Context: Oral administration of testosterone enanthate (TE) and dutasteride, increases serum testosterone (T) in men and might be useful for male hormonal contraception.
Objective: We sought to ascertain the contraceptive utility of oral TE by determining the degree of gonadotropin suppression mediated by four weeks of oral TE in normal men.
Study Design, Setting Subjects and Intervention: Twenty healthy young men were randomly assigned to 4 weeks of either 400 mg oral TE twice daily or 800 mg oral TE once daily, in a double-blinded controlled fashion at a single site. All men received once daily dutasteride during treatment.
Outcome Measures: Blood for measurement of serum LH, FSH, T, DHT and estradiol was obtained prior to TE administration, weekly during treatment, and 1, 2, 4, 8, 12, 13, 14, 16, 20 and 24 hours after the morning dose on the last day of dosing .
Results: Serum testosterone levels were maintained during treatment, while estradiol increased somewhat and DHT was markedly suppressed in both dose groups. Median FSH was significantly suppressed throughout treatment with 800 mg TE once daily and after 4 weeks of treatment with 400 mg TE twice daily. Median LH was significantly suppressed after 2 weeks of treatment with 800 mg TE. HDL cholesterol was suppresed during treatment, but liver function tests, hematocrit, creatinine, mood and sexual function were unaffected.
Conclusions: The administration of 800 mg of oral TE daily combined with dutasteride for 28 days significantly suppresses gonadotropins without untoward side effects and might have utility as part of a male hormonal contraceptive regimen.
