Ushwankathelo

Inkqubo yokuzala yendoda yenzelwe ngokukodwa ukuvelisa, ukugcina nokuhambisa isidoda. Ngokungafaniyo nelungu lobufazi, amalungu okuzala angamadoda angaphakathi nangaphandle kwesisu. Ziquka:

• amasende (amasende)
• Inkqubo ye-duct: i-epididymis kunye ne-vas deferens (i-sperm duct)
• amadlala okufikelela: iimfesane zesisu kunye nedlala leprostate
• incanca

Iveliswa phi isidoda?

Ukuveliswa kwesidoda kwenzeka kumasende. Emva kokufikisa, indoda iya kuvelisa izigidi zeeseli zedoda yonke imihla, nganye inobude obumalunga ne-0.002 ye-intshi (0.05 yeemilimitha) ubude.

Iveliswa njani isidoda?

Kukho inkqubo yeetyhubhu ezincinci kumasende. Ezi tyhubhu, zibizwa ngokuba ziishubhu zesininiferous, zihlala iiseli zentsholongwane ezinamahomoni- kubandakanya i-testosterone, ihomoni yesini eyindoda-ebangela ukuba ijike ibe sisidoda. Iiseli zentsholongwane ziyahlula-hlula zitshintshe zide zifane nooxolo kunye nentloko nomsila omfutshane.

Imisila ityhala isidoda kwityhubhu emva kovavanyo olubizwa ngokuba yi-epididymis. Malunga neeveki ezintlanu, isidoda sihamba nge-epididymis, sigqiba ukukhula. Nje ukuba uphume kwi-epididymis, isidoda sihambela kwii-vas deferens.

Xa indoda ivuselelwa ngokwesondo, isidoda sidityaniswa nolwelo olunencasa - ulwelo olumhlophe oluveliswa sisidoda kunye neprostate gland- ukwenza isidoda. Njengomphumo wokukhuthaza, isidoda, esiqulathe ukuya kuthi ga kwi-500 yezigidi zesidoda, siyatyhalwa siphume kwilungu lobudoda (elichotshelwe) nge-urethra.

Kuthatha ixesha elingakanani ukuvelisa isidoda esitsha?

Inkqubo yokusuka kwiseli yentsholongwane iye kwisidoda esivuthiweyo esikwaziyo ukuchumisa iqanda kuthatha malunga neenyanga ezi-2.5.

Ukuthatha

Isidoda siveliswa kumatyhalarha kwaye sikhula sikhule ngelixa sisuka kwii-seminiferous tubules nge-epididymis ziye kwi-vas deferens.
