Ngifuna Ukukhulelwa Kule Nyanga Amathiphu Ngokuthi Niyocansi Kangaki Namathuba

Ngezinye izikhathi sizithola sinomuzwa oqinile wokuthi, kumele ngikhulelwe kule nyanga! Lokho kungasinda engqondweni yakho, ikakhulukazi uma usunesikhathi ufisa ukuba nomntwana. Kodwa ingabe kulula njengokuthi nje nijwayele ukusondelana kakhulu? Noma mhlawumbe kukhona iqhinga eliyimfihlo abantu abalisebenzisayo? Lolu hambo lungazwakala lukhungathekisa kancane, okuyinto ejwayelekile ngokuphelele. Ake sihlole imiqondo ebalulekile, kusukela ekutheni ubona kanjani izikhathi eziphakeme zokuzala kuya ezinhlotsheni zamavithamini nezinguquko endleleni yokuphila. Sizophinde sixoxe nangokuthi kwenziwani uma uzithola uzibuza imibuzo enjengokuthi kungani ngingakhuleli noma kunzima yini ukukhulelwa ngisho noma kubonakala sengathi konke kuhamba kahle. Inhloso ukusiza ukuthi ubone ukuthi nakuba ungenakuphoqa umphumela, ungathatha izinyathelo zangempela zokwandisa amathuba akho okukhulelwa ngendlela elinganiselayo, enokuthula ngaphandle kwengcindezi enkulu.

Ukuqonda Izisekelo Zokuzala

Uma ucabanga ngokuzama ukucabanga umntwana, kubalulekile ukwazi ukuthi konke kusebenza kanjani. Umjikelezo wakho wokuya esikhathini uwona omisa inkundla. Ngokuvamile, uma umjikelezo wakho uyizinsuku ezingu-28, ukuvuthwa kwamaqanda kungase kwenzeke cishe ngosuku lwe-14, kodwa lokho kungahluka nakanjani. Lapho iqanda selikhishiwe esibelethweni, lihlala isikhathi esingangezinsuku ezingu-1 kuphela. Ngakolunye uhlangothi, isidoda singaphila esithweni sokuzala sowesifazane izinsuku ezimbalwa. Yilokho okwenza isikhathi sibaluleke kangaka. Abesifazane abaningi abakhulelwayo ngempumelelo bathola ukuthi ukuqonda ifasitela labo lokuzala nokugcina indlela yokuphila enempilo kukhuphula kakhulu amathuba abo okuqhamuka komntwana [1]. Abantu abaningi bayazibuza ukuthi kunzima kangakanani ukukhulelwa uma behlala bephuthelwa lelo fasitela lokuzala. Ukuze sikhulume iqiniso, kungase kungabi lula.

Uma imibhangqwana igxila esikhathini esiseduze nokuvuthwa kwamaqanda, ingakhuphula amathuba okukhulelwa. Kodwa lokho akusho ukuthi kuzokwenzeka ngokushesha. Ezinye izithandani zikhulelwa masinyane, okushiya abanye bezibuza, “ukukhulelwa ngomzamo wokuqala kuwuphawu oluhle yini?” Kungaba yinhlanhla noma kube ukuvumelana kwesikhathi nje. Ungesabi uma kungenzeki ngokushesha kanjalo.

Thatha ikhalenda, ubhale ubude bomjikelezo wakho, ubheke nezimpawu ezifana noshintsho emandleni obovu lwesibeletho. Uma lowo muthi usuba sobala kakhulu futhi uyeluleke, lokho ngokuvamile kuyisibonakaliso sokuvuthwa kwamaqanda. Ukulandelela izinga lokushisa lomzimba nakho kuyasiza, uma unomonde wokukwenza. Kanyekanye, zama ukugcina umqondo ovulekile, ikakhulukazi uma ubhekene nombuzo othi, kunzima yini ukukhulelwa uma impilo nengcindezi kungena phakathi.

Lingaki izikhathi okufanele nisondele ngocansi

Kujwayelekile ukuzibuza ukuthi kudingeka nilale ocansini kangaki ukuze nikhulelwe. Abanye abantu bazama ukusondelana nsuku zonke. Abanye bakwenza kube kanye noma kabili ngesonto. Akukho mthetho oyedwa oqondile. Eqinisweni, abaningi bayazibuza ukuthi ukulala ocansini nsuku zonke ukuze ukhulelwe kukhuphula amathuba abo yini. Kungakusiza, kodwa ukuzama nsuku zonke kungakhathaza abanye ozakwenu. Abanye bayakhathazeka bacabange ukuthi mhlawumbe lokho “kweqile.”

