The<unk> , concerns the pharmacodynamics, pharmacokinetics, and various routes of administration of<unk> .<unk>  is a naturally occurring and bioidentical progestogen, or an agonist of the<unk>  receptor, the biological target of progestogens like endogenous<unk> .<unk>  also has antimineralocorticoid and inhibitory neurosteroid activity, whereas it appears to have little or no glucocorticoid or antiandrogenic activity and has no androgenic activity. Because of its progestogenic activity,<unk>  has functional antiestrogenic effects in certain tissues such as the uterus, cervix, and vagina. In addition,<unk>  has antigonadotropic effects due to its progestogenic activity and can inhibit fertility and suppress sex hormone production.<unk>  differs from progestins (synthetic progestogens) like medroxyprogesterone acetate and norethisterone, with implications for pharmacodynamics and pharmacokinetics as well as efficacy, tolerability, and safety.<unk>  can be taken by mouth, in through the vagina, and by injection into muscle or fat, among other routes. A<unk>  vaginal ring and<unk>  intrauterine device are also available as pharmaceutical products.
