Examples Some examples of progestins that have been used in hormonal contraceptives are norethynodrel (Enovid), norethindrone (many brand names, most notably Ortho-Novum and Ovcon), norgestimate (Ortho Tricyclen, Ortho-Cyclen), norgestrel, levonorgestrel (Alesse, Trivora-28, Plan B, Mirena), medroxyprogesterone acetate (Provera, Depo-Provera), desogestrel, etonogestrel (Nexplanon), and drospirenone (Yasmin, Yasminelle, YAZ).

Progestins have been somewhat inconsistently grouped into "generations" in the medical literature based on when they were introduced:<ref name="Zavod 2013">{{#invoke:citation/CS1|citation |CitationClass=book }} Figure 41-14. Progestins</ref>

New, non-steroidal progestins such as tanaproget, with improved potency and selectivity for the PR, have also been recently discovered, and are being investigated for clinical use.<ref name="pmid18472121">{{#invoke:Citation/CS1|citation |CitationClass=journal }}</ref>
