This is an open-label, parallel-group, randomized, multicenter Phase III trial to compare the efficacy and safety of a single 250 microgram (mcg) subcutaneous dose of MSJ-0011 to a single 5,000 international units (IU) intramuscular dose of urinary human chorionic gonadotropin (hCG) in inducing ovulation in Japanese women diagnosed with anovulation or oligo-ovulation. Ovulation induction therapy will be undertaken with follitropin alfa. The primary objective is to show that MSJ-0011 is non-inferior to urinary hCG, as assessed by the ovulation rate.

Subjects who underwent ovarian stimulation with follitropin alfa according to a low-dose step-up protocol for maximum of 28 days will receive a single dose of 250 microgram (mcg) MSJ-0011 (choriogonadotropin alfa \[recombinant human Chorionic Gonadotropin, r-hCG\]) subcutaneously (SC) within 32 hours after the last dose of follitropin alfa administration unless dominant follicle reached a mean diameter of greater than or equal to (\>=) 18 millimeter (mm); not more than 3 follicles each with a mean diameter of \>=16 mm and serum Estradiol (E2) level within an acceptable range for the number of follicle present, and not more than 2,000 picogram per milliliter (pg/mL).
Subjects who underwent ovarian stimulation with follitropin alfa according to a low-dose step-up protocol for maximum of 28 days will receive a single dose of 5,000 IU u-hCG intramuscularly dose within 32 hours after the last dose of follitropin alfa administration unless dominant follicle reached a mean diameter of \>=18 mm; not more than 3 follicles each with a mean diameter of \>=16 mm and serum E2 level within an acceptable range for the number of follicle present, and not more than 2,000 pg/mL.
Low-dose step-up protocol involves starting dose of follitropin alfa as 75 International Units (IU) subcutaneously per day ,increments by 37.5 IU every 7 days (Day 8, 15, 28) will be done if no ovarian response will be observed for maximum of 28 days.

Percentage of Subjects With Ovulation Mid-luteal Serum Progesterone (P4) Level of Greater Than or Equal (>=) 5 Nanogram Per Milliliter (ng/mL) or Clinical Pregnancy
Ovulation was defined as mid-luteal serum progesterone level of \>= 5 ng/mL or clinical pregnancy. Clinical pregnancy was defined as the presence of at least a fetal sac on transvaginal ultrasound (TVUS).
Time frame: Mid-luteal phase progesterone assessed (Day 5 to 10) or clinical pregnancy (Day 35 to 42) post hCG treatment
Percentage of Subjects With Ovulation Mid-Luteal Serum Progesterone (P4) Level of Greater Than or Equal (>=) 9.4 Nanogram Per Milliliter (ng/mL) or Clinical Pregnancy
Ovulation was defined as mid-luteal serum progesterone level of \>= 9.4 ng/mL or clinical pregnancy. Clinical pregnancy was defined as the presence of at least a fetal sac on TVUS.
Time frame: Mid-luteal phase progesterone assessed (Day 5 to 10) or clinical pregnancy (Day 35 to 42) post hCG treatment
Mid-luteal Endometrial Thickness
Endometrial thickness was measured using TVUS.
Time frame: Day 5 to 7 post hCG treatment
Percentage of Participants With Biochemical Pregnancy
Percentage of subjects with biochemical pregnancy was assessed. Biochemical pregnancy was defined as any miscarriage without any evidence of a fetal sac on TVUS on the Day 35 to 42 post hCG treatment, but with a positive serum β-hCG pregnancy test on Day 15 to 20 post hCG treatment (Beta-hCG level greater than \[\>\] 10 IU/Liter)
Time frame: Day 35 to 42 post hCG treatment
Percentage of Participants With Clinical Pregnancy
Percentage of subjects with clinical pregnancy was assessed. Clinical pregnancy was defined as the presence of at least a fetal sac on TVUS.
Time frame: Day 35 to 42 post hCG treatment
