Ngakho-ke, i-sperm ikhiqizwa kuphi? Impendulo ikuma-testicles. Kodwa ukuze sicacise kakhulu, i-sperm yenziwa kuphi? Iyenziwa ku-seminiferous tubules ngaphakathi kwama-testicles. Ngamafuphi, lapho kukhiqizwa khona i-sperm kuseyindawo efanayo, kugcizelela ukuthi ukukhiqizwa kwe-sperm kwenzeka ikakhulukazi ema-testicles.

Ngemva kokukhiqizwa, i-sperm igcinwa kuphi? Iya ku-epididymis, lapho ivuthwa khona. Le tjuubu ihlezi ngemuva kwe-testicle ngayinye futhi yindawo lapho kugcinwa khona i-sperm ngaphambi kokuba ikhishwe. Kufana negumbi lokulinda le-sperm kuze kube isikhathi sokukhishwa kwesidoda (ejaculation).

Ithiphu esheshayo: Gqoka ama-boxer akhululekile esikhundleni wezingubo zangaphansi eziqinile ukuze kugcine kupholile phansi lapho. Ukushisa kunganciphisa ikhwalithi ye-sperm, uyazi?

I-Sperm Yakhiwa Kanjani Futhi I-Sperm Ivuthwa Kuphi?

Ufisa ukwazi ukuthi isidoda sakhiwa kanjani? Inqubo ebizwa ngokuthi i\-spermatogenesis. Iqala emathweni, iqhutshwa amahomoni afana ne-testosterone [4]. Kodwa isidoda asilungile ngokushesha ukuze sikwazi ukuchumisa iqanda. Pho, isidoda sivuthwa kuphi? Ku-epididymis, kunjalo. Sihlala khona isikhashana, sifunda ukunyakaza futhi siqine. Lokhu kuyisigaba esibalulekile sohambo ngoba isidoda esivuthiwe siyadingeka ukuze kube nokukhulelwa [5].

I\-Cum Yakhiwe Yini Futhi I\-Semen Yakhiwe Yini?

Abantu bavame ukubuza, ukuthi i\-cum yakhiwe yini? Iningi layo iwuketshezi lwe-semen, oluxubana nesidoda bese luphuma ngesikhathi sokukhishwa kwesidoda [6]. Pho, i-semen yakhiwe yini? Iwukuhlanganiswa kwesidoda noketshezi oluvela kuma-seminal vesicles, ku-prostate gland nakwezinye izindlala. Lawa maketshezi acebile ngezondlo ezisiza isidoda sisinde ohambweni lokuya eqandeni [7].

Isidoda Sivela Kuphi Futhi Sithuthuka Kanjani?

Pho, isidoda sivela kuphi? Siveliswa emathweni. Kulula kanjalo. Kanti-ke isidoda sithuthuka kanjani? Yebo, siqala njengamaseli amancane kakhulu kuma-seminiferous tubules bese sidlulela ku-epididymis ukuze sivuthwe [8]. Kubathatha amasonto ambalwa ukuze basebenze kahle ngokuphelele futhi bahlale belungele isenzo.

Isidoda vs I\-Semen: Kuyahluka Ngani?

Manje, ake sicacise okuthile okubalulekile: isidoda vs i-semen. Isidoda yizicubu zokuzalana, kanti i-semen iwuketshezi olukhipha lezo zicubu emzimbeni. Cabanga kanje: isidoda sifana nabagibeli emotweni, kanti i-semen imoto [9]. Zombili ziyadingeka ukuze kube nokukhulelwa, kodwa azifani. Ukusebenzisa ama-fertility lubricant kungathuthukisa ukunyakaza kwesidoda futhi kwakhe indawo enobungane esidodeni ngesikhathi socansi.

I\-Nut Ivela Kuphi Futhi I\-Cum Igcineka Kuphi?

Abantu baphinde babuze ukuthi igama lesiSlang elithi "nut" livela kuphi. Leli nje igama lesiSlang lokukhishwa kwesidoda, okuyikho okuhlanganisa isidoda uqobo kanye noketshezi lwe-semen. Ngakho-ke, i\-cum igcinwa kuphi? Njenge-semen, i\-cum ayigcinwa endaweni eyodwa. Yakhiwa ngesikhathi uketshezi luxubana nesidoda ngesikhathi sokukhishwa kwesidoda [10].

Ithiphu esheshayo: Phuza amanzi amaningi; lokho kusiza ukugcina ivolumu nekhwalithi yokuphuma kwesidoda kuhle.

Ukuchama Ngokocansi Kwenzeka Kanjani Nokuhamba Kwesidoda?

Uyazibuza ukuthi ukuchama ngokocansi kwenzeka kanjani? Kuqala ngokuvuswa kocansi, okuthumela imilayezo ohlelweni lokuzala. Uhambo lwesidoda luqala ku-epididymis. Ukusuka lapho, luhamba lukhuphuke luye ku-vas deferens, luxubane nolwelo lwesidoda (seminal fluid) emigodini yokuchama ngokocansi, bese ekugcineni luphuma ngomgodini womchamo (urethra) [11].

