Changes in basal lamina of seminiferous tubules associated with deranged spermatogenesis in the bull.
Am J Vet Res 1987; 48(2):243-5AJ

Abstract

The basal lamina of seminiferous tubules of 16 beef bulls, with scrotal circumferences (SC) from 40.5 to 28 cm, was characterized. The mean thickness of basal laminae was from 0.55 to 0.94 micron in normospermic bulls with SC greater than 30 cm. Of 3 bulls that had a SC less than 30 cm, 1 had hypoplastic testes and was azoospermic, whereas 2 bulls had atrophic changes in their testes and were oligospermic. The latter 2 bulls had thick basal laminae, with a mean of 1.35 micron and 1.68 micron, respectively, whereas basal laminae of the bull with hypoplastic testes had a mean thickness of 0.96 micron, comparable with that of bulls with normal testes (SC, greater than 30 cm). Thickness of the basal lamina of seminiferous tubules might be a useful criterion in differentiating atrophy from hypoplasia.
