Morphometry of male procine genitalia

Abstract

Biometry of various organs of the male genital system in pigs was studied in 4 normal piglets, 4 normal adults, 4 cryptorchidpiglets, 4 cryptorchid adults and 90 Castrated adults. The testis, epididymis, vesicular and bulbourethral glands were almost1.5 to 2 times in dimensions and 3 times in weights in normal adults pigs than in piglets. the prostate glands measured aboutthe same in piglets and adults in length, breadth and thickness, but were about 2 times in weight in adults (11.3 g). Thepenis measured 350 mm x 6 mm in piglets and 430 mm x 8 mm in adults. In cryptorchid piglets, the testis and epididymisweighed lighter than in their normal counterparts but linear dimensions had remained practically unaffected. The vesicularand bulbourethral glands in cryptorchid piglets did not differ materially from their normal counterparts. The prostate wassignificantly smaller. In the adult cryptorchids measurements of different parts of genitalia did not vary materially fromthose of piglet cryptorchids but were quite small than in normal adults. Penes were not only shorter in piglet and adultcryptorchids but also thinner in adult cryptorchids. In castrated adult pigs the vesicular, prostate and bulbourethral glandswere atrophied. The penes were shorter and thinner (32 cm x 0.5 cm).
