Ukuqonda Ukwakheka Kwesidoda Nokuzala

Ukwakheka kwesidoda kubhekisela ekumeni nasekwakhiweni kwesidoda, okungathinta kakhulu ikhono lesidoda lokuvundisa iqanda. Amadoda anamasidoda anokwakheka okungajwayelekile abe sengozini enkulu yokungabi nenzalo [1].

Isidoda esinempilo sinekhanda elibushelelezi, eliyimfumba eyindilinga nomsila omude osisiza ukuthi sibhukude. Izimo zesidoda ezingajwayelekile zingathinta ikhono laso lokufinyelela nokuvundisa iqanda.

Kujwayelekile ukuthi amanye amasidoda abe nokwakheka okungajwayelekile, kodwa ukuba namasidoda amaningi kakhulu angajwayelekile kunganciphisa amathuba okukhulelwa.

Lesi sihloko sichaza umehluko phakathi kwamangqamuzana esidoda anokwakheka okujwayelekile nalawo anokwakheka okungajwayelekile. Lesi sihloko siphinde sikhulume ngezindlela ezisebenzayo zokuthuthukisa ukwakheka okungajwayelekile kwesidoda nokwandisa amathuba okukhulelwa.

Kuyini Ukwakheka Kwesidoda?

Igama elithi "morphology" livela emagameni esiGreki athi "morph" (ukuma) no "ology" (ucwaningo). Ngakho-ke, incazelo yokwakheka kwesidoda ingaba wucwaningo lokuma kwesidoda.

Lapho sifunda ukwakheka kwesidoda, sifunda izici ezihlukene zamangqamuzana esidoda, okuhlanganisa ukuma kwawo, ukwakhiwa kwawo, nosayizi wawo.

Ukwakheka kwesidoda ivame ukufundwa ngesikhathi sokuhlaziywa kwesidoda (semen analysis), okuyivivinyo elivamile lokuhlola ukuzala kowesilisa.

Iseli lesidoda lakhiwe izingxenye ezintathu eziyinhloko:

• Ikhanda — liphethe ulwazi lwezofuzo (genetic material).
• Ingxenye emaphakathi — inikeza amandla okunyakaza.
• Umsila — ushukumisa isidoda usondele eqandeni.

Ukuma nokwakheka kwalezi zingxenye kunquma ikhono lamangqamuzana esidoda okuvundisa iqanda. Isibonelo, ikhanda elakhiwe kahle libalulekile ekungeneni eqandeni, kanti umsila oqinile uyadingeka ukuze kunyakazwe ngendlela efanele ukufinyelela iqanda.

Ukufunda ukuthi ungakulungisa kanjani ukwakheka kwesidoda kungathuthukisa kakhulu imiphumela yokuzala kowesilisa, ikakhulukazi kulabo ababhekene nobunzima bokukhulelwa.

Indima Yokwakheka Kwesidoda Ekuzaleni Kwabesilisa

Ukwakheka kwesidoda kudlala indima ebalulekile ekuzaleni kowesilisa. Ukuma nokwakhiwa kweseli lesidoda kungathinta ikhono laso lokuvundisa iqanda.

Iseli lesidoda elinokwakheka okujwayelekile linamathuba angcono okufinyelela nokungena ngempumelelo eqandeni. Lokhu kungenxa yokuthi ukuma nokwakheka kweseli lesidoda kuthinta ukunyakaza kwaso.

Ukwakheka kwesidoda okungajwayelekile, njengeziphambeko ekhanda noma emsileni, kungavimba lo mkhuba futhi kuthinte inzalo yabesilisa [2]. Isibonelo, isidoda esinekhanda eliphindwe kabili noma isidoda esine misila emibili singase sibe nenkinga yokunyakaza kahle. Ngisho noma iseli lesidoda elingajwayelekile lifinyelela iqanda, kungenzeka lingakwazi ukulihlaba lingene.

