Teenage tub twb muaj txaus txhawj txog: me ntsis, cov ntxhais thiab cov me me ntawm cov "khoom", raws li Adrian Mole yuav tau muab nws. Puas muaj qhov teeb meem uas muaj muaj zog txhob kaw whooping phev yeej yuav muab ntxiv rau daim ntawv no?

Zaum ntawm lub tsev kawm ntawv Cambridge tau pom tias qhov no yog rooj plaub tom qab kev tshawb involving kws ntau tshaj 24,000 cov niam txiv thiab cov me nyuam. Qhov tsom rau ib caj txawv ntawm cov niam txiv thiab zag, uas yog assumed yog tshwm sim los ntawm kev uas tsis luam hauv lub qe los yog cov phev hlwb.

Txoj kev tshawb no qhia tau hais tias, nyob rau nruab nrab, txiv kis tsawg kawg yog rau (6) lub sij hawm ua ntau ntawm cov noob mus rau lawv cov me nyuam uas leej niam. Qhov no qhia phev DNA yog cov tsawg ib tug replication ntawm leej txiv lub caj ib theem zuj zus, tej zaum vim cov phev hlwb muaj undergone ntau zaus dua cov maum nteg qe cell raws lub sij hawm conception tshwm sim.

Cov ntaubntawv ntau striking – ib tug uas tau txais cov xim – yog tias tus nqi yuam kev hauv lub hlwb phev ntawm tub teenage yog hais txog 30% dua li ntawd rau cov txiv neej.

Cov soj ntsuam ntawm hais no yuav piav txog vim li cas cov me txiv teenage muaj ib qhov uas yooj yim dua lawm xws li cov tsi txawj has lug, schizophrenia thiab spina bifida.

Daim ntawv sau, Peter Forster, Txawm hais tias: "Cov me tub 15 xyoo muaj txog 30% xav paub ntau change dua cov me nyuam hluas. Yog tis zoo li tus J."

Qhov no tej zaum txhais ua uas yug los tsis xws luag uas hais txog 2% rau cov tub hluas teenage, piv nrog rau tus mob nruab nrab ntawm 1.5%, Nws hais.

Hais Forster: "Nws yuav yog tias phev tseem ntau lawm lawv yeej ntau yuam kev nws lub caij thaum pib... tias nws cia li tsis optimised tsis tau."

Nws hais tias cov kev tshawb xav muaj txawm prompted lub tswv yim, yog lwm journalist, uas yog tub teenage masturbated ntxiv, lawv tej zaum yuav tau ua lawv txoj kev mus txog lub sijhawm "suboptimal" no loj dua.

Ua ntej hluas mloog qhov suggestion (tsis txhob lawv twb devote kuj muaj ntau lub sij hawm rau cov kev ua no?), sim no muaj nqis saib tus ntawv nws tus kheej, nyob hauv cov haiv neeg muaj koob muaj npe Journal zaug B.

Qhov khib tshaj plaws yog hla kiag nkhaus uas muaj zoo li tus J qhov. Ntawm no yog lub teeb, uas zoo li ib txoj kab ncaj nraim rau kuv.

Yog muaj tseeb tias cov ntaub ntawv taw tes rau tub teenage yuav qhia dua ib nyuag ntau tus noob li ntawd rau cov 20- tau ntau hnub nyoog 30 xyoo, tiam sis nws tseem tshwm los tshaj rau cov 95% qoob loo yuav luv rau qhov sib tawm. Kuv tsis tau pom li cas los xij mus xaus hais tias "lub hlwb ces cov tub hluas whooping muaj kev zam rau ntawm txoj cai ageing", raws li tus sau phau ntawv ua.

Yog hais tias koj twb yuav nqes ntawd lawv, koj kuj yuav tau xav vim phev mus heev lub dodgy ntawm 30, tab sis ntawd zaug ntxiv nrog rau qhov kev hauv nruab nrab, vim hais tias muaj zoo muab ib tug ntsia hlau loj nyob rau hauv lub 30-35 qeb. Ib sob piav yog tias cov ntaub ntawv yuav yog lub ua pa nrov.

Allan Pacey, xibfwb kev andrology hauv lub tsev kawm ntawv ntawm Sheffield, Nws pom zoo: "No tsis ntxim rau kuv. Kuv tsis pom ib tug zoo li tus J kev sib raug zoo thiab, saib raws ib, Kuv tsis tau xav txog tej yam uas yuav qhia tau nws."

Forster ntxiv rau pejxeem kev tshawb fawb ntau, uas hint tias txiv teenage tej zaum yuav muaj cov me nyuam muaj ntau yam mob. Tiam sis koj yuav tsis hais seb cov zoo li no yuav tau yog txuas rau tib neeg ua rau caj los yog lwm yam kev thiab tej. Rau kuv, qhov tseeb studydoes tsis puas yuav daws tau qhov teebmeem. Raws li Pacey txo nws hwj nws: "Kuv tsis pom muaj zoo kawg thiab txhawj txog rau cov pib ua leej txiv teenage."

Thiab rau cov tub hluas teenage yog leej twg tsis txi, muaj tej zaum lwm yam tos kom txog thaum lawv 20s mus embark rau tsa.
