Official title
Assessment of the Role of Serum FSH Monitoring During Ovarian Stimulation and Identification of an Optimal Range for Expected Normal Responders
Overview
This study examines if monitoring serum Follicle Stimulation Hormone (FSH) levels can predict oocyte yield and progesterone levels, considering factors like age, baseline FSH, Antral Mullerian Hormone (AMH), antral follicle count, body weight, kidney function, and urinary FSH. The aim is to find a minimum FSH level that ensures optimal ovarian response and enables tailored FSH dosages for better outcomes.
Detailed description
Ovarian stimulation typically uses transvaginal ultrasound to monitor follicle growth and endometrial condition, with some clinics also tracking serum estradiol and progesterone levels, but often neglecting serum Follicle Stimulation Hormone (FSH). FSH is essential for follicle development, yet its levels can vary widely among women receiving the same dose due to factors like body weight, renal function, and ovarian reserve.
This study aims to identify a minimum effective FSH threshold that ensures optimal follicular growth while avoiding excess administration.
Interventions
- Drug Gonal-f (gonadotropin)
Women will be given 300 IU Gonal-F daily from cycle day 2 or 3. Gonal F will be injected at 8 pm daily. They will all receive cetrorelix acetate 250 mcg/day (Cetrotide) subcutaneously from stimulation day 5 onwards until and including the trigger day. Cetrotide will be administered at 08:00 am.
Primary outcome measures
- Quantitative Measurement of Serum Follicle-Stimulating Hormone (FSH) Levels During Ovarian Stimulation Using Serum Assays. [Time frame: 1 year]