Odokotela bavame ukweluleka ukuthi ukuba nocansi njalo emasontweni amabili kuya kwamathathu kuyisu elijwayelekile elihle. Leso schedule sigcina inani le-sperm lisisha ngaphandle kokwenza izinto zibe ngumsebenzi onzima. Omunye umbuzo onzima uthi: kumele ngibe nocansi izikhathi ezingaki ukuze ngikhulelwe uma nisanda kuqala ukuzama? Ayikho inombolo eqondile. Abanye basizakala ngokuba nocansi kaningi, kanti abanye bakhetha izikhathi eziphakathi nendawo.

Uma uzizwa unamandla kakhulu, ningakwazi ukwenza njalo. Kodwa qaphelani: anifuni ukuthi ucansi lube umsebenzi owenziwa nje ngomshini. I-stress ingaphazamisa ama-hormone [2]. Kuhle futhi ukukhumbula ukuthi ithuba lokukhulelwa lixhumene nesikhathi, ngakho kungaba kuhle ukugxila kulawo maholide enu okuzala.

Nsuku Zonke Noma Ngezinsuku Ezishintshanayo?

Amabhangqa avame ukuxoxisana ngokuthi kungcono ukuba nocansi nsuku zonke noma ngezinsuku ezishintshanayo ngesikhathi sokuvundela. Abanye abantu bafuna ukulwenza nsuku zonke uma besola ukuthi i-ovulation isondelene, kodwa akuwona wonke umuntu okhululekile kulolo zinga. Kukhona nombuzo ovame ukuvela othi: ingabe ukuba nocansi nsuku zonke kubi uma nizama ukukhulelwa? Akusikho ukuthi kubi ngokuzenzakalelayo, ngoba abalingani abaningi bagcina izinga le-sperm elinempilo ngisho nangenocansi lwansuku zonke [3].

Ngakolunye uhlangothi, kukhona nendlela yokuba nocansi ngosuku olulodwa bese niphumula olunye ukuze nikhulelwe. Le ndlela ilungele labo abathola ucansi lwansuku zonke ludikibalisa noma lukhathaza. Ukuzama ukubona ukuthi iyiphi iphethini enisebenzela kahle kubalulekile. Uma nifuna nsuku zonke, kulungile. Uma ukweqa usuku kwenza wena nomlingani uzizwe nisondelene futhi ningakhathali kakhulu, lokho kungaba kuhle futhi. Iqiniso ukuthi, akukho fomula eyodwa eqinisekisa impumelelo.

Ukulandelela I-ovulation

Noma ubani obuza ukuthi “ngifanele ngibe nocansi kaningi kangakanani ukuze ngikhulelwe” udinga ukuqonda ukuthi i-ovulation yenzeka nini. Ningabheka lowo mfinyila ofana neqhanda elishaywe kahle, noma nisebenzise amakhithi okuqagela i-ovulation. Abanye abantu baphinde bakale izinga lokushisa lomzimba eliyisisekelo nsuku zonke ekuseni. Ngosuku olulandelayo ngemuva kwe-ovulation, izinga lokushisa lingakhuphuka kancane.

Kukhona nombuzo wokuthi kufanele nibe nocansi kangaki ukuze nikhulelwe, noma ukuthi kumele sibe nocansi izikhathi ezingaki ukuze sikhulelwe uma nicacisa kahle isikhathi se-ovulation. Akudingeki ukuba nibe nocansi nsuku zonke ngaphandle kokuphumula. I-sperm ingasinda izinsuku ezimbalwa [4]. Ngakho-ke uma nihlela ngesikhathi ucansi usuku olulodwa noma ezimbili ngaphambi kwe-ovulation, bese mhlawumbe naso ngosuku uqobo lwe-ovulation, amathuba enu okukhulelwa angahle abe mahle. Ningakhathazeki uma ningakwazi ukunemba ngo-100%. Imizimba ingaba nezinselelo ezingalindelekile.

Ingabe Kunzima Ukukhulelwa?

Omunye umbuzo omkhulu uthi, kungani ngingakhuleli ngisho noma nenza izinto “ezilungile”. Enye ithi, kungani ngingakhuleli uma nimisa isikhathi kahle futhi udokotela wenu ethi konke kujwayelekile. Kwamanye amabhangqa, kuthatha isikhathi nje, okungavusa umbuzo othi, kungani ngingakhuleli uma konke kubonakala kujwayelekile. Kungaba ukungalingani okuncane kwama-hormone noma izinkinga ezincane ezifihlekile ezingabanjwa kalula ukuhlolwa okuvamile.

