Abstract

A study was conducted to record the morphogenesis of penis in prenatal goat. Seventy embryos/ foeti ranged from 23days to full term were collected from the gravid uteri of apparently healthy goats, obtained from a local abattoir. The approximate age of embryos/foeti was computed and was divided into five groups. At 23 days of gestation, the external genitalia appeared in the form of a cone shaped projection known as genital tubercle, ventral to the cloacal opening and flanked by pelvic limbs. At 30 days of gestation, the tubercle became elongated and directed ventrally where it was bounded on either side by urethral plates. With the increase in gestation period, the genital tubercle became more erected and the urethral plates became thicker to form the urethral folds. At 42 days of gestation the tubercle began to migrate along the abdominal wall towards the umbilicus. The rounded tip of the tubercle had a constriction in its ventral side indicating the beginning of formation of future glans. An anogenital raphe was formed at 48 days of gestation. At 55 days of gestation all the three muscles viz; bulbuspongiosus, ischiocavernosus and retractor penis were distinct. At 72 days of gestation the glans reached closed to the umbilicus. The proximal part of the sigmoid flexure was formed on 78th day of gestation. Both the curves of flexure were formed on 98 days of gestation. On 65th days onwards all the three parts of penis i.e. root, body and glans were distinct.
