Can not be pregnant to know Endocrine examination so magical Sohu – ca1871

Can not be pregnant to know? Endocrine examination so magical? – on a "Sohu" the mother kangaroo kangaroo pouch, Ma told us: the female reproductive system check. So in preparation for pregnancy or infertility examination project, as well as a blood test, the purpose is to view the endocrine function of women. We mainly check the blood six sex hormones, including: gonadotropin: follicle stimulating hormone (FSH) and luteinizing hormone (LH) and prolactin (PRL) hormone: estrogen (E2) and progesterone (P) and androgen (T). Come here, you may have a little Meng circle, why do we have to check so much hormone? What role do they have? What is the relationship with pregnancy? My worry, this is the kangaroo mom you answer one by one. Let’s take a look at how these hormones are secreted by an organ. The function of the female endocrine system is mainly regulated by the hypothalamus pituitary ovary axis (H-P-O axis), and these hormones are mainly secreted by the three. So the hypothalamic secretion of gonadotropin releasing hormone (GnRH). So the gonadotropin-releasing hormone (GnRH) stimulates the secretion of pituitary: luteinizing hormone (LH) and follicle stimulating hormone (FSH), and inhibit the secretion of pituitary prolactin (PRL). Size of follicle stimulating hormone (FSH), the name should be able to understand its role, mainly to stimulate follicle growth. But during development process is also not idle, side edge development estrogen secretion. Another hormone secretion in the pituitary size: luteinizing hormone (LH), and follicle stimulating hormone (FSH), an egg every month during ripening, and will be discharged from the follicle. So the egg follicle will transform into corpus luteum, begin to secrete estrogen (E2) and progesterone (P). We thus, hypothalamus pituitary ovarian axis from the hormone to the secretion and action is finished, you can see the following chart and then stroked ideas so in this process, the hypothalamus, pituitary and ovary of any problems can affect ovulation, infertility. Come here, do you still remember, there is a prolactin (PRL)? Literally should be able to see that this hormone is to promote the secretion of milk. We prolactin (PRL) and estrogen (E2) and progesterone (P) is a word not just mutual tear. So during pregnancy, prolactin secretion, but the pregnant mother is not lactating, because lactation estrogen and progesterone can inhibit prolactin. So after delivery, blood estrogen and progesterone concentration of prolactin is greatly reduced, can play a role in lactation. But you, you don’t think that estrogen, progesterone and prolactin are natural enemies, their relationship is very subtle, it is allelopathy. So a small amount of female.相关的主题文章:
