  1. Hello Dr,
    I have been reading your posts and appreciate your generous knowledge. I have only 1 embryo that was genetically tested and was “+X [mos] Low Level Mosaic”
    They informed us we have 30% chance for a healthy baby or 70% miscarriage. I am confused why they did not mention it resulting in a baby with either Triple X or Klinefelter syndrome? Is it certain it won’t result in a genetically abnormal baby? Would you advise to transfer?
    It was graded 6ab on Day 6.
    Thank you so much

    • I personally would advise against transferring this embryo.

  2. Hi Dr. Sher,
    My HCG test results –
    17/12 – 1665.5 mIU/ml
    19/12 – 2550.2 mIU/ml
    (4 w 4 d since last LMP)
    Is this a slow rise? Should I be worried?

    • I am not overly dismayed. Things could still be fine!

      G-d bless!

  3. I am 39 and had a failed IVF cycle recently. We collected 13 eggs but only 1 fertilized and then we did a FET, but it didn’t take. We are now preparing for another cycle and it has been recommended that we do ICSI and transfer 2 embryos, if we get more than 1 fertilized.
    What are your thoughts on transferring 2 embryos? I am hesitant given the risks however I am aware of my age as well and want to maximize my chances of having a baby. Any advice you can give would help. Thanks,

    • All multiple pregnancies pose a risk to both mother and offspring. Pregnancy induced maternal complications such as miscarriage, pre-eclampsia, antepartum and post-partum hemorrhage become progressively more prevalent the higher the multiple gestation. For the babies, it is an escalating risk of premature birth and intrauterine growth retardation that places the offspring at risk.

      While even twin pregnancies increase the risk to mother and babies, it is high-order multiples (triplets or greater) that prove to be most dangerous. In fact, in about 50% of such cases severely premature births that commonly occur in such cases, result in death or severe developmental complications such as cerebral palsy, psychomotor retardation, blindness and mental retardation; conditions which severely compromise the quality of life after birth and lead to devastating financial, social and societal hardship.

      Most women going through IVF are desperate to have a baby and many are even willing to cast safety to the wind, abandon all cautions, and virtually do anything it takes to achieve success. Such women are highly vulnerable to the (fortunately) few reckless medical practitioners who might exploit such desperation.

      IVF, because of an inclination on the part of many practitioners, to transfer multiple embryos at a time in the hope of improving success rates, has in the past contributed vastly in this regard. However, improving IVF technology and the ability to better identify “competent” embryos for transfer has in recent years resulted in a tendency to transfer only one or two embryos, leading to a significant decline in the incidence of high-order multiple IVF pregnancies. Notwithstanding this, the transfer >2 embryos at a time still takes place far too often and with a few exceptions (e.g. in older women with poorer quality embryos) can no longer be justified in my opinion.

      There is undoubtedly a need to better inform IVF consumers regarding the risks associated with the transfer of multiple embryos (especially >2) at a time. There is also an urgent need in the United States to introduce enforceable regulations to limit the number of embryos transferred, especially when it comes to embryos derived from the fertilization of young womens’ eggs, ) and when advanced embryos (blastocysts) are transferred.

      The introduction of advanced preimplantation genetic screening to identify those embryos that are most likely to propagate a viable pregnancy can more than double the IVF baby rate per embryo transferred. Yes, the time is fast approaching that the transfer of but one (1) embryo will result in one healthy baby more than 50% of the time. Indeed such genetic embryo testing can improve the efficiency of the IVF process reduce miscarriages and minimize the risk of chromosomal birth defects such as Downs Syndrome , thereby providing a “better way” to help patients safely build their families successfully.

      The high rate of multiple gestations resulting from IVF is a complex problem that can no longer be justified as an acceptable side effect of treatment. The Hippocratic oath states the cardinal rule of medicine as “primum non nocere; foremost do no harm.” It is imperative that this issue be addressed at multiple levels. This includes educating patients to the risks of high-order multiple gestations, as well as the steps practitioners can take to mitigate those risks, such as tailoring the treatment to the specific needs of each patient and limiting the number of embryos transferred. IVF Technology is one of the successes of modern medicine. It would be unfortunate if this success were to be overshadowed by the creation of an even worse problem. The challenge is ours.

    • I selectively, willingly transfer up to 2 embryos at a time.

