Uhlalutyo lwe-spermatozoa

Phakathi kwezinto ezibizwa ngokuba ngamanqaku anquma ukuveliswa kwe-ejaculate yamadoda, kubalulekile ukunyamekela ukuhlalutya kwe-DNA yesininzi (uhlalutyo lofuzo lwesidoda). Inqaku elipheleleyo kukuba ukunyaniseka kwezi zakhiwo kwimizimba yegciwane lentsholongwane kuqinisekisa inkqubo efanelekileyo yokudlulisa izinto eziphathekayo kwimfuyo. Makhe sithethe ngalolu hlobo lophando ngokubanzi kwaye sihlale kwiinkalo eziphambili zokuziphatha kwayo, kunye neenkcukacha zokulungiselela.

Kwiimeko zini na olu luhlobo lwesifundo esabelwe?

Uhlalutyo lwesahluko seDNA esahlukileyo asikwabelwe bonke abantu. Njengomthetho, uncedo lwakhe lisetyenziswe kwezi zilandelayo:

• ukuxilongwa kokungabikho komtshato;
• iinzame ezingaphumeleli zokwenza i-vitro fertilization;
• ukukhulelwa ngokuphindaphindiweyo;
• ubukho bezinto ezingaqhelekanga kwi- spermogram;
• Ukulungiselela ukusetyenziswa kobuchwepheshe bokuncedisa uhlobo lokuzala, njenge- ICSI.

Xa uvavanya uhlalutyo, umphumo ubalwa njengepesenti. Ngoko, ukuphulwa kwe-DNA ye-30% kunye nokunye, ukuxilongwa kokungabikho kwengqondo. Kwindoda enempilo, inambuzane enokuzala okuphezulu, eli nani alidluli kwi-15%. Kufuneka kuqatshelwe ukuba olu phofu luhluke kuhlalutyo kwi-motility ye-spermatozoa, eyenziwa nge-spermogram.

Ziziphi izizathu ezinokuthi ukwanda kwe-DNA ukuhlukana kwenzeka kwi-spermatozoa?

Izizathu zokwandisa isibonakaliso esicatshangelwe kule nqaku zininzi. Ngaphezu koko, kwezinye iimeko, oogqirha abazange bakwazi ukuseka, okukhokelela ekuphulaphuleni kwimeko ethile. Ngokuqhelekileyo phakathi kwezinto ezibangela ukunyuka kwe-DNA ukuhlukana okukhoyo kwiiseli zentsholongwane, ezi zilandelayo ziyaziwa:

• impembelelo emzimbeni wemisebe ye-ionizing;
• ubukho beentsholongwane zentsholongwane kwindlela yokuzala;
• ukufumana umqolo ohlukeneyo weyeza kunye ne-chemotherapy xa kukho izifo eziphilayo;
• utyhefu lomzimba onensimbi enzima (mercury, khokelo);
• imeko ezimbi;
• imfuza;
• iinkqubo ezingapheliyo kwi-genitourinary system (prostatitis, vesiculitis).

Uhlobo lophando luqhutywa njani?

Emva kokunyangwa kwe-ejaculate kunye neeragents ezikhethekileyo, ihlolwe phantsi kwe-microscope ngokunyuka okukhulu. Kule meko, umsebenzi webhubra ubala iiseli ngeDNA ehlukileyo kunye ne-DNA.

Ukulungiselela uhlalutyo lwesilisa kubandakanya ukuyeka ukulala ngesini ubuncinane iintsuku ezingama-3-5 phambi kovavanyo. Ukongezelela, oogqirha banokucebisa ukuba bayeke ukuveza umzimba kumashishini aphezulu, ukutyelela i-sauna, ukuhlamba. Ukuba umntu uthatha nawaphi na amayeza kunyango lweengxaki ezidibeneyo, kuyimfuneko ukuba uxelele ugqirha oyalela ukuba ufunde.

Ukucacisa ukuba uhlalutyo olunjalo lwesilwanyana alukhuni, kodwa lufanele lwenziwe kuphela ngutitshala. Into leyo kukuba ukuhlolwa kwesiphumo kufuneka kwenziwe ngokuqwalasela imeko yenkqubo yesalathiso yesilisa.

Kuza kubekho, kuninzi amaziko ogqirha kunye nezofuzo ezenza olu hlobo lophando. Ngoko ke, xa iingcali ziphendula umbuzo wendawo apho unokwenza uhlalutyo, oogqirha banikela loo ndoda inketho. Kwizixeko ezinkulu kunye namaziko ommandla, njengomgaqo, kukho iinkonzo ezininzi zempilo ezibandakanyekayo ekuqhubeni uphando lwe-ejaculate malunga nokuhlukana kwe-DNA.
