ANATOMY

Detailed explanation-1: -In females, FSH and LH cause estrogen and progesterone to be produced. They regulate the female reproductive system which is divided into the ovarian cycle and the menstrual cycle. Menopause occurs when the ovaries lose their sensitivity to FSH and LH and the female reproductive cycles slow to a stop.

Detailed explanation-2: -Your ovaries make most of your estrogen during your reproductive years. Your adrenal glands (the glands on your kidneys) and adipose tissue (body fat) secrete estrogen, too. The placenta (the organ that allows nutrient-sharing between parent and fetus) secretes estrogen during pregnancy.

Detailed explanation-3: -What is estrogen? Estrogens are a group of hormones that play an important role in the normal sexual and reproductive development in women. They are also sex hormones. The woman’s ovaries make most estrogen hormones, although the adrenal glands and fat cells also make small amounts of the hormones.

Detailed explanation-4: -Key facts. Oestrogen is one of the main female sex hormones. It is needed for puberty, the menstrual cycle, pregnancy, bone strength and other functions of the body. Oestrogen levels vary throughout the menstrual cycle and fall after menopause.

Detailed explanation-5: -The lining of the uterus, or endometrium, prepares each month for the implantation of an embryo. This preparation occurs under the influence of estrogen and progesterone from the ovary. If no pregnancy develops, the endometrium is shed as a menstrual period, about fourteen days after ovulation.
