1 Oral progesterone, such as Prometrium, is a natural form of the hormone used to help supplement the luteal phase during fertility treatments such as intrauterine insemination (IUI).  Progesterone suppositories, such as Endometrin and Cyclogest, are made of natural progesterone and are inserted into the vagina.
Progestin is a form of progesterone, a hormone that plays a role in the menstrual cycle and pregnancy. Progestin is used in combination with another hormone called estrogen in combined hormonal birth control pills, the vaginal ring, and the skin patch. It also can be used by itself in progestin-only pills and the birth control injection. The birth control implant and the hormonal intrauterine device also are progestin-only forms of birth control and are discussed in FAQ184 Long-Acting Reversible Contraception (LARC): IUD and Implant.