Ngamazwi alula, ukwakheka kwesidoda, njengokubalwa kwesidoda, kuyinto ebalulekile ekuzaleni kowesilisa futhi kuyinto enqumayo ekuphumeleleni kokukhulelwa.

Ukuma Kwesidoda Okuvamile Uma Kuqhathaniswa Nokungajwayelekile

Ukwakheka kwesidoda (sperm morphology) kuhlanganisa usayizi nesimo sesidoda. Ukwakheka okuvamile kwesidoda kuhlanganisa ikhanda eliyimfumba eyindilinga nomsila omude [3].

Inhloko yesidoda iqukethe izinto zofuzo, kanti umsila usishukumisela isidoda siye eqandeni. Noma yikuphi ukuphambuka kulesi sakhiwo kubhekwa njengokuma okungajwayelekile kwesidoda.

Ukuma okungajwayelekile kwesidoda kungahluka. Kungabandakanya izinkinga ngenhloko, ingxenye emaphakathi, noma umsila wesidoda. Tapered head sperm is one of the most common head abnormalities that reduces the sperm’s ability to penetrate the egg during fertilization.

I- Izimfuneko eziqinile zikaKruger uyizinga elisetshenziswa kakhulu ekuhloleni ukuma kwesidoda [4]. Ngokusho kwalezi zimfuneko, indoda ibhekwa njengenenkomba evamile yokuma kwesidoda uma u-14% noma ngaphezulu wesidoda sayo sinomumo ojwayelekile.

Nokho, ukuba nenani eliphansi lamaseli esidoda ajwayelekile kunebanga elivamile lokuma kwesidoda akusho ngempela ukuthi indoda ayinazo nhlobo izitho zokuzala. Amadoda amaningi anamaphesenti aphansi esidoda esijwayelekile ayakwazi ukukwazi ukwandisa inzalo ngempumelelo.

Ngakolunye uhlangothi, iphesenti eliphezulu lesidoda esingajwayelekile lingakhuphula ingozi yokungabi nenzalo. Ucwaningo ikhombisa ukuthi amaseli esidoda angajwayelekile angaholela futhi emazingeni aphezulu okulahlekelwa ukukhulelwa [5].

Izimpawu Zesidoda Esingajwayelekile

Isidoda esingajwayelekile noma ukuma okungajwayelekile kungaba nezimpawu ezahlukene. Ezinye zingaba nezidoda ezinekhanda eliphindwe kabili noma imisila emibili kanti ezinye zingaba nenhloko emise ngokucijile, inhloko engenamumo ocacile, noma umsila ogobile. Ezinye izidoda zingaba nenhloko enkulu kakhulu noma encane kakhulu.

Lokhu kungajwayelekile kungathinta ikhono lesidoda lokufinyelela nokuvundisa iqanda. Isibonelo, isidoda esinhloko emise ngokucijile singase singakwazi ukungena eqandeni nokulivundisa.

Ngokufanayo, isidoda esinemisila emibili singase singakwazi ukubhukuda kahle siye eqandeni. Ngenxa yalokho, amaseli esidoda anezinga eliphansi lokuma okuvamile angafaka isandla ezinkingeni zokungabi nenzalo.

Izimbangela Zokuma Okungajwayelekile Kwesidoda

Uhla lwezinto ezahlukene lungabamba iqhaza ekumeni okungajwayelekile kwesidoda noma esidodeni esonakele. Lezi zinto zingahlanganisa izinkinga zofuzo kuya ezinqumweni zendlela yokuphila. Ukuqonda ukuthi yini ebangela isidoda esingajwayelekile kubalulekile ekwelashweni okusebenzayo; lezi zimbangela zingabandakanya izifo, izinga lokushisa eliphezulu ema-testicle, noma ukuchayeka kumakhemikhali anobuthi emvelweni.

