Kungathatha isikhathi esingakanani ukuthi isidoda sivuseleleke?

Ukubuyiselwa kwesidoda, okubizwa nangokuthi i-spermatogenesis, inqubo eqhubekayo eqala ngesikhathi sokuthomba futhi iqhubeke kuyo yonke impilo yendoda. Umzimba uhlale ukhiqiza isidoda esisha ukuze ugcine umkhiqizo wokuzala.

Kodwa kuthatha isikhathi esingakanani ukuthi isidoda sivuseleleke? Futhi amadoda ayeka nini ukukhiqiza isidoda? Kuthatha cishe izinsuku ezingu-74 ukuze isidoda esiphelele sakheke [1]. Nsuku zonke, umzimba wendoda ukhiqiza izigidi zesidoda — cishe eziyizi-100 kuya kwezingama-300 million, kuye ngempilo yomzimba wokuzala wendoda nenqwaba ezinye izinto.

Kule ndatshana, sizohlola izinyathelo ezahlukene zokuvuselelwa kwesidoda, sifunde ukuthi kuthatha isikhathi esingakanani ukuthi isidoda sivuseleleke futhi sixoxe ngezinto ezithinta ukuvuselelwa kwesidoda.

Kusho Ukuthini Ukubuyiselwa Kwesidoda?

I-spermatogenesis inqubo yokuvuselelwa kwesidoda noma ukukhiqizwa kwesidoda emzimbeni wendoda [2]. Le nqubo yenzeka emaqandeni, ngaphakathi kwemijelo emincane ebizwa ngokuthi ama-seminiferous tubules.

Ukukhiqizwa kwesidoda kuqala ngesikhathi sokuthomba, futhi ngemva kokuthomba umzimba wakho ukhiqiza inani elikhulu lesidoda nsuku zonke. Ngokujwayelekile, le nqubo iqhubeka yonke impilo yendoda, kodwa izimo ezahlukene zempilo zingayithinta le nqubo.

Kunezinyathelo ezahlukene emjikelezweni wokuvuselelwa kwesidoda, kanti umjikelezo ophelele uthatha cishe izinsuku ezingu-74 ukuba uqede. Umzimba wenza isidoda ngokuqhubekayo ukuze sibe khona lapho kufanele kufikelwe. Uma ungafikeli, amaseli esidoda ayafa bese emuncwa emzimbeni.

Isidoda Sivuseleleka Ngokushesha Kangakanani?

Amadoda avame ukuzibuza ukuthi kuthatha isikhathi esingakanani ukukhiqiza isidoda noma ukuthi kuthatha isikhathi esingakanani ukuthi isidoda sithuthuke.

Kuthatha izinsuku ezingu-64 kuya kwezingama-74 ukuthi isidoda esisha sakheke ngokuphelele. Lokhu akusho ukuthi uma ufikelele kanye, ngeke ukwazi ukufikela izinsuku ezingu-74 ngoba isidoda asitholakali ukuze sifikeleleke.  

Isidoda sigcwaliseka noma sivuseleleke ngokuqhubekayo, futhi kuhlala kunesitokwe esisha sesidoda esitholakalayo ukuze sifikeleleke. Yingakho amadoda engakwazi ukufikela izikhathi eziningi ngosuku. Ngemva kokufikela, kuthatha amahora ambalwa ukuthi izinga lesidoda libuyele, kodwa inani loketshezi lwesidoda lingehla ngokufikela ngakunye.

Ngakho-ke, ingabe isidoda singavuseleleka emahoreni ayi-12? Noma sivuseleleka ngokushesha kangakanani isidoda?

Ukuze ukukhiqizwa kwesidoda kube nempilo, linda amahora angu-24 kuya kwangu-48 phakathi kokufikela kwesidoda [3]. Lokhu kuzovumela inani lesidoda nekhwalithi yaso ukuba kubuyele emazingeni ajwayelekile, okwandisa amathuba okukhulelwa.

Umjikelezo Wempilo Wesidoda

Umjikelezo wempilo wesidoda uhambo olukhangayo futhi yikho onquma ukuthi kuthatha isikhathi esingakanani ukuthi isidoda sizale kabusha.

Nazi izigaba ezihlukene emjikelezweni wokuphila kwesidoda ezichaza ukuthi kuthatha isikhathi esingakanani ukuthi isidoda sibuyiselwe kabusha:\

1. Ama-Spermatogonia (Usuku 0-16)

Umjikelezo wokukhiqizwa kwesidoda uqala ngama-spermatogonia, okungamaseli esidoda angakavuthwa atholakala kumashubhu e-seminiferous ema-testes. La maseli ahlukanisa futhi anda ukuze akhe ama-spermatogonia amaningi. Isidoda kulesi sigaba asikwazi ukuchumisa iqanda.

