  1. Good afternoon Doctor,
    I have a question about taking birth control pills for about two weeks for an ivf treatment. Is it matter if we start taking these pills on third day of periods than day 5. Does it have any outcome on treatment. Or if this is only for scheduling purpose. My concern is if we start taking these pills late on day 5 so what about follicles if they already have grown at this point.
    Thanks!

    • If useds correctly (see below), the BCP has no adverse effect on outcome in that cycle of treatment.

      One often hears the expressed opinion that the BCP suppresses response to ovarian stimulation. This is not the case, provided that the BCP is overlapped with administration of an agonist (e.g. Lupron, Buserelin, Superfact) for several days leading up to the start of menstruation and the initiation of ovarian stimulation cycle with gonadotropin drugs. If the latter precaution is not taken, and the cycle of stimulation is initiated coming directly off the BCP the response will often be blunted and subsequent egg quality could be adversely affected. The explanation for this is that in natural (unstimulated) as well as in cycles stimulated with fertility drugs, the ability of follicles to properly respond to FSH stimulation is dependent on their having developed FSH-responsive receptors . Pre-antral follicles (PAF) do not have such primed FSH receptors and thus cannot respond properly to FSH stimulation with gonadotropins. The acquisition of FSH receptor responsivity requires that the pre-antral follicles be exposed to FSH, for a number of days (5-7) during which time they attain “FSH-responsivity” and are now known as antral follicles (AF). These AF’s are now able to respond properly to stimulation with administered FSH-gonadotropins. In regular menstrual cycles, the rising FSH output from the pituitary gland insures that PAFs convert tor AF’s. The BCP (as well as prolonged administration of estrogen/progesterone) suppresses FSH. This suppression needs to be countered by artificially causing blood FSH levels to rise in order to cause PAF to AF conversion prior to COS commencing, otherwise pre-antral-to –antral follicle conversion will not take place in an orderly fashion, the duration of ovarian stimulation will be prolonged and both follicle and egg development may be compromised. GnRH agonists (e.g. Lupron, Buserelin, Superfact) , cause an immediate surge in release of FSH by the pituitary gland thus causing conversion from PAF to SAF. This is why, women who take a BCP to launch a cycle of COS need to have an overlap of the BCP with an agonist. By overlapping the BCP with an agonist for a few days prior to menstruation the early recruited follicles are able to complete their developmental drive to the AF stage and as such, be ready to respond appropriately to optimal ovarian stimulation. Using this approach, the timing of the initiation of the IVF treatment cycle can readily and safely be regulated and controlled by varying the length of time that the woman is on the BCP.
      Since optimizing follicular response to COS requires that prior to stimulation with gonadotropins, FSH-induced conversion from PAF to AF’s first be completed and the BCP suppresses FSH, it follows when it comes to women launching COS coming off a BCP something needs to be done to cause a rise in FSH for 5-7 days prior to menstruation heralding the cycle of CO S.This is where overlapping the BCP with an agonist (e.g. Lupron/Superfact/Buserelin) comes in. The agonist causes FSH to be released by the pituitary gland and if overlapped with the BCP for several days and this will (within 2-5 days) facilitate PAF to AF conversion…. in time to start COS with the onset of menstruation. Initiating ovarian stimulation in women taking a BCP, without doing this is suboptimal
      I believe it to be essential regardless of the protocol of COS protocol being contemplated, for women who launching ovarian stimulation coming off a BCP to overlap with an agonist for several days in advance of initiating ovarian stimulation with the onset of menstruation,

  2. Hi,
    On the short GnRH agonist protocol with synarel, should the evening dose of synarel be used prior to evening HCG trigger? Will it interfere with the action of the HCG trigger if I did the evening synarel dose 2 hours prior to trigger? Many thanks, much appreciated.

    • 2.Short (“Flare”) GnRHa Protocol, often referred to as the “micro) flare” protocol involves initiating gonadotropin therapy commensurate with initiation of gonadotropin administration. The supposed objective is to deliberately allow Lupron to elicit an initial surge (“flare”) in pituitary FSH release in order to augment FSH administration by increased FSH production. Unfortunately, this “spring board effect” constitutes “a double-edged sword”. While it indeed increases the release of FSH, it at the same time causes a surge in LH release. The latter can evoke excessive ovarian stromal/thecal androgen production which could potentially compromise egg quality, especially when it comes to older women and women with DOR. I am of the opinion that by evoking an exaggerated ovarian androgen response, such “(micro) flare protocols” can harm egg/embryo quality and reduce IVF success rates, especially when it comes to COS in older women, and in women with diminished ovarian reserve. Accordingly, I do not prescribe such protocols to my IVF patients.

