Umhlahlandlela Ophelele Wokuzala Emadodeni: Impilo Yesidoda, Ukuhlolwa Nezithasiselo zango-2026

Lapho izithandani ziqala uhambo lwazo lokuya ekubeni ngabazali, izingxoxo ngokuzala kuvame ukugxila kakhulu kwabesifazane. Kodwa ukungazali okuvela ohlangothini lwesilisa kunikela cishe esigcawini sengxenye yezinkinga zokukhulelwa, ngokusho kweNhlangano Yezempilo Yomhlaba. Ukuqonda ukuzala kowesilisa — lokho okuthinta kona, indlela yokukuhlola, nendlela yokukuthuthukisa — kubalulekile kuyo yonke imibhangqwana ethemba ukukhulelwa. Lo mhlahlandlela ophelele uhlanganisa konke okudingeka ukwazi mayelana nempilo yesidoda, ukuhlaziywa kwesidoda, izici ezithinta ukuzala kowesilisa, namasu asuselwa ebufakazini okwandisa amathuba enu okukhulelwa ngo-2026.

Noma ngabe usanda kuqala ukuzama ukukhulelwa noma usube uselolu hambo isikhathi eside, lo mhlahlandlela ukukwazisa ngolwazi lwesayensi lwamanje olusekelwe ebufakazini. Kusukela ekuhumusheni umbiko wokuhlaziywa kwesidoda kuya ekuqondeni ukuthi yimaphi ama-supplement asebenzayo ngempela, sizohamba sonke isithombe sempilo yokuzala kowesilisa ukuze ukwazi ukubhekana nalolu hambo ngokuzethemba nangokuqonda.

Ukuqonda Ukuzala Kowesilisa: Isayensi Engemuva Kwempilo Yesidoda

Ukuzala kowesilisa kuncike kakhulu ekwizinga nasekubuningi kwesidoda okukhiqizwayo. Nsuku zonke, umzimba wendoda enempilo ukhiqiza cishe amasidoda angu-1 500 njalo ngokushaya kwenhliziyo — lokho cishe kungamasigidi angu-50 kuya ku-150 wesidoda kumililitha ngayinye yoketshezi lwesidoda. Kodwa akusho ukuthi wonke la masidoda afana, futhi ukuqonda izilinganiso ezisemqoka ezikhalwa ekutholeni ukuhlaziywa kwesidoda kuyisisekelo sokuhlola ukuzala kowesilisa.

Impilo yesidoda ihlolwa ezicini eziningana: inani (kubalwa ukuthi mangaki amasidoda akhona), ukunyakaza (ukuthi nyakaza kahle kangakanani), ukuma (ukwakheka nokuhleleka kwesidoda), kanye nomthamo (isamba sonke soketshezi lwesidoda). Ngokwezinani zokubhekisela zango-2021 zeNhlangano Yezempilo Yomhlaba, ukuhlolwa kwesidoda okuvamile kuhlanganisa ukugxila okungenani kumasigidi angu-16 esidoda kumililitha ngayinye, okungenani u-42% wawo ekhombisa ukunyakaza okuqhubekayo nokungenani u-4% enokuma okujwayelekile.

Inqubo yokukhiqizwa kwesidoda, okubizwa ngokuthi i-spermatogenesis, ithatha cishe izinsuku ezingu-72 kuya kwezi-74. Lolu ulwazi olubalulekile ngoba lusho ukuthi izinguquko zendlela yokuphila ozenzayo namuhla azizukubonisa umthelela ophelele kuze kudlule cishe izinyanga ezintathu. Lokhu futhi kusho ukuthi ukuchayeka kwemvelo — ukushisa, ubuthi, izifo — kungathinta izinga lesidoda izinyanga eziningana ngemuva kwaleso sehlakalo. Ukuqonda lesi sikhathi soshintsho kusiza izithandani ukuhlela kahle imizamo yabo yokukhulelwa nokugcina ukubekezela ngenqubo.

Amahomoni adlala indima esemqoka ekuzaleni kwabesilisa. I-testosterone, i-luteinizing hormone (LH), kanye ne-follicle-stimulating hormone (FSH) basebenzisana ukulawula ukukhiqizwa kwesidoda. Ukuphazamiseka kule ndima yamahomoni — kungaba ngenxa yokucindezeleka, izifo, noma amakhemikhali aphazamisa amahomoni — kungaholela ngokulandelana ekuphazamisekeni kokukhiqizwa kwesidoda. Ucwaningo olushicilelwe kwiphephabhuku i-Human Reproduction Update luthole ukuthi inani lesidoda emadodeni aseNtshonalanga lehle ngaphezu kuka-50% eminyakeni engamashumi amane edlule, okugqamisa ukubaluleka kokuqonda nokuvikela impilo yokuzala kwabesilisa.