Nazi ezinye zezimbangela ezivamile ezingaholela ekonakaleni kwesidoda noma ekumeni okungajwayelekile kwesidoda:

• Izinkinga Zofuzo: Izinkinga zofuzo ziyimbangela enkulu ebangela ukungajwayelekile kwesidoda. Isibonelo, isimo zofuzo esibizwa ngokuthi i-Klinefelter syndrome singathinta ukukhiqizwa kwesidoda futhi siphelelele ngokuma okungajwayelekile kwesidoda [6].
• Izici Zemvelo: Izici zemvelo ezifana nokuchayeka kumakhemikhali anobuthi nakumangcolisi zingalimaza ikhwalithi yesidoda [7]. Lokhu kuhlanganisa ukubekelwa obala amakhemikhali ezimbonini, insimbi esindayo, nemisebe.
• Indlela Yokuphila: Izinketho ezimbi zendlela yokuphila ezifana nokubhema, ukuphuza utshwala, ukusebenzisa izidakamizwa zokuzijabulisa, ukudla ukudla okungelula, nokungazivocavoci zingafaka isandla ekwakhekeni kwamafomu angajwayelekile esidoda [8]. Izifundo zikhombisa ukuthi ukushisa ngokweqile kwamaqanda ngenxa yezingubo eziqinile nakho kungabangela ukwakheka okungajwayelekile kwesidoda.
• Izimo Zempilo: Ezinye izimo zempilo zingase zithinte ukwakheka kwesidoda. Isibonelo, i\-varicocele, ukuvuvukala kwemithambo esesqotsheni (scrotum), ingabangela ukwenyuka kwezinga lokushisa emaqanda esendaweni yokuzala, okuthinta ukukhiqizwa nokwakheka kwesidoda [9].

Kubalulekile ukuqaphela ukuthi akuzona zonke izimbangela zokungajwayelekile kwamasidoda ezaziwayo. Kwezinye izimo, kungenzeka kungabikho sizathu esicacile sokwakheka okungajwayelekile kwesidoda. Ngakho\-ke, kumelwe ubheke usizo lodokotela uma ubhekene nezinkinga zokungabi nenzalo. Ukungajwayelekile kwesidoda kungabangelwa futhi ukungalingani kwamahomoni noma izifo ezingapheli, ezidinga ukuhlolwa kwezokwelashwa nokungenelela okufanele.

Ukuhlolwa Kokwakheka Kwesidoda

Ukuhlolwa kwesidoda (semen analysis) kuwuhlolo oluvamile lokuzala kwabesilisa oluhlanganisa nokutadisha ukwakheka kwesidoda. Lolu vivinyo lufaka ukuhlolwa kwezinhlangothi ezahlukene zesidoda sendoda kanye namaseli esidoda aqukethwe kuso.

Ngesikhathi sokuhlolwa, kuthathwa isampula yesidoda bese ihlolwa ngaphansi kwe\-microscope. Udokotela bese ehlola umumo nesakhiwo sesidoda ngezibalo zokwakheka kwesidoda ezitholwe nge\-microscope. Lokhu kuhlanganisa ukuhlola usayizi nomumo wekhanda lesidoda, ingxenye ephakathi, nomsila.

Imiphumela ngokuvamile ikhombisa iphesenti. Leli pesenti likutshela ukuthi mangaki amasidoda anomumo ojwayelekile phakathi kwawo wonke amasidoda asesampuleni yesidoda. I Inhlangano Yezempilo Emhlabeni ithi umphumela ojwayelekile uwukuthi uma ngaphezu kuka\-4% wesidoda sinomumo ojwayelekile [10]. Noma yini engaphansi kuka\-4% isemkhawulweni wokwakheka okungajwayelekile kwesidoda.

Kodwa, kubalulekile ukukhumbula ukuthi ukwakheka kwezimfutho zesidoda (semen morphology) kuyisici esisodwa sekhwalithi yesidoda. Ezinye izinto, njengenani lesidoda nokunyakaza kwaso, nazo zinembeza indima enqumayo ekukwazini ukuzala kwendoda.

