The experience of treatment with favorable outcome of 3 patients, in whom gangrene of Fournier was diagnosed, was summarized.The necessity of application of "agressive" surgical tactics in early terms of the disease was stressed.

A prolonged period of daily ejaculations via masturbation may result in an episode of hematospermia, possibly due to stress applied to the vasculature of the reproductive system.

Endothelial cells in the intact adult are, apart from those in the female reproductive organs, believed to be quiescent. Systematic examination of endothelial cell proliferation in male reproductive organs has not been performed and was therefore the aim of the present study. Intact adult rats were either pulse labeled or long-term labeled with bromodeoxyuridine to label proliferating cells. The roles of Leydig cells and testosterone were examined after castration or treatment with the Leydig cell toxin ethane dimethane sulfonate (EDS) and testosterone substitution. After perfusion fixation, all blood vessels remained open and were easily identified. In all male reproductive organs studied, particularly in the testis and epididymis, endothelial cell proliferation was considerably higher than in other tissues such as the liver, brain, and muscle. Proliferating endothelial cells were observed in all types of blood vessels in male reproductive organs, but other characteristics of new blood vessel formation were not seen. High endothelial cell proliferation may reflect a continuous high turnover of endothelial cells rather than classical angiogenesis. In the epididymis, the ventral and dorsolateral prostate lobes, and the seminal vesicles, endothelial cell proliferation decreased after testosterone withdrawal and increased following testosterone treatment. In the testis, endothelial cell proliferation was decreased after Leydig cell depletion but remained low after testosterone substitution. High, hormonally regulated endothelial cell proliferation is not unique to the female but is also seen in the male reproductive organs.

The copulatory apparatus of the male turkey consists of two parts: the Phallus nonprotrudens, composed of the paired Corpora phallica lateralia and Plicae lymphaticae, and the paired Corpora vascularia paracloacalia. The Corpus vasculare paracloacale receives its vascular supply and drainage from the Arteria (A.) and Vena (V.) pudenda interna, respectively, and its innervation from the Nervus pudendus internus. During sexual stimulation lymph produced in the Corpora vascularia paracloacalia rapidly flows through the lymph sinuses into larger lymph channels located in the Phallus nonprotrudens producing tumescence. With detumescence, the lymph flows cranially from Phallus nonprotrudens into the Vasa lymphatica pudenda interna, which parallels the A. and V. pudenda interna.

The anatomical structure of the ejaculatory groove region (EGR) of the drake was investigated macro- and microscopically in connection with its function. The EGR covers a part of the urodeum and the second fold of the cloaca. The EGR is unique to the males and is characterized by red colored appearance and less smooth surface of the mucosa. The mucosa of EGR forms folds giving less smooth surface to it and is lined with psuedostratified columnar epithelium. A vascular layer which contains many capillaries and lymphocytes and gives red color to the mucosa lies just beneath the epithelium. The EGR develops at puberty together with the developments of the testis and the penis. Blood supply and the arrangement of the lymphatic sinuses of EGR were described and their functions were discussed.

The distribution of fibrinolytic activity in the tissues of the male genital tract was studied by a histological technique. Preparations made from testis, epididymis, vas deferens, seminal vesicle, prostate, bulbo-urethral gland, and urethra showed that most activity was related to the blood vessels. However, inconsistent fibrinolytic activity related to epithelium was found in all parts of the genital tract. This epithelial activity was least in the testis, greater in the seminal vesicle and prostate gland, and was greatest in the bulbo-urethral gland and terminal urethra. No fibrinolytic activity could be demonstrated in relation to spermatozoa.
