Overview
The primary purpose of this trial is to investigate whether men with idiopathic infertility (unexplained reduction of semen quality), after being treated with a daily dose of 12 µg recombinant follicle stimulating hormone (rFSH) for 6 months, can improve the chance of spontaneous pregnancy observed in their female partners in comparison to placebo (inactive treatment).

Eligibility
Inclusion Criteria:
- History of infertility for 12-60 months with current partner at randomization.
- Men between the ages of 18 and 50 years.
- Total sperm count 5-39 million at screening; confirmed by two consecutive samples taken ≥2 weeks apart before randomization.
- Total motile sperm count of 5-16 million at screening; confirmed by two consecutive samples taken ≥2 weeks apart before randomization.
- Semen volume ≥1.4 mL at screening; confirmed by two consecutive samples taken ≥2 weeks apart before randomization.
- Serum follicle-stimulating hormone (FSH) levels of 1.5-8.0 IU/L (measured at central laboratory) at screening. (Approved in US: FSH levels of 2-12.0 IU/L (measured at central laboratory) at screening)
- Serum luteinising hormone (LH) levels of 1.2-7.5 IU/L (measured at central laboratory) at screening.
- Serum total testosterone levels of ≥300 ng/dL (equals ≥10.4 nmol/L; measured at central laboratory) at screening.
- Agree to have regular intercourse with current female partner with the intent of spontaneous conception within 9 months from randomization.
- Agree to provide information on female partner's positive urine pregnancy test(s) and documentation of ultrasound(s), delivery, and neonatal/infant health.
Current partner fulfilling the criteria below:
- Pre-menopausal woman between the ages of 18 and 35 years. (Approved in US: Pre-menopausal woman between the ages of 18 and 38 years.)
- Regular menstrual cycles of 21-35 days.
- No history or current condition of pelvic inflammatory disease, endometriosis stage II-IV by definite or empirical diagnosis, or tubal ligation.
- Agree not to obtain infertility treatment outside of this trial for 9 months from randomization of male subject. (Approved in US: However, after 6 months from randomisation, the subject's semen can be used in infertility treatment procedures of his partner.)
Exclusion Criteria:
- Previous FSH treatment not leading to conception. (Approved in US: Previous FSH treatment for ≥4 months not leading to conception.)
- Past or current use of finasteride within 3 months prior to screening.
- Any history of anatomical disorder of the pituitary gland or testes.
- Any structural abnormalities of the vas deferens (unilateral or bilateral) at screening.
- Any known, clinically significant, systemic disease in addition to the trial indication that might negatively impact fertility.
- Known history or presence of clinical varicocele (subclinical and Grade 1 varicocele are acceptable).
- Known history of cryptorchidism, testicular torsion, or orchitis.
- Known abnormal karyotype (including Y-chromosome microdeletion).
- Current or past treatment of urogenital (kidney, bladder, testicular, or prostate) cancer as well as history of chemo- or radiotherapy that can have impact on testes.
- Any known uncontrolled non-gonadal endocrinopathies (thyroid, adrenal, pituitary disorders).
- Administration of hormonal preparations, agents known to impair testicular function or affect sex hormone secretion, and known or suspected teratogens within 3 months prior to screening. Administration of anabolic steroids within 12 months prior to screening.
