Figure 4 (a–c) Histopathological results of the testes for the animals in group 4 (recovery). (a) Loosely packed seminiferous tubules in the testes (H&E, ×40). (b) Incomplete recovery of the testes (H&E, ×100). (c) Spermatogenic arrest predominantly at the level of spermatogonium in the testes (H&E, ×400). (a–c) show a reduction/loss of seminiferous tubules bounded by a thin basement membrane and separated by a loose fibrovascularstroma with prominent Leydig cells. Majority of the seminiferous tubules show spermatogenic arrest predominantly at the level of spermatogonium, with only a few tubules showing demonstrable spermatogenic series up to the spermatocytic level. No spermatozoa but many spermatids that are not fully matured are present. This shows that the recovery did not fully restore the levels of spermatozoa.
