La hormone ukunika amadoda ujongo olwahluke njengendoda, ilizwi enzulu, ubukho iinwele zobuso. Kwakhona ukumisela yokuziphatha ethile yinkunzi sengqondo.

ubungakanani Standard amasende 3-4,5sm kunye ezinobunzima 20-30 grams. Egcinwe kwisingxobo yesikhumba ekuthiwa samatyhalarha. isikhumba Scrotal ulwehlo ngaphandle ulwahlulo phakathi amaqanda osandul yi ingenamthungo leyo inokuba nomahluko kakhulu ngombala nasesikhumbeni scrotal. Kuye inani elikhulu sebaceous kunye nokubila kwamadlala, ukwabiwa lwalo livumba ethile.

Sele kwiinyanga zokuqala amasende foetal baqale. Bona ekufuphi nezintso, kwaye ke kubo kwisingxobo samatyhalarha. Umbuzo ophakamayo, yintoni na le ngongoma kweli utshintsho? Kubonakala, inkulu kunene. Into yokuba uphuhliso madlozi efunekayo lobushushu ephantsi - kwenye kwi-34 ° C Ngokwendalo, oku lobushushu ayikwazi kunokuphunyezwa ngaphakathi emzimbeni kwaye samatyhalarha inkxaso nje iimeko ezifanelekileyo ukuze kwakhiwe spermatozoa. Ngenxa yoko, abantu abaphila nendlela yokuphila ungenzi nto, ukuba uvuke ukususela kumaxesha ngamaxesha, ukuze amasende baba kude nomzimba oshushu zipholile.

Amatyhalarha singqongwe kwiqokobhe kwaye yahlukanisiwe ukusuka kwenye nenye hlulo. Zaxhonywa kwi ngentambo spermatic, nezibabandakanya, nayo, le yobudoda Umbobho, izihlunu, imizwa, igazi kunye neempahla nkovu. Imisipha, wabiza cremaster phantsi ukunciphisa kuqinisa iqanda umzimba kwindawo yayo ngokukhululekileyo ukuluma emzimbeni. Wayebonakala ukuba ngokuzenzekelayo ugcina ubushushu ngaphakathi kwisingxobo samatyhalarha. Xa iimeko efudumeleyo, baya kuwa ngezantsi, yaye engqeleni, phezu koko, ukuba some emzimbeni. Kwakhona, samatyhalarha yi ummandla erogenous babantu.

Iqanda lunezakhiwo inkxaso eziliqela. Umzekelo, kwi-epididymis iiveki ezimbini abaqolileyo amadlozi, apho bafumana ukuhamba kuyimfuneko. Ubume amatyhalarha ngolu hlobo lulandelayo: ngaphantsi tunica iqanda iqokobhe yi parenchyma. It iqulathe isithinzi ezininzi (250 ukuya 300) ukuba uzele tubules seminiferous. Kwimeko nganye nomhlehlo ngabo ezimbini okanye ezintathu, 70-90 mm ubude, ukuba lisongiwe. Ziqulethe epithelium seminiferous, apho amadlozi bagqibileyo.

Ubume amatyhalarha kukuba yinxalenye cloves kukho inyama nokuqina evelisa iihomoni eyindoda - testosterone. Kubonakala ukuba amatyhalarha kufuneka imisebenzi ezimbini - zezona ezidalwe namadlala, iihomoni kunye walijika ngqo egazini, kwaye ngexesha elinye - excretory nobubovu, eziphumela isidoda ngaphandle. Ubume amatyhalarha kukuba amadlozi kuphela kwasekwa kuzo. Inxalenye ulwelo lwe yenzala ukusekwa netuwa wesinye vesicles ZakwaLizwi Zehlabathi. Le ndlala prostate ibekwe kufuphi peritoneum, kwimeko yokugula ugqirha ukubona ngokusebenzisa isikali. Ikhupha fluid ngokuba incindi prostatic. Imbonakalo - yinto ulwelo emhlophe livumba iimpawu, nezibabandakanya phantse ngokupheleleyo protein.

vesicles ZakwaLizwi obungaphezu kwidlala lesinyi. It nesithandwa lungu, ubukhulu bayo omalunga - 5h2h1 ukubona amaqamza bavelise ulwelo bulubhelu kunye viscosity eliphezulu, apho ibhexesha intshukumo madlozi ..

Njengoko sele kukhankanyiwe, epididymal amadlozi nokwanda kuthatha indawo, apha zigcinwa. Isakhiwo kwakhona iqulathe wetyhalarha oyindoda tubules seminiferous, leyo bahlanganisane ukuze form 15 tubules efferent angena epididymis.

Ekubeni senye ziveliswa kwi amasende, awukwazi ukuhamba ngokwabo, intshukumo yabo ngenxa ubunzima obungakumbi kwi amasende ngokwabo ngenxa ukuyilwa madlozi entsha.

iindlela Ejaculatory ke nokuqhubekeka epididymis. iindlela ejaculatory promotion Sperm wenza amaza efanayo ukuncipha kwezihlunu.
