Isibini esitshatileyo silindele ukuzalwa komntwana, amaphupha kuphela yokuba umntwana wabo unempilo. Kodwa ke, akalilahli iinzame zokusebenzisa zonke iindlela ezikhoyo zokumelana ngesondo lomntwana. Ziquka: kubalwa ngomhla wokuvuthwa kwegazi, ngexesha lokuvuselelwa kwegazi, ngexesha lokukhulelwa kunye nokukhethwa kwondlo. Siya kuqhelana nekhalenda ye-ovulation, kunye nendlela yokubala ngesondo somntwana.
Ukuxeliswa kwezesondo zomntwana ngomhla wokugqithisa
Bala i-ovulation yobundlobongela bomntwana ingaba lula ngokwaneleyo ukuba uyayazi iimpawu zomzimba zesidoda - ubuninzi besidoda esinalo kwi-chromosomal yayo ye-X okanye ye-Y-chromosome, ebonisa isondo somntwana. Ngoko, iqanda liqulethe i-X-chromosome kuphela, kunye nokudibanisa ne-sperm ene-chromosome yesondo efanayo, iya kuba ngumntwana wesisu. Ngaloo ndlela, xa iqanda lidibaniswa ne-Y-chromosome, i-fetus yowesilisa iya kubumba.
I-Spermatozoa kunye ne-X-chromosome ayisebenzi kwaye ikwazi ukusebenza ngokuphezulu. Ngoko, banako ukuhlala kwibhola ye-fallopian ukuya kwiintsuku ezingama-7 ngokulindela ukuchumisa. I-Y-spermatozoies, ngokuchaseneyo, inokuphakama okuphezulu kunye nokusebenza okuphantsi (kwimfihlo ye-alkaline yangasese bangaphila kwiintsuku ezi-2 ngaphambi kokuvuthwa kwe-ovulation).
Ngoko ke, ukuba ukukhulelwa kwenzeka emva kokugqithisa, ngoko isondo lomntwana lunokwenzeka ukuba lube yindoda. Kwaye ukuba ukulala ngesondo kungakhuselekanga kwenzeke ngaphezu kweentsuku ezine-4 ngaphambi kokuvuthwa, i-spermatozoids iya kufa ngelixesha lokuvuthwa, kwaye ukuchumisa kuya kubakho njenge-X-spermatozoon, echaza ukukhulelwa kwentombazana.
Chaza i-ovulation ukubala isondo somntwana ongakazalwa, ngeendlela ezimbini: ngokulinganisa ukushisa okusemgangathweni (ngomhla we-ovulation, izinga lokushisa liza kuphakama ngama-0.4-0.6 degrees) okanye kusetyenziswe iimvavanyo ezizodwa zokuvuthwa .
Ukuvuthwa kunye ne-calculator yokumisela isondo somntwana
Enye indlela yokufumanisa ukukhulelwa kwenkwenkwana okanye intombazana ngomhla we-ovulation yile tafile ebonisa isondo somntwana ngenyanga yokukhulelwa kunye nenani lomama.
Kodwa ungazama ukubala isondo somntwana usebenzisa i-calculator ye-intanethi. Ukwenza oku, faka inombolo yosuku lokuqala lwenyanga, ubude bokuphuma kwindoda, kwaye kubandakanye ukubalwa kwesondo esicwangcisiweyo somntwana. Ingakanani umphumo ochanekileyo wale calculator ayikwazi ukugwetywa ngokuthembeka.
Ngoko, waqhelana nekhalenda ye-ovulation kunye neendlela zokwenza isondo somntwana, kodwa ungakulibali ukuba akukho nanye yale ndlela ayinikezeli umphumo we-100%. Kwaye isondo somntwana ongakazalwa unokuthenjwa ngakumbi kwisifundo sesibini esicwangcisiweyo se-ultrasound.
