Scanning electron microscopy of seminiferous tubules and spermatozoa of rats under conditions of thermal exposure.
Convoluted seminiferous tubules and spermatozoa of albino rats under conditions of thermal exposure were studied by scanning electron microscopy. Exposure at 40 degrees C (in a thermostat) for 1 h caused significant changes in spatial structure of the tubules and spermatozoa. The tubular lumens acquired an irregular shape. The integrity of the spermatid layer was disrupted. The spermatozoon heads were deformed, the tails became bifurcated and convoluted. The appearance of erythrocytes on the spermatid surface attested to impairment of the blood-testis barrier.
