Conditions: Infertility
Allocation: RANDOMIZED | Intervention model: PARALLEL
Enrollment: 124
Healthy volunteers: no

Brief summary:
This study is aimed to demonstrate that highly purified Menotrophin produces significant lower progesterone serum levels during the follicular phase in comparison to Follitropin alpha in the treatment of subfertile females undergoing an in vitro fertilisation (IVF) and to investigate if the progesterone serum levels might be a useful predictor for the success rate of the ongoing pregnancy rates

Detailed description:

Arms:
arm 1: Starting on Day 2 or 3 of the menstrual cycle, 150 IU (up to 300 IU) by subcutaneous injection once per day in the morning for up to 12 days until human chorionic gonadotropin (hCG) criteria are met. Pituitary down-regulation (cetrorelix), ovulation induction (choriongonadotropin), and luteal phase support (intravaginal progesterone) are administered the same way in both treatment arms. arm 2: Starting on Day 2 or 3 of the menstrual cycle, 150 IU (up to 300 IU) by subcutaneous injection once per day in the morning for up to 12 days until human chorionic gonadotropin (hCG) criteria are met. Pituitary down-regulation (cetrorelix), ovulation induction (choriongonadotropin), and luteal phase support (intravaginal progesterone) are administered the same way in both treatment arms.

Interventions: intervention 1: Menotrophin intervention 2: Follitrophin alpha intervention 3: Cetrorelix intervention 4: Choriongonadotropin intervention 5: Progesterone
Intervention descriptions: intervention 1: Starting on Day 2 or 3 of the menstrual cycle, 150 IU (up to 300 IU) by subcutaneous injection once per day in the morning for up to 12 days until human chorionic gonadotropin (hCG) criteria are met. intervention 2: Starting on Day 2 or 3 of the menstrual cycle, 150 IU (up to 300 IU) by subcutaneous injection once per day in the morning for up to 12 days until human chorionic gonadotropin (hCG) criteria are met. intervention 3: Participants self-inject subcutaneously Cetrorelix in the morning at a daily dose of 0.25 mg/day from Day 5 of gonadotrophin administration on and continue throughout the period of gonadotrophin treatment up to day 12 as a maximum. The last dose of Cetrorelix is given on the day of ovulation induction. intervention 4: 10,000 IU administered by the Investigator or designated personnel in the evening of the day on which the hCG criterion is met (no later than Day 13). The criterion for hCG administration is three follicles \>+17 mm diameter as shown by pelvic ultrasound examination. intervention 5: Vaginal gel progesterone is used once daily at a dose of 90 mg for a period of 30 days starting on the day of oocyte retrieval (approximately Day 14).
