“…For example, in aged rats, degenerative changes have been observed in elastic fibers of the TA, and these could be associated with the lower intracavernosal pressures also found in these aged animals 22 . In humans, the concentration of elastic fibers in the TA decreases with age 18 , which is consistent with a reduction in the extensibility 33 and elasticity 34 of the penis in aged individuals. Although a direct causative role for elastic fibers in erectile dysfunction cannot be established yet, it has been shown nonetheless that their content is decreased in the TA from impotent men 15 , 18 .…”

PURPOSE:To investigate whether elastic fiber content in the corpus cavernosum (CC), corpus spongiosum (CS) and tunica albuginea (TA) of the rabbit penis undergoes modifications with age. METHODS:Rabbits were sacrificed, in groups of ten animals each, at 30, 120, 240, and 730 days of age. Histological sections were obtained from the penile middle shaft and were stained with Weigert's resorsin fuchsin. The content of elastic fibers was determined using stereological methods, and was expressed as volume fraction. RESULTS:At 730 days of age, elastic fiber content was increased by 54% (p<0.004), 78% (p<0.004), and 87% (p<0.004) in the TA, CC, and CS, respectively, compared with animals aged 30 days. After 30 days of age, the concentration gradually and significantly increased until 240 days of age. In 730-day old animals, the concentration, compared with the previous age group, was unchanged in the CC and decreased by 20% (p<0.004) in the TA. CONCLUSIONS:Elastic fiber contents in the rabbit penis correlate with properties of penile tissues. Although after one month of age there is a gradual increase in these concentrations, in two-year old animals this trend is interrupted, which suggests that this could be an early alteration due to senescence.

“…The mean value reported from Jordan 7 (11.8 cm) is found to be significantly low. Bondil et al 10 reported the longest penile length in the flaccid (10.7 cm) and stretched conditions (16.24 cm). In their study, measurements were obtained after three manual stretches of the penis.…”

Apprehension about the normal size of penis is a major concern for men. Aim of the present investigation is to estimate the penile length and circumference of Indian males and to compare the results with the data from other countries. Results will help in counseling the patients worried about the penile size and seeking penis enlargement surgery. Penile length in flaccid and stretched conditions and circumference were measured in a group of 301 physically normal men. Erected length and circumference were measured for 93 subjects. Mean flaccid length was found to be 8.21 cm, mean stretched length 10.88 cm and circumference 9.14 cm. Mean erected length was found to be 13.01 cm and erected circumference was 11.46 cm. Penile dimensions are found to be correlated with anthropometric parameters. Insight into the normative data of penile size of Indian males obtained. There are significant differences in the mean penile length and circumference of Indian sample compared to the data reported from other countries. Study need to be continued with a large sample to establish a normative data applicable to the general population.