Izinto Ezisemqoka Ezithinta Ukuzala Kwabesilisa

Kunezinto eziningi ezithinta ukuzala kwabesilisa, kusukela ekuthambekeni kofuzo kuya ezinqumweni zempilo zansuku zonke. Ukuqonda lezi zinto kuyisinyathelo sokuqala sokuzilungisa ngendlela esebenzayo.

Iminyaka: Nakuba amadoda egcina amandla okuzala isikhathi eside kunezabesifazane, ikhwalithi yesidoda iyancipha ngokuhamba kweminyaka. Ucwaningo lubonisa ukuthi ukucekelwa phansi kwe-DNA yesidoda kuyanda ngokuhamba kweminyaka, futhi amadoda aneminyaka engaphezu kwengu-45 angase abhekane nesikhathi eside ngaphambi kokukhulelwa uma kuqhathaniswa namadoda amancane. Ukuguquka kwezakhi zofuzo ku-DNA yesidoda nako kuyaqhubeka nokwanda, okungenza kube nomthelela ekhulwini lekhwalithi yembungu nasekuphumeni kokukhulelwa.

Ukuvezwa ekushiseni: Amasende atholakala ngaphandle komzimba ngenxa yesizathu esithile — ukukhiqizwa kwesidoda kudinga izinga lokushisa elingaba ngu-2°C ngaphansi kwezinga lokushisa eliyinhloko lomzimba. Ukuvezwa isikhathi eside ekushiseni okuvela emachibini ashisayo, ema-sauna, kumalaptop abekwe emathangeni, noma ngisho nangokugqoka izingubo zangaphansi eziqinile kungaphazamisa okwesikhashana ukukhiqizwa kwesidoda. Izifundo zibonisa ukuthi ukushintshela ezingubeni zangaphansi ezikhululekile nokugwema imithombo yokushisa eyeqile kungathuthukisa izimfanelo zesidoda phakathi kwezinyanga ezintathu.

I-Varicocele: I-varicocele ukuvuvukala kwemithambo yegazi esikhumbeni (scrotum), okufana nemithambo evuvukele emilenzeni (varicose veins). Yona imbangela evame kakhulu futhi engalungiseka yokungabi nenzalo kwabesilisa, etholakala cishe ku-15% wabo bonke obaba besilisa naku-35% wamadoda anokungabi nenzalo kwasekuqaleni. Ama-varicocele anyusa izinga lokushisa esikhumbeni futhi aphazamise ukukhiqizwa kwesidoda. Ukulungiswa ngokuhlinzwa kukhonjisiwe ukuthi kuthuthukisa amazinga esepha yesidoda kanye namazinga okukhulelwa kubashadile abathintekile.

Ukubhema notshwala: Kokubili ugwayi nokusetshenziswa kotshwala ngokweqile konakalisa kakhulu ikhwalithi yesidoda. Ukubhema ugwayi kuhlotshaniswa nokuncipha kwenani lesidoda, ukunganyakazi kahle, nokwanda kokulimala kwe-DNA. Ukuphuza kakhulu utshwala kuphazamisa ukukhiqizwa kwe-testosterone futhi kungaholela ekungalinganeni kwamahomoni okwehlisa ukuzala. Ukunciphisa noma ukuyeka le mikhuba kungenye yezinguquko ezinamthelela omkhulu indoda engazenza ukuze ithuthukise amandla ayo okuzala.

Ingcindezi ye-oxidative: Inani eliningi lama-reactive oxygen species (ROS) emgudwini wokuzala lingalimaza i-DNA nesembozo sesidoda. Imithombo yengcindezi ye-oxidative ifaka ukutheleleka, ukuvuvukala, ukungcola kwemvelo, nokudla okungelona elinempilo. Izakhi zokudla ezisebenza njenge-antioxidant zidlala indima ebalulekile ekuvikeleni isidoda kulokhu kulimala, yingakho ukudla okunempilo nokwengezwa kwemithi yokondla kubaluleke kakhulu ekuthuthukiseni ukuzala kwabesilisa.

Ukuhlolwa Kokuzala Kwabesilisa: Okulindelekile Nokuthi Uzilungiselele Kanjani

Ukuhlaziywa kwesidoda kuwumthombo oyinhloko wokuxilonga uma kuhlolwa ukuzala kwabesilisa. Nakuba kuyivivinyo elilula, elingadabukisi, amadoda amaningi abambezeleka ukwenza lolu vivinyo ngenxa yokuzizwa ehlazekile noma ukungaqondi kahle ukuthi luhilelani. Ukuqonda inqubo kungasuswa ihlazo futhi kukhuthaze ukuthi kuhlolwe kusenesikhathi.

