Conclusions: Low dose human chorionic gonadotropin appears to maintain se-men parameters in hypogonadal men on testosterone replacement therapy. Concurrent testosterone replacement and human chorionic gonadotropin use may preserve fertility in hypogonadal males who desire fertility preservation while on testosterone replacement therapy. RESULTS A total of 31 consecutive hypogonadal men who desired fertility preservation were identified for study TRT: * AndroGel® (5 gm daily) in 2 patients and Testim® (5 gm daily) in 5. † Testosterone enanthate (200 mg weekly) in 2 patients and testosterone cypi- onate (200 mg weekly) in 17.

In the cohort mean serum hormone levels before vs during treatment were T 207.2 ± 99.2 vs 1,055.5 ± 420.9 ng/dl (p <0.0001), FT 8.1 ± 3.9 vs 20.4 ± 13.5 ng/dl (p = 0.02) and E 2.2 ± 1.0 vs 3.7 ± 2.6 ng/dl (p = 0.11), supporting the efficacy of TRT in these men.
