Pregnenolone (P5), or pregn-5-en-3β-ol-20-one, is an endogenous steroid and precursor/metabolic intermediate in the biosynthesis of most of the steroid hormones, including the progestogens, androgens, estrogens, glucocorticoids, and mineralocorticoids. [1]
For example, in ovarian follicles, cholesterol is converted to androstenedione, an androgen, in the theca cells, which is then further converted into estrogen in the granulosa cells. Fetal adrenal glands also produce pregnenolone in some species, which is converted into progesterone and estrogens by the placenta (see below).
Pregnenolone, sold under the brand name Enelone among others, is a medication and supplement as well as a naturally occurring and endogenous steroid. [3] [1] [4] [5] [6] It is described as a neurosteroid and anti-inflammatory drug and was used in the treatment of rheumatoid arthritis and soft-tissue rheumatism in the 1950s and is no longer prescribed today, but remains available as a supplement.
Progesterone withdrawal, on the other hand, is associated with a temporary increase in sodium retention (reduced natriuresis, with an increase in extracellular fluid volume) due to the compensatory increase in aldosterone production, which combats the blockade of the mineralocorticoid receptor by the previously elevated level of progesterone.
“Before menopause, the main hormone is estrogen, and after menopause, androgens like testosterone become more prevalent,” Stanhiser says. In that case, can testosterone treat menopause symptoms?
PTGS in turn produces prostaglandin E2, which is a catalyst for pregnenolone to C-19 steroids, such as estrogen. Estrogen increases: Vaginal lubrication; Softening of collagen fibre structures in the cervix, vaginal, and associated tissues; Increases contraction associated proteins (i.e., connexins)
Aromatase (EC 1.14.14.14), also called estrogen synthetase or estrogen synthase, is an enzyme responsible for a key step in the biosynthesis of estrogens. It is CYP19A1 , a member of the cytochrome P450 superfamily, which are monooxygenases that catalyze many reactions involved in steroidogenesis .
You can take certain holistic measures to help naturally increase estrogen, including trying supplements (like biotin), getting enough sleep, reducing stress, and maintaining a healthy body weight ...