Indlela ukusebenza ngayo ukuhlaziywa kwesidoda: Isampula iqoqwa ngokuziphulula ngemuva kwezinsuku ezingu-2-5 zokuzila ucansi. Isampula sihlaziywa kungakapheli ihora kusukela siqoqwe ukuze kubhekwe ivolumu, i-pH, ukugxila kwesidoda, inani eliphelele lesidoda, ukunyakaza (okuhambayo kahle nokuphelele), ukwakheka, nezinye izinkomba. Ezinye izikhungo ziphinde zihlolise amaseli amhlophe egazi (akhombisa ukutheleleka okungenzeka) nama-antisperm antibodies.

Okuchaza imiphumela: Imiphumela iqhathaniswa namanani abhekisiswe yi-WHO. Kubalulekile ukuqaphela ukuthi umphumela owodwa ongajwayelekile awuqinisekisi ukungazali — ikhwalithi yesidoda iyashintsha kuye ngokugula kwakamuva, ukucindezeleka, indlela yokudla, nezinye izici. Odokotela abaningi batusa ukuphinda ukuhlolwa ezinyangeni ezingu-2-3 ngemuva komphumela ongajwayelekile, ikakhulukazi uma kube nomkhuhlane noma ukugula kwakamuva.

Ukuhlolwa okuthuthukile: Uma ukuhlaziywa kwesidoda okujwayelekile kukhombisa okungajwayelekile, kungase kuyalelwe ezinye izivivinyo. Ukuhlolwa kokuhlakazeka kwe-DNA yesidoda kuhlola ubuqotho bezinto zofuzo ngaphakathi kwesidoda — ukucekeleka okuphezulu kuhlotshaniswa nokuphuphuma kwesisu okuqhubekayo nokwehluleka kwemijikelezo ye-IVF ngisho nalapho izinkomba eziyisisekelo zesidoda zibukeka zijwayelekile. Izivivinyo zegazi zamahomoni (FSH, LH, i-testosterone, i-prolactin) zisiza ukuthola izimbangela zamahomoni. Kwezinye izimo, ukuhlolwa kofuzo (i-karyotype, ukuhlaziywa kokusulwa okuncane ku-chromosome Y) kuyadingeka.

Ukuhlolwa ekhaya: Sekukhona izivivinyo zesidoda zasekhaya eziningi ezigunyazwe yi-FDA, kuhlanganise namadivayisi axhunywa kumaselula ukuze kwenziwe ukuhlaziywa okuningiliziwe. Nakuba lezi zinikeza ulwazi lokuqala olulula, azibuyiseli indawo yokuhlaziywa okuphelele kwesidoda esibhedlela futhi kufanele kulandelwe ukuhlolwa kochwepheshe uma kutholakala okungajwayelekile.

Ukulungiselela ukuhlaziywa kwesidoda (semen analysis): Ukuze uthole imiphumela enembile kakhulu, gwema ukuphuma kwesidoda (ejaculation) izinsuku ezingu-2-5 ngaphambi kokuhlolwa (kodwa hhayi isikhathi eside kakhulu, ngoba ukuzila isikhathi esingaphezu kwezinsuku ezi-5 kunganciphisa ukunyakaza). Gwema utshwala, ama-hot tub, nokushisa okuphezulu okukhulu okungenani izinyanga ezi-3 ngaphambi kokuhlolwa. Yazisa umhlinzeki wakho wezempilo ngayo yonke imithi, izithasiselo, noma izifo zakamuva.

Ukudla Nokondleka Kwempilo Yesidoda Engcono Kakhulu

Ubudlelwane phakathi kokudla nokwenzeka kahle kwesidoda bufakazelwe kahle ezincwadini zesayensi. Ukudla kwaseMediterranean — okunothe ngezithelo, imifino, okusanhlamvu okuphelele, amaprotheni anenoni eliphansi, namafutha anempilo — kuhlotshaniswe ngokungaguquki nokuba ngcono kwezinkomba zesidoda nokuthuthuka kwemiphumela yokuzala emadodeni. Ngokuphambene nalokho, ukudla okunothe ngokudla okucubunguliwe, ama-trans fat, namakhabhohayidrethi acwengiweyo kuhlotshaniswe nekhwalithi embi yesidoda.