Indlela Yokulungisa Ukwakheka Kwesidoda

Ukwenza ngcono ukwakheka kwesidoda kubandakanya inhlanganisela yezinguquko ekudleni, izinguquko endleleni yokuphila kanye nezithasiselo zokudla. Nokho, yize wonke umuntu engalandela lezi zindlela, kungenzeka zingasebenzi kumuntu wonke.

Nawa amanye amathiphu asetshenziswa ekuthuthukiseni ukwakheka kwesidoda:

1. Izinguquko Ekudleni Zokwakheka Kwesidoda

Ukudla ukudla okulinganiselayo okunothile ngama\-antioxidant, amavithamini, namaminerali kungasekela ukuthuthuka okuhle kwesidoda.

Ukudla njengamaqebelengwane ezithelo, imifino, amantongomane, ne\-whole grains kunikeza imisoco ebalulekile efana ne\-zinc, i\-vitamin C, ne\-folate, okungakwazi ukuthuthukisa ukwakheka nekhwalithi yesidoda.

Ukunciphisa ukudla okucubunguliwe, amafutha e-trans, notshwala ngokweqile kungasiza futhi ukuthuthukisa ukwakheka kwesidoda, okuholela ekutheni isimo sokuzala sibe ngcono ngokuphelele.

2. Izinguquko Zendlela Yokuphila Zokwakheka Kwesidoda

Ukugcina isisindo somzimba esinempilo kubalulekile empilweni yesidoda ekahle. Ukukhuluphala ngokweqile kungathinta kabi ukwakheka kwesidoda kanye nokuzala konke sekukonke.

Ukubhema nokuphuza utshwala ngokweqile kungalimaza impilo yesidoda. Ngakho-ke, ukuyeka ukubhema nokunciphisa ukusetshenziswa kotshwala kungathuthukisa ukwakheka kwesidoda.

Ukuzivocavoca njalo kungathuthukisa nempilo yesidoda iyonke. Kodwa-ke, ukuzivocavoca ngokweqile kungaba nomphumela ohlukile, ngakho yenza indlela enesisindo esifanele ukuze uthole izinzuzo ezinkulu nobungozi obuncane.

3. Izithasiselo Zokwakheka Kwesidoda

Ukuzala izithasiselo kungasiza ukuthuthukisa ukwakheka kwesidoda ngokunikeza izakhamzimba ezisemqoka ezidingekayo ukukhiqizwa kwesidoda okunempilo. Lokhu kuhlanganisa ama-antioxidant afana namavithamini C no-E, angavikela isidoda ekucindezelekeni okubangelwa i-oxidative stress.

I-zinc ne-folic acid nakho kubalulekile empilweni yesidoda futhi kudlala indima ebalulekile ekwakhekeni nasekukholisweni (maturation) kwesidoda.

Amafutha e-Omega-3, atholakala ezinhlanzini nasezinhlanyelweni ze-flax, nawo angathinta kahle ukwakheka kwesidoda. Kodwa-ke, kubalulekile ukubonana nochwepheshe bezempilo ngaphambi kokuqala noma yiluphi uhlelo olusha lwezithasiselo.

Amasu Okuzala Asizwa Ngobuchwepheshe (ART) Nokwakheka Kwesidoda

Amasu Okuzala Asizwa Ngobuchwepheshe (ART) angaba inketho esebenzayo yabantu abashadile ababhekene nezinselele ekukhulelweni ngenxa yokwakheka kwesidoda [11]. Amasu anjenge-Intrauterine Insemination (IUI) ne-In Vitro Fertilization (IVF) angasiza ukunqoba lezi zinkinga.

Ikakhulukazi, i-Intracytoplasmic Sperm Injection (ICSI) ivame ukusetshenziswa ku-IVF ukuze kunqotshwe izinkinga zokwakheka kwesidoda. Le ndlela ihilela ukufaka isidoda esisodwa ngqo eqandeni, kugwemeke isidingo sokuthi isidoda singenele iqanda sodwa.

Kodwa-ke, kubalulekile ukuxoxa nochwepheshe bezempilo ngezinketho zokwelapha ukungajwayelekile kokwakheka kwesidoda ukuze uqonde ubungozi obungaba khona nezinzuzo.

