• Kubalulekile ukugcina isayensi phambili kwezinganekwane

Ngomusho owodwa, ibhayoloji yezocansi ingabonakala ilula kakhulu kunokusebenzisa isingathekiso esithi "izinyoni nezinyosi". Isidoda siyakhishwa kuphume umthondo, singene esithweni sangasese, bese sibhukuda umgudu wokuzala uze ufike eqandeni ukuwufaka umanyolo.

Kodwa akulula kangako.

Cishe eminyakeni engama-300 eyedlule, kwathathwa njengokubamba iqhaza okukhulu kwezesayensi lapho ososayensi beza nombono wokuthi umuntu owakhiwe ngokuphelele, omncane uhlala ekhanda lesidoda ngasinye - onenkinga ngokuphelele futhi ongelona iqiniso.

Ngenhlanhla, njengoba umzimba womuntu uguquke ngaphezu kwezinkulungwane zeminyaka ukukhulisa amandla okuzala, kanjalo nokuqonda kwethu kwesayensi mayelana nesidoda. Kepha abaningi bethu basakholelwa ezinye izinganekwane ezinhle zesidoda ezingezona ezesayensi. Nazi eziyishumi nambili ezivame kakhulu.

1. Isidoda siyabhukuda njengabasubathi bama-Olympic

Inganekwane ejwayelekile ukuthi izigidi - noma yikuphi kusuka ezigidini ezingama-20 kuye kwezingama-300, ukucacisa - zesidoda sobuqhawe sibhukuda ngokuncintisana ukuze sibe yinhlambi encane yenhlanhla engena eqandeni.

Cha.

Okokuqala, isidoda asibhukudi siqonde - ikakhulukazi. Imvamisa ikhono lokunyakaza kwesidoda, elaziwa njenge-motility, lihlukaniswa ngeqembu elilodwa:

• motility eqhubekayo: ukuhamba ngentshiseko kulayini oqondile noma imibuthano emikhulu
• ukuhamba okungaqhubeki: noma iyiphi enye iphethini ngaphandle kokuya phambili
• immotile: ayinyakazi

Endabeni ka-Aeon, uRobert D. Martin uchaze lo mzila ngokuthi “ufana nenkambo yezithiyo ezithiyayo enselele” futhi ungaphansi komjaho ojwayelekile. Futhi noma kunjalo, isidoda sidinga okungaphezulu kokunyusa okuncane kusuka ohlelweni lokukhiqiza lwabesifazane ukuze siqiniseke ukuthi sifinyelela entanjeni.

Eqinisweni, iningi lomsebenzi we-motility wenziwa yimisipha yesibeletho. Ihlanganisa isidoda siye kumashubhu e-fallopian, iye eqandeni.

2. Isidoda esijiyile yisidoda esivundile

Isidoda esijiyile akusho ukuthi isidoda esijiyile. Imvamisa kusho ukuthi kunokuhlushwa okuphezulu kwesidoda noma inombolo ephezulu yesidoda esimise ngokungajwayelekile. Basadinga usizo oluvela ohlelweni lokuzala lwabesifazane ukuze bahlale bephephile.

Lapho isidoda singena esithweni sangasese, sihlangana nesicubu somlomo wesibeletho. I-mucus yomlomo wesibeletho yenza izinto ezimbili: ivikela futhi yenqabe. Kuvikela isidoda ebuswini besitho sangasese sowesifazane futhi kwala nesidoda okuma kwaso nokuhamba kwaso kungenza ukuthi zingafinyeleli eqandeni.

Indlela uhlelo lokuzala lokuzala olusiza ngayo isidoda:

1. Umlomo wesibeletho - isicubu esiphakathi kowesifazane nesibeletho - izindonga ziyanwetshwa.
2. Ama-crypts, noma izindlala zomlomo wesibeletho, zikhula ngenani futhi zikhule ngosayizi ukugcina isidoda esithe xaxa.
3. Isithiyo somlomo wesibeletho somlomo wesibeletho siyancipha ngakho-ke kulula ukuthi isidoda sidlule.

