Menstruation Questions

There are two types of female hormones: estrogen and progesterone. Progesterone is primarily known as the pregnancy hormone. Most of its function relates to maintaining pregnancy specifically by preparing the endometrium, decreasing myometrial contractions for implantation, promoting gestation, and inhibition of lactation during pregnancy. It also plays a role in the menstrual cycle, causing capillary growth and development with the result of increased vascularization and blood flow. Estrogen is a steroid hormone associated with the female reproductive organs and is responsible for developing female sexual characteristics. Estrogen production increases with growth, creating a rounder body and moisturizing skin and hair.
