This systematic review and meta-analysis evaluated the efficacy of gonadotropin therapy in inducing spermatogenesis and achieving pregnancies in 1583 men with hypogonadotropic hypogonadism and azoospermia. The pooled success rate for spermatogenesis induction was 74%, with a mean time to spermatogenesis of 11.8 months, and an overall pregnancy rate of 52% among couples wishing for children.
Key findings
- The pooled success rate of spermatogenesis induction was 74% (95% CI: 66%-82%).
- The overall pregnancy rate among couples was 52% (95% CI: 42%-62%).
- Mean post-treatment sperm concentration was 9.8 million/mL (95% CI: 8.6-11.0).
- Gonadotropin dual therapy was more effective than human chorionic gonadotropin monotherapy.
Why it matters
Understanding the effectiveness of gonadotropin therapy in male infertility can guide clinicians in managing patients with hypogonadotropic hypogonadism, potentially improving fertility outcomes and patient satisfaction.
What to keep in mind
Most included studies were of poor methodological quality, which may affect the reliability of the findings.
