Tiyeni tiyambe ndi mawu oyambirira. Spermatozoa amagawidwa m'magulu awiri:
- ndi zigawo za X chromosomes;
- ndi ma Y chromosomes.
Atsikanawa amachokera kuphatikizapo X-chromosomes (XX), ndi anyamata ochokera ku X ndi Y (XY). Monga mukuonera, ngati mukufuna kudziwa momwe mungakhalire ndi mwana molondola, muyenera kuonetsetsa kuti mukupita ku chiberekero cha Y-spermatozoon.
Tidzakambirana momwe tingachitire izi.
Pose
X-spermatozoa amakhala ndi moyo masiku asanu ndi asanu mu chikhalidwe cha acidic cha mkazi, amayamba kuyenda mofulumira ndipo amakhala ndi kukula kwakukulu - mwayi wopulumuka ndi wokwera kwambiri. Y-spermatozoa amakhala maola 24, ndi ochepa komanso mofulumira.
Kotero, ndi phindu lotani kuti akhate mnyamata, ndi kumvetsa za pamwambapa? Mphunoyi imayenera kulimbikitsa kuthamanga kwachiberekero pafupi ndi chiberekero, kotero kuti spermatozoa ndi Y se "atapambana" mpikisano wa X-spermatozoa.
Pochita izi, zonsezi ndizoyenera, kumene mkaziyo ali wochokera pansi ndi kumene munthu angalowemo mbolo yake mozama momwe zingathere.
Odziwika kwambiri ndi oyesedwa:
- "Mishonare" akubwera;
- Makhalidwe a "machitidwe apamwamba" - mkazi amaima pazinayi zonse, mwamuna amalowa mukazi mmbuyo;
- pena "supuni" - abwenzi onse awiri akugona kumbali yawo, bambo amalowa kumbuyo.
Kuchokera pa zochitika zamoyo, amayi amafunika kumvetsera kuti mwina palibenso chiberekero :
Ngati pali bend, dziwani kuti ndi mbali yanji yomwe ili kumbali iyi; Ngati kachilombo ka HIV kamapezeka pamtundu waukulu - mumayang'ana kumalo a bondo.
Ndi liti?
Koma vutoli sikutsimikiziranso kwenikweni. Poganizira funso la momwe mungakhalire bwino mwana wamwamuna, samalani tsiku la kugonana.
Kuti mimba ikhale ndi anyamata apange maola makumi awiri ndi awiri asanayambe mliri wa ovulation ndi maola khumi ndi awiri pambuyo pake.
Apanso, chifukwa chake chiri mufupi moyo wa Y-spermatozoa, komanso kusungidwa kwa X-spermatozoon nthawi yayitali mu chikazi. Kuonjezerapo, zimalimbikitsa osachepera masiku awiri osamalana , kuti abini panthaŵi yomwe ali ndi pakati sanachite mwangozi X-chromosome kuchokera ku kugonana koyambirira.
