Hi Dr Sher, is it worth doing a DNA fragmentation test to see if the sperm could be causing chromosomal abnormalities in an embryo? My clinic doesn’t seem to do polar body biopsies – they advised me that it would not give useful information as abnormalities can still occur after the embryo is formed.
Many thanks! Sheena
That is true but it is the egg not the sperm that in >80% of cases determined embryo/blastocyst competency.

Hi Dr. Sher,
I did an IVF stim cycle and ended up with four healthy PGD-tested embryos. My first two FETs ended in chemical pregnancies. They were both natural cycles, with a lining of 7.2. My doctor concluded that the lining might be the problem. I have two embryos left now, and I’ve had two FETs canceled for thin lining. In one case, I did a full medicated cycle with a high dose of estrogen patches and lupron injections, plus Viagra. My lining still only got to 7.2. I have tried acupuncture, supplements, medication. My doctor says my lining just might not ever get thicker than 7.2 and we should move forward with another transfer. Do you agree? Thank you!
In my opinion, a lining of <8mm is highly u nlikely to result in a viable pregnancy. However, sometimes the protocol used for preparing the uterus for FET or the protocol employed for stimulation can be the cause of the this lining. Perhaps we should talk.

I am 34, and have had 2 miscarriages in the past 9months, with the first one occurring naturally. The second mc started naturally, then required a d&c. After the d&c, my hcg was still rising, and I was given a methotrexate shot due to residual tissue not in my uterus. After no period for several months, I had an saline infused sonogram done which revealed a complete blockage due to uterine adhesions. I underwent an operative hysteroscopy and the surgery was successful, and my doctor said the adhesions were easy to break up, but we’re mod-severe and throughout most of my uterus. I have since been put on 2mg estradiol daily to help build uterine lining to prevent regrowth. I have had some light intermittent spotting, but still no period. I have been tracking my ovulation and have not ovulated since the procedure. My questions are, can a hysteroscopy cause anovulation for a cycle? Will another hysteroscopy make it less likely that the adhesions will reform? Is there anything additional I can do besides estradiol to prevent reformation of the adhesions? Also is it still possible to conceive and carry a child to term after having mod-severe uterine scarring?
There is a strong possibility that the post-abortal inflammation (endometritis) that led to the intrauterine adhesions destroyed your endometrium rendering it unable to generate a lining that can menstruate and that the absence of your period , rather than being due to failure ovulate is due to end-organ endometrial insufficiency. If so, even though the visible scarring was removed surgically, might not be able to restore viability of your germinal (basal) endometrium. In such cases, the only ultimate recourse is gestational surrogacy.
A normal uterine cavity and endometrial lining are essential in order to conceive and maintain a pregnancy. Scar tissue in the uterine cavity (Asherman’s syndrome) can interfere with conception, or increase the risk of miscarriage. The condition is often so severe that it destroys most of the basal (germinal) layer of the endometrium from which the uterine lining (endometrium) develops each month. When most of the basal endometrium is incapacitated, no regeneration of the endometrium can take place and amenorrhea (cessation of menstruation) or infertility can follow. The condition often results in fusion/adhesion of the opposing endometrial surfaces, but can also simply destroy the basal layer of endometrium without resulting in adhesions (non-adhesive Asherman’s).
Asherman’s syndrome most commonly results from post-partum or post-abortal inflammation involving the uterine lining (endometritis), but it can also occur (although infrequently) following uterine surgery such as removal of fibroid tumors (myomectomy) that encroach upon (or penetrate into) the uterine cavity.
The treatment of adhesive Asherman’s syndrome is resection of scar tissue by hysteroscopy. A hysteroscope is a telescope-like instrument that is introduced via the vagina and cervix into the uterine cavity allowing visualization of and access to the entire uterine cavity, enabling surgical resection of scar tissue. The objective is to remove as much scar tissue as possible and to free adhesions that fuse the walls of the uterine cavity together, so as to enable viable basal endometrium to resume growth and progressively cover as much of the surface of the uterine cavity as possible. Post-operatively, a small balloon is often placed in the uterine cavity for a day or two, to keep the opposing surfaces separated in the hope of preventing recurrence of adhesion formation. The woman usually receives supplemental estrogen to encourage endometrial growth.
Endometritis of a severity sufficient to produce Asherman’s Syndrome often scars and blocks the uterine entrances into the Fallopian tubes. However it is not always the case. The lining can be damaged while the tubes remain open. In such cases, if the uterine lining cannot support proper embryo implantation, a pregnancy could still implant in a Fallopian tube leading to an ectopic (tubal) pregnancy. Unless it is diagnosed early (by blood testing in combination with ultrasound examination) and treated medically or surgically, the ectopic pregnancy will rupture with serious and potentially life endangering consequences.
About 8 years ago, we reported on the use of Viagra vaginal suppositories to improve blood flow and hence enhanced delivery of estrogen to the endometrium. In this manner, we have been able to improve endometrial development in about 75% of women who otherwise were unable to develop an “adequate” uterine lining. Most of these women had undergone several failed IVF attempts. Many of the women who were successfully treated with Viagra subsequently conceived following IVF and went on to deliver healthy babies. One such case immediately comes to mind. It involved a woman who was from Singapore and who following 15 failed IVF attempts due to poor endometrial development conceived on her first IVF-Viagra attempt with us following Viagra therapy.
But Viagra is often ineffective in thickening the uterine lining in women with Asherman’s syndrome. The reason is that with Asherman’s there is often such widespread destruction of the basal endometrium (from which fresh endometrial cells must be generated), that regardless of the improvement in uterine blood flow and improved estrogen delivery, the endometrium just can’t respond. In such cases, the woman should consider using a gestational surrogate or pursuing adoption.

