Indlela ye-Symptothermal: Ukuqinisekisa Izinketho Zokuzala

Uhlelo lokuhlela umndeni olwemvelo seluthole intshisekelo futhi eminyakeni yamuva njengoba abashadile befuna ukuqonda indlela imijikelezo yabo yokuzala esebenza ngayo ngendlela engeyona ehlanganisa ukungenelela kakhulu emzimbeni futhi ebheka umuntu wonke. Phakathi kwezindlela ezihlukahlukene zokuqaphela ukuzala, kukhona indlela eyodwa evelele ngenxa yokuhlanganisa izimpawu zomzimba nolwazi oluqhamuka ekuzibhekeni nsuku zonke. Eyaziwa kabanzi ngokuthi indlela ye-symptothermal, inikeza indlela yokulinganisa iwindi lokuzala kowesifazane ngokuhlanganisa ukuhlola izinga lokushisa nsuku zonke, uketshezi lomlomo wesibeletho nezinye izimpawu zomzimba. 

Njengengxenye yohlelo olubanzi lokusebenzisa ukuhlela umndeni, indlela ye-symptothermal inika amandla abantu ukuthi benze izinqumo ezaziwayo mayelana nokuzala ngokuba baqonde izimpawu zabo zemvelo zokuzala. Ngezansi kunencazelo ejulile yokuthi le ndlela isebenza kanjani, isayensi ithi yini ngokusebenza kwayo, nezinto ezisemqoka okufanele zicatshangelwe yilabo abacabanga ukusebenzisa le ndlela.

Umsuka Nokuguquka Kwendlela Ehlanganisiwe

Ngokomlando, ukuqaphela ukuzala kwakuvame ukuhlotshaniswa nendlela ye-rhythm, eyayincike ekubaleni ubude bemijikelezo emaphakathi. Kodwa-ke, indlela ye-rhythm yodwa kwesinye isikhathi yayiletha ukungaqondakali ngoba imijikelezo yokuya esikhathini ingahluka kakhulu ngenxa yokucindezeleka, ukugula, nezinye izinto zokuphila. Ososayensi nochwepheshe bezempilo baqala-ke ukufuna izimpawu ezithembekile kakhulu zokukhomba i-ovulation. Ngokuhamba kwesikhathi, izinkomba ezithile ezifana nezinga lokushisa eliyisisekelo lomzimba (BBT) nokuba nokungaguquguquki koketshezi lomlomo wesibeletho zafundwa kakhulu, kwaholela ekwakhekeni kwendlela enezinhlangothi eziningi ehlanganisa lezi zinsika zombili. Ngokuhlanganisa lezi zimfanelo nokucharta njalo imijikelezo, abashadile bathola ukuqonda okunembile kakhulu kwalezo zinsuku ezimbalwa emjikelezweni lapho ukukhulelwa kungenzeka khona kakhulu.

Ubuchwepheshe besimanje nenqubekela phambili yesayensi kuthuthukise kakhulu lolu hlelo oluhlanganisiwe. Ama-app namathuluzi edijithali manje avumela abasebenzisi ukuthi bafake izilinganiso zabo zansuku zonke kuma-smartphone, akhiqize izibikezelo zokuzala ezizenzakalelayo. Naphezu kwalezi zinto ezintsha ezenza impilo ibe lula, umgomo oyisisekelo uhlala ufana: ukubheka izimpawu zomzimba ukuze kuqondwe ukuthi i-ovulation kungenzeka nini. Lokhu kugxila ezimpawini zomzimba zangempela ngesikhathi esenzeka khona kwenza le ndlela yehluke kunezindlela zangaphambilini ezazincike kakhulu emijikelezweni emide emaphakathi [1].

Isayensi Esemazingeni Eshintsha Kwezinga Lokushisa

Esinye sezinto eziyisisekelo zale ndlela ukuqapha izinga lokushisa eliyisisekelo lomzimba lowesifazane. Umzimba ngokuvamile uba nokukhuphuka okuncane kwezinga lokushisa—kusukela ku-0.2°F kuya ku-0.5°F (cishe u-0.1°C kuya ku-0.3°C)—ngemuva nje kwe-ovulation. Lokhu kukhuphuka kuhlotshaniswa ne-hormone ebizwa nge-progesterone, ekhishwa yi-corpus luteum ngemuva kokukhishwa kweqanda. Ngokuthatha njalo izinga lokushisa ekuseni njalo lapho evuka (ngaphambi kwanoma yimuphi umsebenzi), abesifazane bangabona iphethini yamazinga okushisa aphansi engxenyeni yokuqala yomjikelezo kanye nezinga eliphezulu ngemuva kwe-ovulation.