Izakhamzimba ezibalulekile empilweni yesidoda:

I-Zinc mhlawumbe iyiminerali ebaluleke kakhulu ekuzaleni kwabesilisa. Ibalulekile ekukhiqizweni kwe-testosterone, ekwakhekeni kwesidoda, nasekuqiniseni i-DNA yesidoda. Amasende aqukethe amanye amazinga aphezulu kakhulu e-zinc emzimbeni. Ukudla okunothe nge-zinc kuhlanganisa ama-oyster, inyama yenkomo, imbewu yekhabishi (pumpkin seeds), nobeans. Ucwaningo lubonise ukuthi ukuntuleka kwe-zinc kuhlotshaniswa ngokuqondile nokwehla kwesibalo sesidoda nokwanda kokwephuka kwe-DNA.

I-Folate akusiyo eyezintokazi kuphela — amadoda ayiyidinga nawo. I-folate (vitamin B9) ibalulekile ekwakhekeni nasekulungisweni kwe-DNA. Amazinga aphansi e-folate emadodeni ahlotshaniswa nokwanda kokuphazamiseka kwamachromosome esidodeni (sperm aneuploidy) nokwehla kwesibalo sesidoda. Imithombo emihle yokudla ifaka imifino eluhlaza enamagqabunga, ama-legume, nokudla okuqiniswe ngamavithamini.

Ama-antioxidant afaka amavithamini u-C no-E, i-selenium, ne-coenzyme Q10 (CoQ10) avikela isidoda ekulimaleni okubangelwa i-oxidative stress. Izifundo zitholile ukuthi amadoda anokungazali avame ukuba namazinga aphezulu e-oxidative stress esidodeni sabo. I-CoQ10 ivelele kakhulu — ukuhlaziywa okuhlanganisayo (meta-analysis) okushicilelwe ku-Journal of Urology kuthole ukuthi izithasiselo ze-CoQ10 zithuthukise kakhulu ukugxila kwesidoda, ukunyakaza, nokwakheka kwaso.

Ama-fatty acid e-omega-3 abalulekile ekuthambekeni nasekusebenzeni kwe-membrane yamaseli ezidoda. Ucwaningo lukhombisa ukuthi amadoda adla kakhulu i-omega-3 abe nokwakheka (morphology) kwesidoda okungcono. Inhlanzi enonomele, ama-walnut, ne-flaxseed imithombo emihle kakhulu. I-DHA (docosahexaenoic acid), uhlobo oluthile lwe-omega-3, igxile kakhulu emaselini ezidoda futhi idlala indima enqubweni yokuchumisa.

I-L-carnitine ne-acetyl-L-carnitine zisekela ukunyakaza kwesidoda ngokunikeza amandla kuma-mitochondria emisileni yesidoda. Izifundo eziningi zasesibhedlela zibonise ukuthuthuka ekunyakazeni kwesidoda uma kusetshenziswa izithasiselo ze-L-carnitine, ikakhulukazi emadodeni anesifo esibizwa ngokuthi i-asthenospermia (ukunyakaza okuphansi).

Izithasiselo Ezisekelwe Ebufakazini Zokuthuthukisa Ukuzala Kwabesilisa

Nakuba ukudla okunempilo nokulinganiselayo kwakha isisekelo sokudla okuhle kokuzala kwabesilisa, izithasiselo eziqondiswe kahle zingasiza ukugcwalisa izikhala futhi zinikeze amazinga okwelapha alezi zakhi ezisemqoka. Imakethe yezithasiselo zokuzala kwabesilisa ikhule kakhulu, kodwa ikhwalithi nokwakheka kwemikhiqizo kubaluleke kakhulu.

Coenzyme Q10 (CoQ10): Njengoba iyinhlanganisela ye-antioxidant futhi iyingxenye ebalulekile ekukhiqizeni amandla emaselula, i-CoQ10 ikhombise izinzuzo ezizinzile ekukwazini ukuzala kwabesilisa ocwaningweni lwezokwelapha. Uhlaka lwezifundo olubuyekeziwe ku-Cochrane Database lwathola ukuthi ukusebenzisa i-CoQ10 kuthuthukisa ukunyakaza nokugxila kwesidoda uma kuqhathaniswa ne-placebo. Ingxenye emaphakathi yesidoda egcwele i-mitochondria idinga i-CoQ10 ukuze kukhiqizwe amandla aqhubekisela phambili ukunyakaza kwesidoda.

Zinc ne-Selenium: Lezi ziminerali zisebenzisana ukuvikela isidoda ekulimaleni okubangelwa i-oxidative stress nokusekela ukukhiqizwa kwe-testosterone. I-selenium ibaluleke kakhulu ekwakhekeni kwe-selenoprotein P, esiza ukunciphisa ama-reactive oxygen species endleleni yokuzala kowesilisa. Izifundo eziningi ezilawulwayo ezihleleke kahle zikhombisile ukuthi ukusetshenziswa ndawonye kwe-zinc ne-selenium kuthuthukisa ukunyakaza kwesidoda futhi kunciphisa ukuhlukana kwezingcezu ze-DNA.

