IMIBUZO: Ukushaya indlwabu ku-pornstar yenoveli kwandise ivolumu ye-ejaculate nesidoda se-motile. Futhi, isikhathi esathathwa ukukhipha i-ejaculate sehle kakhulu. Umphumela weCoolidge ubonakala njengomsebenzi omkhulu wesifunda womvuzo lapho uvezwa kumlingani wezocansi onoveli. Lapha, ubuciko bezocansi buhumusha futhi bube yisidoda esingcono nokushesha kwe-ejaculation, okwenza noma ikuphi "ukuhlanganiswa kwama-extra-pair" kube lula kakhulu, futhi kubize kakhulu.

abstract
Abesilisa ezinhlotsheni eziningi babela ngokwehlukana isidoda nokugeleza kwesimilo ngokuya ngokuhlukahluka okuthile kwezenhlalo, kufaka phakathi ukuncintisana kwesidoda kanye nesimo sokuzala sowesifazane. Kwezinye izinhlobo, abesilisa banciphisa ukutshala kwabo ngobuningi besidoda noma ikhwalithi ekuhlanganisweni okuphindaphindwe kowesifazane oyedwa futhi bakhulisa ukutshalwa kwezimali lapho kuzanywa nentokazi. Sihlole imiphumela yokuhlala kokuvuselela okuthile kanye nobunqunu kumakhamu we-semen ejacured kubantu. Sihlaziye ama-ejaculates akhiqizwa ngokushaya indlwabu ngokukhuthaza okuvela kumafilimu abonisa ubulili. Lapho abesilisa bevezwa ngokulandelana ngokulandelana kowesifazane amahlandla ayisithupha, asibonanga lutho olushintshayo emikhakheni ejamoate phakathi kokuvezwa kokuqala nokwesithupha kowesifazane oyedwa. Kodwa-ke, umthamo we-ejaculate kanye nenani eliphelele lesidoda sokulinganisa lenyuka kakhulu lapho abesilisa bevezwa intokazi. Isikhathi sokujwabuzisa futhi sehlile kakhulu ekuvezweni kowesifazane onenoveli. Ngakho-ke, imiphumela yethu iphakamisa ukuthi abesilisa abangamadoda bahlukane ngokushesha futhi batshala imali eningi enama-noveli abesifazane.
ISITATIMENDE SEPHEPHANDABA
Ucwaningo olwenziwe ngabakwaSooster Scientists lubonisa isithembiso sokuthuthukisa inzalo yabesilisa
Ukusebenzisana kwabafundi kunikeza ithemba imibhangqwana izama ukukhulelwa
I-WOOSTER, e-Ohio - Uma imibhangqwana inenkinga yokukhulelwa, imvamisa yilona wesifazane obekezelela ukucutshungulwa okukhulu, kepha ucwaningo olusha olwenziwa ososayensi e-The College of Wooster luveza ukuthi ukuzala kwabesilisa kungahle kungashaywa indiva futhi nokuthi amadoda angakwazi ukukhulisa isibalo sazo zesidoda.
UPaul Joseph, owathola iziqu zeWooster ngo-2014, kanye noLaura Sirot, ongusizi weprofesa webhayoloji eWooster, kanye nabaphenyi eCarlveland Clinic's Center for Reproduction Medicine, bahlanganyele kuphrojekthi, ebheka i-"Coolidge Effect," into ebonakalayo kumamalia Izinhlobo zezilwane lapho ikhwalithi nenani lesidoda sowesilisa bezokwehla ngokuchayeka okuphindaphindiwe kwezithombe zowesifazane ofanayo kepha kamuva kwandiswe ekuvezweni kwezithombe zowesifazane omusha Ucwaningo lukhombisa ukuthi amadoda, njengabesilisa kwezinye izinhlobo zezilwane, atshala kakhulu (okusho ukukhiqiza ivolumu enkulu ye-ejaculate enenombolo enkulu yesidoda semotile) lapho kwethulwa okunhlobonhlobo okuncane. Ukuthola kwabo kushicilelwe kumagazini kaJuni Isayensi Yokuziphendukela Kwemvelo (Psychological Science).