Ngempela kunzima kangakanani ukukhulelwa? Ezinye imibhangqwana ikhulelwa zingakapheli izinyanga ezimbalwa, ezinye zingase zidinge cishe unyaka [5]. Akukho isikhathi esisodwa esisebenzayo kubo bonke. Bese uzwa abantu bebabuza, “ukukhulelwa ngomzamo wokuqala kuwuphawu oluhle lwesikhathi esizayo esinempilo yini?” Kungenzeka, kodwa kumayelana kakhulu nokuhambisana kokuzala okuphelele kunanoma yisiphi isiqinisekiso sesikhathi esizayo.

Zama ukugcina okulindelwe kungokoqobo. Imibhangqwana emaphakathi ingase ingakhuleli masinyane. Uma useneminyaka eminingi noma unokukhathazeka ngezempilo okwaziwayo, ungase ufune ukubonana nochwepheshe ngemva kwezinyanga ezimbalwa zokungaphumeleli. Ngezinye izikhathi isizathu sangempela sokungakhuleli nakuba konke kubonakala kujwayelekile singaveli kuze kube yilapho senziwa olunye ukuhlolwa. Abesifazane abafuna ukukhulelwa kufanele bagxile futhi ekugcineni indlela yokuphila enempilo, ukulandelela isikhathi sokukhishwa kweqanda, nasekuboniseni udokotela uma ukukhulelwa kuthatha isikhathi eside kunalokho obukulindele.

Ukunomsoco Nezithako Ezingase Zisekele Ukuzala

Abanye abantu bagxila kumavithamini, amaminerali, nakwezinye izinto ezingase zisize. Uzobona abantu bekhuluma kakhulu nge-folic acid, esiza ukuvimbela ezinye iziphambeko zokuzalwa futhi isize ukukhula kokuqala kombungu. Ezinye izibonelo yi-Myo-Inositol ne-D-Chiro Inositol, ezilungele abantu ababhekene nezinkinga ze-insulin noma i-PCOS. I-CoQ10 idume kakhulu futhi, ngoba iyi-antioxidant engase isize ngekhwalithi yamaqanda [6].

Siphinde sizwe kukhulunywa ngemavithamini anjenge-C, E, kanye nomndeni wonke we-B. Asiza empilweni ejwayelekile yamaseli, ekusebenzeni kwama-hormone, noma ekukhiqizeni amandla. Ujinja unganciphisa ukuvuvukala. I-iron ibalulekile ekuthwaleni umoya-mpilo egazini. I-zinc ibalulekile empilweni yesidoda, futhi isekela ibhalansi yama-hormone kuzo zombili izinhlanga. Bese kuba khona i-magnesium, esiza ekulawuleni ama-hormone, kanye ne-calcium esekela ukusebenza kwemisipha nemizwa. I-selenium inamandla e-antioxidant, kanti i-iodine isiza ukugcina i-thyroid ilawulwa. I-L-Arginine ingathuthukisa ukugeleza kwegazi, kanti i-taurine isiza ukunciphisa ukucindezeleka [7].

Izithako zemifino enjengempande ye-maca noma i-ginseng kwesinye isikhathi zifakwa kumafomula okuzala kwabesilisa ukuze kukhuliswe isifiso socansi ikhwalithi yesidoda. I-Withania Somnifera (Ashwagandha) isetshenziswa kabanzi njengomuthi wendabuko osiza umzimba ukujwayela ukucindezeleka. Futhi amafutha anempilo anjenge-DHA avela ku-fish oil angaba wusizo ekuthuthukiseni umbungu. Ngakho imibhangqwana eminingi izozama lokhu ngenhloso yokwandisa amathuba abo okukhulelwa, kodwa imiphumela iyahlukahluka.

Ukuthambisa Ngokwesekela

Uma ukoma noma ukungakhululeki kuyinkinga, ama-lubricant anobungane ekuzaleni angasiza. Amanye ama-lube athengwa esitolo awanabo ububele obufanayo kuma-sperm. Kunamafomula ane-calcium kanye nama-ion e-magnesium akhona ukusiza ukunyakaza kwama-sperm [8]. Abantu baphinde babuze ukuthi ukusebenzisa lawa ma-lube akhethekile kungase kukhuphule yini ukuthi yini amathuba okukhulelwa. Mhlawumbe kancane. Ngokuqinisekile kusiza uma ukoma bekuyisithiyo sangempela.

