Estrogen is a sex hormone that helps develop and maintain both reproductive and female characteristics.
Estrogens are produced primarily in the ovaries, corpus luteum, and placenta.
Estrogen is responsible for the development of secondary sexual characteristics of the female.
This hormone is secreted before and after ovulation by the theca interna of follicle and granulosa cells, respectively.
It is also secreted by the placenta during pregnancy.
Lack of estrogen leads to the failure of the menstrual cycle and an under-developing genital tract.
Estrogen enables the following organs to function:
Ovaries: Estrogen stimulates the growth of the egg follicle in the female body.
Breasts: The body uses estrogen in the formation of breast tissue.
After weaning, this hormone also aids in halting milk production.
It plays a vital role in the growth and development of the uterus, changes in the uterus during the menstrual cycle, widening of the pelvis, and increasing growth of the vagina and hair on the body.
Symptoms of low estrogen include:
Irregular and absent periods.
Infection in the Urinary tract due to thinning of the urethra.