UJoseph noSirot balingisa izimo zokuqhathanisa nabesifazane abajwayelekile nabamanoveli besebenzisa izithombe ezahlukahlukene base behlaziya amasampula e-semen ehlukile. "Imiphumela yethu iveze ukuthi ngesikhathi betholakala ezithombeni zowesifazane osemusha, amadoda aqhamuke ngesivinini esikhulu enamazinga aphezulu obudoda obabunenqwaba yesidoda semotile," kusho uJoseph. "Lokhu kusikisela ukuthi la madoda akwazi ukwahlukanisa phakathi kwalaba besifazane ababili ababonile futhi bakhiqiza imichilo emikhulu ngesidoda esithe xaxa lapho kuboniswa khona owesimame."
Lokhu okutholakele kuhlinzeka ngemininingwane emisha emkhakheni we-biology wokuziphendukela kwemvelo kanye nokusebenza kwengqondo yokuziphendukela kwemvelo komuntu, kodwa ukusetshenziswa kwezokwelapha kwabesilisa kuyathembisa ikakhulukazi, kusho laba besayensi bobabili. "Ukungacabangi kwabesilisa kungahle kutholakale ngaphandle kokuthi izidalwa ezikhiqizwa ukuhlaziya nezinhloso zokuzala ziveliswa ngaphansi kwezimo ezimbili ezihlukene," kusho uJoseph. “Ama-ejaculates akhiqizelwe ukuzala ngokuvamile akhiqizwa nowesifazane ajwayelekile, kanti lawo ahlaziywa esimweni somtholampilo ngokuvamile akhiqizwa ngenkathi kubukwa izithombe ezibonisa owesimame osemusha. Ngakho-ke, ama-ejaculate akhiqizwe emitholampilo yokuzala angaba sezingeni eliphakeme kakhulu kunokujwayelekile, angafihla noma yiziphi izinkinga ezingaba khona zokuzala ezitholakala egumbini lokulala. ”
UJoseph noSirot banethemba lokuthi imiphumela izonikeza ukuqonda kwezindlela zokwenza ngcono ukuxilongwa kanye nokwelashwa kwezinkinga zokuzala, ngaleyo ndlela kukhulisa amathuba okukhulelwa, kuyilapho kusale abesifazane abangenayo izindlela zokuxilonga nokwelashwa.

Kungani Ucansi Olusha Lunika Abesilisa Ngokushesha Okusheshayo
Aug 3, 2015 04: 01 PM NguLizette Borreli
Isidoda esinempilo ngaso sonke isikhathi asinikezwa amadoda. Ubungako, ukunyakaza, kanye nesakhiwo konke kufaka isandla empilweni yezidoda, futhi ngokusho kwakamuva cwaningo eshicilelwe encwadini Isayensi Yokuziphendukela Kwemvelo (Psychological Science), lezi zici zingashintsha nabalingani abasha bobulili.
"Esikutholile kungokokuqala ukukhombisa ukuthi indlela abesilisa abaziphatha ngayo nabashintshana ngayo ngokushintsha kwesisulu sabantu besifazane," kusho abaphenyi baseKolishi laseWooster e-Ohio.
I-physiology yabesilisa nokuziphatha kwaziwa ukuthonya lapho bevezwa abalingani abasha. Ku-2000 cwaningo, ngokwesibonelo, abesilisa bathole ukuvezwa okuphindaphindayo kwisikhuthazo esingavusi ucansi kuphela, kepha futhi nokunganaki kangako nokunciphisayo. Ukuvusa okwazibika ngokwakho, ngakho-ke ukuzungezwa kwe-penile, kwanda lapho amadoda evezwa ezintweni ezintsha zesifazane ngemuva kokujwayela umfutho ofanayo wabesifazane. Lokhu okutholakele kuxhumene nomzimba womuntu ongokwemvelo, osebenza ukukhulisa ubuhlakani ebusweni bomlingani omusha, ngaleyo ndlela kuthuthukise amathuba akhe okuzala inzalo.
