Crash IVF

Some women experience during IVF or ICSI treatment, that although they recieve high dosis of FSH, they do not produce a sufficient number of eggs for fertilisation. Thes women are classified as low responders. A subgroup of these women are caracterized by short menstrual cycle ( less than 27 days) and normal FSH and LH in the blood. They are not in premenopause.

These women are caracterized by selecting a dominant follicle already before menstruation. Therefore we utilized the antagonist GnRH antagonist Ganirelix, 7 day before expected menstuation. This induces a menstruation early and allows us to strat FSH stimulation earlier. Therefore will more an better oocytes be preserved for IVF.

The treatment schedule is as follows:

When the women start menstuating shes is schedules for the first visit 21 days later.
Here she gests the Ganirelix
On her second day of menstruation we start FSH stimulation
When the follicles are 14 mm in diameter an antagonist is again given paralell to the FSH stimlaton for some more days.
The ovulation induction is given when the follicles are 17 mm in diameter
