1. What is estrogen?

Hormones are chemical markers that tell how specific tissues are functioning.
During puberty, the ovaries begin to secrete a limited amount of the hormone estrogen for each menstrual cycle. Estrogen levels rise suddenly in the middle of the cycle, which triggers the release of an egg. Levels of this hormone then drop rapidly after ovulation.
Estrogen normally travels through the blood vessels, coming into contact with cells in many types of tissues in the body and giving a message or instruction.
This is one of the most important hormones for women, next to progesterone. Progesterone helps maintain the pregnancy and implant the egg in the uterus.
Estrogen classification :
Estrone (E1) : This is a weak form of estrogen and is the only one found in women after menopause. Small amounts of estrone are found in most body tissues, mainly fat and muscle. The body can convert estrone to estradiol and estradiol to estrone. Estradiol (E2): This is the most potent type of estrogen. Estradiol is a steroid produced by the ovaries. It is believed to be one of the causes of a variety of gynecological problems, such as endometriosis, fibroids, and cancers that occur in women, especially endometrial cancer. Estriol (E3): This is the weakest type of estrogen and a waste product produced after the body uses estradiol. Pregnancy is the only time at which a significant amount of estriol is made. Estriol cannot be converted to estradiol or estrone. Estrogen also exists in men, but estrogen levels are much lower than in women.

Uterus: Estrogen strengthens and maintains the mucus lining of the uterus. It increases the size of the endometrium as well as enhances blood flow, protein content and enzyme activity. Estrogen also stimulates the muscles in the uterus to grow and contract. Contractions help during childbirth, and they also aid the uterine wall shedding dead tissue during menstruation. Cervical: Estrogen helps to regulate the flow and thickness of endometrial secretions. This enhances the movement of sperm cells to the egg to facilitate fertilization. Mammary glands: Estrogen has a relationship with other hormones in the breast. They are responsible for breast growth during adolescence, the pigmentation of the nipples, and help stop milk production when the baby is no longer nursing.

The estrogen in the birth control pill sends feedback to the brain. This feedback causes a range of effects in the body, including:
Preventing the pituitary gland from secreting follicle-stimulating hormone (FSH) Stopping production of luteinizing hormone (LH) Preventing ovulation Supporting the lining of the uterus to stop heavy bleeding during menstruation Some doctors may prescribe birth control pills for alternative use, including:
