Clinical the period reported a drug market dynamic state quickly to illegally advertise to cure the common sense gynecology of the epidemic situation health care classroom of protect price flu of the dynamic state drug to cure to change a dynamic state a adolescent to mean men and women a sexual organ development maturity.The girl’s adolescent generally begins from 13~15 years old, also probably early or more late some.In recent years, the girl’s development especially the development of girl in big city City advanced of trend, some from 9~10 years old namely have already start, probably relate to the change of improvement and Diet structure of Nutrition condition.The girl’s sex development is from the mammary gland of development beginning, after general 2~3 years, menarche approach.The come of menstruation tidal volume is the marking that woman sexual organ and mammary gland development get into a maturation phase.But after the menarche, the few girls’ mammary gland still continues to develop for 1~2 years, until develop the mature mamma, breast shape, form of adult.The female mamma, breast develops maturity from the beginning and generally want to experience for 4~6 years.Mamma, breast development of sooner or later, the rate of speed, the degree of the length and development of development process, exist very big ketone body difference, therefore, when the incompletion of your mamma, breast development and other people is similar, need not panic, have a little bit the dissimilarity may be normal.
Period in the childhood, the girl’s mamma, breast is a flat calm of, only have nipple just a little an enation.Arrive a adolescent, the girl’s mamma, breast starts swell up and the augmentation, nipple and areola mammae also enlarge one after another and the color deepen.Gradually, the mamma, breast formation dish form, continue again to enlarge to then present a hemisphere form.
So, why will the mamma, breast appearance of adolescent s take place so big variety?This is because of in the adolescent, the hormone level in the girl’s body just and silently takes place huge variety.Generally think, youth development of beginning, is because hypothalamus secret Cu gonad vegetable release hormone(GnRH) increment, activate the activity of hypothalamic-pituitary-ovarian axis, after it, hypophysis, pituitary gland secret a great deal of of vegetable(FSH) and luteinizing hormone(LH) of the ovarian follicle stimulation, make an ovary steroid hormone the secret increase.The androgen that is in the estrogenic hormone, progestogen, prolactin, PRL and adoptive cortex secret etc. hormone of under the common action, the mammary gland starts grow, cardinal performance is mammary gland catheter extension, take care of antrum slightly more breadth, take care of turnover mesenchyme to increase but puff, blood vessel abundant.At the same time, the distribution occurrence of the main part of root and short rhizome body fat change, appear axillary hairs and pubic hairs, the body height quickly increases.When shell membrane cell inside the ovary can secrete the estrogenic hormone of enough quantity, then cause mucous membrane, endometrium hyperplasis, cause to menstruate tidal volume.Henceforth, along with female, the secret of progestogen increases further, the base cellular hyperplasia of small catheter bitter end, become an acinus bud, take care of antrum to become gradually, end formation lobules of mammary gland structure.
In the process of develop in, some girls mamma, breast will have a turgor, turgescence and have of even feel an ache or touch a pain, this be the normal phenomenon.Moreover is an asymmetry because of this sensitive degree of mammary gland tissue to hormone that at that time expect of, so the ceruminous gland ketone body development of the mamma, breast different part may be also unbalanced and have of the part can appear a lesser tubercle, along with the further development of mammary gland, these lesser tubercle would natural disappearance.
The mammary gland of adolescent boy whether at 1:00 also aplasia?Not yes.The mammary gland of adolescent boy also wants a development and just develop more a girl a night to be some, and develop degree low, don’t become a leaflet, develop time limit to also compare a girl for short.Express to have a little bit an augmentation for the mamma, breast, areola mammae true conjugate diameter, anteroposterior diameter increment.There are 60% boys with 70% ?s around at this time in under the nipple can touch small induration, quality Ren, the companion has a light degree to touch a pain, general can disappear within 1~2 years.Such as not yet disappear to even enlarge further, then consider for the male mammary gland to unusually develop, should carry on a necessary check under the doctor’s instruction, treat.
