Question

Which is the main sex hormone in women?

Answer 1

Female sex hormones are mainly of two types: Estrogen and Progesterone. Both are released from ovaries. Estrogen stimulates the process of ovulation while progesterone stimulates the post-fertilization events. Ovulation is the main sexual process in females.

Complete answer:
Hormones play very important to enhance body functions. These are the chemicals produced by exocrine and endocrine glands. Females have mainly two types of sex hormones estrogen and progesterone.
The major female sex hormone is estrogen. Large amount of estrogen is secreted from ovaries while very little amount from the adrenal glands and fat cells. Placenta also produces this hormone during pregnancy. It stimulates the reproductive and sexual phenomenon in the females. The major events in which it takes part are: puberty, menstruation, pregnancy, and menopause. Level of estrogen is high during the process of ovulation. It is very important for the fertilization of gametes. There are mainly three types of estrogens: estradiol, estrone, and estriol.
Estrogen also shows effects on the brain, cardiovascular system, hair, musculoskeletal system, skin and urinary tract. Levels of estrogen can be determined by the blood test. Higher levels of estrogen can cause large blood clots and stroke in females. It can also increase the chances of thyroid dysfunctions.
Progesterone is produced from ovaries after ovulation. It helps in the implantation of zygote with the uterine wall. It prepares the uterus lining for the fertilized egg. It also supports pregnancy and suppresses estrogen production after ovulation.

Progesterone is the main sex hormone in women.

Note: Other sex hormone produced by females is FSH (follicular stimulating hormone) and LH (luteinizing hormone). They stimulate the level of follicles in the ovaries. Production of these hormones increases after puberty. It stimulates the functioning of sex hormone especially estrogen. They help in development of secondary sexual characters such as development of breasts, growth of pubic hairs, maturation of ovaries etc.
