[The "aging" of the male genital system: erection].

: Between 1/2/89 and 31/1/92 we have studied 300 old patients (the average patient age was 72 years). We used scores of sexual functionality to study the accordances between voluntary and spontaneous erection, the characteristics of the erection per age, the frequency of intercourse per age, the sexual preferences in males and females. Also the partner's extrangement has been valued. These factors together with the socio-economic conditions, in the same body causes represent an important obstacle in the sexuality of the old man.
