Transcript

Kevin Pho: Hello. Welcome to the present. Subscribe at KevinMD.com/podcast. Right this moment, we welcome Erica Bove. She is a reproductive endocrinology and infertility specialist. Right this moment’s KevinMD article is “Why do high-quality IVF embryos fail?” Erica, welcome to the present.

Erica Bove: Thanks, Dr. Pho. It’s so nice to be right here.

Kevin Pho: All proper. Let’s begin by briefly sharing your story. Then we’ll soar proper into your KevinMD article.

Erica Bove: Completely. I like to begin by saying I went to med college to be a psychiatrist. That is fascinating as a result of I’ve all the time been motivated by the emotional aspect and the motivational aspect of individuals. However after I went to medical college, I fell in love with girls’s well being and OB/GYN, particularly infertility drugs, to assist individuals construct their households.

As I began to get out into apply, I used to be having these conversations with my sufferers and feeling like I used to be not connecting. I used to be going by way of all the information, however the affected person on the opposite aspect of the dialog was struggling to assimilate the knowledge and to make empowered decisions. They had been in a tailspin.

Across the identical time, I used to be accessing teaching for my very own private causes, and I began to attach the dots. I assumed: “What my sufferers want to assist them make these empowered decisions is a few of these teaching instruments.” So I began experimenting within the clinic as a result of we will invoice based mostly on time. Hastily, my sufferers had been having these superb breakthroughs. That’s after I thought: “OK, there’s something substantial right here.” That’s after I determined to type my very own teaching apply known as Love and Science, the place I assist skilled girls construct their households.

Kevin Pho: All proper. Your KevinMD article is titled “Why do high-quality IVF embryos fail?” For many who didn’t get an opportunity to learn your article, inform us what it’s about.

Erica Bove: Completely. I’m a working towards REI doctor. I assist individuals fairly often to conceive with IVF. Individuals assume that our jobs are so completely happy, serving to individuals with their households. However I’ll say what I do with most of my time in my consultations is assist individuals assimilate unhealthy information and assist individuals perceive why their final cycle didn’t work. It’s devastating. Persons are usually spending $15,000, $20,000, or $30,000 of their very own cash per cycle. Success will not be assured. If you sit with these sufferers and {couples} and attempt to assist them perceive, it’s simply so multilayered and sophisticated.

There are a few papers which were printed in the previous couple of years as we have now gotten higher and higher about understanding the standard of our embryos. There may be nonetheless a sure share of embryos that simply don’t take. Making an attempt to know why is vital. The papers that got here out within the final couple of years stated that this phenomenon known as recurrent implantation failure is sort of uncommon. They acknowledged that 95 % of people that have had three chromosomally examined embryo transfers ought to have had an implantation after three transfers. Nonetheless, that has not been my expertise.

I made a decision to do a webinar for individuals on this state of affairs. Once I sat down and regarded into the information, I couldn’t imagine it. I don’t assume that information is extrapolatable for most individuals as a result of over 99.9 % of the individuals weren’t even in a position to be included within the examine. What I actually wished to do was say: “Hey, you aren’t a zebra. When you have had two or three euploid transfers and it’s not taking, possibly there may be extra testing that may be achieved. Perhaps there’s something that hasn’t been discovered.” Individuals begin to assume: “I’m not going to have the ability to have children. I’m not going to have the ability to construct my household.” They begin to really feel threatened, after which that begins this cycle of hypervigilance and worse outcomes. So that’s what I wished to do: say, “Don’t hold your hat on these research as a result of there may be extra to the story. There may be extra that may be achieved, and let’s determine how we may also help you construct your loved ones and never simply get scared by these numbers.”

Kevin Pho: Now, earlier than speaking extra about recurrent implantation failure, for individuals who aren’t conversant in IVF and what it entails, you talked about the financial price (tens of 1000’s of {dollars}), however for these households which have implantation failure, let’s speak about a few of the emotional experiences that they undergo after this unlucky occasion.

