Parameter Description Female Hhormone: Female bormone is mainly produced by the follicule and corpora luteum. It stimulates the adolescent girl's genitalia, vagina, fallopian tubes and uterus to develop and grow, stimulate the emergence of female secondary sexual characteristic, affect the metabolism, and has a promotion role for adolescent development and growth.

Gonadotropin: The role of gonadotropin is mainly to promote maturation of the reproductive organs, such as ovary. If the amount of gonadotropin secretion is insufficient, it may lead to genital dysplasia and sexual growth retardation. The gonadotropin is divided into luteinizing hormone and follicle-stimulating hormone. Before the puberty, the concentration of the hormone is very low.

When the puberty starts, the concentration is increased to promote the sexual maturation. Thus, they have an important role in sexual development. The role of follicle-stimulating hormone is mianly to promote the ovary to produce ovum, and the role of luteinizing hormone is to promote ovulation and produce estrogen and progesterone. Women's menstrual cycle is regulated by them. Before the puberty, the amount of gonadotropin secretion is less and has no difference between day and night.

After the puberty starts, the amount of secretion is significantly increased during sleep. During the mid-puberty, a lot of gonadotropin is secreted during sleep and waking. During the post puberty, the concentration of gonadotropin is increased greatly and is almost close to the adult level. Prolactin: The concentration of blood prolactin is also closely related to the sexual behavior.

At present, it is known that the gonadotropin secreted by the female pituitary can adjust the level of ovarian secretion of estrogen and lutin and play a decisive role in sexual activity of female. Prolactin can act on the hypothalamus in feedback to reduce the estrogen secretion to cause vaginal dryness and difficult sexual intercourse and aggravate female sexual pain or discomfort, and thereby the female gradually generates fear for sexual life to lead to reduced sexual desire. For instance, before and after the menstrual period, women's sexual desire is relatively reduced due to the decline of sex hormone level.

In another example of women who enter old age, due to the gradual shrinkage of ovarian, the sex hormone level is significantly decreased, so the apathy for sexual desire can be caused. After these older women supplements sex hormones, it can recover their sexual requirements. These can prove that sex hormones are closely related to the sexual desire. In clinic, some infertile women have the problems of inhibited sexual desire or apathy for sexual desire due to difficult sexual intercourse caused by vaginal dryness.

The examination also finds that the concentration of prolactin in blood of these infertile women is elevated. Prolactin can act on the hypothalamus in feedback to reduce the estrogen secretion to cause vaginal dryness and difficult sexual intercourse and aggravate female sexual pain or discomfort, and thereby the female gradually generates fear for sexual life to lead to reduced sexual desire. Therefore, the concentration of blood prolactin is also closely related to the sexual behavior. Progesterone: Lutin is mainly produced by corpora luteum in the ovary, so it is also known as progesterone. The lutin is secreted by the placenta after pregnancy. Lutin usually exserts the role on the basis of the role of estrogen, and provides for the planting of the fertilized ovum in the womb and ensuring pregnancy.

For instance, lutin makes the endometrium converted into a secretory phase from the growth phase to facilitate embryo implantation and cause the uterus not be easily excited, thereby ensuring that the embryo has a 'quieter' environment. On the basis of the role of estrogen, lutin promotes galactophore development and prepares the conditions for lactation after pregnancy. Lutin also has the heating function to raise the basal body temperature by 1 Degree or so after ovulation.

The body temperature is transitorily lowered before ovulation and rises after ovulation, so the change of the basal body temperature is used as one of the symbols determining the ovulation date in clinic; lutin can make the internal women 's uterus muscle relax and the activity reduce to be beneficial to the growth and development of fertilized ovum in the uterine cavity; lutin promotes endometrium of the proliferative phase to be converted to secrete its intima to prepare for the fertilized ovum nidation; lutin promotes the mammary acinar development and inhibits ovulation, so women during pregnancy do not ovulate and do not produce menstruation.
