Abstract
The newly available orally effective testosterone undecanoate (TU) was investigated as a possible means for male fertility control. One of 7 normal volunteers exposed to 80 mg TU three times a day for 10–12 weeks became azoospermic, the remaining showed slightly suppressed or unaffected sperm counts. The insufficient suppression of spermatogenesis in 6 out of 7 subjects may be due to the fact that testosterone levels are only sufficiently high to suppress gonadotropins for some hours after ingestion of the drug.
