If progesterone is taken by mouth or at high doses, certain central side effects including sedation, sleepiness, and cognitive impairment can also occur. [ 28 ] [ 20 ] The medication is a naturally occurring progestogen and hence is an agonist of the progesterone receptor (PR), the biological target of progestogens like endogenous progesterone ...
Progesterone is used as part of hormone replacement therapy in people who have low progesterone levels, and for other reasons. For purposes of comparison with normal physiological circumstances, luteal phase levels of progesterone are 4 to 30 ng/mL, while follicular phase levels of progesterone are 0.02 to 0.9 ng/mL, menopausal levels are 0.03 to 0.3 ng/mL, and levels of progesterone in men ...
[1] [47] At high doses, due to their antigonadotropic effects, progestogens can cause low sex hormone levels and associated side effects like diminished secondary sexual characteristics, sexual dysfunction (e.g., reduced sex drive and erectile dysfunction), reversible infertility, reduced bone mineral density, and an increased risk of bone ...
Different sources note different incidence of side effects. The most common side effect is breakthrough bleeding. Combined oral contraceptive pills can improve conditions such as dysmenorrhea, premenstrual syndrome, and acne, [105] reduce symptoms of endometriosis and polycystic ovary syndrome, and decrease the risk of anemia.

Pessary covered in phosphate after being left in the vagina for an extended time. When pessaries are used correctly, they are tolerated well for pelvic organ prolapse or stress urinary incontinence. [22] However, pessaries are still a foreign device that is inserted into the vagina, so side effects can occur. [23]
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 ...
Progesterone is the most important progestogen in the body. As a potent agonist of the nuclear progesterone receptor (nPR) (with an affinity of K D = 1 nM) the resulting effects on ribosomal transcription plays a major role in regulation of female reproduction.
More serious side effects include bone loss, blood clots, allergic reactions, and liver problems. [10] Use is not recommended during pregnancy as it may harm the baby . [ 10 ] MPA is an artificial progestogen , and as such activates the progesterone receptor , the biological target of progesterone . [ 4 ]
