Abstract
The elderly population is increasing rapidly all over the world and aging is accompanied by an increase in illness and disability. The task is to ensure that all older people enjoy, maintain or regain the highest quality of life and health and to compress major illness and disability into a narrow range. It is within this context that testosterone substitution may play a role (Vermeulen, 2000).
Measurement of penile length has been raised to address the concerns of men regarding their normality in response to relative dissatisfaction with phallus dimensions requesting surgical enhancement.
The aim of this study was to assess penile length among aged males and its relation to their serum level of testosterone hormone (total and free).The present study was conducted on 103 males. They were classified into 3 age groups with an age ranged from 50 to 85 years with a mean 61.78 ± 7.88 years.
SPL was measured by using a ruler with millimeters markings along the dorsum of the penis by compressing suprapubic fat tissue with one end of the ruler, then penis was fully stretched. The distance from pupopenile junction to the tip of the glans was measured and recorded. The serum level of TT and FT were determined for all included patients. Morning venous blood samples were drawn between (8-11 a.m.).
The obtained results showed that SPL ranged from 9-15 cm and the mean value was 12.48 ± 1.70 cm. There was a non-significant statistical difference on comparing SPL with increasing age.
As regarding the level of serum TT and FT among the studied groups, we found that there was significant decrease in both with increasing age.
Moreover, concerning to the correlation between SPL and serum level of TT and FT, it was non-significant.
Finally, on comparing ED with TT and FT and a significant decrease was found in TT and FT on comparing them with non-symptomatic and symptomatic males.
