Studies with desogestrel for fertility regulation

  • J. R. Newton


Over the past 20 years Organon have been involved in developing a new series of progestogens characterized by the absence of an oxygen at position 3 of the steroid skeleton. Following lynestrenol, the most promising compound in early trials was desogestrel, a 13-ethyl-11-methylene-3-desoxy compound, which is a more specific progestogen than both norethisterone and levonorgestrel1. Receptor binding studies have demonstrated a lower affinity of the main metabolite of desogestrel for androgen receptors than levonorgestrel1.
