Morphometric measurements of the seminiferous tubules of the testes in 2-year-old and 3-year-old European bison males with or without spermiogenesis.

摘要

The area, perimeter and diameter of the seminiferous tubules in the European bison Bison bonasus (L.) were statistically higher in the animals with than in those without spermiogenesis, both among 2-year-old and 3-year-old males (p<0.001; p<0.001; p<0.001).
