Bacriminta sare ee ninka (Male Fertility) ma aha wax laga arki karo indhaha oo kaliya, laakiin cilmi-baarista caafimaadka ayaa xaqiijisay in calaamado gaar ah oo dhanka jirka, dabeecadda, iyo caafimaadka guud ah ay muujin karaan heerka sare ee hormoonka Testosterone iyo tayada unugyada taranka.
1. Codka oo Culus (Deep Voice)
Cilmi-baaris ay samaysay jaamacadda Western Australia ayaa muujisay in ragga leh codka culus ay badanaa leeyihiin heer sare oo Testosterone ah. In kasta oo codka aadka u culus mararka qaar lala xiriiriyo tirada shahwada oo xoogaa yaraata, haddana wuxuu calaamad u yahay ragannimo iyo awood dhanka hormoonnada ah.
2. Wareegga dhexda oo yar (Waistline)
Ninka leh caloosha fidsan (aan lahayn baruurta caloosha) wuxuu u dhow yahay inuu lahaado bacrimin sare. Baruurta caloosha ku ururta waxay soo saartaa hormoonka Estrogen kaas oo burburiya hormoonka Testosterone, hoosna u dhiga tayada taranka.
3. Wajiga oo u samaysan qaabka labka (Jawline)
Dhabannada xooggan iyo daanka (jawline) u samaysan qaabka labka ah ee labajibbaaran ayaa calaamad u ah heerka sare ee Testosterone-ka. Hormoonkan ayaa ah midka maamula soo saarista unugyada taranka ee caafimaadka qaba.
4. Muruqyada iyo Jirka oo dhisan
Ninka jirkiisu si dabiici ah u dhisan yahay, lehna muruqyo muuqda xitaa haddii uusan jimicsi badan samayn, wuxuu leeyahay nidaam hormoon oo aad u shaqaynaya, taas oo si toos ah u kordhisa awoodda bacriminta.
5. Timaha Jirka (Body Hair)
In kasta oo ay ku xiran tahay hidda-sidaha, haddana ragga leh timaha jidhka (sida xabadka iyo gadhka) ee u baxa si habka labka ah waxay muujinayaan inay leeyihiin dareen-celin wanaagsan oo xagga hormoonnada ragga ah.
6. Faraha Gacanta (Digit Ratio)
Cilmi-baaris dhanka bayoolajiga ah ayaa sheegaysa in haddii farta fargashiga (ring finger) ay ka dheer tahay farta murdisada (index finger), ay calaamad u tahay in ninkaas uu helay testosterone badan xilligii uu uurka hooyada ku jiray, taas oo lala xiriiriyo bacrimin sare marka uu weynaado.
7. Dhaqdhaqaaqa iyo Tamarta (High Energy)
Ninka leh tamar sare, firfircooni, iyo niyad dhisan wuxuu leeyahay nidaam dheefshiid iyo mid wareeg dhiig oo wanaagsan. Dhiigga oo si fiican u gaara xubnaha hoose wuxuu muhiim u yahay wax soo saarka unugyada taranka.
8. Hurdada raaxada leh
Ragga seexda hurdo tayo leh (7-8 saacadood) waxay leeyihiin bacrimin ka sarreysa kuwa hurdada ku dhibtooda. Testosterone-ka badankooda waxaa la soo saaraa xilliga hurdada ee habeenkii.
9. Miisaanka oo dheellitiran
Cayilka xad-dhaafka ah ama caatada aadka u daran labaduba waxay saameeyaan tayada unugyada taranka. Ninka miisaankiisu yahay midka caadiga ah (Normal BMI) wuxuu u dhow yahay inuu yeesho bacrimin aad u sarraysa.
10. Qanjirrada (Testicles) oo caafimaad qaba
Mugga iyo xajmiga qanjirrada taranka ayaa door weyn ka ciyaara. Haddii ay yihiin kuwo adag oo leh xajmi caadi ah, waxay soo saari karaan unugyo badan oo taran. Haddii ay jiraan xididdo bararsan (Varicocele), waxay hoos u dhigi kartaa bacriminta.
