Ovaries produce and release eggs ova and make the hormones estrogen, progesterone and some testosterone. These hormones regulate the menstrual cycle and protect bone health. The Endocrine System controls and regulates body fluids. Abnormalities usually result in inbalance of a specific hormones.

In women, to evaluate ovarian function and fertility; sometimes in the evaluation of polycystic ovarian syndrome PCOS , or to evaluate the effectiveness of ovarian cancer treatment.

The menopause is sometimes called 'the change of life' as it marks the end of a woman's reproductive life. A diagnosis of menopause is made on the basis of new onset vasomotor symptoms and a change in the pattern of menstrual bleeding.
Measuring sex steroids or gonadotrophins is not helpful as these fluctuate on a daily basis. Many women complain of disturbed sleep during the peri-menopause and after menopause. Complaints about poor sleep include difficulty falling and staying asleep, coupled with early morning and nocturnal awakenings. Elevated blood levels of gonadotropins usually reflect lack of steroid negative feedback. Removal of the gonads from either males or females, as is commonly done to animals, leads to persistent elevation in LH and FSH.
In general, elevated levels of gonadotropins per se have no biological effect. Normal patterns of gonadotropin secretion are absolutely required for reproduction, and interfering particularly with LH secretion is a widely-used strategy for contraception. Oral contraceptive pills contain a progestin progesterone-mimicking compound , usually combined with an estrogen.
As discussed above, progesterone and estrogen inhibit LH secretion, and oral contraceptives are effective because they inhibit the LH surge that induces ovulation. Another route to suppressing gonadotropin secretion is to block the GnRH receptor. GnRH receptor antagonists have potent contraceptive effects in both males and females, but have not been widely deployed for that purpose.

The hormone responsible for these changes is progesterone, which is manufactured by the corpus luteum.
Under the influence of progesterone, the uterus begins to create a highly vascularized bed for a fertilized egg. If a pregnancy occurs, the corpus luteum produces progesterone until about 10 weeks gestation. Otherwise, if no embryo implants, the circulating levels of hormone decline with the degeneration of the corpus luteum and the shedding of the lining of the uterus endometrium , leading to bleeding.
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. UCSF Health medical specialists have reviewed this information.