Vitamin D: Ucwaningo olusha selukhombisile ukuxhumana okuqinile phakathi kwezinga le-vitamin D nokukwazi ukuzala kwabesilisa. Ama-receptor e-vitamin D akhona kuyo yonke indlela yokuzala kowesilisa, futhi i-vitamin D idlala indima ekukhiqizeni i-testosterone, ekuthuthweni kwe-calcium kwisidoda, nasekuthuthukiseni ukunyakaza kwesidoda. Izifundo zithole ukuthi amadoda anamazinga anele e-vitamin D anokunyakaza kwesidoda okungcono kakhulu uma kuqhathaniswa nalawo anokuntuleka.

Inhlanganisela ye-folic acid ne-zinc: Ucwaningo olubalulekile olushicilelwe ku-Fertility and Sterility lwathola ukuthi ukusetshenziswa ndawonye kwe-folic acid ne-zinc kwandisa inani eliphelele lamasidoda ajwayelekile ngo-74% emadodeni anezinkinga zokuzala. Le nhlanganisela ibhekana kokubili nokwakheka kwe-DNA (ngomsebenzi we-folate) kanye nokuvikelwa yi-antioxidant nokusekela i-testosterone (ngomsebenzi we-zinc).

I-Conceive Plus Men's Fertility Support iqukethe inhlanganisela ecwaningwe ngokucophelela yalezi zakhi ezisemqoka — i-CoQ10, i-zinc, i-selenium, i-folate, i-L-carnitine, nokunye okuningi — elungiselelwe ngokukhethekile ukusekela zonke izici zempilo yesidoda. Lapho ukhetha isengezo, funa imikhiqizo esebenzisa izinhlobo zezinto ezitholakala kalula emzimbeni ngayinye futhi enezinhlu zezithako ezicacile ezinezilinganiso eziqinisekiswe ocwaningweni lwezokwelapha.

Ukwenza Ngcono Indlela Yokuphila Ukuze Kuthuthukiswe Ukuzala Kwesilisa

Ngaphezu kokudla nokwengeza izithasiselo, kunezinguquko eziningana endleleni yokuphila eziqinisekiswe ngesayensi ukuthuthukisa ukuzala kwabesilisa. Lezi zinguquko zisebenzisana kahle nokulungiswa kokudla ukuze kwakheke indawo ekahle yokukhiqizwa kwesidoda esinempilo.

Ukuzivocavoca: Ukuzivocavoca okulingene, okuvamile, kuzosiza ukuzala kwabesilisa ngokuthuthukisa ukujikeleza kwegazi, kunciphise ukucindezeleka kwe-oxidative, futhi kusekele amazinga e-testosterone anempilo. Ucwaningo luthole ukuthi amadoda azivocavoca njalo anezinkomba zesidoda ezingcono kunamadoda ahlala kakhulu enganyakazi. Nokho, ukuzivocavoca ngokweqile — ikakhulukazi ukugibela amabhayisikili ibanga elide noma ukuqeqeshwa okunzima kokubekezela — kungaphazamisa isikhashana ukuzala ngenxa yokushisa, ukucindezeleka nokuphazamiseka kwamahomoni. Hlose okungenani imizuzu engu-150 ngomsebenzi wokuphefumula ongaphakathi nendawo ngeviki ohambisana nokuzivocavoca kwamandla.

Ukulawula ingcindezi: Ingcindezi yengqondo ivuselela i-hypothalamic-pituitary-adrenal (HPA) axis, ikhuphule amazinga e-cortisol aphazamisa ukukhiqizwa kwe-testosterone nekhwalithi yesidoda. Ucwaningo lubonise ukuthi amadoda abhekene nengcindezi enkulu yokuphila abe nokugxila kwesidoda nokunyakaza kwaso okuphansi. Ukuzindla okunokuqaphela, i-yoga, ukulala njalo, nokwesekwa ngabanye bonke kukhonjisiwe ukuthi kwehlisa ingcindezi futhi kuthuthukise amahomoni okuzala kwabesilisa.

Ukulala: Ukulala yisikhathi umzimba owenza ngaso imisebenzi ebalulekile yokulungisa nokuvuselela, okuhlanganisa ukukhiqizwa kwe-testosterone (okufinyelela phezulu ngesikhathi sokulala okujulile). Ucwaningo olushicilelwe ku-American Journal of Epidemiology luthole ukuthi amadoda alala ngaphansi kwamahora angu-6 noma ngaphezu kwamahora angu-9 ubusuku ngabunye abe nenani lesidoda eliphansi kakhulu kunalawo alala amahora angu-7–8. Ukubaluleka kokulala okuhle, okuhlelekile, kuyindlela elula kodwa enamandla yokuthuthukisa ukuzala.