Ukunemba kuncike ekungashintshi nasekunembeni. Kubalulekile ukusebenzisa i-thermometer elinganisa okungenani kuya kumadesimali amabili (isb., 97.45°F kunokuthi 97.4°F). Ukulala okuphazamisekile, ukuwela izifunda zesikhathi ezahlukene, nokuphuza utshwala konke kungathinta izinga lokushisa lasekuseni, ngakho abasebenzisa le ndlela kudingeka babale lezi zinto lapho behlaziya amachati. Lokhu kunakwa emininingwaneni kunika abashadile amandla okuqinisekisa izinsuku ze-ovulation ngokunembe kakhulu kunokuthembela emijikelezweni yomlando kuphela [2].

Uketshezi Lomlomo Wesibeletho Nendima Yalo Ebucayi

Kubaluleke ngokulinganayo ukuqapha uketshezi lomlomo wesibeletho, olushintsha ngobunono, umbala, nobuningi phakathi nomjikelezo wokuyeka esikhathini kowesifazane. Ekuqaleni komjikelezo, ngemuva kokuya esikhathini, abaningi bazwa umswakama omncane noma ukungabi bikho koketshezi. Njengoba amazinga e-estrogen enyuka ngaphambi kwe-ovulation, uketshezi lomlomo wesibeletho kuvame ukubonakala kucacile, kudonseke, futhi kuningi. Lokhu kufana neqanda elimhlophe kusiza ekusindeni nasekufudukeni kwesidoda, kuhambisana newindi lokuzala eliphakeme. Ngemuva kwe-ovulation, ukwanda kwe-progesterone kuvame ukwenza uketshezi lwakheke kakhulu, lunamathele, noma lunciphe ngokusobala.

Lezi zimpawu ziwusizo kakhulu ngoba uketshezi lomlomo wesibeletho kwesinye isikhathi lunikeza izimpawu zangaphambi kokufika kokuzala ngaphambi kokuthi kube nezinguquko ezinkulu kwezinga lokushisa eliyisisekelo lomzimba. Ngokuhlanganisa le miphumela nokulinganisa kwezinga lokushisa ekuseni, abasebenzisi bakha isithombe esibanzi sezinsuku zokuzala zomjikelezo. Lokhu kuqinisekiswa okuphindwe kabili—iphethini elikhomba uketshezi lomlomo wesibeletho esezingeni lokuzala eliphezulu elandelwa ukwenyuka kwezinga lokushisa—kunikeza ukuzethemba okukhulu ngesimo se-ovulation kunokuhlola uphawu olulodwa kuphela [3].

Ukucharta Nokuhumusha Imininingwane

Ukugcina amarekhodi anembile ansuku zonke kusemqoka endleleni ye-symptothermal. Ishadi elijwayelekile lifaka amakholomu osuku, isikhathi sokuvuka, izinga lokushisa eliyisisekelo lomzimba, ukubonwa koketshezi lomlomo wesibeletho, nanoma yiziphi izincazelo ezengeziwe (ezifana nokuphazamiseka kokulala, izigameko zokucindezeleka, noma ukugula). Ngokuzijwayeza okuqhubekayo, kuvela amaphethini. Ngokwesibonelo, uma owesifazane ebona uketshezi lomlomo wesibeletho lwezinga lokuzala izinsuku ezintathu bese kuba nokwenyuka okucacile kwezinga lokushisa ngosuku lwesine, angamaka ukuthi i-ovulation kungenzeka yenzeke ngaphambi nje kokwenyuka kwezinga lokushisa.

Ukuthola amafasitela wokuzala kuwuhlelo olunamazinga amaningi. Amachati asiza ukubona ukuthi yiziphi izinsuku ezidinga ukungayi ocansini noma ukusebenzisa ezinye izindlela zokuvikela uma kugwenywa ukukhulelwa. Ngokuphambene nalokho, abashadile abafuna ukukhulelwa bangagxila ikakhulukazi kulezo zinsuku ezibonisa uketshezi lomlomo wesibeletho lwezinga eliphezulu ngaphambi kokwenyuka kwezinga lokushisa okurekhodiwe. Ngale ndlela, indlela ye-symptothermal inendima ephindwe kabili: ingaqondisa ukufezeka kokukhulelwa noma ukuvimbela ukukhulelwa.

