Brief summary:
This is a randomized open-label study to compare between in-vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI) outcomes of the two regimen of Cetrotide® (Cetrorelix acetate) which are 0.25 milligram (mg) used from Day 1 or Day 7 of the menstrual cycle (Day 0 or Day 6 of stimulation) in polycystic ovarian (PCO) women in assisted reproductive technology (ART).

Detailed description:
Polycystic ovarian syndrome population is an androgenic syndrome characterized by a wide spectrum of clinical manifestations such as obesity, hirsutism, insulin resistance, diabetes and presence of specific ultrasonic features.

Cetrotide®, cetrorelix acetate, is an antagonist of luteinizing-hormone-releasing hormone (LHRH). Cetrotide® is registered in 70 countries (including France) for the prevention of premature ovulation in subjects undergoing a controlled ovarian stimulation, followed by oocyte pick-up and ARTs. Ovitrelle®, active ingredient human chorionic-gonadotropin alfa, is administered to trigger final follicular maturation and luteinization after stimulation of follicular growth.

OBJECTIVES

Primary objective:

* To compare the hormonal level of plasmatic estradiol on the releasing day (day of r-hCG administration) induced by Cetrotide® 0.25 mg/day started on Day 1 (Group A: Day 1) or on Day 7 (Group B: Day 7) of the menstrual cycle (Day 0 (S0) or Day 6 (S6) of stimulation) in PCO subjects undergoing IVF/ICSI procedures.

Secondary objectives:

* To compare the hormonal changes during the stimulation induced by Cetrotide® in A and B Groups
* To assess by ultrasound scans (US) the follicular development induced by Cetrotide® in A and B Groups
* To assess biological and clinical outcomes induced by Cetrotide® in A and B Groups
* To monitor safety of Cetrotide in A and B Groups

The trial will be conducted on an outpatient basis. Once each subject has met all eligibility criteria, they will be randomly assigned in one of the two treatment groups.

Arms:
arm 1: None arm 2: None

Interventions: intervention 1: Cetrorelix acetate intervention 2: Cetrorelix acetate intervention 3: Recombinant Human Choriogonadotropin (r-hCG) intervention 4: Recombinant human follicle stimulating hormone (r-hFSH)
Intervention descriptions: intervention 1: Cetrotide® 0.25 mg will be administered subcutaneously once daily from Day 1 (Day 0 of stimulation period \[S0\]) until r-hCG day (at least 2 follicles \>=17 mm) intervention 2: Cetrotide® 0.25 mg will be administered subcutaneously once daily from Day 7 (Day 6 of stimulation period \[S6\]) until r-hCG day (at least 2 follicles \>=19 mm) intervention 3: The r-hCG will be administered subcutaneously as a single dose of 250 microgram (mcg) on r-hCG day intervention 4: Recombinant human follicle stimulating hormone (r-hFSH) will be administered subcutaneously at a dose between 75 and 187.5 international unit (IU) once daily from Day 2 (Day 1 of stimulation period \[S1\]) until r-hCG day