Ukugwema ubuthi bezemvelo: Amakhemikhali aphazamisa ama-endocrine (EDCs) atholakala epulasitiki (BPA, phthalates), emanyolo ezinambuzane, kumakhemikhali ezimboni, nasemikhiqizweni yokunakekela umzimba anga­phazamisa izimpawu zamahomoni nokukhiqizwa kwesidoda. Izinyathelo ezisebenzisekayo zihlanganisa ukukhetha iziqukathi zokugcina ukudla zengilazi noma zensimbi engagqwali, ukukhetha imikhiqizo yezolimo ye-organic lapho kungenzeka, nokukhetha imikhiqizo yokunakekela umzimba engenawo ama-parabens namaphunga enziwe ngemikhiqizo yokwenziwa.

Ukugcina isisindo esinempilo: Ukukhuluphala ngokweqile kuhlotshaniswa nokwehla kwamazinga e-testosterone, ukwanda kwe-estrogen, ukwanda kwezinga lokushisa lesikhwama samasende, nokuphazamiseka kokukhiqizwa kwesidoda. Ngisho nokwehla okuncane kwesisindo emadodeni akhuluphele kukhonjisiwe ukuthi kuthuthukisa amazinga e-testosterone nezinkomba zesidoda. I-body mass index (BMI) ephuma ebangeni elijwayelekile — kokubili ukukhuluphala nokungondleki — kuhlotshaniswa nekhwalithi yesidoda ephansi.

Ukwelashwa Ngokwezokwelapha Kukungabi Nabantwana Kwabesilisa

Lapho izinguquko zendlela yokuphila nezithasiselo zingeneleli, kungase kudingeke ukungenelela kwezokwelashwa. Intuthuko kwezokwelashwa kokuzala iye yanwebisa kakhulu izinketho ezitholakalayo kumadoda abhekene nezinselelo zokuzala.

Ukulungiswa kwe-varicocele: Ukuhlinzwa kokulungisa i-varicocele (varicocelectomy) noma ukuvala imithambo ye-varicocele nge-embolization yikho ukuhlinzwa okuvamile kakhulu ekwelapheni ukungazali kwamadoda. Ukuhlaziywa okuhlanganisiwe (meta-analyses) kukhombisile ukuthuthuka okukhulu ezinkombeni zesidoda ngemva kokulungiswa, kanti namazinga okukhulelwa ngokwemvelo ayakhuphuka kakhulu emabhodlewaneni lapho owesifazane engenankinga yokuzala.

Ukwelashwa ngamahomoni: Amadoda anokungalingani kwamahomoni okubangela ukukhiqizwa okuphansi kwesidoda (hypogonadotropic hypogonadism) avame ukwelashwa ngemijovo yama-gonadotropin (FSH ne-LH) noma i-clomiphene citrate, ekhuthaza umzimba ukuba ukhiqize amahomoni awo. Lokhu kwelashwa kungathuthukisa kakhulu ukukhiqizwa kwesidoda ezigulini ezikhethiwe ezifanele.

Izindlela zokukhipha isidoda: Emadodeni anganalo nhlobo isidoda ekuchameleni (azoospermia), isidoda sivame ukukhishwa ngqo emabeleni wesende ngokuhlinzwa okunjengokukhipha isidoda esivela esendeni (TESE) noma i-microdissection TESE (micro-TESE). Lesi sidoda singase sisetshenziswe ku-IVF ene-intracytoplasmic sperm injection (ICSI), okungaholela ezingeni lokukhulelwa elifanayo nelamabhodlewane lapho ukungazali kowesilisa kungasibi kakhulu.

Nini okufanele ubone uchwepheshe: Uma umbhangqwana esehlulekile ukukhulelwa isikhathi sezinyanga ezingu-12 (izinyanga ezi-6 uma owesifazane eneminyaka engaphezu kwengu-35), bobabili kufanele bahlolwe ukuzala kwabo. Ukuhlolwa kowesilisa kufanele kuqale ngokuhlaziywa kwesidoda. Udokotela ohlinzayo wezifo zomchamo okhethekile ekungazali kwamadoda noma udokotela okhethekile ekushintsheni kwamahomoni okuzala (reproductive endocrinologist) angahola izinyathelo ezilandelayo ngokusekelwe emiphumeleni.

