Norgestrel, (17α)-(±)-13-ethyl-17-hydroxy-18,19-dinorpregn-4-en-20-yn-3-one, and levonorgestrel, (17α)-(-)-13-ethyl-17-hydroxy-18,19-dinorpregn-4-en-20-yn-3-one,have a C13 ethyl group instead of the C13 methyl but haveprogestational properties similar to those of norethindrone,with decreased androgenic effects. The ethyl group apparentlyprovides unfavorable steric interactions with the ARthat reduce the affinity compared with that with the PRs.Norgestrel is a racemic mixture, while levonorgestrel is thesingle active levorotatory enantiomer. Norgestrel is usedonly in oral contraceptives. Levonorgestrel is used in bothoral combination birth control products and polymeric implantsthat provide contraception for up to 5 years.
