The cryopreservation of epididymal sperm is important to preserve genetic material from valuable deceased males. This study evaluated the viability of sperm samples from eight stallions under three conditions: (1) collected using an artificial vagina (EJ-0h), (2) recovered from the epididymal cauda immediately after orchiectomy (EP-0h), and (3) recovered from the epididymal cauda after 24h of s...

Oxidative stress during freezing-thawing reduces sperm motility, viability, membrane functions and antioxidant capacity. Thymus vulgaris has antioxidant properties due to phenolic compounds. The purpose of current study was to evaluate the effect of Thymus vulgaris extract as a natural antioxidant on post-thawed Moghani ram sperm quality. Semen samples were collected twice a week from four rams...
