Sifaka imikhiqizo esicabanga ukuthi ilusizo kubafundi bethu. Uma uthenga ngezixhumanisi ezikuleli khasi, singathola ikhomishini encane. Nansi inqubo yethu.

Kungenzeka ukuthi uzwile ukuthi amathuba okukhulelwa umfana noma intombazane cishe angama-50-50. Kepha wake wazibuza ukuthi kungenzeka yini ukuthonye izingqinamba uma kukhulunywa ngobulili bengane yakho?

Kungenzeka - futhi kukhona isayensi ethile yokusekela lo mbono. Eminye imibhangqwana ifunga ngalokho okubizwa ngokuthi indlela kaShettles. Le ndlela ichaza imininingwane nini futhi Kanjani ukwenza ucansi ukuze ukhulelwe umfana noma intombazane.

Ake singene kulo mbono!

Yini indlela kaShettles?

Indlela kaShettles ibilokhu ikhona kusukela ngawo-1960. Yakhiwa nguLandrum B. Shettles, udokotela ohlala e-United States.

UShettles wafunda isidoda, isikhathi sokuya ocansini, nezinye izinto, njengesimo sobulili kanye ne-pH yeziphuzo zomzimba, ukuthola ukuthi yini engaba nomthelela lapho isidoda sifinyelela eqandeni kuqala. Ngemuva kwakho konke, isidoda esivundisa iqanda ekugcineni yilokho okunquma ubulili bengane. (Okuningi ngaleyo nqubo ngomzuzu.)

Kusuka ocwaningweni lwakhe, uShettles wasungula indlela ebheka zonke lezi zinto. Njengoba ungacabanga, lolu lwazi beludingeka kakhulu. Ngakho-ke, uma ungathanda ukufundwa okujulile, ungacabanga ukuthatha incwadi kaShettles ethi “How to Select the Sex of Your Baby,” eyagcina ukubuyekezwa yabuyekezwa ngo-2006.

Lunqunywa kanjani ucansi ngesikhathi sokukhulelwa

Ubulili bengane yakho bunqunywa ngendlela eyisisekelo kakhulu ngesikhathi lapho isidoda sihlangana neqanda. Amaqanda omfazi afakwa ngezakhi zofuzo ne-X chromosome yesifazane. Ngakolunye uhlangothi, abesilisa bakhiqiza izigidi zesidoda ngesikhathi sokuchama. Cishe uhhafu walesi sidoda ungabhalwa nge-X chromosome ngenkathi enye ingxenye iphethe i-chromosome Y.

Uma isidoda esivundisa iqanda siphethe i-chromosome ye-Y, umntwana ovelayo kungenzeka azuze i-XY, esiyihlobanisa nokuba ngumfana. Uma isidoda esivundisa iqanda siphethe i-X chromosome, umntwana ovelayo kungenzeka azuze ifa le-XX, okusho ukuthi intombazane.

Vele lokhu kuncike ekuqondeni okujwayelekile kakhulu kokuthi luyini ucansi nokuthi luchazwa kanjani.

Isilisa nesilisa isidoda

UShettles wafundela amangqamuzana wesilisa ukuze abone umehluko wabo. Lokho akucabangayo ngokususelwa ekuboneni kwakhe ukuthi isidoda sikaY (owesilisa) silula, sincane, futhi sinamakhanda ayindilinga. Ehlangothini le-flip, isidoda se-X (esifazane) sinzima, sikhulu, futhi sinamakhanda amise okweqanda.

Kuyathakazelisa ukuthi futhi wafunda isidoda kwezinye izimo ezingavamile lapho abesilisa babezala ikakhulu izingane zesilisa noma ikakhulukazi zabesifazane. Ezimweni lapho amadoda ayenezingane eziningi zesilisa, uShettles wathola ukuthi la madoda ayenesidoda esingaphezu kwesingu-X kunesidoda esingu-X. Futhi okuphambene nakho kuzwakale kuyiqiniso emadodeni abenezingane ikakhulukazi zabesifazane.