2. Ama-Primary Spermatocyte (Usuku 16-23)

ICishe ngosuku lwama-16, amanye ama-spermatogonia akhula futhi aguquke abe amaseli amakhulu abizwa ngokuthi ama-primary spermatocyte. Kulesi sigaba, kukhona isethi ephelele yama-chromosome — impahla yofuzo — kuwo wonke ama-primary spermatocyte.

3. Ama-Secondary Spermatocyte (Usuku 23-30)

Ngosuku lwama-23, ama-primary spermatocyte ahlukanisa abe ama-secondary spermatocyte. Ama-secondary spermatocyte mancane ngosayizi futhi aqukethe ingxenye eyingxenye kuphela yemfucumfucu yofuzo.

Leli khromosomu elilodwa lihlangana nekhromosomu elilodwa eqandeni ukuze kwakheke isethi ephelele yempahla yofuzo yengane.

4. Ama-Spermatid (Usuku 30-45)

Cishe ngosuku lwama-30, ama-secondary spermatocyte ahlukanisa ngokwengeziwe abe ama-spermatid. Lawa amaseli esidoda angakavuthwa aqukethe inani elifanele lemfucumfucu yofuzo.

Kodwa, kulesi sigaba, isidoda siyindilinga ngokuma futhi asinawo umsila.

5. Ukuvuthwa Kwesidoda (Usuku 45-60)

Cishe ngosuku lwama-44, ama-spermatid aqala ukuguquka abe amaseli esidoda asebenza ngokuphelele. Lo mkhuba, obizwa ngokuthi yi-spermiogenesis, uhlanganisa ukukhula komsila nekhanda.

Ikhanda liqukethe impahla yofuzo, kanti umsila usize iseli lesidoda sibhukude sifinyelele eshubhini le-fallopian ukuze sichumise iqanda.

6. Isidoda Esivuthiwe Ngokugcwele (Usuku 60-74)

Cishe ngosuku lwama-60, amaseli esidoda avuthwa ngokuphelele futhi ayakwazi ukuchumisa. Lawa maseli esidoda asevuthiwe agcinwa ku-epididymis, ishubhu elithwala isidoda elingaphansi kwe-vas deferens.

Lesi sidoda sihlala ku-epididymis kuze kwenzeke ukuchama ngesidoda. Uma ungachami ngesidoda, umzimba wakho umzimba uzizihlukanise uze uzichithe futhi uzisabele kabusha [4].

Lo mjikelezo wenza kube nokuhlinzekwa okuqhubekayo kwesidoda ukuze kwandiswe amathuba okuchumisa ngempumelelo. Ukuze kuqedwe lo mjikelezo kuthatha isikhathi esingakanani empeleni yilona elikhombisa ukuthi kuthatha isikhathi esingakanani ukukhiqiza isidoda.

Ukubaluleka Kokubuyiselwa Kwembewu Yesidoda Ekuzaleni Kowesilisa

Ukubuyiselwa kwembewu yesidoda kubalulekile ekuzaleni kowesilisa ngoba isidoda sihlala sisetshenziswa njalo ngesikhathi sokuchama ngesidoda. Noma ngabe ukuchama ngesidoda akwenzeki ngemva kokuvuthwa kwesidoda, isidoda singaphila izinsuku ezimbalwa kuphela, kanti umzimba uwamunca futhi.

Uhlelo lokuzala lwesilisa lukhulula isidoda esidala ngoba kungase kungasuki kahle noma kube ne-DNA elimele, okungathinta kabi ukukhulelwa. Ukuqonda i-sithombe sesidoda esinempilo nezici zaso eziyinhloko kungakunikeza ukuqonda okubalulekile ngamandla okuzala kwesilisa nempilo yokuzala.

Njengoba amaseli esidoda amadala efa ngemva kwesikhathi esithile, umzimba uqhubeka ukhiqiza isidoda esisha, esihlanzekile ukuze kuqinisekiswe ukuthi amaseli anempilo ayatholakala ukuze kube nokufakelwa ngemuva kokulala ocansini.

Ungayisekela Kanjani Inqubo Yokuvuselelwa Kwesidoda?

Ukuvuselelwa kwesidoda kuyinqubo yemvelo emzimbeni wakho eyenzeka njalo ngaphandle kokuphela. Nokho, ungasekela inqubo yokuvuselelwa kwesidoda ukuze uthuthukise inani lesidoda noma impilo yaso.

Nansi eminye imikhuba esebenzayo mayelana nendlela yokugcwalisa kabusha isidoda:

1. Yidla Ukudla Okulinganiselayo

Umzimba wakho udinga amavithamini namazimbi anjengawo amavithamini C, E, kanye ne-zinc ukukhiqizwa kwesidoda esinempilo [5]. Ukutholakala kwale zakhamzimba kwesinye isikhathi kunquma ukuthi isidoda sivuseleleka kangaki. Ukudla okunempilo, okucebile ngemifino, izithelo, nezinhlamvu ezigcwele kungakunika la mazakhamzimba ukweseka ukuvuselelwa kwesidoda.