Qinisekisa nje ukuthi uyahlola amalebula. Umkhiqizo othi “uvumelana nokuzala” ngokuvamile usho ukuthi awunazo izibulala-zinambuzane ezinzima ezingalimaza isidoda. Uma kunzima ukujabulela ubulili, i-lube enhle ingaba usizo olukhulu, ikakhulukazi uma niphoqa ukuba nocansi nsuku zonke ukuze nikhulelwe phakathi nesikhathi senu sokuzala.

Impilo Yamadoda Ibalulekile

Kwesinye isikhathi sikhuluma kakhulu ngokuzala kwabesifazane size sikhohlwe ukuthi impilo yamadoda iyingxenye eyingxenye yalokhu. Amadoda angase abhekane nezinkinga zenani eliphansi lesidoda, ukuhamba kwesidoda okubi, noma ukuma okungajwayelekile. Lokho kungathonya ukuthi yimaphi amaphesenti okukhulelwa, ngoba uma isidoda singakwazi ukubhukuda kahle noma singenele, ukuhlanganisana kweqanda nesidoda kungaba nzima.

Izithasiselo zamadoda zingafaka i-zinc, i-selenium, i-L-carnitine, i-maca, ne-ginseng, phakathi kwezinye. Ngokuhamba kwesikhathi, le mikhiqizo yokudla ingenza umehluko. Kodwa futhi kuhlakaniphile ukwenza imikhuba enempilo njengokugwema ukubhema nokuphuza kakhulu utshwala [9]. Ukucindezeleka kungalimaza nokuzala kwabesilisa. Uma wena noma umlingani wakho nibuzana, “uma sizama ukukhulelwa kufanele sikwenze kangaki ngosuku,” khumbulani ukuthi ikhwalithi ingaba nomthelela omkhulu kunezinombolo nje.

Ukucabangela Imvamisa Nesikhathi

Umbuzo obalulekile ukuthi kufanele nibe nobulili kangaki ukuze nikhulelwe uma ningaqiniseki ngewindi lenu lokuzala. Omunye umbuzo uthi, “ngabe kufanele ngibe nocansi nsuku zonke ukuze ngikhulelwe, noma lokho kudlulele?” Abanye abantu benza ubudlelwano bocabango nsuku zonke izinsuku ezimbalwa ezizungeze isikhathi sokuya esikhathini sokuvuthwa kweqanda. Abanye bakhetha “usuku nolandelayo baphumule” ukuze isidoda sowesilisa sakhe isibalo. Bese kuba nombuzo othi, “ngabe ukuba nocansi nsuku zonke kubi yini uma nizama ukukhulelwa?” Ngokuvamile kulungile ngaphandle uma amazinga okucindezeleka enyuka noma ikhwalithi yesidoda isibonakala yehla [10].

Cabanga ngokuba njalo, kodwa ungakwenzi kube umsebenzi osindayo. Uma nihlela ukwenza ucansi nsuku zonke ukuze nikhulelwe, niqaphele indlela enizizwa ngayo ngokomzwelo nangokwenyama. Uma nobabili nikulungele, kulungile. Uma kungenjalo, mhlawumbe nijikele ekwenzeni njalo ngosuku lwesibili. Lokho kusamele kuhlanganise kahle isikhathi senu sokuzala.

Ushintsho Lwendlela Yokuphila Olusiza Ukukhulelwa

Indlela ophila ngayo ibaluleke kakhulu kunalokho abaningi abakubona. Ukukhuluphala ngokweqile noma ukuncipha ngokweqile kungaphazamisa amahormone. Ukuphuza kakhulu utshwala nokubhema nakho kwakha izithiyo ezinkulu ekuzaleni. Ngakho akumangalisi ukuthi imibhangqwana eminingi ebuzayo mayelana nokuthi yiziphi izibalo zokukhulelwa ingase idinge ukulungisa indlela adla ngayo noma imikhuba yawo yansuku zonke.

Ukucindezeleka, okuyinto ehlekisayo, kunganciphisa ukuzala kakhulu. Abanye abantu bayabuza, “kungani ngingakhulelwa noma zonke izivivinyo zibonakala zijwayelekile?” Kwesinye isikhathi udinga nje ukuphumula kangcono, noma ungase ufune ukunciphisa ukuzivocavoca okunzima kakhulu [11]. Uma ugcina ibhalansi, umjikelezo wakho ungaba lula ukuwuqagela, kanjalo nenani lesidoda likapartner wakho. Lokho kungakhulisa amathuba okukhulelwa ngokuhamba kwesikhathi.

