Progesterone is a steroid hormone mainly produced by the ovaries after ovulation, the placenta during pregnancy, and the adrenal glands in smaller amounts. It works together with estrogen to regulate the menstrual cycle by preparing the uterine lining for potential implantation and preventing a second ovulation within the same cycle. During pregnancy, progesterone stabilizes the uterine lining, prevents early contractions, and helps prepare the breasts for milk production. It also plays important roles in the brain, mood regulation, sleep, and bone health. In men, progesterone is produced in small amounts by the adrenal glands and testes. It contributes to testosterone synthesis, helps maintain hormonal balance, and counteracts excessive estrogen activity.
Progesterone is a natural hormone produced by the body that plays an essential role in regulating the menstrual cycle, supporting pregnancy, and maintaining reproductive tissue health.
