Effect of increased testicular temperature on seminal plasma proteome of the ram.

The present study evaluated the effects of heat stress on the ram seminal plasma proteome. Six Morada Nova rams were scrotal insulated for 8 days. Scrotal circumference, sperm parameters, and seminal fluid proteins were evaluated before (Day 0) and twice during scrotal insulation (Days 4 and 8), and weekly until semen parameters returned to preinsulation values (normal).