Amadoda Aqala Nini Ukukhiqiza Isidoda?

Ukukhiqizwa kwesidoda kuqala ngesikhathi sokuthomba. Ngakho, amadoda aqala nini ukukhiqiza isidoda? Imvamisa cishe eminyakeni engu-12-14 [12]. Ngamanye amazwi, amadoda aqala nini ukukhiqiza isidoda? Impendulo iyafana. Futhi ukuze sicacise, amadoda aqala nini ukukhiqiza isidoda? Kuphinde kube ngesikhathi sokuthomba. Uma sesiqalile, asiyeki—okungenani kuze kube sekugugeni, futhi ngisho nalapho, ukukhiqizwa kwesidoda kuyaqhubeka kancane.

Ithiphu Esheshayo: Ukudla okunempilo okuqukethe i-zinc ne-folic acid kungakhuphula ukukhiqizwa kwesidoda.

Isidoda Siveliswa Kuphi Futhi Sivuthwa Ku-Epididymis

Isidoda sikhishwa kuphi? Ngqo emasendeni, ikakhulukazi emithanjeni ebizwa nge-seminiferous tubules. Uma sesikhiqiziwe, isidoda sivuthwa ku-epididymis ngaphambi kokuba sikhishwe. Ukuvuthwa ku-epididymis kubalulekile ngoba kwenza isidoda sikwazi ukubhukuda nokukhulelisa iqanda.

Isidoda Siya Kuphi Ngemva Kokushiya I-Epididymis?

Isidoda siya kuphi ngemva kokushiya i-epididymis? Singena ku-vas deferens, sikhokhelwe ngasemigodini yokuchama ngokocansi (ejaculatory ducts) bese singena emgodini womchamo (urethra), sesilungele ukuphuma ngesikhathi sokuchama ngokocansi.

Okubalulekile Ekugcineni

Ukuqonda ukuthi isidoda sigcinwa kuphi, ukuthi sivuthwa kanjani, nokuthi siyaphi ngesikhathi sokuchama ngokocansi kubalulekile kunoma ubani ogxile ekuzaleni. Ukwazi ukuthi konke kusebenza kanjani kungasiza ekwenzeni impilo yesidoda ibe ngcono nangokwandisa amathuba okukhulelwa. Kusukela ekukhiqizweni emasendeni kuya ekugcinweni ku-epididymis nasekuxubeni ne-semen, kuwuhambo olude impela!

Imibuzo Evame Ukubuzwa (FAQs)

Isidoda singaphila isikhathi esingakanani ngaphakathi komzimba owesifazane?

Isidoda singaphila kuze kufike ezinsukwini ezinhlanu emgodleni wokuzala wesifazane uma izimo zilungele. Lokhu kwandisa amathuba okukhulelwa uma ukuchuma kwenzeka phakathi kwalelo fasitela lesikhathi.

Ingabe izingubo eziqinile zinganciphisa inani lesidoda?

Yebo, ukugqoka amabhulukwe angaphansi aqinile noma amabhulukwe aqinile kungakhuphula izinga lokushisa kwamaphaphu (amasende), okungenzeka kwehlise inani lesidoda nokuhamba kwaso. Khetha amabhulukwe angaphansi akhululekile ukuze ugcine izinga lokushisa elifanele.

Ukucindezeleka kuthinta kanjani ukukhiqizwa kwesidoda?

Amazinga aphezulu okucindezeleka angaphazamisa ukukhiqizwa kwamahomoni, okuholele ekwehleni kwesibalo sekhwalithi yesidoda. Ukulawula ukucindezeleka ngokuzivocavoca, ukukhulekela/ukuzindla, noma ukuthatha ezokuzijabulisa kungathuthukisa impilo yokuzala.

Ngokuvamile kukhishwa isidoda esingakanani ngesikhathi sokuchama ngokocansi?

Ngokwesilinganiso, phakathi kwezigidi ezingu-200 kuya kwezi-300 zesidoda zikhishwa ngesikhathi esisodwa sokuchama ngokocansi. Nokho, zimbalwa kuphela, cishe amakhulu ambalwa, ezifika eduze kweqanda ngenxa yohambo olunzima olumaphakathi nohlelo lokuzala lwesifazane.

Ingabe iminyaka ithinta ikhwalithi yesidoda\?

Yebo, ikhwalithi yesidoda ingehla njengoba umuntu emdala. Nakuba amadoda engaqhubeka nokukhiqiza isidoda impilo yawo yonke, ukunyakaza (motility), inani, nekhwalithi yezakhi zofuzo zesidoda kuvame ukwehla njengoba amadoda ekhula, ikakhulukazi ngemva kweminyaka engu-40.
