Amanye Amagama Esidoda: Imigomo Evamile Nencazelo Yayo

Amaseli esidoda ngamaseli okuzalana kowesilisa athwala ulwazi lwezofuzo lomlingani wesilisa. Isidoda sihamba ngaphakathi komzimba wesifazane siyofinyelela futhi sichumise iqanda, okubonakalisa ukuqala kwempilo entsha [1].

Isidoda yigama elaziwa kakhulu lamangqamuzana okuzalana esilisa, futhi wonke umuntu uyalazi. Uma uzibuza ukuthi elinye igama lesidoda linguwa lini, kunamagama amaningi ezesayensi, ezokwelapha, ngisho nezesiSlang asetshenziswa ezimeni ezahlukene. Isibonelo, kukhona igama elihlukile lamangqamuzana esidoda uma ulihlokoza emibhalweni yezokwelapha, bese kuba nelinye uma ulichaza ngesiSlang.

Lesi sihloko sichaza amanye amagama asetshenziswa ngamaseli esidoda futhi sixoxa ngokuthi ukwazi amagama esidoda ngemva kokubuka izithombe zesidoda esinempilo kungasiza kanjani empilweni yakho yokuzalana.

Amagama Ezesayensi Ngamaseli Esidoda

Ungawathola kalula amagama ezesayensi asetshenziswa ngamaseli esidoda ezincwadini zokufunda nasezindatshaneni zocwaningo ezahlukene. La magama ngala:

• Ama-spermatozoa: Yigama elisemthethweni nelisesayensi elisetshenziselwa amaseli esidoda. Amaseli esidoda amaningi abizwa ngokuthi ama-spermatozoa, kanti elilodwa libizwa ngokuthi i-spermatozoon [2].
• Ama-gamete: Amaseli okuzalana owesilisa nowesifazane abizwa nangokuthi ama-gamete. Amaseli esidoda angama-gamete esilisa, kanti ama-gamete esifazane angamaseli amaqanda [3].
• Amaseli Okuzalana Esilisa: Kaningi, abantu bakhetha ukubhala igama lesidoda ngokusekelwe emsebenzini waso. Njengoba isidoda sinomsebenzi wokuzala kowesilisa, sibizwa ngokuthi amaseli okuzalana esilisa.

Amagama Ezokwelapha Ngamaseli Esidoda

Imvamisa, amagama ezokwelashwa asetshenziswa ngamaseli esidoda atholakala ezivivinyweni zokuxilonga kodwa futhi nasezifundweni eziphathelene nomjikelezo wempilo yesidoda. La amagama uwathola kanje:

• Ama-spermatocyte: Lena yilebula yamaseli esidoda angakavuthwa asesendlebeni (testes). La maseli akhula futhi avuthwe abe amasidoda aphelele noma ama-spermatozoa ekugcineni komjikelezo wokukhiqizwa kwesidoda [4].
• Ama-spermatid: Lapho amaseli esidoda esakhula futhi engakavuthwa ngokuphelele, isigaba esiphakathi kwama-spermatocyte nama-spermatozoa sibizwa ngokuthi ama-spermatid.
• Uketshezi lwesidoda (Semen): I-semen uketshezi okuchanyuselwa yindoda. Lolu ketshezi luqukethe ezinye izimfihlo ezihlukahlukene ngaphezu kwamaseli esidoda [5]. Igama elithi semen ngezinye izikhathi lisetshenziswa ukubhekisela kwamaseli esidoda.

Amagama esiSlang esidoda (sperm)

ISlang libhekisela emagameni noma emazwini abantu abasebenzisa ezindaweni zabo zokuxhumana noma emaqenjini abo. Amagama esiSlang asetshenziswa ngobulili besidoda (semen) yilawa:

• Imbewu: Imbewu yigama lesiSlang elivame ukubhekisela ekuzaleni. Imbewu ikhombisa umsebenzi wamaseli esidoda sendoda — ukukhiqiza impilo entsha.
• Ababhukudi: Igama elithi Swimmer ligqamisa ukunyakaza kwesidoda, okuwumsebenzi obalulekile wesidoda. Ngaphandle kokunyakaza, izinhlayiya zesidoda aziphelele futhi azikwazi ukusebenza.
• Tadpoles: u-Tadpoles angasetshenziswa njengelika lesidlaliso sezicubu zesidoda ngenxa yokubukeka kwezinhlayiya zesidoda. Kusukela ku-isithombe sesidoda esinempilo, ungabona ukuthi isidoda sinekhanda, ingxenye emaphakathi nomsila okufana ncamashi no-Tadpoles.

Izinzuzo Zokuqonda Amagama Ahlukene Esidoda

Ukwazi amagama ahlukene ezicubu zesidoda sowesilisa kuyalusiza ngoba izizwe nemiphakathi ehlukene zisebenzisa amagama azo, okuhlanganisa namagama ezokwelapha kanye nesleng. Ulwazi ngalawa magama lukwenza ukwazi ukufinyelela ebangeni elibanzi lolwazi oluvela emithonjeni eminingi.

Lokhu kusiza futhi ekuqondeni izincwadi, izingxoxo zezokwelapha, kanye namatesti okuxilonga kalula. Kungakhathaliseki ukuthi ufunda umbiko wezokwelapha noma umbhalo ojwayelekile, ukwazi amagama ahlukene esidoda kuqinisekisa ukuthi uyakwazi ukuhluza ulwazi kahle futhi uthole ukuqonda okungcono ngempilo yokuzala.

Okubalulekile

Isidoda yizicubu zokuzala zohlobo lwesilisa ezidala impilo entsha lapho zifika eqandeni futhi zisivundisa emzimbeni wowesifazane. Igama elithi "sperm" yilo elisetshenziswa kakhulu ukubiza izicubu zokuzala zesilisa, kodwa kukhona amanye amagama amaningi okufanele uwazi.

Ukwazi elinye igama lesidoda kungasiza lapho ufunda izincwadi zezokwelapha, ucwaningo, noma izingxoxo ezingahleliwe, ngoba imithombo ehlukene ingase isebenzise amagama ahlukene kuye ngokuthi isetshenziswa kuphi. Ezinye zalezi ziqu ziqhamuka ezincwadini zezokwelapha, kanti ezinye zivela kumatesti okuxilonga noma eslengini. Ukuqonda amagama ahlukene esidoda nendima yaso kukunika umfanekiso ongcono ngenhlalakahle yokuzala kowesilisa.