Nini Okufanele Ufunisise Usizo Nokuhamba Phambili

Ukuzala kowesilisa kuyindaba eyinkimbinkimbi futhi eyimfihlo kakhulu, kodwa futhi kuyindawo lapho izinyathelo ezithathwayo kusenesikhathi zingaletha umehluko obalulekile. Isinyathelo sokuqala wukuzihlolela — ukuhlaziywa kwesidoda kunikeza umbono ocacile ngokuthi umi kuphi nokuthi yiziphi, uma zikhona, izindlela zokungenelela ezingase zikusize. Abaningi amadoda bayamangala ukuthola ukuthi izinguquko eziqondile ekudleni, empilweni yonke, nasezithasiselweni zingathuthukisa kakhulu izinkomba zesidoda phakathi nezinyanga ezimbalwa.

Khumbula ukuthi umjikelezo wokukhiqizwa kwesidoda wezinsuku ezingu-72–74 usho ukuthi izinguquko ozenzayo namuhla — kungaba ukuyeka ukubhema, ukuqala isithasiselo sokuzala, noma ukuthuthukisa indlela odla ngayo — zizoveza umthelela wazo ophelele cishe ezinyangeni ezintathu ezizayo. Lokhu akusona isizathu sokubambezela; kuyisizathu sokuqala manje.

Izinselelo zokuzala zingaba nzima ngokomzwelo, futhi kubalulekile ukuthi bobabili ozakwenu basekelane kulo msebenzi. Izinsiza ezifaka onogada bokuzala, amaqembu okusekelwa, nezinto zokufunda zingasiza imibhangqwana idlule kulo hambo ndawonye. Ngolwazi olufanele, ukusekelwa, nezinqubo ezifanele, imibhangqwana eminingi ebhekene nokungazali okubangelwa isici sowesilisa iyakwazi ukufinyelela iphupho labo lokuba ngabazali.

Imibuzo Evame Ukubuzwa Ngokuzala Kwabesilisa

Kuthatha isikhathi esingakanani ukuthuthukisa impilo yesidoda?

Ngenxa yokuthi isidoda sithatha cishe izinsuku ezingu-72-74 ukuthi sithuthuke, ukuthuthuka okubalulekile kumapharamitha esidoda kuvame ukubonakala emva kwezinyanga ezingu-3 selokhu kwaqalwa izinguquko ekudleni, endleleni yokuphila, noma ekuthatheni izithasiselo. Ezinye izinguquko — ikakhulukazi ekunyakazeni kwesidoda — zingabonakala kusenesikhathi, kodwa ukuhlolwa okuphelele kufanele kwenziwe okungenani emva komjikelezo owodwa ophelele wokukhiqizwa kwesidoda.

Ithini inani lesidoda elijwayelekile?

Ngokwezindinganiso zereferensi ze-WHO zango-2021, ukugxila kwesidoda okujwayelekile kungama-16 million noma ngaphezulu ngomamililitha ngamunye, nenani eliphelele lesidoda lama-39 million noma ngaphezulu ekukhishweni kwesidoda ngakunye. Nokho, lezi yizindinganiso zereferensi, hhayi imingcele eqondile yokuzala — amadoda anenani elingaphansi kwale mikhawulo asakwazi ukuthola ukukhulelwa, futhi nalawo angenhla kwazo asengase abhekane nezinselelo zokungazali.

Ngabe ukucindezeleka ngempela kungathinta ukukwazi ukuzala kowesilisa?

Yebo, ukucindezeleka okuqhubekayo kuboniswe ukuthi kwenyusa amazinga e-cortisol, okungacindezela ukukhiqizwa kwe-testosterone futhi konakalise ikhwalithi yesidoda. Izifundo eziningi zithole ukuxhumana phakathi kokucindezeleka ngokwengqondo nokwehla kwenani, ukunyakaza, nokuma kwesidoda. Amasu okulawula ukucindezeleka afana nokuzindla, ukuzivocavoca, nokulala ngokwanele angasekela impilo yamahomoni nokuzala.

Ngabe izingubo zangaphansi eziqinile ngempela zithinta inani lesidoda?

Ucwaningo lusekela umthelela othile wezinga lokushisa kwesikhwama sesende ekukhiqizweni kwesidoda. Ucwaningo ku-Human Reproduction lwathola ukuthi amadoda agqoka izingubo zangaphansi ezikhululekile ayenezinga eliphezulu lokugxila kwesidoda kunalawo agqoka izingubo zangaphansi eziqinile. Nokho, usayizi womphumela umncane, futhi ukugqoka izingubo zangaphansi ezikhululekile kuphela akunakwenzeka ukuthi kuxazulule izinkinga ezinkulu zokungazali — kodwa kuwushintsho olulula ongakwazi ukulwenza.