      One of the commonest questions asked by patients undergoing IVF relates to the likelihood of their eggs fertilizing and the likely “quality of their eggs and embryos. This is also one of the most difficult questions to answer. On the one hand many factors that profoundly influence egg quality; such as the genetic recruitment of eggs for use in an upcoming cycle, the woman’s age and her ovarian reserve, are our outside of our control. On the other hand the protocol for controlled ovarian stimulation (COS) can also profoundly influence egg/embryo development and this is indeed chosen by the treating physician.
      First; it should be understood that the most important determinant of fertilization potential, embryo development and blastocyst generation, is the numerical chromosomal integrity of the egg (While sperm quality does play a role, in the absence of moderate to severe sperm dysfunction this is (moderate or severe male factor infertility a relatively small one). Human eggs have the highest rate of numerical chromosomal irregularities (aneuploidy) of all mammals. In fact only about half the eggs of women in their twenties or early thirties, have the required number of chromosomes (euploid), without which upon fertilization they cannot propagate a normal pregnancy. As the woman advances into and beyond her mid-thirties, the percentage of eggs euploid eggs declines progressively such that by the age of 40 years, only about one out of seven or eight are likely to be chromosomally normal and by the time she reaches her mid-forties less than one in ten of her eggs will be euploid.
      Second; embryos that fail to develop into blastocysts are almost always aneuploid and not worthy of being transferred to the uterus because they will either not implant, will miscarry or could even result in a chromosomally abnormal baby (e.g. Down syndrome). However, it is incorrect to assume that all embryos reaching the blastocyst stage will be euploid (“competent”). ). It is true that since many aneuploid embryos are lost during development and that those failing to survive to the blastocyst stage are far more likely to be competent than are earlier (cleaved) embryos. What is also true is that the older the woman who produces the eggs, the less likely it is that a given blastocyst will be “competent”. As an example, a morphologically pristine blastocyst derived from the egg of a 30-year-old woman would have about a 50:50 chance of being euploid and a 30% chance of propagating a healthy, normal baby, while a microscopically comparable blastocyst-derived through fertilization of the eggs from a 40-year-old, would be about half as likely to be euploid and/or propagate a healthy baby.
      While the effect of species on the potential of eggs to be euploid at ovulation is genetically preordained and nothing we do can alter this equation, there is, unfortunately, a lot we can (often unwittingly) do to worsen the situation by selecting a suboptimal protocol of controlled ovarian stimulation (COS). This, by creating an adverse intraovarian hormonal environment will often disrupt normal egg development and lead to a higher incidence of egg aneuploidy than otherwise might have occurred. Older women, women with diminished ovarian reserve (DOR) and those with polycystic ovarian syndrome are especially vulnerable in this regard.

      During the normal, ovulation cycle, ovarian hormonal changes are regulated to avoid irregularities in production and interaction that could adversely influence follicle development and egg quality. As an example, small amounts of androgens (male hormones such as testosterone), that are produced by the ovarian stroma (tissue surrounding ovarian follicles) during the pre-ovulatory phase of the cycle enhance late follicle development, estrogen production by the granulosa cells (that line the inner walls of follicles), and egg maturation. However, over-production of testosterone can adversely influence the same processes. It follows that COS protocols should be individualized and geared toward optimizing follicle growth and development time while avoiding excessive ovarian androgen (testosterone) production and that the hCG “trigger shot” should be carefully timed.
      In summary, it is important to understand the influence species, age of the woman as well as the effect of the COS protocol can have on egg/embryo quality and thus on IVF outcome. The selection of an individualized protocol for ovarian stimulation is one of the most important decisions that the RE has to make and this becomes even more relevant when dealing with older women, those with diminished ovarian reserve (DOR) and women with PCOS. Such factors will in large part determine egg competency, fertilization potential, the rate of blastocyst generation and indeed IVF outcome.

  4. Hi Dr Sher I am 39 years old, and had my 4th Egg retrieval and collected 8 Eggs but none of them were matured and no fertilization . My ER collected the Eggs while they were 16 to 18 MM . My previous round ( when I was 36) collected 12 Eggs and 8 were fertilized and the size were 18MM to 21 Mm with different clinic and different protocols. . My question is what can be the potential reasons for eggs are not mature at the time of collecting? is the IVF protocol or the age ? Or the eggs just got collected too early ?

  5. Hi Dr Sher , I had egg retrieval on the Nov 30 , got my period on the Dec 11, but I start to spotting and bleeding mildly again on Dec 18 again. Is it normal or something I should be concerned . Thank you very much

    • It is is probably innocuous but report this to your doctor for assessment!

      Good luck!