Erica Bove: I simply obtained chills whenever you stated that as a result of it’s profoundly devastating. Initially, they’ve gone by way of IVF. They’ve spent all this time making ready to do that. The IVF course of itself takes about two weeks coming into the clinic each different day, getting blood attracts and ultrasounds that culminate in an egg retrieval. The particular person has egg retrieval beneath anesthesia, wakes up, and we inform them what number of eggs they’ve. These eggs are fertilized later that day with sperm. Then individuals both could have a recent embryo switch in that very same cycle, or they may return a month or two later to do a frozen embryo switch. You’ll be able to see this has already spanned three or 4 months no less than of any person’s life.

So then they do the embryo switch, which is both rapid inside a number of days after the egg retrieval or a few months after the egg retrieval. Then they nonetheless have to attend 9 to 10 days to see if they’re pregnant. That “two-week wait” is a very onerous time as a result of it’s like: “Is that this stunning ball of cells that everybody says appears to be like so nice beneath the microscope going to develop into my youngster?”

If there’s a connection and we’re in a position to share the information, “Excellent news, you might be pregnant,” individuals nonetheless aren’t out of the woods. However no less than that step has labored. If we name any person and say: “I’m so sorry.” Generally, Dr. Pho, it’s their solely embryo. Generally we name them and say (and once more, I’m tearing up saying this as a result of it’s so emotional): “I’m so sorry this didn’t work.” There may be silence. Identical to anytime we get devastating unhealthy information, it takes the rug proper out from beneath us. So there may be that day, after which the times that come the place there may be a number of processing of feelings.

I feel the extra unhealthy information individuals get, the much less hope they’ve concerning the course of and the extra they begin to assume it isn’t going to work for them. This doesn’t simply have an effect on a person and their sense of self and their id. It impacts relationships. I’ve seen so many divorces occur within the context of those remedies. Generally the psychological load is simply so nice that individuals even drop out; the dropout price from therapy is so excessive. That’s a part of why I do that work as nicely. If individuals can keep within the recreation, if individuals can perceive their choices, their our bodies, and all these issues, individuals are really possible to achieve success in the event that they keep it up. However when individuals drop out as a result of it’s so emotionally insupportable, that’s when it’s actually onerous. My aim is to make this a extra holistic expertise so individuals don’t should endure a lot and we will say: “OK, let’s zoom out. Let’s take a look at the large image and assist individuals navigate the storm.”

Kevin Pho: Now, what does the information say when it comes to the frequency of recurrent implantation failure? And do you assume that the frequency is extra frequent than that information suggests?

Erica Bove: Sure. There’s a examine (it was a retrospective examine, however nonetheless a examine) that confirmed that after three euploid, which suggests chromosome-tested, embryos, 95 % of sufferers had had an implantation, and 92 % of sufferers had had a dwell start. There was one other examine, a follow-up examine that introduced that out to 5 euploid transfers and confirmed that roughly 98 % had achieved their aim. That’s the place individuals say: “Why am I within the 5 %? Why am I within the 2 %? Why isn’t this taking place for me?”

Generally it’s even quite simple, Dr. Pho. It’s like: “Oh, you have got persistent endometritis. We are able to deal with that with antibiotics.” Then we clear it, after which their subsequent switch is a dwell start. I feel that’s what the information suggests. However whenever you take a look at the nice print of the examine, they excluded lots of people. They excluded individuals with adenomyosis, which is quite common for ladies. They excluded donor egg cycles. They excluded all types of extreme male components within the second examine. So whenever you begin happening the listing, you ask: “OK, the affected person in entrance of me, does this apply to them, or is there extra that we will do?” And I’ll let you know, there may be often extra we will do.

Kevin Pho: And earlier than speaking about what extra we will do, what would you say are a few of the extra frequent the explanation why girls have recurrent implantation failure?

Erica Bove: Positive. It’s twofold. When I’m sitting in my clinic fascinated by this with {couples} and households, I feel: “OK, is it the embryo or is it the uterus? Or is it each?” We now are in a position to check embryos. However what we’re realizing is that typically our testing is inaccurate, so typically it’s higher to not check the embryos. There may be all of the complexity: Simply because it says that this can be a euploid embryo doesn’t essentially imply it’s competent. It doesn’t essentially imply that that’s the fact. There are check traits the place that will not be true, and so typically much less is extra. So embryo points is without doubt one of the issues.