Ocwaningweni lwamanje, abacwaningi bafuna ukuthola ukuthi izimfanelo zamadoda eziguqukayo zishintshile yini ukuphendukela ekuvuseleleni abesifazane abajwayelekile noma abasha. Isamba samadoda angama-21 abesilisa abathandana nabobulili obuhlukile phakathi kweminyaka ye-18 ne-23 aqashelwa ukubuka amavidiyo ayisikhombisa abeka ucansi egumbini elingasese njalo ngamahora we-48 kuya kwamahora we-75 ngezinsuku ze-15.
Amavidiyo ayisithupha okuqala abonisa umlingisi ofanayo nomlingisi, kuyilapho ifilimu yesikhombisa yayinomlingisi ohlukile kodwa umlingisi ofanayo. Ividiyo ngayinye ibinesiqeshana semizuzu emithathu kusuka kuvidiyo ende yemizuzu engama-20 futhi ibidlalwa ngokuphindwayo kuze kube yilapho amadoda ekhishwa.
Amadoda ayalwa ukuba aqophe ukuthi aqala ukubuka ifilimu nini, nini akhipha isikhathi, nokuthi wonke ama-ejaculate awo afakwe enkomishini yamaqoqo. Abaphenyi bahlole nesikhathi sevolumu ye-ejaculate kanye Inani lesidoda esivela kumuntu ngamunye obambe iqhaza. Uma enye ye-ejaculate ingayingenisanga endebeni, ayifakwanga njengengxenye yedatha.
Okutholakele kuveze ukuthi isikhathi esithathe ababambiqhaza ukukhipha umjovo besinemizuzu emine kuya kwengama-21. Uma kukhulunywa ngamafilimu okuqala ayisithupha, bekungekho mthelela wokujwayela, okusho ukuthi ukubukwa kaninginingi kowesifazane ofanayo akuzange kwandise noma kunciphise isikhathi se-ejaculation. Kodwa-ke, bakhipha ijusi ngokushesha futhi ngekhwalithi ephezulu lapho bebuka ifilimu yesikhombisa, ebifaka owesifazane omusha.
Abaphenyi basola ukuthi la madoda kungenzeka ukuthi akhiqize isidoda esezingeni eliphakeme ngesikhuthazo esisha sowesifazane ngezizathu ezimbili. Okokuqala, bakholelwa ukuthi ngokuzenzisa, la madoda abesevele efake amaqanda (amaqanda) noma isidoda sawo sigcinwe ngabesifazane abahlangana nabo. Okwesibili, lokhu okutholakele kuxhumene nomqondo wokuncintisana kwesidoda, okubhekisa emncintiswaneni ophakathi kwesidoda samadoda amabili ahlukene wokufaka iqanda lowesifazane oyedwa. Lokhu kwenzeka kakhulu kumakhophi we-extra-pair - lapho abantu beya ocansini nabanye ngaphandle komlingani wabo.
Ubulili obuvamile bukhanyisa okungaphezu kwesifiso somuntu sokuya ocansini nabangaphezu koyedwa. Kubuye kuthinte nokuthi kanjani ukungabi namuntu uyatholakala futhi angasiza ezinhlelweni zokuzala. Ukuphakamisa ukusebenza okufana kakhulu nezimo ezijwayelekile zocansi, ngokwesibonelo, kungathuthukisa ukunemba kokuxilongwa kokungazali kwabesilisa, ngenkathi ukusebenzisa isisusa sabantu besifazane abasha kungathuthukisa umphumela wezindlela ezisizayo zokuzala.