Izizathu Ezingaba Khona Zokubambezeleka

Ngakho uma ungakwazi ukukhulelwa, noma uqhubeka ubuza ukuthi, “kungani kunzima kangaka ukukhulelwa?” noma “kungani ngingakhuleli nakuba konke kujwayelekile?” ungacabangi ukuthi wenza okuthile okungalungile. Ukungazali kungadalwa izizathu ezincane, njengokungalingani okuncane kwe-thyroid noma ukuvinjelwa kwamapayipi ama-fallopian. Amadoda nawo angaba yimbangela cishe ezimweni ezingaba yisikamu sesigamu.

Isizathu sokungakhuleli nakuba konke kubonakala kujwayelekile kwesinye isikhathi singaba izinkinga ezincane zesikhathi. Enye into engaba nomthelela kungaba yi-endometriosis elula noma nama-fibroid esibeletho angakabonwa muntu. Noma mhlawumbe uke waba nokukhulelwa okuthiwa “chemical pregnancies” okuphele ngaphambi kokuba uqaphele nokuthi uke wakhulelwa [12].

Okubalulekile Ekugcineni

Lapho lokho kuphuthuma kokuthi “kufanele ngikhulelwe kule nyanga” kuvela, kulula ukuzizwa ucindezelekile. Kodwa khumbula ukuthi umzamo oqhubekayo, ukubekezela okuncane, nokuzinakekela ngendlela elinganiselayo kuvame ukukhokha esikhathini eside. Uma uqhubeka uzibuza ukuthi “kungani ngingakwazi ukukhulelwa” noma “kungani kunzima kangaka ukukhulelwa”, cabanga ukuya kudokotela noma umhlinzeki wezempilo ukuze kuhlolwe ukuthi azikho yini izinkinga ezifihlekile.

Ezimweni eziningi, isikhathi esifanele, ingcosana yokuphila okunempilo, mhlawumbe namanye amavithamini nezakhamzimba ezisekela ukuzala, kungakhulisa amathuba akho okukhulelwa [13]. Lokho kuyingxenye yobuhle balokhu. Ungahlola izinguquko, ubone ukuthi umzimba wakho uphendula kanjani, bese uthola ukuthi yini ongayigcina isikhathi eside. Ekugcineni, lolu hlelo lwakho lungakusiza ufinyelele kuleyo mpumelelo emnandi ubuyifisayo, ngenkathi ugcina nengcindezi ilawulwa. Ukuqonda okubangela ukukhulelwa nakho kungadlala indima ebalulekile ekwenzeni izinqumo ezinolwazi nasekuthuthukiseni ukukwazi ukuzuza ukukhulelwa

Imibuzo Evame Ukubuzwa

Ingabe ukuba nocansi nsuku zonke kwehlisa inani lesidoda?

Ezinye amadoda abonakala ehla kancane inani lesidoda uma ekhishwa izikhathi eziningi ngosuku, kodwa kanye ngosuku imvamisa akuyona inkinga enkulu. Kodwa umzimba womuntu ngamunye uhlukile.

Ingabe amavithamini angangisiza ngikhulelwe ngokushesha?

Kungenzeka. I-folic acid, insimbi, i-zinc, i-CoQ10 nezinye zingase zisekele impilo yokuzala. Kodwa azilona ikhambi lomlingo. Ukudla okunempilo nokuziphatha kahle empilweni kusabalulekile kakhulu.

Ingabe abashadile kufanele bahlale benocansi ngalo lona kanye usuku lokuvuthwa kwamaqanda?

Ukusondela ngosuku lokuvuthwa kwamaqanda (ovulation) kuyisikahle, kodwa isidoda singaphila izinsuku ezimbalwa. Uma nilala ndawonye usuku olulodwa noma amabili ngaphambi kokuvuthwa kwamaqanda, lokho kungase kwanele. Asikho isidingo sokulinda usuku olunembile olulodwa kuphela.

Kufanele ngizame imijikelezo emingaki ngaphambi kokuba ngiqale ukukhathazeka ngokungazali?

Izeluleko ezijwayelekile ziphakamisa ukuthi kungathatha cishe unyaka uma uneminyaka engaphansi kwengu-35, kanti mhlawumbe izinyanga eziyisithupha uma ukhulile. Kulungile ukuya kudokotela masinyane uma ukhathazekile.