Amazinga Okusebenza Nobufakazi Besayensi

Uma isetshenziswa kahle futhi njalo, ucwaningo lubonise ukuthi izindlela ezisekelwe ekuqapheliseni ukuzala zingaba nokusebenza kahle okufana nezinye izindlela zokuvimbela ezibekela umgoqo. Ucwaningo olubuyekeziwe olushicilelwe ku-Human Reproduction Update lubonise ukuthi izinhlobo ezithuthukile zokulandelela ukuzala, kuhlanganise nokuhlanganisa izinga lokushisa nokubhekwa koketshezi lomlomo wesibeletho, zingaba nezinga lempumelelo elingaphezu kuka-95% uma kusetshenziswa ngokuphelele ngendlela efanele. Ukusetshenziswa okuvamile kungase kube nesilinganiso esiphezulu sokwehluleka, kodwa imfundo nemiyalelo ecacile kuthuthukisa kakhulu ukuthembeka.

Ukuguquguquka kwale ndlela nakho kuyenza ibehehayo. Abanye abashadile bakhetha ukufunda ngaphansi kokuqondiswa ngumqeqeshi oqinisekisiwe ezinyangeni zokuqala, ukuze baqiniseke ukuthi bahumusha kahle amachati. Abanye bakhetha ukuzifundisa ngokwabo ngezincwadi ezithembekile nezifundo eziku-inthanethi, bethembele kubuchwepheshe bokurekhoda imininingwane. Noma iyiphi indlela yokufunda ekhethiwe, into ehlanganisayo ukuthi ukuzimisela ekulandeleleni nasekucharteni kuhlobene kakhulu nemiphumela emihle.

Kwabantu abafuna ezinye izindlela zokuhlela umndeni ezingenawo ama-hormone, ukuhlola i-natural plan B kunganikeza olunye uqiniso ezimeni lapho izindlela eziyinhloko zokulandelela ukuzala zidinga isu eliyisipele.

Ngale Kokuvimbela Ukukhulelwa: Iminye Imibono Yezempilo

Nakuba kuvame ukuxoxwa ngayo ikakhulukazi njengendlela yemvelo yokuhlela umndeni, indlela ye-symptothermal iphinde inikeze imininingwane ebalulekile mayelana nempilo yokuzala kowesifazane. Ukulandelela amaphethini ezinga lokushisa eliyisisekelo lomzimba kungaveza ukungajwayelekile njengengxenye ye-luteal emfushane noma i-ovulation ehlehlayo njalo. Lokhu kungajwayelekile kungase kukhombise ukungalingani kwama-hormone noma izifo ezifana ne-polycystic ovary syndrome (PCOS). Ngokwesibonelo, izinga lokushisa elihlala liphansi lingase libonise inkinga ye-thyroid, okungase kudinge ukuhlolwa okwengeziwe.

Ngokufanayo, izinguquko koketshezi lomlomo wesibeletho ezingafani nephethini elivele lamiswa zingase zikhombise ukutheleleka okungenzeka noma ukuphazamiseka komjikelezo okuhlotshaniswa nokucindezeleka. Ukubona kusenesikhathi lezi zimpawu kungakhuthaza ukushesha ukubonana nochwepheshe bezempilo, okwenza ukwenza ukuqaphela ukuzala kube wuhlobo olulula lokugada impilo kanye nendima yalo ekuvimbeleni noma ekukhonzeni ukukhulelwa [4].

Okubalulekile Ekugcineni

Noma isetshenziselwa ukukhulisa amathuba okukhulelwa noma ukuvimbela ukukhulelwa ngaphandle kokungenelela kwama-hormone, indlela ye-symptothermal imele inhlanganisela emangalisayo phakathi kwe-physiology nokuzazi. Impumelelo yayo incike kakhulu ekurekhodeni ngokuzimisela izinga lokushisa eliyisisekelo lomzimba, ukubheka uketshezi lomlomo wesibeletho, nasekuhumusheni njalo le datha. Kulabo abazimisele ukutshala isikhathi ekufundeni nasekusebenziseni le ndlela, imivuzo ingahlanganisa ukuqonda okujulile kwempilo yokuzala, ukuthuthuka kokuxhumana nomlingani, nomuzwa omkhulu wokuba negunya ngezempilo yomuntu. Ekugcineni, indlela ye-symptothermal ikhombisa ukuthi ulwazi ngemijikelezo yomzimba lungakha kanjani izinqumo ezaziyo mayelana nokuzala.
