What about stimulation and monitoring of the ovaries in IVF ?

Let us first point out that this treatment will be adapted to the physiology of each patient and adjusted to the individual reaction of the ovaries. A special substance (GnRH agonist) will be given at the beginning of the cycle to put the pituitary secretions of FS H and LH to rest.

This drug is given either as a single intramuscular injection or in a nasal spray applied every 6 hours.

Later on, growth of the ovarian follicles will be artificially stimulated through daily injections of gonadotrophic hormones

Maturation of the follicles will be monitored from day 5 on :
  1. daily assays of oestrogen (= oestradiol) blood levels.
  2. daily ultrasound count and measurement of follicles done with a vaginal
    echographic probe.
