A group of 224 men aged 65-90 years, randomly selected from the group of 5695 persons included in the PolSenior project was studied. We established genotype prevalence of the vitamin D receptor gene polymorphisms (TaqI rs10735810, ApaI rs1544410, BsmI rs7975232, FokI rs731236) and testosterone serum concentration levels. Polymorphisms were divided into two models: protective (Taq TT genotype, Apa aa genotype, Bsm genotype BB, Fok genotype FF) and risk (Taq tt genotype, Apa AA genotype, Bsm genotype bb, Fok genotype ff). The cumulative effect of these two models on the concentration of testosterone were calculated.
