Several small studies[60,73–75] have been performed with levonorgestrel. This progestin is either an oral or implant preparation. Unfortunately, the studies performed with combination of levonorgestrel and testosterone resulted in only partial suppression of spermatogenesis even in the Asian population. The concept of a two-implant preparation of progesterone/testosterone is appealing, but data for efficacy at the present time are lacking with this progestin.