3. Isidoda siphila isikhashana nje ngemuva kokukhishwa

Hhayi njalo! Isikhathi sokuphila sincike ekutheni isidoda sihlala kuphi ngemuva kokukhishwa.

Isidoda esikwenza ungene esithweni sangasese sowesifazane ngemuva kokukhishwa kwesisu singaphila izinsuku ezinhlanu. Lokhu kungenxa yemiphumela yokuvikela amafinyila womlomo wesibeletho nama-crypts womlomo wesibeletho.

Kepha uma isidoda sinethuba lokoma, ngokuyisisekelo siyafa. Isidoda esidliwayo esiwela ezintweni ezibandayo, ezomile singafa ngemuva kwemizuzu embalwa - yize kuyaqabukela kungahlala imizuzu engama-30 yonke. Bangafa ngokushesha okukhulu kubhavu oshisayo noma kubhavu oshisayo ngenxa yokushisa noma amakhemikhali asemanzini.

4. Isidoda sidinga ukuqonde ngqo eqandeni

Luhambo olude oluhle oluya eqandeni. Ngesikhathi sokuya ocansini, lapho isidoda sishiya ipipi, asiqonde ngqo esibelethweni.

Kulesi sifundo, esinye isidoda sinamathisela kumaseli e-oviduct epithelial kumashubhu we-fallopian noma sigcinwe emakamelweni amancane abizwa ngama-crypts kuze kube yisikhathi sokukhulelwa kuqala: i-ovulation.

Indlela eya ekukhulelweni: lapho isidoda sidinga ukudlula ngaphambi kokufinyelela eqandeni

• isitho sangasese sowesifazane: ingxenye yokuqala nengaphandle, ngokwesilinganiso amasentimitha amathathu kuya kwayisithupha
• umlomo wesibeletho: umsele omncane, oyindilinga ohlanganisa isitho sangasese sowesifazane nesibeletho
• isibeletho (noma isibeletho): lapho umbungu ukhula khona ngesikhathi sokukhulelwa
• amashubhu we-fallopian: amashubhu amabili axhumanisa isibeletho nama-ovari, avumela isidoda ukuba siye emaqenjini amaqanda namaqanda avundisiwe ukuze angene esibelethweni
• amaqanda: izitho ezimbili ezikhiqiza amaseli amaqanda angavundiswa abe yizimbungu

5. Isidoda sihlala sivundile futhi sinempilo impilo yonke yomuntu wesilisa

Enye yezinganekwane ezindala kakhulu eziphikelelayo ukuthi ngenkathi kunenani elilinganiselwe lamaqanda (okuyiqiniso), isidoda siyatholakala ngesikhathi sokuphila konke.

Hhayi ngokushesha okungaka.

Ukukhiqizwa kwesidoda, noma i-spermatogenesis, kwenzeka ngokungapheli, kepha ikhwalithi nokuhamba kwesidoda kuyehla ngokukhula.

Amadoda amadala nawo maningi amathuba okuthi adlulisele ukuguqulwa kwezakhi zofuzo ezinganeni zawo, cishe, ngokusho kocwaningo lwase-Iceland.

Ucwaningo lwango-2017 lwabantu abayizigidi eziyi-1.4 eSweden lwathola ubudlelwano obungaguquguquki obulinganayo phakathi kweminyaka yobudala bendoda kanye nethuba lokuthi izingane zakhe zizozalwa zine-mutation yezakhi zofuzo engenaye umzali.

6. Izifinyezo azilungile kubalwa besidoda sakho

Ngokusobala, ama-undies aqinile anciphisa ukubalwa kwesidoda, kuyilapho abashayisibhakela abangaxegiyo begcina konke kushisa okulungile lokukhiqiza isidoda.

Kepha izingubo zangaphansi (cishe) azinawo umthelela esidunjini sakho.

