RESUMEN
Foreign body on penis is usually put himself or by his female partner by adults for sexual gratification and in children as an innocent childish play. We have managed a 10 years shepherd who put on a bark of tree with successful outcome which is not being reported in literature.

The functional organisation of the epididymis has been studied in 20 adult albino rats. The gross divisions of Caput or head, Corpus or body, and Cauda or lower end show distinctive features which indicate functional specialisation. The Caput epididymis has strikingly tall columnar cells with a mean height of 124 mu, but little muscle tissue. It seems to be adapted as a distensible low-pressure reservoir to accomodate the testicular outflow and modify it by absorption and secretion; the prominent stereocilia (or microvilli) would favour this absorptive function. The Cauda, on the other hand, shows abundant muscle tissue around the widening duct and provides the mechanism for rapid delivery of sperms during ejaculation. The Corpus or middle part is peculiarly long and slender, accomodating only 2 or 3 ductules side-by-side. It might serve to separate the two functionally different upper and lower parts and protect the testis against any undue back-pressure. The epididymis weighed 67% of the corresponding testis, on an average. The capacity of the testis to tolerate any obstruction of the outflow tract might be related to the size and capacity of the epididymis in that species.

Total Leydig cell volume has been quantitatively determined by a histometric point-counting method in six common mammals, including man. Although the size of the testis has increased from 1.3 +/- 0.1 ml in the rat to 19.8 +/- 6.9 ml in the buffalo, the composition has remained fairly constant with the Leydig cells making up 9--16% of the testicular volume. In absolute terms, the Total Leydig Volume has increased progressively with body size, from 0.11 +/- 0.02 ml/testis in rat to 2.44 +/- 0.64 ml/testis in buffalo, the value for man being 2.21 +/- 0.40 ml/testis. The significance of these findings, from the point of view of the comparative physiology of male reproduction, has been discussed.