Yiziphi izinhlobo zokudla ezinhle kakhulu empilweni yesidoda?

Ukudla okuhlotshaniswa ngokungaguquki nekhwalithi engcono yesidoda kufaka phakathi ama-walnut (anothile ngama-omega-3), imifino eluhlaza emnyama (i-folate), ama-oyster namantongomane e-pumpkin (i-zinc), amaqanda namantongomane aseBrazil (i-selenium), amajikijolo nezithelo ze-citrus (ama-antioxidant), nezinhlanzi ezinamafutha (i-omega-3 DHA). Indlela yokudla yaseMedithera iyonke iyona enobufakazi obuqinile kakhulu bocwaningo mayelana nenzalo yamadoda.

Ingabe ukungabi nenzalo emadodeni kuyagobhozela emndenini (kuyifa)?

Ezinye izimbangela zokungabi nenzalo emadodeni zinezinto zofuzo. Ama-microdeletions ku-chromosome Y, i-Klinefelter syndrome (XXY), nezinye izimo zofuzo zingabangela i-azoospermia noma i-oligospermia esindayo. Izinguquko kofuzo we-cystic fibrosis zingabangela ukungabi khona kwe-vas deferens. Nokho, izimo eziningi zokungabi nenzalo emadodeni azidabangi ifa, kodwa zibangelwa izinto zemvelo, amahomoni, noma ukwakheka komzimba.

Ngabe izithasiselo zingayithuthukisa ngempela ikhwalithi yesidoda?

Yebo, izivivinyo eziningi ezilawulwa ngendlela ye-randomized controlled trials zibonisile ukuthi izithasiselo ezithile — ikakhulukazi ama-antioxidant afana ne-CoQ10, i-vitamin C, i-vitamin E, i-selenium, ne-zinc, kanye ne-L-carnitine ne-folate — zingathuthukisa izinkomba zesidoda emadodeni anekhwalithi yesidoda engaphansi kokujwayelekile. Imiphumela ivelele kakhulu emadodeni anokucindezeleka kwe-oxidative noma ukushoda kokudla okunomsoco. Ikhwalithi nomthamo wezithasiselo kubalulekile kakhulu.

Ukubhema kuthinta kanjani inzalo yamadoda?

Ukubhema kunezinto ezimbi ezaziwayo enzalweni yamadoda. Ubuthi bokubhema kubangela ukwehla kokubalwa kwesidoda cishe ngo-13–17%, kwehlise ukunyakaza, kwandise ukuma okungajwayelekile kwesidoda, futhi kudale ukulimala kwe-DNA esidodeni. Ezinye zale miphumela ziyalungiseka lapho umuntu eyeka ukubhema, ngokuthuthuka okuvame ukubonakala phakathi nezinyanga ezi-3. Nokuqothuka intuthu yabanye (secondhand smoke) nakho kunezimiphumela ezimbi eziqinisekisiwe.

Uyini umehluko phakathi kokubalwa kwesidoda nokunyakaza kwesidoda?

Ukubalwa kwesidoda kubhekisela enanini lesidoda elikhona esampulini yesidoda, kanti ukunyakaza (motility) kubhekisela kumaphesenti esidoda esinyakazayo kanye nekhwalithi yale nyakazo. Indoda ingaba nokubalwa okujwayelekile kodwa ukunyakaza okubi (asthenospermia), ukubalwa okuphansi kodwa ukunyakaza okuhle, noma inhlanganisela yalokhu. Lezi zinkomba zombili zibalulekile enzalweni, ngoba isidoda kumele sibe khona ngamanani anele futhi sikwazi ukubhukuda kahle ukuze sifinyelele futhi sichumise iqanda.

Kufanele ngiyobonana nini nodokotela mayelana nenzalo yamadoda?

Hamba uyobonana nochwepheshe wezempilo ukuze uhlolwe inzalo yamadoda uma: wena nomlingani wakho nibe nizama ukukhulelwa izinyanga ezingu-12 ningaphumeleli (izinyanga ezingu-6 uma eneminyaka engaphezu kwengu-35); unomlando wokulimala kwamaphaphu esende, ukuhlinzwa, noma izende ezingazange zehle; uke wahlonzwa ukuthi unayo i-varicocele; unazo izinkinga zamahomoni noma izofuzo ezaziwayo; noma uke wathola ukwelashwa komdlavuza phambilini. Ungalindi — ukuhlolwa kusenesikhathi kuholela ekungeneleleni kusenesikhathi nasekuphetheni okuhle kakhulu.