  3. Dear Dr. Sher,

    I have just hit 43 years old, I have a son conceived naturally on our first cycle when I was 35, and a missed miscarriage at 10 weeks when I was 39. We’ve been trying to have a second child since I was 38. I don’t have a condition that would explain my infertility, other than the age.
    Since then I’ve done 2 IUI, 5 IVF that never yielded more than day 2 embryos. In total 4 were transferred. Last year I moved on to donor eggs. I had 3 FETs with eggs from 2 different donors in total. They were all negatives.
    I am wondering now whether there is an underlying immunological issue beneath, aside from the age. What would be your opinion on it?

    Thanks in advance.
    Kind regards,
    Maja

    • This is likely a case of age + diminished ovarian reserve, rather than an implantation issue.

      The older a woman becomes, the more likely it is that her eggs will be chromosomally/genetically “incompetent” (not have the potential upon being fertilized and transferred, to result in a viable pregnancy). That is why, the likelihood of failure to conceive, miscarrying and of giving birth to a chromosomally defective child (e.g. with Down Syndrome) increases with the woman’s advancing age. In addition, as women age beyond 35Y there is commonly a progressive diminution in the number of eggs left in the ovaries, i.e. diminished ovarian reserve (DOR). So it is that older women as well as those who (regardless of age) have DOR have a reduced potential for IVF success. Much of this is due to the fact that such women tend to have increased production of LH biological activity which can result in excessive LH-induced ovarian male hormone (predominantly testosterone) production which in turn can have a deleterious effect on egg/embryo “competency”.
      While it is presently not possible by any means, to reverse the age-related effect on the woman’s “biological clock, certain ovarian stimulation regimes, by promoting excessive LH production (e.g. short agonist/Lupron- “flare” protocols, clomiphene and Letrozole), can make matters worse. Similarly, the amount/dosage of certain fertility drugs that contain LH/hCG (e.g. Menopur) can have a negative effect on the development of the eggs of older women and those who have DOR and should be limited.
      I try to avoid using such protocols/regimes (especially) in older women and those with DOR, favoring instead the use of the agonist/antagonist conversion protocol (A/ACP), a modified, long pituitary down-regulation regime, augmented by adding supplementary human growth hormone (HGH). I further recommend that such women be offered access to embryo banking of PGS (next generation gene sequencing/NGS)-selected normal blastocysts, the subsequent selective transfer of which by allowing them to capitalize on whatever residual ovarian reserve and egg quality might still exist and thereby “make hay while the sun still shines” could significantly enhance the opportunity to achieve a viable pregnancy

  4. Dear Dr Sher,

    I had a fresh embryo transfer of a Grade 2 embryo (early blastocyst) – the only surviving embryo out of 18 eggs. Embryo not pgs tested. I am 40 years old.

    My first hcg was excellent at 247 at 10dp5dt. It continued to double and 4500 a week later.

    I had my 6 week 3 day viability scan yesterday. I was told it’s looking good and baby’s heartbeat is 120. But CRL is measuring at 0.5mm which my RE says is 2 days behind (6 weeks 1 day) but is in the normal range and needs to be monitored so another scan rescheduled next week at 7 weeks 3 days.

    My questions are:

    Is it within the normal range to be behind by 2 days in an ivf pregnancy with exact dates?
    What’s the reason if so? Is it a sign of an impending loss due to chromosomal abnormalities despite great HCG levels and heart beat?

    There are conflicting reference tables for CRL measurements and according to the Monash chart I’m 1 day ahead. Which one is a reliable one?

    Thank you so much!

    • 1. Is it within the normal range to be behind by 2 days in an ivf pregnancy with exact dates?

      A: This is likely not consequential.

      2. What’s the reason if so? Is it a sign of an impending loss due to chromosomal abnormalities despite great HCG levels and heart beat?

      A: I am not convinced that any of these issues are more likely because of this finding alone!

      Good luck!

      Geoff Sher

  5. Hello Dr. SHer,
    I have a question about start of birth control pills before start of IVF treatment , is it matter if we start it on day 2 or day 5 of periods . Does it have any impact on overall ivf treatment? What day is better to start it.

    Thanks.

    • Any day prior to the 7th day is fine. It would in my opinion, not prejudice outcome at all!
