1) ureter, 2) ductus deferens, 3) urinary bladder, 4) prostate, 5) urethral muscle, 6) ischiocavernosus muscle, 7) retractor penis muscle, 9) bulbospongiosus muscle, 10) crus penis, 11) ischiocavernosus muscle, 12) retractor penis, 13) sigmoid flexure, 14) free portion of the penis. The penis is attached to the prepuce at birth and does not become free until 2 - 3 years of age (Fig. In the absence of sexual arousal, the small preputial opening is directed caudally and because of this they urinate towards the rear, but when erection of the penis occurs, the cranial prepucial muscles pull the prepuce, and also the penis, forward from their backward position. The prepuce is flattened from side to side and triangular in shape when viewed laterally. In dromedaries, the cauda epididymis is round and well-protruded about 3 - 4 cm above the respective extremity of the testis.ĭuctus deferens - The ductus (or vas) deferens are very long measuring between 45 - 50 cm in length and are enclosed within the spermatic cord. It is located along the dorsal border of the testis with the head curving around the cranial pole of the testis. EpididymisĪs in other species the epididymis is composed of three distinct parts: the caput (head), the corpus (body) and cauda (tail). For example, the estimated production of camel spermatozoa is 8.1 x 10 6 sperm cells per day at the end of Spring and drops to 4.2 x 10 6 sperm cells per day at the end of the Summer. The season does not however have any effect on the size of the spermatozoa although it does on their number. In camels the outer diameter of the seminiferous tubules has been reported to vary between 113 - 250 μm in diameter and gets significantly smaller during the non-rutting season. Testicular size is an important parameter in the evaluation of the breeding potential of males and can be used to predict daily sperm production because of the high correlation found between scrotal measurements testicular weight and total sperm production. They become enlarged and protrude when the male camels are sexually active in the rutting season. This is probably due to differences in age, breed and sexual activity at the time of measuring, but in general they vary in length from 7 - 10 cm and weigh between 80 - 100 g each. They increase in size at the onset of puberty but there has been a wide variation in the dimensions reported. The testes of camels are ovoid in shape and are usually descended at birth but are very small.
#Bulls have sigmoid flexture skin
The scrotal skin tends to be smooth and fine during the height of breeding activity and then becomes thicker during the period of sexual inactivity because of decreased testicular size. The scrotum is located in the perineal region in camels with the testicles directed caudo-dorsally. Anatomy of the External Genetalia Scrotum and Testes
