Fig. 6

Influence of applied protocols on different parameters observed in this study. Morphometric parameters showed in this figure: diameter, cross-section area and height of epithelium refer to seminiferous tubules. Nandrolone group (T-N+), swimming training group (T+N-) and swimming training with nandrolone group (T+N+). ↓ represents decrease; ↑ represents increase; - represents no alteration in comparison to control group (T-N-) (T denotes training, N denotes nandrolone)
