Primary Outcome Measures
NameTimeMethod
Number of Participants With an Ongoing PregnancyApprox week 13; 9 weeks or more after the 1st positive pregnancy test

Number of participants who met human chorionic gonadotrophin (hCG) criterion, received an embryo transfer, tested positive with a serum pregnancy test 11-14 days after embryo transfer and had an ongoing pregnancy (defined as positive fetal heart action) at ≥ 9 weeks after the first positive pregnancy test.

Percentage of Participants With an Ongoing PregnancyApprox week 13; 9 weeks or more after the first positive pregnancy test

Percentage of participants who had an ongoing pregnancy ≥ 9 weeks after the first positive pregnancy test, as indicated by positive fetal heart action.

Secondary Outcome Measures
NameTimeMethod
Participants With Varying Numbers of Follicles That Were Greater Than or Equal to 17 MillimetersDay 7 and, if appropriate, every 2 days thereafter (Days 9/11/13)

The criterion for ovulation induction was three follicles ≥ 17 mm diameter as shown by pelvic ultrasound examination. Patients were assessed by pelvic ultrasound on the morning (prior to menotrophin or follitropin alfa administration) of Day 7 and, if appropriate, every 2 days thereafter (Days 9/11/13) until the criterion was met.

Participants With Varying Numbers of Oocytes RetrievedApproximately study day 15

Number of participants with grouped by the number of oocytes retrieved. Oocytes were retrieved following ovulation induction by subcutaneous administration of human chorionic gonadotrophin (hCG) in the form of choriogonadotropin alfa at a dose of 250 micrograms once participants reached the criteria of at least three follicles with \>= 17mm in diameter.

Participants With Varying Numbers of Pronuclear Stage OocytesApproximately study day 15

Number of participants with various groupings of pronuclear oocytes retrieved 16-20 hours after insemination.

Participants With Varying Numbers of Embryos TransferredApproximately study day 17

Number of participants with various categories of numbers of embryos transferred.

Participants With Varying Numbers of Embryos FrozenApproximately study day 17

Number of participants with different categories of number of embryos frozen.

Mean Number of Days Stimulated With Gonadotrophinsstudy days 1 - 13

Number of days stimulated with study drug until participant met the criteria for ovulation induction. Ovulation induction criteria is three follicles greater than or equal to 17 mm diameter as shown by pelvic ultrasound examination.

Pregnancy OutcomesApproximately 10 months

Long term follow-up to determine the outcome of the pregnancy.

Mean Endometrial ThicknessDay 7 or 9 or 11 or 13

Measurement performed on day of human chorionic gonadotrophin (hCG) administration/ovulation induction.

Mean Estradiol LevelDay 7 or 9 or 11 or 13

Measurement on day of human chorionic gonadotrophin (hCG) administration / ovulation induction.
