PCOS. There are many different protocols for patients with PCOS, like slowly gathering the mature ones and then fertilizing them, depending on all the other factors that are surrounding your case, the embryo transfer should be successful.
Yes, we do. There is a consent that the patients are signing when they start with IVF. One of them would be to donate the embryo for research another would be to discard it. We are really trying to also promote an embryo adoption program. I would actually like to evaluate this with the law department of our clinic and get back to you with some more details as well.
A high level of testosterone could impact folliculogenesis, it could impact the quantity and quality of the eggs as well. DHEA is given sometimes as treatment, and it could help, but it all depends on what the level of testosterone already is, so in the case, of PCOS, for example, if that is the reason for high testosterone because there are many other reasons endocrinologically wise, I would suggest to have it tested simultaneously with a gynecologist and an endocrinologist so that they can see it and help you within with the levels of testosterone, it could certainly affect it.
It wouldn’t have a negative impact on the treatment, this is not the reason why the treatment was not successful to a big extent, it could help, but it wouldn’t sabotage the retrieval or the treatment. There are other reasons for that, mainly because of the age and the oocytes and the DNA of the oocytes gets slightly affected, and after the age of 40 the mutations are even higher, and there are more poor quality oocytes, it doesn’t mean that they are not mature ones and not good, but there’s a higher risk of having a poor quality oocyte resulting in the failed attempt.
Not necessarily, but it depends on the other hormonal levels and the reason why testosterone would be affected. If it’s PCOS or another reason for that, what other symptoms are there? It wouldn’t affect it as much, but endocrinologists would certainly, answer this question better, I’m sure.