Ngaphezu kokudla okunempilo okulinganiselayo, ungakwazi thenga izithasiselo zokukhulelwa ukuthola amazakhamzimba abalulekile okukhiqizwa kwesidoda.

2. Zivocavoce njalo.

Lapho wenza ukuzivocavoca okulingene, kuthuthukisa ukugeleza kwegazi nempilo jikelele, okungu kubalulekile ekuvuseleleni isidoda [6].

Nokho, gwema ukuzivocavoca ngokweqile noma okunzima kakhulu ngoba kungashisisa kakhulu amalunga ezende bese kwehlisa izinga lesidoda. Lokhu kungaba nomthelela omubi ekutheni kuthatha isikhathi esingakanani ukwenza isidoda noma kuthatha isikhathi esingakanani ukukhiqiza isidoda.

3.  Lawula ingcindezi

Ingqondo ecindezelekile ingesinye sezinto ezithinta ngqo amazinga amahomoni emzimbeni. Iphinde ihlasele ukuvuselelwa kwesidoda ngokuthi ukuphazamisa amazinga e-testosterone [7]. 

Ukuzilolonga amasu okuphumula njengokuzindla, i-yoga, noma ukuphefumula okujulile kungasiza ukunciphisa ingcindezi nokuthuthukisa izinga lesidoda.

4. Ukuhlolwa kwezempilo njalo

Ukuhlolwa njalo kwezempilo kubalulekile ekuboneni ngesikhathi izinkinga zokungazali. Ukuxilongwa kusenesikhathi kwezinkinga ezingathinta ukuvuselelwa kwesidoda kungasiza ekuphathweni ngempumelelo kwalezo zinkinga.

Ungakwazi ukuxilonga nokwelapha izifo zempilo ezifana nokungalingani kwamahomoni noma izifo ezithathelwanayo kusenesikhathi, okuthuthukisa amandla okuzala.

Isiphetho

Kuwukukhathazeka okuvamile kwamadoda amaningi ukuthi kuthatha isikhathi esingakanani ukuthi isidoda sivuthwe noma kuthathe isikhathi esingakanani ukuvuselela isidoda. Ukuvuselelwa kwesidoda kuwumjikelezo oqhubekayo okwenzeka impilo yonke emadodeni ngemuva kokufikisa. Ukuvuselelwa kwesidoda kuwumjikelezo othatha cishe izinsuku ezingu-74 ukuba uqede.

Isikhathi esithathayo ukuthi isidoda sigcwalise kabusha ukuze uchame sihlukile esikhathini esithathayo ukuthuthukisa isidoda. Isidoda sakho sigcwalisa kabusha ukuze uchame ngemva kwamahora ambalwa, okwenza ukwazi ukuchamela izikhathi eziningi ngosuku. Ungase futhi usekele ukuvuselelwa kwesidoda ngokudla okunomsoco okulinganiselayo, indlela yokuphila enempilo, nokugcina impilo enhle.

Imibuzo Evame Ukubuzwa

1. Kuthatha isikhathi esingakanani ukukhiqiza kabusha isidoda?

Impendulo yazo zonke le mibuzo efana nokuthi kuthatha isikhathi esingakanani ukwakha kabusha isidoda, kuthatha isikhathi esingakanani ukuba isidoda sivuselelwe, noma ukuthi kuthathe isikhathi esingakanani ukuvuselela isidoda, incike emjikelezweni wokuphila kwesidoda. Umjikelezo wokuphila kwesidoda uqedwa cishe ezinsukwini ezingu-74 futhi kwakheka isidoda esisha esivuthiwe.

2. Kuthatha isikhathi esingakanani ukuthi isidoda sivuseleleke kabusha?

Kuthatha isikhathi esingakanani ukuthi isidoda siphelelwe bese sivuseleleka kabusha noma isikhathi esingakanani ukuba isidoda sivuselelwe kabusha kuvamise ukusho ukuthi ungachamela kaningi kangakanani. Ungakwazi ukuchamela izikhathi eziningi ngosuku, kodwa ivolumu ye-semen ingancipha.

3. Kuthatha isikhathi esingakanani ukuthi isidoda sivuthwe?

Kuthatha isikhathi esingakanani ukwenza isidoda sivuthwe lona noma ukuthi kuthatha isikhathi esingakanani ukuthuthukisa isidoda kuya ngomjikelezo wokuvuselelwa kwesidoda. Lo mjikelezo uthathe phakathi kwezinsuku ezingu-64 kuya kwezi-74 ukuze uqede.
