This study aimed to verify the influence of environmental variations on sperm, physiological parameters and serum testosterone levels in boars. Eight crossbred boars were used (12 and 36 months), subjected to weekly semen collections. The following data were collected: temperature (TA), relative humidity (UA), temperature-humidity index (UTI), concentration, volume, total sperm, spermatic vigor and motility, rectal temperature (RT), scrotal temperature (TE) and serum testosterone levels. The 18 experimental months were divided into quarters: July to September; October to December; January to March; April to June and the breeders were distributed in three age groups 12, 24 and 36 months. Higher TA and ITU averages were recorded in the E2 per...
