Ukwangoku, kukho iindlela ezininzi zokucwangcisa ngesondo somntwana ongakazalwa. Ukuphumelela kwabo kwahluke, njengokuba liye laphuhliswa. Phakathi kwazo zonke iinjongo zenzululwazi yindlela yokucwangcisa ngesondo lomntwana ngokunyusa. Kubalwa kweentsuku ezifanelekileyo kakhulu kunye neemeko zokukhulelwa komntwana wesini esinye okanye esinye.
Indlela yokuqhawula ngesondo lomntwana ngokukhupha isifo ngenxa yeL. Schettles kunye no-D. Rorvik, kwaye siya kuqwalasela ngokubanzi.
Yintoni ebonisa isondo somntwana?
Ubulili bomntwana ongakazalwa luxhomekeke kwisethi ye-chromosome ye-spermatozoon, eyayiyokuqala ukufikelela kwi-ovum. Ukuba bekuyi-spermatozoon ene-X-chromosome, kuya kuba nentombazana, kwaye ukuba nge-Y-chromosome, ngaba abazali baya kumnceda umntwana. Ulwazi lweli qiniso lwenza ukuba izazinzulu zijongene nombandela wokucwangcisa ngesini lomntwana. Ngokutsho kwengcamango yabo, kukho izinto ezininzi ezingekho ngqo, ukuqwalaselwa kwexesha lokunyuka kwexesha kuya kunceda ukubala isondo somntwana ongakazalwa.
Kwizinto ezinjalo, izazinzulu ezivela kwi-American Institute zithi:
- ukuphendulwa kwendawo yokulala;
- i-motility ye spermatozoa.
Kwakhona, ithuba lokukhulelwa komntwana wesondo olufunayo landa kunye nokusetyenziswa kweziganeko ezithile ngexesha lesini.
Indlela yokukhulelwa yinkwenkwe?
I-Spermatozoa kunye neesethi zeendlu zezilwanyana zithe xaxa xa zithelekiswa ne "X-abazalwana". Eyona nto ikhululekile kunye nabo kwindawo ye-alkaline yesini, ngelixa kuphendulwa kwe-asidi yendalo kukufa ngokukhawuleza. Ukwandisa amathuba okubonakala kwinkwenkwe, unokwenza ngesondo ngosuku olunye okanye ngomhla we-ovulation. Kuyacetyiswa ukuba usebenzise iziphumo kunye nokungena ngokujulileyo kwipenisi kwisini.
Indlela yokukhulelwa intombazana?
Ukucwangcisa abazali bomntwana ngeendlela zesibalo zokubala i-ovulation, kubandakanya ukulala ngesibini okanye iintsuku ezintathu ngaphambi kokukhululwa kweqanda. I-sperm mobile spermatozoa kunye ne-X i-chromosomes inokusebenza ngakumbi kuneeseli ezineethikromosomes ze-Y. Kunikezelwe ukuba ukunyameka ngexesha lokulala ngesithunywa sevangeli, amathuba okubonakalisa intombazana aphezulu. Kuyinto enqwenelekayo ukuba ibhinqa ayinakufumana i-orgasm, kuba emva kwayo impendulo yendalo yelungu ishintshela ku-alkaline.
Inkcazo ye-ovulation
Qinisekisa ukuba iintsuku ze-ovulation zingabonwa ngokugqithisileyo ngumfazi kwiqondo lokushisa elisezantsi lomzimba wakhe ngeenyanga eziliqela. Xa i-ovulation ivela, iqondo lokushisa liphakama ukuya kuma-37 degrees.
Ukuqwalaselwa kweenguqu kwiqondo lokushisa kwiinyanga eziliqela kunokunika umfanekiso ochanekileyo wokuqalisa ukuhamba. Ukongezelela, ungasebenzisa iimvavanyo ezizodwa ukucacisa i-ovulation.
Ukubeka iliso rhoqo kunokunceda ukuba uqulunqe ikhalenda yakho ye-ovulation, ngokubhekiselele kuyo ukuba ucwangcise ngesondo lomntwana. Kufuneka kukhunjulwe ukuba le ndlela ayihambelani nokuthembeka ngama-100%, kuba ifanelekile ukujikeleza kwesigxina nesigxina. Umngcipheko wokutshintshwa kwezinto ukhona kule miba, kubangelwa zizixinzelelo nezifo.
