Sugar-sweetened beverage intake in relation to semen quality and reproductive hormone levels in young men

summaryanswer: Higherconsumption of SSB was associated with lower sperm motilityamong healthy, young men. what is known already: The existing literature onthe potentialroleof SSBs onmale reproductivefunctionis scarce and primarilyfocusedontherelationbetweencaffeinatedbeveragesandsemenquality.However,arodentmodelsuggeststhatSSBsmayhampermalefertility. studydesign,size,duration: TheRochesterYoungMen’sStudy;across-sectionalstudyof189healthyyoungmencarriedoutatthe Universityof Rochesterduring 2009–2010. participants/materials,setting,methods: Menaged18–22yearsprovidedsemenandbloodsamples,underwentaphys-icalexaminationandcompletedapreviouslyvalidatedfoodfrequencyquestionnaire(FFQ).Linearregressionwasusedtoanalyzetheassociationof SSBs with sperm parameters and reproductivehormone levelswhile adjusting for potential confounders. mainresultsandtheroleofchance: SSBintakewasinverselyrelatedtoprogressivespermmotility.MeninthehighestquartileofSSBintake(≥1.3serving/day)had9.8(95%CI:1.9,17.8)percentageunitslowerprogressivespermmotilitythanmeninthelowestquartileofintake(,0.2serving/day)(P,trend ¼ 0.03).Thisassociationwasstrongeramongleanmen(P,trend ¼ 0.005)butabsentamongoverweightorobese men (P, trend ¼ 0.98).
