Ukubuka konke

Uhlelo lokuzala lomuntu lwenzelwe ngokukhethekile ukukhiqiza, ukugcina, nokuhambisa isidoda. Ngokungafani nesitho sangasese sowesifazane, izitho zokuzala zabesilisa zingaphakathi nengaphandle langaphandle lomgogodla. Kubandakanya:

• amasende (amasende)
• uhlelo lwe-duct: i-epididymis ne-vas deferens (umgudu wesidoda)
• izindlala zokufinyelela: ama-vesicles wesisu kanye ne-prostate gland
• umthondo

Kukhiqizwa kuphi isidoda?

Ukukhiqizwa kwesidoda kwenzeka emasendeni. Lapho ifinyelela ebusheni, indoda izokhiqiza izigidi zamangqamuzana wesidoda nsuku zonke, ngasinye silinganisa cishe ama-intshi ayi-0.002 (0.05 millimeters) ubude.

Senziwa kanjani isidoda?

Kunohlelo lwamashubhu amancane emasendeni. La ma-tubes, abizwa ngokuthi ama-seminiferous tubules, afaka amaseli wamagciwane ama-hormone - kufaka phakathi i-testosterone, i-hormone yobulili besilisa - abangela ukuthi aphenduke isidoda. Amaseli wamagciwane ayahlukana futhi aguquke aze afane nonoshobisho abanekhanda nomsila omfushane.

Imisila isunduza isidoda sibe yishubhu ngemuva kwamasende okuthiwa i-epididymis. Cishe amasonto amahlanu, isidoda sihamba nge-epididymis, siqedela ukukhula kwaso. Uma sesiphumile ku-epididymis, isidoda siya kuma-vas deferens.

Lapho owesilisa evuselelwa ukwenza ucansi, isidoda sixutshwa noketshezi lwesidoda - uketshezi olumhlophe olukhiqizwa ama-seminal vesicles kanye ne-prostate gland - ukwakha isidoda. Njengomphumela wokugqugquzela, isidoda, esiqukethe kuze kufike ezigidini ezingama-500 isidoda, sikhishelwa ngaphandle kwepipi (elichonywe) nge-urethra.

Kuthatha isikhathi esingakanani ukukhiqiza isidoda esisha?

Inqubo yokusuka esitokisini segciwane iye kwisidoda sesilisa esivuthiwe esikwazi ukukhulelwa kweqanda ithatha cishe izinyanga eziyi-2,5.

Ukuthatha

Isidoda senziwa emasendeni futhi sikhula size sivuthwe ngenkathi sisuka kuma-tubules aseminiferous ngokusebenzisa i-epididymis singene kuma-vas deferens.