Hi Dr. Sher,
I wanted to get your opinion. I am 32 years old with unexplained infertility. My husband sperm is perfect. We just did our first IVF. We had 22 follicles but when we went in for the retrieval we only had 3 eggs. All three fertilized. One did not grow and two did. Two transferred but BFN. We are about to do our second IVF and we are adding LH and doing the medicine longer. Should we expect different results?
Whenever a patient fails to achieve a viable pregnancy following embryo transfer (ET), the first question asked is why! Was it simply due to, bad luck?, How likely is the failure to recur in future attempts and what can be done differently, to avoid it happening next time?.
It is an indisputable fact that any IVF procedure is at least as likely to fail as it is to succeed. Thus when it comes to outcome, luck is an undeniable factor. Notwithstanding, it is incumbent upon the treating physician to carefully consider and address the causes of IVF failure before proceeding to another attempt:
1.Age: The chance of a woman under 35Y of age having a baby per embryo transfer is about 35-40%. From there it declines progressively to under 5% by the time she reaches her mid-forties. This is largely due to declining chromosomal integrity of the eggs with advancing age…”a wear and tear effect” on eggs that are in the ovaries from birth.
2.Embryo Quality/”competency (capable of propagating a viable pregnancy)”. As stated, the woman’s age plays a big role in determining egg/embryo quality/”competency”. This having been said, aside from age the protocol used for controlled ovarian stimulation (COS) is the next most important factor. It is especially important when it comes to older women, and women with diminished ovarian reserve (DOR) where it becomes essential to be aggressive, and to customize and individualize the ovarian stimulation protocol.
We used to believe that the uterine environment is more beneficial to embryo development than is the incubator/petri dish and that accordingly, the earlier on in development that embryos are transferred to the uterus, the better. To achieve this goal, we used to select embryos for transfer based upon their day two or microscopic appearance (“grade”). But we have since learned that the further an embryo has advanced in its development, the more likely it is to be “competent” and that embryos failing to reach the expanded blastocyst stage within 5-6 days of being fertilized are almost invariably “incompetent” and are unworthy of being transferred. Moreover, the introduction into clinical practice about a decade ago, (by Levent Keskintepe PhD and myself) of Preimplantation Genetic Sampling (PGS), which assesses for the presence of all the embryos chromosomes (complete chromosomal karyotyping), provides another tool by which to select the most “competent” embryos for transfer. This methodology has selective benefit when it comes to older women, women with DOR, cases of unexplained repeated IVF failure and women who experience recurrent pregnancy loss (RPL).
3.The number of the embryos transferred: Most patients believe that the more embryos transferred the greater the chance of success. To some extent this might be true, but if the problem lies with the use of a suboptimal COS protocol, transferring more embryos at a time won’t improve the chance of success. Nor will the transfer of a greater number of embryos solve an underlying embryo implantation dysfunction (anatomical molecular or immunologic).Moreover, the transfer of multiple embryos, should they implant, can and all too often does result in triplets or greater (high order multiples) which increases the incidence of maternal pregnancy-induced complications and of premature delivery with its serious risks to the newborn. It is for this reason that I rarely recommend the transfer of more than 2 embryos at a time and am moving in the direction of advising single embryo transfers …especially when it comes to transferring embryos derived through the fertilization of eggs from young women.
4.Implantation Dysfunction (ID): Implantation dysfunction is a very common (often overlooked) cause of “unexplained” IVF failure. This is especially the case in young ovulating women who have normal ovarian reserve and have fertile partners. Failure to identify, typify, and address such issues is, in my opinion, an unfortunate and relatively common cause of repeated IVF failure in such women. Common sense dictates that if ultrasound guided embryo transfer is performed competently and yet repeated IVF attempts fail to propagate a viable pregnancy, implantation dysfunction must be seriously considered. Yet ID is probably the most overlooked factor. The most common causes of implantation dysfunction are:
a.A“ thin uterine lining”
b.A uterus with surface lesions in the cavity (polyps, fibroids, scar tissue)
c.Immunologic implantation dysfunction (IID)
d.Endocrine/molecular endometrial receptivity issues
Certain causes of infertility are repetitive and thus cannot readily be reversed. Examples include advanced age of the woman; severe male infertility; immunologic infertility associated with alloimmune implantation dysfunction (especially if it is a “complete DQ alpha genetic match between partners plus uterine natural killer cell activation (NKa).

I also suggest that you access the 4th edition of my book ,”In Vitro Fertilization, the ART of Making Babies”. It is available as a down-load through http://www.Amazon.com or from most bookstores and public libraries.
Hi Dr Sher, I have some questions about frozen embryos. First, how soon before the transfer is the embryo thawed? the same day or the day before? Secondly does it harm the embryo to be moved? My clinic is transporting my embryo from one clinic to another using a “Transporable Incubator” ready for the transfer. – Is this safe or OK?
We thaw the embryos on the same day as the FET. nd, no, done correctly, transporting embryos in the frozen state will not harm them.
