Abstract:

Male quails kept in segregation from or in cohabitation with females were injected with 3H thymidine and the passage of labeled spermatozoa through the epididymis and the vas deferens was followed by autoradiography. Labeled spermatozoa appeared in the epididymis on the 11th day after injection and reached the distal part of the vas deferens within 24 hr both in segregated males and in those kept with females. Three sperm populations with decreasing intensity of labeling were identified in the epididymis on days 11, 14 and 15, and in the distal part of the vas deferens on days 12, 15 and 16 after injection. From the distribution of labeled spermatozoa along the vas deferens of the 2 groups, it was concluded that some slowing down in the transit of the main bulk of the spermatozoa had occurred in the males kept isolated from females. This fact indicated the role of the vas deferens as a transitory storage place of the segregated males' unejaculated spermatozoa which were eliminated about 24 hr later than those of the males kept in cohabitation with females.
