Аннотация
Unilateral orchiectomy was performed on 9 mature mixed-breed bulls with satisfactory semen quality to study the effect of the procedure on quality of semen from the contralateral testicle. Semen was collected by electroejaculation before surgery and on alternate days for 2 weeks, then once weekly for 8 weeks. Each sampling day, progressive motility and morphologic features of spermatozoa were determined, and scrotal thermograms were taken. The percentage of normal spermatozoa decreased significantly (P less than 0.05) only on postoperative day 6. Progressive motility scores varied but at the end of the study there was no significant difference from preoperative values. Scrotal thermography revealed inflammation in the contralateral side of the scrotum, beginning 3 days after surgery, but the thermograms were normal in most bulls by 3 weeks after surgery, and all thermograms were normal by 4 weeks.
