Bangaki isidoda bukhoma, futhi bangaki zikhishwa ngesikhathi ejaculation

Isidoda amaseli - iduna ubulili amaseli, awo adedelwa ngesikhathi ejaculation (ejaculation). Basuke akhiqizwa testes (amasende). Ngenxa yalokho yale nqubo, indoda njalo aqoqana kusuka 50 000 kuya ku-100 000 isidoda. Ngakho, nsuku zonke e emasendeni ikhiqizwa kwezigidi ezingu-72 laya ezigidini ezingu-164-germ cells. Kulokhu, abaningi bakhathazekile ngomphumela kangakanani isidoda izimpilo, futhi kanjani they ngokujwayelekile kumele abelwe.

Eqinisweni, isilinganiso sobude bokuphila lwegciwane amaseli besilisa incike izimo lapho bezithola. Ngakho, ngokwesibonelo, endaweni evulekile, bephila isikhathi eside impela - esingaphansi kwamahora ambalwa. Abaningi bayazibuza mayelana isidoda eziningi kanjani bukhoma e sangasese. Namuhla kakhulu eyaziwa lokuthi la mangqamuzana abakwazi ukusinda isikhathi eside e imvelo esidi, okuyinto eyenzeka ngo-sangasese. isikhathi sawo sokuba ukuphila lapha ingeqi ukuthi lapho kungabonwa ngaphandle. Kufanele kube baqonda ngokuyikho ukuthi nguye amaseli ezithathekayo ezifana fast ngokwanele ukushiya isabelo sokuqala insikazi ipheshana zangasese. Izinga kwesidoda ezinyakazayo cishe 3 mm ngehora. Okulandelayo, zingena wesibeletho. Sekube isimo ane-alikhali. Mayelana isidoda eziningi kanjani bukhoma endaweni enjalo, ososayensi abaningi bathi. Naphezu kokungaboni ngaso linye, singasho ngokuqiniseka ukuthi wesibeletho germ cells besilisa iphila 2 kuya ku-7 izinsuku (ngokuvamile 3-5 izinsuku). Sonke lesi sikhathi, iqanda kungenziwa avundiswa ngomunye wabo. Kulokhu, isidoda ezithakazelisa ngoba izici zazo avumele ukubamba iqhaza ukuzalwa umzimba omusha kuphela "izinga" wabo. Iqiniso liwukuthi kancane ucansi amaseli owesilisa noma liyafa ngaphezulu sangasese, noma abanawo isikhathi nozakwabo beshesha kakhudlwana. Yiqiniso, zonke "deffektnye" isidoda futhi iqedwe ngesikhathi mncintiswano.

Ngokuvamile, umbuzo kwezinsuku eziningi kanjani abahlala isidoda, banikwa yilabo abafuna ukuba babe nomntwana. Kuyaphawuleka ukuthi nakuba khona ozimele ezithile (2-7 izinsuku) ngayinye germ cells wesilisa leli gama lihlukile. Ingxenye enkulu yale ndawo ekutheni yimalini "izinga" e isidoda sakhe. Iqiniso lokuthi igciwane amaseli ngokwabo akhawunti kuphela ingxenye encane yawo (3%). Yonke enye into - lena imfihlo izakhi, lapho esaphila isidoda luyanda kakhulu. Ngaphezu kwalokho, kubalulekile ngokwanele ukuba inani eliphelele sperm germ cells kuwo. Namuhla kuyinto evamile, uma kungekhona esingaphansi 2-3 ml isidoda ezikhishwe phakathi ejaculation. Isidoda okuqukethwe therein Kufanele ibe ngaphansi kuka-20 ayisigidi 1 ml. Kuleso simo, uma engaphansi, cishe kungakhathaliseki ukuthi ziningi kangakanani uhlala isidoda, kusukela amathuba kokukhulelwa sincane kakhulu. Ukubaluleka kwalokhu sibalo kuqinisekiswa yokuthi uma uma imibhangqwana ungatholi ukuba izingane sho ngalesosikhathi fike of cwaningo lokuqala, esiqhutshwa, kuyinto ukuhlaziywa isidoda. Mhlawumbe isici esibaluleke kunazo ke - ukunquma eziningi kanjani isidoda akhawunti ngayinye ml kwesidoda.

Naphezu kweqiniso lokuthi iminyaka yokuphila isidoda, ososayensi namanje phikisana, singasho ngokuqiniseka ukuthi kwezimo ezivamile, le nkathi ngempela ngokwanele ukuba wobulili amaseli besilisa zalisa iqanda.
