Record of reproductive parameters of Sceloporus bicanthalis

Although the preferred temperature (Tpref) optimizes physiological performance, it was found that males require lower temperatures to maintain their fertility. Evaluating spermatic parameters (concentration, motility, viability) and epididymal morphology in males acclimatized to Tpref, the results revealed significant alterations in sperm quality and epididymis.

These findings demonstrate that prolonged exposure to non-lethal warm temperatures severely compromises male reproductive biology.
