Zoyendetsedwa ndi Guardian.co.ukNkhaniyi lotchedwa “Kodi achinyamata ndi chibadwa ofooka umuna?” linalembedwa ndi Hannah Devlin, sayansi makalata, chifukwa theguardian.com Lachitatu 18 February 2015 06.01 UTC

Anyamata kale ndi zochita zambiri nkhawa: mawanga, atsikana ndi laling'ono la "chinthu", monga Adrian Mole mwina ananenera. Kodi vuto la kukhala ndi majini ofooka mwana umuna ankafunikadi zidzawonjezedwa kwa mndandanda?

Asayansi pa yunivesite ya Cambridge amanena ndi choncho pambuyo pogwira kuphunzira zokhudza oposa 24,000 makolo ndi ana awo. Kuwunika maganizo ting'onoting'ono majini kusiyana pakati pa makolo ndi ana, omwe ankaganiza kuti chifukwa cha kukopera zolakwika dzira kapena umuna maselo.

Phunzirolo limasonyeza kuti, pa avareji, makolo amapatsira zisanu nthawi yambiri ya kusintha kwa ana awo ngati amayi. Zimenezi zikusonyeza umuna DNA ndi wochepa okhulupirika kugawanika kwa bambo kumtundu akuyambira, mwina chifukwa umuna maselo akhala akukonza kwambiri kuposa magulu wamkazi dzira ndi nthawi mimba kumachitikita.

Pamene chidwi amanena - ndi amene tiri chidwi kwambiri - n'chakuti zolakwa kugunda mu umuna maselo a anyamata ndi za 30% kuposa kuti anyamata.

Akatswiriwo ndinene izi akanakhoza kufotokoza chifukwa ana achinyamata makolo ndi apamwamba chiopsezo cha matenda monga Matenda achilengulengu, oyambitsa misala ndi spina msana.

Pepala la wolemba, Peter Forster, anati: "Ana 15 wazaka anyamata ndi za 30% masinthidwe kwambiri kuposa ana a anyamata. Ndi J woboola pakati yogawa. "

Zikuoneka anawamasulira ku chiopsezo vuto lobadwa pafupifupi 2% pakuti anyamata, poyerekeza ndi avareji chiopsezo 1.5%, iye anati.

Forster anati: "Izo zikhoza kukhala kuti lonse umuna kupanga dongosolo zolakwa amakonda kumayambiriro ... kuti basi si wokometsedwa panobe."

Iye ananena kuti chiphunzitso anali chinachititsa lingaliro, ndi wina Mtolankhani, kuti ngati anyamata masturbated kwambiri, iwo angathe kugwira ntchito njira yawo kudzera "suboptimal" nthawi zambiri mofulumira.

Pamaso achinyamata kutsatira mfundo imeneyi (musati kale kuthera ndithu yochuluka ntchitoyi?), ndi ofunika kuyang'ana pepala palokha, mu Royal Society Journal Zokambirana B.

The wosamvetseka chinthu ndi anasiya a J woboola pakati pamapindikira. Pano pali Zithunzi, amene amaoneka ngati mzere wolunjika kwa ine.

N'zoona kuti deta imene anyamata angasonyeze anatero apamwamba chiwerengero cha masinthidwe kuposa kwa 20- kwa zaka 30. zaka zosiyanasiyana, koma ikuonekabe kuti alipo ndi 95% chidaliro imeneyi kwa liniya azimuth. Sindikuona aliyense m'pomveka kunena kuti "nyongolosi maselo a mwana anyamata zosiyana ndi okalamba ulamuliro", monga olemba kuchita.

Ngati anali kupita pansi kuti wopita, Mungadzifunsenso chifukwa umuna akupita pang'ono dodgy pa 30, koma kenako akuchira kachiwiri ndi kufika pakati m'badwo, chifukwa zikuoneka kuti ndi kukwera mu 30-35 gulu. A chosavuta kufotokoza ndi kuti deta pang'ono phokoso.

Allan Pacey, pulofesa wa andrology pa University of Sheffield, akugwirizana: "Izi sizikupanga nzeru kwa ine. Ine sindikuwona ndi J woboola pakati ubwenzi ndi, mwa mawu a zamoyo, Ine sindingakhoze kuganiza chilichonse chomwe kufotokoza izo. "

Forster anatchulapo zingapo anthu maphunziro, amene Zokuthandizani kuti atsikana makolo angakhale zambiri ndi ana osiyanasiyana matenda. Koma n'zovuta kunena ngati izi zili zogwirizana mwachindunji zachibadwa zimene zimayambitsa kapena ndi chilengedwe zinthu. Za ine, izi atsopano studydoes kuchita zambiri nkhani. Monga Pacey akunenera: "Ine sindikuwona aliyense nkhawa kwambiri Mtsikana abambo."

Ndipo anthu anyamata amene si abambo, pali mwina zifukwa zina kudikira mpaka 20s kuti ulendo utate.
