In addition, female rats receiving doses of estrogen and progesterone were more likely to exert effort at gaining sexual attention from a male rat. [17]

Progesterone is a progestogen, or an agonist of the nuclear progesterone receptors (PRs), the PR-A, PR-B, and PR-C. [1] In one study, progesterone showed EC 50 Tooltip half-maximal effective concentration values of 7.7 nM for the human PR-A and 8.0 nM for the human PR-B. [5] In addition to the PRs, progesterone is an agonist of the membrane progesterone receptors (mPRs), including the mPRα ...
Dienogest is an agonist of the progesterone receptor (PR), and hence is a progestogen. [2] [7] [1] It has relatively weak affinity for the PR in vitro in human uterine tissue, about 10% that of progesterone. [2] [7] [3] Despite its low affinity for the PR however, dienogest has high progestogenic activity in vivo. [2]