Ucwaningo lwango-2016 luthole umehluko omncane ekubalweni kwesidoda ngokususelwa ekukhetheni izingubo zangaphansi. Kepha ucwaningo lwango-2018 lwenze amagagasi esayensi lapho kuthola ukuthi abesilisa abagqoka abashayi besibhakela banesidoda esingaphezulu ngamaphesenti ayi-17 kunamadoda ngamafuphi.

Kodwa ababhali bocwaningo bango-2018 baxwayisa ngokuthi imiphumela yabo ibingazibali ezinye izinto ezithinta ukukhiqizwa kwesidoda, njengohlobo lwamabhulukwe noma ukuthi zenziwa ngani izindwangu.

Futhi uthole lokhu: Umzimba unganxephezela ukushisa okwengeziwe kwamasende ngokukhipha i-hormone eshukumisa isidoda eyengeziwe ekhiqiza isidoda.

Ngakho-ke, abashayisibhakela bodwa kancane ukusebenziseka kalula kwesidoda. Gqoka okwenza ukhululeke.

8. Sonke isidoda sinempilo futhi siyasebenza

Akunjalo.

Iningi lesidoda alikaze lifike eqandeni ngezizathu eziningi. Ukuze ubhekwe njengokuvundile, noma amaphesenti ayi-100 wesidoda kudingeka ahambise - inqobo nje uma amaphesenti angama-40 ehamba, uvundile!

Futhi kulawo maphesenti angama-40, akubona bonke abafika eqandeni.

Isimo sinokusho okuningi empumelelweni. Ukuba namakhanda amaningi, imisila emise okwexakile, noma izingxenye ezingekho kungenza isidoda simane singakulungeli uhambo ngomgudu wokuzala wabesifazane.

Futhi nesidoda esinempilo akusenzi ngaso sonke isikhathi ngomncintiswano. Isidoda singadlula ngqo kwi-oviduct futhi sigcine sikuketshezi oluphakathi kowesifazane oluzungeze izitho zangaphakathi. Kunjalo, isidoda singantanta ngokoqobo emzimbeni, singaze sivundiswe.

9. I-pre-cum ayikwazi ukukukhulelisa

Amanga! Kakhulu. Ukukhuluma ngokwebhayoloji, i-pre-cum akufanele ibe nesidoda - kepha isidoda esisele ku-urethra, ishubhu lapho kukhishwa khona umchamo nesidoda, lingaxubeka phakathi.

Impela, azikho eziningi njengasesidunjini esisha, kepha i-a ikhombise ukuthi cishe amaphesenti angama-37 amasampula wangaphambi kwe-cum aqoqwe ezifundweni ezingama-27 zocwaningo aqukethe inani elikhulu lesidoda esinempilo, semotile.

Futhi kwabesilisa abangama-42 bathola ukuthi okungenani amaphesenti ayi-17 amasampula wangaphambi kwe-cum ayegcwele isidoda esisebenzayo, esisebenzayo.

Ngakho-ke noma ngabe usebenzisa indlela yokukhipha, kunethuba elincane lokuthi esinye isidoda singakhululeka futhi sidale ukukhulelwa.

10. Isidoda esithe xaxa singcono uma uzama ukukhulelwa

Ngokuphambene nalokho.

Ukuba nevolumu yesidoda ephezulu, ebala isidoda nge-ejaculation eyodwa, kuhle kodwa kunephuzu lapho izimbuyiselo ziqala ukuncipha. Ukuphakama kokuhlushwa kwesidoda, maningi amathuba okuthi isidoda esiningi singavundisa iqanda.

Imvamisa, kuvunyelwa kuphela isidoda esisodwa esinengqamuzana elilodwa ukukhulisa iqanda elilodwa leqanda, okuholela ekukhuleni kombungu. Ngemuva kokuthi isidoda sokuqala sidabule ungqimba lwamaprotheni azungeze iqanda, lolu ungqimba luvimbela isidoda esithe xaxa ukungena.

