ʻO ke kaʻina o ka huiʻana o ka wahine alakaʻi i ka hoʻomakaʻana o ka hānauʻana -ʻo kēia paha,ʻike paha nā mea a pau i kēia lā. I ka manawa mua, hiki i kāu mau mākua ke ho'āʻo e wehewehe i kēia, no ka mea, e huli ana i nāʻano'ōlelo a me nāʻano likeʻole. A laila haʻiʻia iāʻoe e pili ana i kēia kumu, e hoʻohana nei i nā'ōlelo lapaʻau. Ma nāʻanoʻelua,ʻo ka moʻolelo, ma keʻano he kūlana, ua uhiʻia a kaumaha paha me nā hua'ōlelo a me nā'ōlelo.
Ka hana o ka uluʻana
Ma hope o ka pauʻana o ka palapala hōʻailona me ka hanaʻana i keʻano o ka wahine, aia ma ka awelika mai 100 a hiki i 300 miliona spermatozoons. ʻO ka meaʻoi loa a me ka pono o ia mau mea ma hope o nā minuke heʻelua wale nō e hele i ka kōpū, kahi i loko o nā hola he 2-3 i nā pauku hope o nā mumlopian tubes me ka mākaukau no ka uluʻana i nā hua manu.
Hiki ke kanuʻana i ka hua manu, ma keʻano he kūlana, i kekahi manawa o ka malama -ʻo ka manawa e ulu ai ka ulu. I kēia manawa, haʻalele ka hua i kaʻeleʻele a hoʻomākaukau i ka huiʻana me ka sperm. ʻO keʻano o ka huiʻana o ka wahine,ʻo ia ka huiʻana o hoʻokahi pūkē me ka hua hoʻokahi, a ma muli o ka hopena o ka hoʻokumuʻiaʻana o kahi embryo. ʻO kaʻoiaʻiʻo, ma ke kumu mua,ʻo ka'ōpiopio ka mea hiʻona hoʻokahi - he zygote, kahi lōʻihi e ulu a hoʻomohala.
ʻO ka hui hui lōʻihi
Inā he nui ka spermatozoa maʻamau, a laila nui ka hāpaiʻana. Malia paha ka huiʻana o nā spermatozoaʻelua o ka hua hoʻokahi, a laila uaʻikeʻia ka mālamalama he māhoe odnoyaytsovye, e like me ka lua o nā lelo o ka wai. Loaʻa i kēlā mau keiki nā mea likeʻole i ka'ōpū o ka'ōpū: ka holo, ka'ōpū, ka placenta, a me nā genetics. He mea pono keʻike e pili ana nā māhoe ma ka papahana hoʻolālā i kekahi i kekahi, aʻo ka makeʻana o kekahi i ke kumu o ka makeʻana o ka lua.
Inā hoʻomohu nā spermatozoaʻelua i nā hua likeʻole, a laila loaʻa nā keiki e nā mea noho wale nō. Hiki i nā pēpē keʻano likeʻole a me keʻano likeʻole o kēlā me kēia, no ka mea heʻano likeʻole ka placenta, ka holo koko, ka membrane a me nā moʻo i ka wā e ulu ana. Inā ma ka hāpaiʻana, e make ke kōpē, i ka lua o ka mea e kōkua ai i ke ola.
ʻO ka hānauʻana he nui ka hopena o ke kuʻiʻiaʻana o kahi wahine. Eia kekahi laʻana, i ka manawa o ka hoʻomaʻamaʻaʻana i ka maʻiʻole, hanaʻia ka hyperstimulation ovarian, kahi e alakaʻi ai i ka nui o nā huaʻelua aʻekolu paha. ʻO keʻano o ke ECO ke kauʻana i kekahi apo i loko o ka'ōpū, no ka mea, he mea liʻiliʻi ka loaʻa o ke kumu. Akā, aia kekahi mau hihia ināʻaʻole hiki ke hoʻololi waleʻia hoʻokahi'ōpiki - no laila, he mau māhoe aʻekolu.
I kēia mau lā, nā hihia o ka hoʻokomoʻiaʻana o nā wāhine, a hiki i ka manawa iʻikeʻia ai heʻano mele, ua hoʻonuiʻia. I mea e ulu ai ka uluʻana a me ka hāpaiʻana i mea maʻamau i kahi ala kūlohelohe, pono i kahi wahine ke heleʻana i ka'ōpiopio a me ka'ōpani lele. Akā pinepine ka hopena, ma muli o ka hana a iʻole ka maʻi i hoʻololiʻia, hoʻokahi wale nōʻoihana'ōmaʻomaʻo, aʻo kekahi o nā mea e pili ana i ka'elepele o kekahiʻaoʻao. Akā e like me ka hōʻikeʻana, hiki i ka huiʻana o ka wahine ke hana ma kēia hihia.
Ovum ma hope o ka hoʻopaʻaʻana
Peheaʻoe eʻaʻaʻole ai eʻike i nā hōʻailona o ka hoʻolālā - ke hanaʻia he mau hola wale nō ma hope o ka pauʻana o ka moekoloheʻana. A hiki mai ka'ōpū i nā lā 6-7, i ka wā e ulu ana ka hua manu i ka'ōpū. No laila,ʻo nā hōʻailona o ka'ōpū eʻikeʻoleʻoe ma mua o hoʻokahi pule.
Hoʻomaopopo nā loea o ka hōʻai'ē i nā kāne ma muli o ka wā o ka'ōhūʻana i ka hikiʻana i ka huiʻana a nui ma hope aku. ʻO ka ovum ma hope o ka uhiʻana e hoʻomau i kāna hana no nā hola he 24, aʻo kahi spermatozoa e hiki ke hana no nā lā he nui.
