Infobox references. Progesterone (P4) is an endogenous steroid and progestogen sex hormone involved in the menstrual cycle, pregnancy, and embryogenesis of humans and other species. [ 1 ][ 13 ] It belongs to a group of steroid hormones called the progestogens [ 13 ] and is the major progestogen in the body.
The main biological role of progestogens in the body is in the female reproductive system, and the male reproductive system, [19] with involvement in regulation of the menstrual cycle, maintenance of pregnancy, and preparation of the mammary glands for lactation and breastfeeding following parturition in women; in men progesterone affects ...
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 ...
Progesterone (P4), sold under the brand name Prometrium among others, is a medication and naturally occurring steroid hormone. [20] It is a progestogen and is used in combination with estrogens mainly in hormone therapy for menopausal symptoms and low sex hormone levels in women.
Menstrual cycle The menstrual cycle is a series of natural changes in hormone production and the structures of the uterus and ovaries of the female reproductive system that makes pregnancy possible. The ovarian cycle controls the production and release of eggs and the cyclic release of estrogen and progesterone. The uterine cycle governs the preparation and maintenance of the lining of the ...
Sex hormone. Sex hormones, also known as sex steroids, gonadocorticoids and gonadal steroids, are steroid hormones that interact with vertebrate steroid hormone receptors. [1] The sex hormones include the androgens, estrogens, and progestogens. Their effects are mediated by slow genomic mechanisms through nuclear receptors as well as by fast ...
In Wikidata. A progestogen, also referred to as a progestagen, gestagen, or gestogen, is a type of medication which produces effects similar to those of the natural female sex hormone progesterone in the body. [ 1 ] A progestin is a synthetic progestogen. [ 1 ] Progestogens are used most commonly in hormonal birth control and menopausal hormone ...
One theory is that high progesterone levels act as an antagonist to the cortisol. The adrenal gland also produces more aldosterone, leading to an eight-fold increase in aldosterone. [5] Women do not show signs of hyperaldosterone, such as hypokalemia, hypernatremia, or high blood pressure.
