Monitoring the Early Follicular Phase With Androstenedione in Low-dose Step-up Ovulation Induction in High Responders

50 patients with anticipated high ovarian response, who are being planned to be conventionally treated with low-dose step-up ovulation induction and intrauterine insemination will be analysed in this study. At every control day including the start day, blood samples taken for blood estradiol (and if required progesterone) measurements will be used to measure blood androstenedione and total testosterone levels, as well. Hence, we will have defined an early parameter for defining follicular response in the first 5-7 days of low-dose step-up ovulation induction. Low-dose step-up ovulation induction will be started at 50-75Units/day of rhFSH and the dose will be increased at not earlier than the 7th day at an increment of +37,5Units/day unless a response is observed ( which is at least a 10mm follicle, selected for growth). If more than 3 dominant follicles are selected, the cycle will be cancelled. Otherwise, when at least one follicle \>16mm is obtained, a 150Microgram sc. injection will be administered for ovulation trigger and intrauterine insemination made at the 34th-36th hours.