However I’ll say when any person has had a number of examined or high-quality embryos that aren’t implanting, there may be often one thing both with the uterus or one thing systemic that we have to tackle. One of many frequent issues is adenomyosis or endometriosis, which could be suppressed by a GnRH agonist for 2 or three months, typically even with an aromatase inhibitor as nicely. As soon as you may calm that hormonally responsive tissue (the endometriosis, the endometrial adenomyosis, which are sometimes comorbid), you will notice a rise in individuals’s probability of success.

Then it’s like: “OK, nicely how do you diagnose it? Do you do surgical procedure? Do you do that receptive testing?” So there are some nuances to it. However even empiric therapy with the GnRH agonist has been proven to largely enhance outcomes. Similar factor with persistent endometritis. We are able to diagnose that both histologically on an endometrial biopsy or visually with the hysteroscope. I love to do each myself. However once we deal with it and clear it after which we do one other switch, success charges are increased.

These are a few issues. I’ve seen individuals with fibroids. We additionally take into consideration the construction of the uterus. I noticed one lady; she had had three or 4 euploid embryos that had been transferred and it wasn’t working. She was a doctor as nicely, a radiologist. I stated to her: “I do know you have got had all this therapy and we haven’t talked to you about this.” (I used to be becoming a member of the apply; I hadn’t been taking good care of her all alongside.) I stated: “However I feel you want a myomectomy.” She had a myomectomy, after which her second switch after the myomectomy took. She ended up having twins.

So it’s a kind of issues the place you actually should be thorough and curious. Additionally, from a affected person advocacy perspective, ensure that the connection along with your fertility specialist is a stable one. I feel most fertility specialists have a vested curiosity in you and need to use this thorough and curious method. Generally it’s not a great match, and I feel individuals actually do have to tune into that voice and typically search a second opinion as a result of there’s a physician who will determine this out for you. It simply may take a bit extra time and a bit extra openness.

Kevin Pho: When it comes to normal of care, like what you might be suggesting when it comes to the workup and potential therapy approaches, is that a part of normal of care? Or is that one thing that’s extra cutting-edge, or one thing that’s not at present being achieved?

Erica Bove: That’s such an incredible query. A few years in the past, ESHRE, one of many European societies, got here out with a advice for recurrent implantation failure. I feel it’s difficult as a result of no one agrees on the definition of what that’s. You’ll be able to put it at two or three euploid embryos. What they are saying of their examine and their guideline is that whenever you count on that any person “ought to have conceived by now,” it’s time to look into it. They’ve a complete equation of whenever you begin this.

However they divide it into three tiers, which I like. They are saying: “We suggest these few issues: way of life, and apparently, antiphospholipid antibody testing as a result of it has been proven that if individuals’s blood stream is best, outcomes enhance.” The embryo is really in search of blood stream to outlive. So if any person has an impairment of their blood stream, you may give Lovenox and child aspirin with enchancment in outcomes. So there are a few issues which were proven to be useful, after which there are some things which are within the grey zone, after which there are a number of issues that aren’t really helpful.

The ESHRE guideline is how I apply. I’ll say more often than not I’m doing what’s really helpful after which exploring the grey to attempt to perceive the total image, like thyroid testing and endometrial testing and people types of issues. However a number of the stuff that sounds prefer it has promise, like pure killer cells and HLA markers and this entire discipline of reproductive immunology, has not been proven to be efficient, although there could also be promise sooner or later. So I often counsel sufferers concerning what I feel is evidence-based, what I feel will not be evidence-based, and supply the best-tailored plan transferring ahead.

Kevin Pho: If somebody involves you with recurrent implantation failure and also you do an intensive diagnostic workup and implement some therapeutics, what’s your success price when it comes to bettering that consequence?

Erica Bove: It is vitally excessive. I’d say fewer than 10 % of my sufferers are unable to fulfill their aim finally. Generally it means a unique frozen embryo switch protocol the place we have to get the uterine lining thicker. That is without doubt one of the high issues that the ESHRE guideline recommends: uterine thickness. Some individuals actually battle with that. However I feel that success charges are usually fairly excessive so long as we’re in a position to meet sure standards with endometrial thickness and high quality embryos.