Izimo ezinhle zabafana / zamantombazane

Ngaphezu kokwehluka ngokomzimba, uShettles wayekholelwa ukuthi isidoda sowesilisa sivame ukubhukuda ngokushesha ezindaweni ezinama-alkaline, njengasesizalweni somlomo wesibeletho nasesizalweni. Futhi isidoda sowesifazane sithambekele ekusindeni isikhathi eside ezimeni ezine-asidi zomsele wesitho sangasese sowesifazane.

Njengomphumela, indlela yangempela yokukhulelwa intombazane noma umfana ngendlela yeShettles ichazwa yisikhathi nezimo zemvelo ezisiza ukuthanda isidoda sowesilisa noma sowesifazane.

Ungazama kanjani umfana onendlela kaShettles

Ngokusho kukaShettles, ukwenza ucansi ngesikhathi esiseduze noma ngemuva kokuvuthwa kuyisihluthulelo sokwenza umfana. UShettles uchaza ukuthi imibhangqwana efuna umfana kufanele igweme ukuya ocansini phakathi kwesikhathi sakho sokuya esikhathini nezinsuku ngaphambi kokukhulelwa kweqanda. Esikhundleni salokho, kufanele wenze ucansi ngalo kanye usuku lokuvuthwa futhi kufika ezinsukwini ezimbili kuya kwezi-3 ngemuva kwalokho.

Le ndlela ithi indawo ekahle yokukhulelwa umfana kungenye evumela ukuthi isidoda sifakwe eduze nomlomo wesibeletho ngangokunokwenzeka. Isikhundla esiphakanyiswe nguShettles singesowesifazane ofakwa ngemuva, okuvumela ukungena okujulile.

I-Douching ngesinye isiphakamiso esenziwe nguShettles. Njengoba umbono uthi isidoda sowesilisa njengendawo ene-alkaline ethe xaxa, ukunambitha ngezipuni ezimbili zesoda yokubhaka exutshwe nelitha elilodwa lamanzi kungasebenza. Kodwa-ke, uShettles uchaza ukuthi amadokodo kudingeka asetshenziswe ngaphambi kocansi ngalunye nesikhathi.

Khuluma nodokotela wakho ngaphambi kokuzama ukukhipha i-douching, njengoba kuvame ukwenziwa odokotela abaningi kanye ne-American College of Obstetricians and Gynecologists. Ukuchofoza kungashintsha ibhalansi yezitshalo esithweni sangasese futhi kuholele ekutheleleni. Kungase kuholele nasezindabeni ezibucayi kakhulu zezempilo, njengesifo sokuvuvukala okhalweni, okuyinkinga yayo yokungazali.

Ngisho nesikhathi se-orgasm kuyacatshangelwa. NgoShettles, imibhangqwana iyakhuthazwa ukuthi ibe ne-orgasm yowesifazane kuqala. Kungani kunendaba lokhu? Konke kubuyela emuva ku-alkalinity.

Isidoda ngokwemvelo sine-alkaline ngokwengeziwe kunemvelo ene-esidi yowesifazane. Ngakho-ke, uma owesifazane eqala ukugcwala ubuthakathaka bomqondo, umqondo ukuthi uketshezi lwakhe luyi-alkaline ethe xaxa futhi kungasiza isidoda sowesilisa ukubhukuda siye eqandeni.

Ungazama kanjani intombazane ngendlela yeShettles

Ukuthungatha intombazane? Iseluleko ngokuyisisekelo siphambene.

Ukuzama intombazane, uShettles uthi isikhathi sokuya ocansini ekuqaleni komjikelezo wokuya esikhathini futhi uyeke ezinsukwini ngokushesha ngaphambi nangemva kokuvuthwa. Lokhu kusho ukuthi imibhangqwana kufanele iye ocansini kuqala ezinsukwini ngemuva kokuya esikhathini bese iyeka okungenani izinsuku ezintathu ngaphambi kokukhulelwa kweqanda.

Ngokusho kukaShettles, isikhundla sobulili esihle kakhulu sokukhulelwa kwentombazane yiso esivumela ukungena okungajulile. Lokhu kusho ukuthi ucansi lobufundisi noma lobuso nobuso, uShettles athi luzokwenza isidoda ukuthi sihambele kude kakhulu endaweni enesitho sangasese sowesifazane, sithande isidoda sowesifazane.

