The IVF cycle consists of the following stages:
At the initial stage of treatment, ovaries are stimulated by hormonal drugs to produce many ovaries. Should one consider that normally the female body grows and releases only one mature egg monthly, the development of more ovarian follicles is possible by administering hormones (a combination of GnRH and FSH analogues) inducing controlled ovarian stimulation to develop multiple ovarian follicles.Monitoring stimulation with a series of sonograms and hormonal determinations
Sonographic and hormonal determination is required to monitor stimulation and administer chorionic gonadotropin (hCG). Ovulation is induced by a midnight injection approximately 36 hours prior to the egg collection and completes the medication in the treatment protocol followed.
Approximately two hours before the egg collection, a sperm sample is collected from the wife’s husband. This samples is subjected to a special activation process, where the most mobile and healthy spermatozoa are selected. They remain in the lab in a nutrient until they are placed with the eggs. In case where no spermatozoa are found in the fluid, a testicular biopsy is performed.
