Seksualna orijentacija, price<\/a> \u017eelje i nagoni za ljude su oduvek misteriozno polje. I bez obzira na to koliko se nauka trudi da ih objasni, uvek se ?ini da ne\u0161to u teoriji ne stoji.<\/p>\n

Zato i izgleda da istra\u017eiva?i gube vreme sa teorijom koja ka\u017ee da imati starijeg brata pove?ava \u0161anse da neko bude homoseksualac.<\/p>\n

U poslednje vreme istra\u017eiva?i kao da su zaglavljeni s idejom pod nazivom \u201cefekat bratskog redosleda ro?enja\u201d. Ova teorija sugeri\u0161e da mu\u0161karci koji imaju starijeg brata imaju ve?e \u0161anse da budu gej. U stvari, istra\u017eivanja pokazuju da se sa svakim starijim bratom \u0161anse za to pove?avaju.<\/p>\n

Ova teorija priznaje samo biolo\u0161ku bra?u i navodi da nije bitno da li bra?a \u017eive zajedno ili odvojeno. Kada su u pitanju dame, teorija nema nikakvu te\u017einu.<\/p>\n

Podaci ukazuju na to da imati stariju bra?u jeste va\u017ean faktor u homoseksualnosti. Prema seks istra\u017eiva?u Majklu Bejliju iz tima Univerziteta Nortvestern, \u0161anse se kre?u na ovaj na?in.<\/p>\n

\u2013 Pod pretpostavkom da je ?ovek koji nema stariju bra?e ima dva odsto \u0161anse da bude homoseksualac, ?ovek sa jednim starijim bratom ima 2,6 odsto \u0161anse, sa dva, tri i ?etiri starije bra?e \u0161anse su mu 3,5 odsto, 4,6 odsto, odnosno \u0161est odsto \u2013 ka\u017ee Bejli.<\/p>\n

Bejlijev tim svoju teoriju potkrepljuje i teorijom seks istra\u017eiva?a Reja Blan?arda.<\/p>\n

\u2013 Mu\u0161ki fetusi nose mu\u0161ke specifi?ne proteine na Y hromozomu pod nazivom H-Y antigeni, a ti antigeni unapre?uju razvoj heteroseksualne orijentacije kod mu\u0161karaca \u2013 ka\u017ee Blan?ard.<\/p>\n

Ovi antigeni nisu prirodni u \u017eenskom telu, tako da ?e ih majka koja je trudna sa de?akom do\u017eiveti kao okida? za proizvodnju antitela majke. Ova antitela ?e se, zauzvrat, vezati za HY antigene kako bi ih spre?ila da funkcioni\u0161u i zauzvrat ?e ometati seksualni diferencijaciju mo\u017edanih centara koji posreduju u mu\u0161koj seksualnoj orijentaciji.<\/p>\n

Ako majka drugi put ima mu\u0161ku trudno?u, antigeni u njenom sistemu ?e se pove?ati i podi?i verovatno?u da ?e slede?e dete biti gej.<\/p>\n

Iako iza ove teorije stoje validna nau?na istra\u017eivanja, ni\u0161ta nije stvarno dokazano, a ?injenica da to ne funkcioni\u0161e isto kod \u017eena otvara neka pitanja.<\/p>\n

Na kraju, ima dosta homoseksualaca koji uop\u0161te nemaju stariju bra?u.