Ukwengeza i-asidi eyengeziwe ku-equation futhi uthande isidoda sowesifazane, uShettles uphakamisa idokodo elenziwe ngezipuni ezimbili zoviniga omhlophe kanye nelitha elilodwa lamanzi lingasetshenziswa. Futhi, i-douche kufanele isetshenziswe njalo lapho izithandani ziya ocansini ukuze ziphumelele kakhulu. (Futhi, khuluma nodokotela wakho ngaphambi kokuzama le douche ethile.)

Kuthiwani nge-orgasm? Ukugwema ukufaka ukwengeza okungaphezulu emvelweni, le ndlela iphakamisa ukuthi owesifazane kufanele azame ukuyeka i-orgasm kuze kube yilapho owesilisa esekhiphile.

Ingabe indlela kaShettles iyasebenza?

Ungathola abantu abaningi abazothi le ndlela ibasebenzele, kepha ingabe isayensi iyakusekela lokho?

I-Blogger Genevieve Howland kuMama Natural ungomunye othi indlela kaShettles imsizile wakwazi ukuthinta intombazane ekhulelwe okwesibili. Yena nomyeni wakhe babeka isikhathi ocansini ezinsukwini ezintathu ngaphambi kokuvuthwa futhi ukukhulelwa kwaholela entombazaneni. Uchaza ngokuqhubekayo ukuthi ngokukhulelwa kwakhe kokuqala, baya ocansini khona kanye ngosuku lokuvuthwa, okwaholela ekubeni umfana.

Leli cala elilodwa lifundela eceleni, uShettles ubanga inani lokuphumelela elingamaphesenti angama-75 kuhlelo lwamanje lwencwadi yakhe.

Akubona bonke abacwaningi abavumayo ukuthi izinto zigundiwe futhi zomile, noma kunjalo.

Eqinisweni, ukuphikisa okushiwo nguShettles. Kulezo zifundo, abacwaningi babheka nesikhathi sokuya ocansini, kanye nezimpawu zokuvuthwa, njengokushisa komzimba okuyisisekelo kanye nokuphakama komlomo wesibeletho.

Ucwaningo luphethe ngokuthi zimbalwa izingane zesilisa ezakhulelwa ngesikhathi sokuphakama kwe-ovulation. Esikhundleni salokho, izingane zesilisa zazivame ukukhulelwa “ngokweqile” ezinsukwini ezi-3 kuye kwezi-4 ngaphambili futhi kwezinye izimo ezinsukwini ezimbili kuya kwezi-3 ngemuva kokukhulelwa kweqanda.

Okwakamuva kakhulu kuwuphikisa umqondo wokuthi isidoda esiqukethe u-X no-Y sakhiwe ngokuhlukile, okuphikisana ngqo nocwaningo lukaShettles. Futhi isifundo esidala esivela ku-1995 sichaza ukuthi ukuya ocansini ezinsukwini ezi-2 noma ezi-3 ngemuva kwe-ovulation akuholeli ekukhulelweni nhlobo.

Isayensi ayifani kahle lapha. Njengamanje, ukuphela kwendlela eqinisekisiwe yokukhetha ubulili bengane yakho kungukuxilongwa kwe-preimplantation genetic (PGD), isivivinyo kwesinye isikhathi esenziwa njengengxenye yemijikelezo ye-in vitro fertilization (IVF).

Ukudla okudlela endlini

Uma ufuna ukukhulelwa, ochwepheshe bancoma ukuya ocansini nsuku zonke kuze kufike ezinsukwini ezithile, ikakhulukazi ngokuzungeza i-ovulation. Yenza i-aphoyintimenti nodokotela wakho uma imizamo yakho ingabangeli ukukhulelwa ngemuva konyaka (ngokushesha uma uneminyaka engaphezu kwengama-35).

Uma ngabe inhliziyo yakho ihleli entombazaneni noma kumfana, ukuzama indlela kaShettles ngeke kulimaze - kepha kungenza inqubo yokukhulelwa ithathe isikhathi eside. Kuzodingeka uhambisane nesikhathi lapho ukhipha amaqanda futhi - okubaluleke kakhulu - ukuthi uzilungiselele ngokwengqondo uma imizamo yakho ingapheli emphumeleni wakho owufunayo.