Nini Okufanele Ubone Uchwepheshe

Uma unenkinga yokukhulelwa futhi usola ukuthi ukwakheka kwesidoda kungase kube nomthelela, kubalulekile ukubonana nochwepheshe wezokuzala. Bangakwazi ukwenza i-semen analysis ukuhlola impilo yesidoda, kuhlanganise nokwakheka kwaso.

Ochwepheshe abanjengethaba lodokotela abelapha izifo zesitho sangasese sowesilisa (urologists) nochwepheshe bezomzimba wokuzala (reproductive endocrinologists) bangakuhola ngokuxilongwa okwengeziwe nezinketho zokwelashwa. Bangakuchazela nangemiphumela yakho futhi bakusize uhlele izinyathelo ezilandelayo.

Khumbula, ukuxilongwa kusenesikhathi nokungenelela kungaba yisihluthulelo ekubhekaneni nezinkinga zokungabi nenzalo kwabesilisa. Ngakho-ke, ungabambezeleki noma uzizwe unehloni ukukhuluma nodokotela wakho ngezempilo yakho yokuzala.

Imibuzo evame ukubuzwa

1. Ukwenza kanjani ukuze ukhulelwe uma ukubunjwa kwesidoda kungesihle?

Izindlela zokuzala ezisizwa ubuchwepheshe, njenge-IVF, zingakhulisa kakhulu amathuba okukhulelwa uma kunokubunjwa kwesidoda okungesihle. Lezi zindlela zenza kube nokwenzeka ukukhetha nokusebenzisa isidoda esinempilo kakhulu ukuze kwandiswe ithuba lokukhulelwa eliyimpumelelo.

2. Ingabe isidoda esingajwayelekile singavundisa iqanda?

Isidoda esingajwayelekile ngezinye izikhathi singavundisa iqanda, kodwa singanciphisa amathuba okuba khona kokuvundiswa okuyimpumelelo futhi siholele ezinkingeni.

3. Yini ekhombiswa umphumela wokuhlolwa kwesidoda okuthi sperm morphology 1 percent?

Ukubunjwa kwesidoda ngo-1 percent kubonisa ukuthi ngaphansi kuka-1 percent wamaseli akho esidoda anokubunjwa okuvamile.

4. Ingabe i-personal lubricant ingalimaza isidoda?

Yebo, i-lubricant evamile ingakha umgoqo ekungeneni kwesidoda okungaphakathi, okuholela ku-oxidative stress nokuphazamisa ulwelwesi lwe-flagella yesidoda. Ngisho nezinye ama-lubricant abhalwe ukuthi anobungane esidodeni angaqhubeka alimaze. I-FDA icacisile ukuthi i-Conceive Plus fertility lubricant ingelinye i-lubricant elinobungane ekuzaleni elikhombiswayo ukuthi alilimazi isidoda.

Okubalulekile ekugcineni

Ukubunjwa kwesidoda (sperm morphology) kuyisici esibalulekile ekuzaleni futhi kuyinto enkulu empumelelweni yokukhulelwa. Isidoda esinesimo esingajwayelekile singenza kube nzima ukukhulelwa. Nokho, khumbula ukuthi ukubunjwa kwesidoda akusona sodwa isici sobudoda bokuzala, kukhona nezinye izinto ezibalulekile eziningana, njengesibalo sesidoda.

Ukuthuthukisa impilo yesidoda kungahlanganisa izinguquko empilweni ojwayele ukuyiphila, ama-supplement, noma ukwelashwa kwezokwelapha. Ukubonana nochwepheshe bezempilo kubalulekile ukuze uthole iseluleko nokwelashwa okwenzelwe wena. Ngokubekezela nangesimo sengqondo esihle, ungakwazi ukuqhuba kahle ezinselele zokungabi nenzalo. Khumbula, awuwedwa, futhi kukhona ukwesekwa.
