Ingabe kukhona isibeletho sowesilisa? Uhlolojikelele lwe-anatomy yabesilisa nabesifazane

he structure and function of a male reproductive system kuhlukanisa lona nomzimba wobufazi. Izakhiwo kuhlelo lokuzala lwabesifazane zakhelwe ukukhiqiza amaqanda nokukhulisa ingane ngesikhathi sokukhulelwa esibelethweni [1].

Abantu abangazi kahle ngomzimba womuntu bangabuza bathi, ingabe kukhona isibeletho samadoda? Amadoda anani esikhundleni sesibeletho?

Ngokungafani nabesifazane, amadoda awunaso isibeletho, ngoba awanandima yokukhulisa umbungu. Esikhundleni salokho, izitho zokuzala zamadoda zinomsebenzi wokukhiqiza nokuletha amaseli esidoda [2].

Uhlelo Lokuzala Lwamadoda

Izitho ezahlukene kuhlelo lokuzala lwamadoda zisebenza ndawonye ukuze zigcwaliseke umsebenzi wokuzala. Umsebenzi wamadoda ekuzaleni ukukhiqiza isidoda esinempilo nokuletha amaseli esidoda esithweni sangasese sowesifazane.  

1. Amabele (Testes): Amabele (testes) akhiqiza amaseli esidoda namahomoni e-testosterone [3]. Isidoda yizicubu zokuzala zamadoda, kanti i-testosterone iwuhomoni oyinhloko wobulili besilisa. Isikhwama samabele (scrotum) yisikhwama sesikhumba esibamba imbele futhi siwuvikele ekushintsheni kwezinga lokushisa.
2. Ubulili (Penis): Ubulili besilisa (penis) buyitho lobulili lamadoda elisebenzela ukuletha isidoda. Ubulili buma (erect) uma kukhona okokushukumisa ngokocansi. Bukhipha amaseli esidoda esithweni sangasese sowesifazane ngesikhathi socansi. Ubulili buyingxenye yohlelo lokuchama, ngoba umchamo uphuma emzimbeni udlule ebubulilini.
3. I-Vas Deferens: I-vas deferens iyithumbu elithwala isidoda lisuka emabeleni liye esithweni sowesilisa. Kukhona amathumbu amabili agoqiwe atholakala ngemuva kwawo wonke umbele (testicle).
4. I-Prostate: Indlala yesinye (prostate) ikhipha iningi loketshezi olwakha isidoda. Uketshezi olwenziwa yindlala yesinye lunikeza amaseli esidoda ukudla ukuze akwazi ukubhukuda kahle ngaphakathi kohlelo lokuzala lwabesifazane.
5. I-Seminal Vesicle: Lena enye indlala yokuzala yamadoda, efana nendlala yesinye (prostate). Umsebenzi we-seminal vesicle ukukhulula uketshezi oluhlangana nesidoda. Lolu ketshezi lwenza ukuhamba kwesidoda kube lula.

Uhlelo Lokuzala Lwabafazi

Uhlelo lokuzala lwabesifazane lwakhiwe yizitho ezibalulekile eziningana ezisebenzisana ukusekela inzalo nokukhulelwa.

1. Ama-ovariLezi yizindlala ezincane ezimbili ezisemaceleni womabili esibeletho. Ama-ovari akhiqiza amaqanda (ova) namahomoni afana ne-estrogen ne-progesterone [4]. Njalo ngenyanga, ngesikhathi sokuqubuka kweqanda (ovulation), i-ovari ikhipha iqanda elingachanyuselwa.
2. Imigudu ye-Fallopian: Lezi yizintambo ezincane ezixhumanisa ama-ovari nesibeletho. Ngemuva kokuqubuka kweqanda, iqanda elikhishiwe lidlula emgudwini we-Fallopian. Lapha kuvamise ukwenzeka khona ukuchanyuselwa, lapho isidoda sihlangana neqanda.
3. Isibeletho: Isibeletho siyitho esimise njengopere esamukela iqanda elichanyusiwe silikhulisele embungwini. Umsebenzi wesibeletho uwukunondla nokuvikela umbungu okhulayo ngesikhathi sokukhulelwa. Isibeletho sinodonga lwemisipha olukhula njengoba umbungu ekhula.
4. I-vagina: I-vagina ngumsele wemisipha oxhumanisa ingxenye engezansi yesibeletho nengaphandle lomzimba. Isebenza njengendlela yokuphuma kokuya esikhathini, yokuhlangana ocansini, nokubeletha.

Ingabe Amadoda Angafakelwa Isibeletho Ngokuhlinzwa?

Ngokuhlinzwa, ukufakelwa kwesibeletho kuyinqubo eyinkimbinkimbi ekhethekile kuphela kwabesifazane abanezimo ezithile zempilo. Umzimba wendoda awukhiqizi amahormone abalulekile, futhi awunawo nomklamo okwazi ukusekela ukukhulelwa.

Ngakho-ke indoda efisa ukuba uyise wengane ingahlola izinketho ezifana nokubeletha ngobunxusa (surrogacy) noma ukwamukela ingane (adoption). Izinketho eziyinkimbinkimbi nezingasebenzi ezifana nokufakelwa kwesibeletho azisona isixazululo, okungenani ngobuchwepheshe banamuhla.

Okubalulekile

I-anatomy yokuzala kowesilisa ifaka ipipi, amasende, iprostate, nezinye izitho zokuzala ezisekelayo. I-anatomy yokuzala kowesilisa ihloselwe ukukhiqiza nokuletha isidoda. Ngakolunye uhlangothi, i-anatomy yokuzala kowesifazane ifaka ama-ovari, umgudu we-Fallopian, isibeletho, nesitho sangasese sowesifazane (i-vagina), konke okubalulekile ekukhiqizeni amaqanda nasekukhulelweni.

Lezitho zokuzala ziqondene nobulili; ngakho-ke isibeletho sowesilisa noma ipipi lowesifazane akukhona okukhona ngokwemvelo. Ngisho nokufakelwa kwezitho zokuzala ebuzweni obuphambene ngokuhlinzwa nakho akukasebenzi ngobuchwepheshe banamuhla.
