PROTOCOLS FOR TREATMENT
The standard ovarian follicular stimulation protocol involves pituitary desensitization with a gonadotropin releasing hormone (GnRH) analog from the midluteal phase (days 16 - 25) in women with 28-day cycles and usually ovarian stimulation with human menopausal gonadotropin (hMG).
Usually the dose of gonadotropin depend on the patient's age and ovarian reserve assessments. Long-acting GnRH analogs give the same results as those administered daily form.
The main goal to match of donors and recipients protocol are to accurately plane visit of recipients clothe to day of hCG administration when the leading follicle is between 16 and 18 mm in diameter. Stimulation usually takes about 11–12 days.
LH surge is achieved with an injection of human chorionic gonadotropin (hCG) 10000. Oocyte retrieval is timed 32–36 hours after hCG administration under general anesthesia and under ultrasound guidance transvaginal needle aspiration with appropriate syringes. The oocytes are then fertilized with recipient's partner's sperm.