Kepha uma isidoda esiningi sifinyelela eqandeni, amabili - noma ngaphezulu, ezimweni ezingavamile - isidoda singadabula lolu ungqimba bese sigcina sivundisa iqanda. Lokhu kubizwa ngokuthi yi-polyspermy.

Ngokuletha izinto ezengeziwe zofuzo eqandeni, lokhu kukhulisa ubungozi bokushintshwa kwe-DNA, izimo zobuchopho ezifana ne-Down syndrome, noma ukukhubazeka okungaba yingozi enhliziyweni, emgogodleni nasokhakhayini.

Gcina lokhu engqondweni uma wena nomlingani wakho ninquma ukusebenzisa in vitro fertilization (IVF) ukukhulelwa. Ngoba i-IVF idlula imisebenzi eminingi yokuzala ebekela umkhawulo wesidoda esifika eqandeni, isidoda sakho asidingi ukuba nezigidi zesidoda ukuze sivunde.

11. Isidoda yindawo yamandla wamaprotheni

Le yinganekwane ethandwayo okungenzeka ukuthi ihlekiswa ngayo njalo. Kodwa kuzofanele ufake ama-ejaculates angaphezu kwama-100 ukuze ubone noma iyiphi inzuzo yokudla okunempilo kuwo.

Yize kuyiqiniso ukuthi isidoda sakhiwa izithako ezifana novithamini C, zinc, amaprotheni compounds, cholesterol ne-sodium, ukumangalela ukuthi isidoda sinikela kunani lakho lokudla nsuku zonke ukukhangisa okungelona iqiniso.

Futhi, abanye abantu empeleni banokungezwani komzimba nesidoda, ngakho-ke ukungenisa akukhuthazwa njalo.

12. Uphayinaphu wenza isidoda sakho sinambitheke ngendlela emangalisayo

Akuwona nje uphayinaphu abantu abathi kufanele ukuthi ulungele ukunambitheka kwesidoda, kodwa ayikho neyodwa yezinganekwane esekwe kwisayensi.

Into yokuqala ongayifunda lapha ukuthi iphunga lesidoda nokunambitheka, njengalokhu okuningi koketshezi lwakho lomzimba, kuthonywa ufuzo jikelele, ukudla kanye nendlela yokuphila. Njengokuphefumula kwawo wonke umuntu kunuka okwehlukile, ikhumu lawo wonke umuntu linephunga lalo elihlukile.

Into yesibili ukuthi, ngenkathi kungekho ukudla noma iziphuzo ezingashintsha iphunga lesidoda ngokusobala, ukulandela ukudla okunomsoco onjengevithamini C no-B-12 kungaba nemiphumela emihle ekubalweni kwesidoda, morphology, nase motility.

Kubalulekile ukugcina isayensi phambili kwezinganekwane

Ezinye zalezi zinganekwane zibuyela emuva emibonweni (yamanga) yesimo sobudoda esinqunyiwe, kepha eziningi zazo zisitha iqiniso lokuthi ukukhulelwa, njengokuya ocansini, kungukubambisana okusebenzayo.

Ukukholelwa kulezi zinganekwane nakho kungaholela emibonweni eminingi engalungile noma enobuthi. Ngokwesibonelo:

• ukuvezwa kwabesifazane njengabangenzi lutho besidoda kunokuba babe ngabalingani abalinganayo ocansini
• imizwa yokungafaneleki yokuba nesibalo esiphansi sesidoda
• ukusola umlingani oyedwa noma omunye ngokuthi "angadonsi isisindo sabo" lapho ezama ukuthola ingane lapho ezinye izinto eziningi kufanele zibhekwe

Ubulili nokukhulelwa akuwona umncintiswano noma amandla: Kuyimisebenzi yeqembu lapho bonke ubulili bunezinga elilinganayo, noma ngabe ukhiqiza isidoda noma amaqanda. Kuyizindlela ezimbili, kodwa akekho okufanele azizwe sengathi kumele azihambele yedwa.
