Ingabe singakuyeka ukuguga nokunqamuka kokuya esikhathini unomphela?

Ukuthuthuka okusheshayo kwesayensi ye-stem cell kanye nokwelashwa kokuvuselela kabusha kungasenza sibukeke sibasha isikhathi eside phakathi neminyaka embalwa ezayo. 

Abantu baklanyelwe ukuguga nokushintsha, kodwa ucwaningo lwakamuva lubikezela ukuthi inqubo yokuguga inganqanyulwa futhi ingahlehliswa nangesikhathi esizayo.

I-biomedical gerontologist, u-Aubrey de Grey, ukholelwa ukuthi ukuguga kuyisifo, futhi ngokwandisa, kungaqedwa. Uphinde wathi eminyakeni engu-20 kusukela manje kungenzeka ukuthi ukunqamuka kokuya esikhathini kungasekho. Abesifazane bazokwazi ukuthola izingane kunoma ibuphi ubudala ngemva kokuba umjikelezo wakhe wokuya esikhathini usuqalile.

Abesifazane abangena empeshenini basazobukeka futhi bazizwe sengathi baseminyakeni yabo engamashumi amabili. Imithi yakhe yokulwa nokuguga emsebenzini izonweba umjikelezo wokuzala wesifazane. Imikhawulo yamanje yokukhulelwa nokubeletha ingashabalala ngokwandisa isayensi ye-stem cell kanye nocwaningo lwezindlela zokwelapha ezivuselelayo.

NgokukaDkt. de Grey, i-ovary, njenganoma yisiphi esinye isitho, ingakhiwa ukuze ihlale isikhathi eside. Kuzoba nezinketho zokwelula impilo ye-ovary ngokugcwalisa noma ukuvuselela ama-stem cells, noma ngokudala isitho esisha esisha-esifana nezinhliziyo zokwenziwa.

Lezi zindaba zifika ngesikhathi lapho abantu abaningi bezimisele ukulondoloza ubusha babo; okhilimu abaqeda imibimbi, izithasiselo, neminye imikhiqizo elwa nokuguga iya ngokuya itholakala.

Abanye ochwepheshe bezokuzala bayavuma futhi “baye baqinisekisa ukuthi kube khona intuthuko enkulu ekuqondeni izici zokungazali kwabesifazane kanye nokunciphisa inqubo yokuguga,” ngokwe-Liberty Voice.

ENyuvesi yase-Edinburg, isazi sezinto eziphilayo u-Evelyn Telfer nethimba lakhe labacwaningi bafakazele ukuthi amaqanda owesifazane angakhula ngempumelelo ngaphandle komzimba womuntu. Lokhu kutholakala okujulile kuzosho ukuthi abesifazane abaningi okufanele belashwe umdlavuza bangakhishwa amaqanda abo futhi agcinwe ukuze kube khona umndeni wesikhathi esizayo.

Kunombono ophikisanayo phakathi kwabanye abacwaningi wokuthi alikho inani elingaguquki lamaqanda owesifazane angawakhiqiza njengoba kwakucatshangwa ekuqaleni, kodwa ukuthi “ama-follicle angakasetshenziswa akhona ngemva kokunqamuka kokuya esikhathini okuthi uma exhashazwa, angase asho ukuthi ukuzala kwabesifazane kwandiswa.”

Naphezu kwenqubekelaphambili kanye nenzuzo kwezesayensi, u-Telfer uveza ukuthi kusekude phambili.
