Abstract:
Histological examination of the reproductive tract of the male dog failed to identify glandular tissue other than the prostate gland and its disseminated portion. A biochemical study of the three fractions of the ejaculate demonstrates similarities between the first and the third fractions. The composition of three ejaculates collected over 12 hours indicated that storage of prostatic secretion was a possible explanation for the biochemical differences observed. It is suggested that both the first and third fractions originate from the prostate gland.
