Does the Medical Tretament Prior to Stimulation Affect the Fertility Outcome in Cases of Endometriosis Associated Infertiltiy

Brief Summary

Detailed Description

Patients complaining of infertility due to endometriosis diagnosed by ultrasound or laparoscopic surgery will be randomly allocated to three groups : Group A: will receive COCPs for 3-6 months prior to starting IVF / ICSI cycle. Group B: will receive Dienogest for 3-6 months prior to starting IVF / ICSI cycle. Group C: will be subjected to direct ICSI /IVF cycle. Then all patients will be subjected to ovarian stimulation regimen using GnRH Agonist Down-Regulation Gonadotropin Stimulation-The "Long" Protocol. During the ovarian stimulation, the woman's response is monitored with serum estradiol levels and vaginal ultrasound examinations. The estradiol level is used to determine the dose of gonadotropins and whether under- or overstimulation occurs. The goal of the ovarian hyperstimulation is to develop at least three mature follicles that are 17 mm in diameter or larger. Once this is achieved, FSH and other medications are discontinued, and a single injection of hcg is given to mature the eggs to allow fertilization. The hcg administration will also cause ovulation, but this does not occur until 40 hours or later after the injection. Therefore, it is standard that the hcg injection is administered 36 hours before the scheduled egg retrieval such that this will allow adequate maturation of the eggs and yet there would be little risk of ovulation. Then the process will be continued through oocyte retrieval, oocyte maturation , fertilization by ICSI. Each group will be followed up to detect the number of oocyte yield, fertilization rate and availability of good quality embryos and then according to the results the effect of medical treatment prior to stimulation will be assessed.
