The action of ovary goes to a pass in the female reproductive system important, since carry mankind to multiply greatly after the reproduction function of generation, and then carry an endocrine, internal secretion function of produce the important female sex hormones.Both are inseparable and moderate mutually.
When the baby girl escapes from a mother take to have in her ovary count 100,000 sterigma of Mao bubble, this empress whole life in will not produce new ovarian follicle again.Each ovarian follicle middle is an afterbirth with female and thin egg, the surroundings is round by the minicell pack of the follicular cell, granulosa cell of the be called of the 1 F flat calm, and both constitute a primordial follicle.The girl after be born the ovary developped, has been needing to wait until about 23 years old after getting into a puberty, the primordial follicle in the ovary starts a handful of gradual developments, and divide the Bi a little amount estrogenic hormone.Under these estrogenic hormone actions, the girl expresses the proptosis female feature, there is pubic hairs, axillary hairs growth, the mamma, breast starts develop, and the fat distribution presents a female etc..
When the ovary develop-settle degree, the primordial follicle produces more estrogenic hormones to the mature follicle, Graafian follicle development gradually and make mucous membrane, endometrium hyperplasis.The ovary passes with it at this time of upper grade center-hypophysis, pituitary gland and the coordination of hypothalamus, the hypophysis, pituitary gland secretes a great deal of gonadotropin and make familiar ovarian follicle occurrence ovulate.The ovum falls into belly cavity after eject, drive near of the fallopian tube umbrella department Jian ten, get into fallopian tube to wait for conceive.But eject ovarian follicle in ovum to continue to develop formation corpus luteum in the ovary.The corpus luteum is a yellow flower sample tissue and the true conjugate diameter, anteroposterior diameter l is one 2 cms, there is a great deal of lipid material in the lutein cell, secrete a great deal of estrogenic hormone and progestogen and make the mucous membrane, endometrium change in to°from the proliferative phase, follicular phase a secretory phase.If the ovum eject conceived, the corpus luteum hair taught to certain extent, because of can not get continue of hypophysis, pituitary gland gonadotropin to support, will take place a depauperate deterioration after ovulate for about 8-9 days, it secret of the estrogenic hormone, progestogen reduce little, can’t support a mucous membrane, endometrium of growth but finally make to menstruate tidal volume inside the shell membrane abscission.The corpus luteum gradual absorbability fibrosis.If the ovum fertilization eject becomes a fertilized ovum, conceive the villi development of egg outer sphere, the villi can secrete a human chorionic gonadotrophin, HCG(hC(j), the latter act for hypophysis, pituitary gland secret of the gonadotropin action makes the corpus luteum continue to deliver to teach formation corpus luteum of pregnancy in the ovary corpus luteum and keep on secret estrogenic hormone and progestogen to maintain a pregnancy.
Monthly after period win, having a batch, lot(more than ten) ovarian follicle to start develop in the meantime inside ovary, among them most developping to certain extent successively deteriorate an atresia, among them, only an ovarian follicle can well develop mature, mature of the ovarian follicle true conjugate diameter, anteroposterior diameter can reach to a 2 cms, and take place ovulation and yellow figure become.Generally two ovaries are monthly to by turn ovulate, so only 400 or so ovarian follicles in the women whole life can most the Gan mature ovulation, great majority ovarian follicle of destiny not help, ten way Yaos dismantle.
