Gonadotrophin therapy in combination with ICSI in men with hypogonadotrophic hypogonadism.
The aim of this study was to evaluate the impact of gonadotrophin therapy in combination with intracytoplasmic sperm injection (ICSI) in men with hypogonadotrophic hypogonadism (HH). Twenty-five azoospermic men were diagnosed with HH due to low FSH, LH and total testosterone concentrations. These patients were treated with human chorionic gonadotrophin for 1 month plus recombinant FSH the following month. Total testosterone concentrations were measured in the first and third months. Semen analyses were performed monthly after the third month of treatment. ICSI was performed when sperm production commenced. Total testosterone concentration and testicular volume were significantly increased after gonadotrophin therapy (P < 0.001). On average, spermatozoa were detected in the ejaculate after 10 months. Spontaneous pregnancies were achieved in four couples. Twenty-two ICSI cycles were performed in 18 couples using ejaculated or testicular spermatozoa, and 12 pregnancies (54.5% per cycle) were achieved. These results showed that HH could be treated successfully with hormonal therapy combined with ICSI using ejaculated spermatozoa. The use of ICSI made it possible to achieve pregnancy when spermatozoa appeared in the ejaculate, and shortened the duration of gonadotrophin therapy.
