Waxa jira in ka badan 262 qoraal oo cilmi ah oo baranaya saamaynta cuntooyinkan uurka ku leeyihiin.¹ : midna ma muujin kororka cilladaha waaweyn carruurta, iyo mid ka mid ah oo kaliya ayaa muujiyay khatar yar oo kordheysa oo ah hypostadias (xumaanta guska) ee ilmaha labka ah ee hooyada khudradda ah. Shan cilmi baaris ayaa muujisay miisaanka dhalashada hoose ee carruurta ay dhaleen hooyooyinka khudradda, laakiin laba daraasadood ayaa muujiyay natiijooyin liddi ku ah. Muddada uurka, dhanka kale, waa isku mid haddii aad tahay khudrad iyo haddii kale.

Sagaal daraasadood ayaa si kastaba ha ahaatee iftiimiyay khatarta fitamiin B12 iyo yaraanta birta ee haweenka khudradda leh ee uurka leh. Ugu dambeyntii, cuntooyinka vegan iyo khudradda ayaa loo tixgelin karaa inay badbaado yihiin, ilaa inta fiiro gaar ah la siinayo baahida fiitamiinada (gaar ahaan fitamiin B12) iyo walxaha raadraaca (gaar ahaan birta). Cilmi-baaris kale ayaa muujisay in khudradda uurka leh ay si fiican u qaataan qaadashada magnesium, taas oo si weyn u dhimi karta inta jeer ee xanuunka kubka ee saddexda bilood ee saddexaad.².
