Dear dr. Where,
On January 26 we transferred two 3 day embryos. It was a donor egg cycleOn February 3, 8dp3dt I got my fist ever positive beta hcg 66. A day after the beta hcg was 174. Today at 11dp3dt the beta hcg result is 558. How long, according to you, do I have to continue checking the beta hcg before I can start realistically hoping that this is a viable pregnancy?
Thank you.

Hi, iam 33 old, just had my PGD 5 day embryo transfer but got negative blood test. It was totally devastated. My doctor I. Melbourne said I had a good quality of embryo was transferred. Linning also up to the mark but still failed. Can u explain please?????
Whenever a patient fails to achieve a 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).
My answer to patients who ask me when is the time to stop undergoing IVF is …Aside from the weight of the financial burden, the time to stop is when in spite of thorough and comprehensive evaluation, there is no remediable and treatable explanation for repeated failure.

Hello doc…i am 14 days post a frozen transfer. I had fertigyn injections on day 4, 7 and day 10. on day 12 my HCG level was 341 and day 14 931. Are these good HCG level?
It could well be a good sign. Repat it in 2 days and if it doubles, that would be indicative of implatation. An Ultrasound done about 7-10 days from now might be definitive.

Dear Dr. Sher
Is there any method by which an immature egg retrieved can me matured in the lab and fertilised?
Yes! In some cases, keeping it in culture for a few hours will mature it up.

Dear Dr Sher,
1-Why is birth control or estrogen priming used in cycles? Is it possible to use only Gonal F for older patients (with DOR and high LH) from start of period till follicles are ready for trigger with Ganarilix used to prevent ovulation?
2-What purpose does Human Growth Hormone do to make a cycle more successful and how can it benefit older patients with DOR?
3- what is the maximum age you would use patient’s own eggs where there is some chance a good egg will result in viable pregnancy?
Kind regards
Jenny
1-Why is birth control or estrogen priming used in cycles? Is it possible to use only Gonal F for older patients (with DOR and high LH) from start of period till follicles are ready for trigger with Ganarilix used to prevent ovulation?
A: Anything is possible. However the BCP suppressed LH and reduces the effect of excessive LH on production of ovarian testosterone which can compromise egg quality. The estrogen priming sensitizes the ovarian follicles to FSH stimulation.
2-What purpose does Human Growth Hormone do to make a cycle more successful and how can it benefit older patients with DOR?
A: It purportedly stimulates mitochondial activity which fuels DNA synthesis in the eggs.
3- what is the maximum age you would use patient’s own eggs where there is some chance a good egg will result in viable pregnancy?
A: No absolute maximum, but I advise women over 43Y to seriously consider egg donation.
