Powered e Guardian.co.ukTēnei tuhinga ui “Kei te taiohi i parāoa ira ngoikore?” e Hana, Devlin i tuhituhia, kaituhi pūtaiao, hoki theguardian.com i te Wenerei 18 o Pēpuere 2015 06.01 UTC

Mau tamaroa Teenage kē nui ki te manukanuka: wahi, kotiro, me te rahi o to ratou "mea", rite Adrian Mole kua hoatu ai i te reira. E Me tino te raruraru o ia ira ngoikore parāoa taiohi ki te te tāpiri ki tēnei rārangi?

Kua fokotu'u Scientists i te University o Kemureti ko te take i muri i whakatutuki i te ako e pā ana neke atu i te tenei 24,000 te mau metua, me a ratou tamariki. Arotahi te tātari i te iti ira rerekētanga i waenganui i ngā mātua me te uri, e riro ki te kia i meinga e te tāruatanga hapa i roto i te hua parāoa ranei pūtau.

E whakaatu ana te ako e, i te toharite, matua haere i runga i te iti rawa e ono wa kia rite ki te maha o enei irakētanga ki a ratou tamariki kia rite ki whaea. Tenei kōrero parāoa DNA ko te tukuruatanga iti pono o te raupapa ira te papa o te, no te mea pea i oti pūtau parāoa nui atu i te pūtau hua wahine wehenga i te wa puta haputanga.

Ko te kerēme atu a Tūrongo, - me te tetahi i ka whakarongo te nuinga - ko e te auau hapa i roto i nga pūtau parāoa o mau tamaroa hongofulu ko e pā ana ki 30% runga ake i taua hoki nga taitamariki.

Ko te kairangahau mea tenei i taea e whakamārama he aha i nga tama a hongofulu matua he nui ake te mōrearea hoki disorders pērā i tūāwhiotanga, tuakoi me te ritua tuaiwi.

Kaituhi o te pepa, Peter Forster, mea: "E tamariki o te mau tamaroa-tau 15-tau e pā ana ki 30% atu irakētanga i to nga tama a te tangata taitamariki. Ko te he tohatoha J-āhua. "

Iritihia pea tēnei ki te mōrea o te hē whanau o e pā ana ki 2% no te mau tamaroa hongofulu, whakaritea ki te mōrea toharite o 1.5%, ka mea ia.

Na ka mea a Forster: "I taea e te reira e te pūnaha production parāoa katoa, ko te ake hapa e pängia ana i te tīmatanga ... tika e te reira te mea e kore e papaitia ano."

Na ka mea ia i ara ue'i te ariā o te whakaaro, i tetahi atu kairīpoata, e ki te masturbated atu mau tamaroa hongofulu, e taea ki te mahi i to ratou ara ai ratou i roto i tenei wā "suboptimal" atu tere.

I mua i tokanga taiohi i tenei whakaaro (e kore ratou e ia horo'ai kē he rota rawa o te wa ki tenei mahi?), te reira utu titiro i te pepa iho, i roto i te Royal Society Journal Whakahaerenga B.

Ko te mea rerekē, ko te ngaro oti o te ānau J-āhua. Tenei te te kauwhata, e titiro rite te raina tika ki ahau.

Ko reira parau mau e kia whakaatu i te wāhi raraunga mō ngā tama hongofulu he maha paku teitei o ngā irakētanga i to taua mo te 20- ki te awhe tau-tau 30, engari te āhua tonu te reira ki te inaki ki te 95% te māiatanga wā mo te ia rārangi. E kore e taea e kite ahau i tetahi take ki te faaoti e, "i te pūtau te tupuranga o te mau tamaroa taiohi e he okotahi ki te ture toulekeleká", rite nga kaituhi e rave.

Ki te i haere koutou ki te haere ki raro i taua ara, ai fifili hoki koutou he aha haere parāoa he bit dodgy i 30, engari ka ora ano ki te huarahi o te tau waenga, no te mea i reira te mea ki te kia te matau i roto i te 30-35 kāwai. He whakamārama ohie ko e te raraunga, ko te wahi tika maniania.

Allan Pacey, ahorangi o te andrology i te University o Sheffield, whakaae: "E kore e tenei hanga tikanga ki ahau. E kore ahau e kite i te hononga J-āhua, me, i roto i te ngā i te koiora, E kore e taea e ahau te whakaaro o te tetahi e whakamārama i te reira. "

Tohu Forster ki te maha ako taupori, e tohu kia atu pea ki te whai tamariki ki ngā disorders hongofulu matua. Ko te mea uaua ki te mea ranei kei te hono taua hua ki te tika take ira āhuatanga pāpori me te taiao ranei. Hoki ahau, e kore e mahi i tenei studydoes hou nui ki te whakatau i te take. I Pacey e te reira: "E kore ahau e kite i tetahi āwangawanga nui mō Dads hongofulu tupú."

A mo te hunga mau tamaroa hongofulu kahore e nei Dads, i reira e te tahi atu pea take ki te tatari tae noa ki te eke ratou 20 i runga i metua.