It’s fascinating; for most individuals, embryo era appears to be the rate-limiting step of IVF. However as soon as you might be producing good embryos and they aren’t taking, then you definitely actually have to know what’s going on deeper. I’ll usually give a few months of Lupron. I’ll ensure that they don’t have any endometritis inflicting irritation of the uterine lining as a result of these are low-hanging fruit they usually actually could make a giant distinction.

Kevin Pho: In your article, you speak about a statistic concerning feminine physicians having increased infertility charges, and that’s definitely a hanging statistic. So what does that inform us concerning the influence of issues like way of life and high-stress careers on fertility?

Erica Bove: Sure. It’s such an incredible level. I feel that stress is actually onerous to measure, however I feel we’re getting higher at it, particularly as all of us have these wearable units and we’re getting extra real-time information. However it’s simple that feminine physicians have worse fertility outcomes. It’s not simply childbearing both. Individuals say: “Oh, it’s as a result of your surgical procedure residency and fellowship took 9 years mixed, and you might be 39.” When you even age-match individuals and take a look at a 35-year-old to 35-year-old feminine doctor, they’ve worse outcomes.

I imagine that is because of stress. Our jobs carry a giant load. It’s inherently tense to care for sufferers and households. Although it’s so rewarding, typically the care could be very tense for a lot of causes. A variety of instances our sleep cycles are dysregulated, so we’re up for lengthy durations. Particularly if you’re an attending and aren’t protected by these GME guidelines, we’re working for 30 hours straight, typically even 72 hours straight if you’re in sure fields. That isn’t good for the physique.

Most of my individuals and my sufferers and my shoppers are consuming nicely, they’re exercising, they’re doing all these issues. But when we don’t acknowledge that physiologically stress will increase cortisol ranges, and we all know that that has an impact on our fundamental physiology like our coronary heart price and our blood strain, we miss the total image. I actually imagine, and we have to examine this, that hypercortisolism negatively impacts uterine receptivity.

That is a part of what obtained me into this work: “Why are my feminine doctor buddies and colleagues at their fifth cycle and it’s not working?” However I’ll let you know, Alice Domar has achieved a number of this analysis, and I’m discovering it in my very own teaching apply. If you assist individuals join their minds and their our bodies, when you may lower their stress ranges, the success charges go up. We see increased implantation charges. We see increased ongoing being pregnant charges. There may be information to indicate this. We’d like extra, clearly. However that’s actually the factor.

If we’re speaking about uterine receptivity and why my high-quality embryos should not taking, we actually do have to take a look at stress because the variable that individuals aren’t speaking about to say: “That is, regardless that it’s onerous, modifiable.” There are well-documented research and techniques in 2025 when it comes to growing parasympathetic tone and serving to individuals join with their breath. So we will take a look at stress, we will deal with it. It does take possibly some onerous decisions and a few boundaries. However if you’re listening to this and that is your state of affairs, actually give it some thought as a result of stress is negotiable and we have now much more energy than we expect.

Kevin Pho: We’re speaking to Erica Bove. She is a reproductive endocrinology and infertility specialist. Right this moment’s KevinMD article is “Why do high-quality IVF embryos fail?” Erica, let’s have some take-home messages that you just need to go away with the KevinMD viewers.

Erica Bove: Positive. What I’d let you know, expensive listener, is that you’re by no means alone. I feel a part of what makes the fertility journey so onerous is that it’s extremely isolating. Perhaps all people in your world is getting pregnant and we’re approaching the vacations. What I’d say is you might be by no means alone. There are help teams that exist. There are therapists who perceive. There are fertility coaches who’re prepared to bridge you thru and grateful to take action. So discover the help you want, discover the group that you just want, discover the psychological well being help you want, as a result of whenever you do this, not solely will it really feel higher for you, however it’s going to assist your journey.

The second factor I’d say is: Give your self grace. One factor I’ve realized from doing this work over a decade is individuals blame themselves. They’re like: “Oh, it’s my fault. It’s as a result of I did X, Y, or Z, or as a result of I waited too late, as a result of I did all these various things.” Give your self grace. Conscious self-compassion is a talent, however that is completely not your fault. We honor that, we nourish that, and we come collectively and we bridge individuals to parenthood. It’s simply what we do.

Kevin Pho: Erica, thanks a lot for sharing your perspective and perception. Thanks once more for approaching the present.

Erica Bove: Thanks, Dr. Pho.
