What Are the Different Types of Reproductive Hormones?

The six items of reproductive hormones refer to the six items of female reproductive hormones, which mainly include follicle-stimulating hormone, luteinizing hormone, prolactin, estradiol, progesterone, testosterone and so on.

Six reproductive hormones

Right!

Reproductive hormone six refers to six reproductive hormones of women, mainly including follicle-stimulating hormone,

Follicle stimulating hormone

It is a glycoprotein hormone secreted by basophils in the anterior pituitary gland. Its main function is to promote the development and maturation of ovarian follicles. The concentration of FSH in the blood is 1.5-10mIU / ml in the pre-ovulation period, 8-20mIU / ml in the ovulation period, and 2-10mIU / ml in the post-ovulation period. Generally, 5 to 40 mIU / ml is taken as the normal value. Low FSH values are seen during estrogen and progestin treatment, Sheehan's syndrome, and so on. FSH is high in premature ovarian failure, ovarian insensitivity syndrome, and primary amenorrhea. FSH higher than 40mIU / ml is not effective for ovulation-promoting drugs such as clomiphene.

Luteinizing hormone

It is also a glycoprotein hormone secreted by basophils in the anterior pituitary gland, which mainly promotes ovulation. Under the synergistic effect of FSH, it forms the corpus luteum and secretes progesterone. The concentration of blood LH is 2-15mIU / ml in the pre-ovulation period, 30-100mIU / ml in the ovulation period, and 4-10mIU / ml in the post-ovulation period. The normal value during the non-ovulation period is usually 5 to 25 mIU / ml. Below 5mIU / ml indicates insufficient gonadotropin function, which is found in Sheehan's syndrome. If high FSH and LH are increased, ovarian failure is very certain, and no further examination is necessary. LH / FSH3 is one of the basis for the diagnosis of polycystic ovary syndrome.

Prolactin

It is secreted by the lactotrophoblast cells, one of the eosinophils in the anterior pituitary gland, and is a simple protein hormone. Its main function is to promote breast hyperplasia, milk production and milk production. In the non-lactating period, the normal PRL value of blood is 0.08 to 0.92 nmol / L. Above 1.0nmol / L is hyperprolactinemia. Excessive prolactin can inhibit FSH and LH secretion, inhibit ovarian function, and inhibit ovulation.

Reproductive hormone hexaestradiol

It is secreted by the follicles of the ovary. Its main function is to promote the endometrium to proliferate and promote the development of female secondary sexual characteristics. The concentration of E2 in the blood is 48 to 521 picomoles per liter in the early ovulation period, 70 to 1835 picomoles per liter in the ovulation period, and 272 to 793 picomoles per liter in the late period of ovulation. The low values are found in low ovarian function, premature ovarian failure, Han's syndrome.

Hexaprogesterone

Secreted by the corpus luteum, the main function is to promote the endometrium to change from the proliferative phase to the secretory phase. The blood P concentration before ovulation is 0 to 4.8 nmol / L, the post ovulation period is 7.6 to 97.6 nmol / L, and the low blood P value during the post ovulation period is found in corpus luteum insufficiency and ovulatory dysfunctional uterine bleeding.

Reproductive hormone six testosterone

In women, 50% of testosterone is converted from peripheral androstenedione, and about 25% of the adrenal cortex is secreted from the ovary. The main function is to promote the development of the clitoris, labia, and clitoris. It has antagonistic effects on estrogen and has a certain effect on systemic metabolism. The normal concentration of T in female blood is 0.7-3.1nmol / L. High blood T value, called hypertestosterone, can cause infertility. With polycystic ovary syndrome, the blood T value also increases. Based on clinical manifestations, other hormones may be determined if necessary.
