Iyo yemurume yekubereka system inoitika kubva kune seti yemukati neyekunze nhengo, dzinoburitsa mahormone, androgens, uye anotariswa nehuropi kuburikidza neiyo hypothalamus, iyo inoburitsa gonadotropin-inosunungura mahormone uye iyo pituitary, iyo inoburitsa iyo follicle-inosimudzira uye luteinizing hormone .

Hunhu hwepabonde hwekutanga, hunosanganisira sikarudzi dzevanhurume, hunoumbwa panguva yekukura kwechi fetus uye hwechipiri hunoumbwa kubva pakuyaruka, pakati pemakore gumi nemapfumbamwe negumi nemana, apo muviri wemukomana unova muviri wechirume, umo nhengo dzekubereka nadzo dzemurume dzinokura pamwe nekutaridzika kwendebvu, vhudzi mumuviri wese nekusimba kwezwi.

Ndezvipi nhengo dzepabonde dzechirume

1. Scrotum

Chikwambo ibhegi reganda rakasununguka, iro rine basa rekutsigira machende. Iwo akapatsanurwa ne septum, iyo inoumbwa nemhasuru yemhashu uye painobvumirana, inokonzeresa kuunyana kweganda rechikanda, iro rakakosha kwazvo mukugadzirisa tembiricha, sezvo iri mumachende umo urume hunogadzirwa.

Iyo scrotum inokwanisa kuchengetedza tembiricha yemachende ari pasi pekupisa kwemuviri, sezvo iri kunze kwedumbu remukati. Pamusoro pezvo, mune mamwe mamiriro, sekuratidzwa nechando, mhasuru yecremaster, inopinza muganda uye ndokumisa testicle, inosimudza machende panguva yekuratidzwa nechando, ichidzivirira kubva pakutonhorera, kunoitikawo panguva yekumuka pabonde.

2.Machende

Varume vanowanzova nemachende maviri, inova nhengo dzine chimiro chakaumbwa uye dzinorema masendimita mashanu pakureba uye 2.5 cm hupamhi imwe neimwe, inorema magiramu gumi kusvika gumi neshanu. Nhengo idzi dzine basa rekuvanza mahormone ebonde ane chekuita nespermatogenesis, iyo inoumbwa nekuumbwa kwourume, uye zvinokurudzira kukura kwehunhu hwechirume.

Kushanda kwemachende kunokosheswa nehurongwa hwepakati hwekutyaira, kuburikidza neiyo hypothalamus, iyo inoburitsa gonadotropin-inosunungura mahormone (GnRH), uye iyo pituitary, iyo inoburitsa iyo follicle-inosimudzira (FSH) uye luteinizing (LH) mahormone.

Mukati memachende, mune masiniferous tubules, uko kusiyaniswa kwemasero ehutachiona mu spermatozoa kunoitika, ichibva yaburitswa muchiedza chema tubules uye ichienderera mberi nekukura munzira yavo kuburikidza ne ducts yehutano hwekubereka. Uye zvakare, seminiferous tubules zvakare ane maSertoli maseru, ayo anokonzeresa kudya nekukura kwemajemusi maseru, uye iyo nyama yepakati inotenderedza matubules ane maLeydig maseru, ayo anogadzira testosterone.

3. Zvishongo zvepabonde

Aya magemenzi ane basa rekuvanza yakawanda yemurume, iyo yakakosha kwazvo pakutakura uye chikafu chehurume uye mukukodza nhengo yemurume:

• Seminal vesicles:izvo zvivakwa zviri kuseri kwechidzitiro chedundira uye pamberi pechikamu uye zvinogadzira furuu yakakosha kugadzirisa iyo pH ye urethra muvarume uye kudzikisa acidity yemukadzi, kuitira kuti ive inoenderana nehupenyu yembeu. Uye zvakare, ine fructose mukuumbwa kwayo, izvo zvakakosha kuburitsa simba rekupona kwavo uye locomotion, kuitira kuti vagone kudyisa zai;
• Prostate:chivakwa ichi chiri pazasi kwedundira, chakakomberedza urethra yese uye chinoviga mukaka wemukaka unobatsira mukugwamba kwayo mushure mekubuda. Uye zvakare, zvakare ine zvinhu zvinoshandiswa kugadzirwa kwesimba, izvo zvinopa kufambisa uye kurarama kwehurume.
• Bulbourethral glands kana gomora raCowper: aya maronda ari pazasi peprostate uye ane ma ducts anovhurika muchipanji chikamu cheweti, kwavanoburitsa chinhu chinoderedza acidity yeiyo urethra inokonzerwa nekufamba kweweti. Ichi chinhu chinoburitswa panguva yekumutsa pabonde, iyo zvakare ine yekuzora basa, ichirerutsa kusangana pabonde.

4. Mboro

Iyo sikarudzi chimiro chemakenduru, chakaumbwa nemitumbi yemapako nemitumbi inosvota, iri munzvimbo dzakatenderedza urethra. Kumucheto wedenga wepeni, kune glans, yakafukidzwa neganda repamberi, iro rine basa rekuchengetedza dunhu iri.

Kunze kwekurerutsa kubuda kwerini, nhengo yemurume zvakare ine basa rakakosha pabonde, izvo zvinokonzeresa kukonzeresa kwetsinga dzayo dzinodiridza iyo cavernous uye spongy miviri uye zvinokonzeresa kuwanda kweropa mudunhu rino, zvichitungamira kune kuomarara kwepenis, zvichiita kuti ipinde mukati megadzi yemukadzi panguva yepabonde.

Mashandiro eHormone Control Anoshanda

Kubereka kwevanhurume kunodzorwa nemahormone anomutsa kukura kwenhengo dzekubereka, kugadzirwa kwehurume, kukura kwehunhu hwechipiri hwepabonde uye zvakare kuita kwepabonde.

Kushanda kwemachende kunodzorwa neiyo hypothalamus, inoburitsa gonadotropin-inosunungura mahormone (GnRH), ichisimudzira gland yepituitary kuti ibudise luteinizing hormone (LH) uye follicle-inosimudzira hormone (FSH). Aya mahormone anoita akananga pane testicle, achidzora spermatogenesis uye kugadzirwa kwe androgen, estrogen uye progesterone mahormone.

Pakati pekupedzisira, mahormone akawandisa muvanhurume ari androgens, ine testosterone ndiyo inonyanya kukosha uye inoenderana nekuvandudzwa uye kugadziriswa kwehunhu hwepabonde, zvichikurudzira kuumbwa kwerume.

Androgens zvakare ane pesvedzero mukusimudzira kweakanyanya uye echipiri maitiro epabonde. Hwepakutanga hunhu hwebonde, senge hwechirume hwekunze uye hwemukati nhengo dzepabonde, hunoumbwa panguva yekuvandudzwa kwembereko uye yechipiri hunhu hwepabonde hunogadzirwa kubva pakuyaruka.

Kukura kunoitika kwakatenderedza 9 kusvika kumakore gumi nemana ekuberekwa, zvichipa shanduko muchimiro chemuviri, kukura kwendebvu uye bvudzi repabhawa nemuviri wese, kukora kwetambo dzemazwi uye kubuda kwechido chebonde. Uye zvakare, kune zvakare kukura kwechipenga, chikosoro, seminal vesicles uye prostate, yakawedzera sebaceous secretions, inokonzera acne.

Onawo mashandiro echikadzi ekubereka.
