title: [Importance of the testicular artery: histo-functional approach and comparison between juvenile and adult rats].
abstract: The aim of this study is to demonstrate the role of spermatic or testicular artery with regard to fertility. 100 male rats Sprague-Dawley, consisted of 50 young rats (aged from 10 to 12 days old) and 50 adult rats were concerned. Unilateral ligation of the testicular artery with delayed controlateral orchiectomy were performed in 20 young rats. Only unilateral orchiectomy was planned in 20 other young rats and the 10 remaining were the absolute control group. Mating was observed for 2 weeks after 14 weeks of life. In adult rats, 20 underwent a bilateral ligation and division of the spermatic artery while 20 others were submitted to unilateral ligation-division associated with controlateral orchiectomy in 20 others. The 10 remaining represented the control group. The mating period was 3 weeks. After sacrificing animals, results were noted with regard to histological features and fertility. Among young rats, 45% were fertile and had normal gonadal tissue. From adult rats, only 10 to 15% were fertile. Atrophic testes were observed in 55% of infertile young rats while acute inflammatory lesions were predominant in most of adults. We conclude that ligation or division of spermatic artery is responsible for histological changes thus occurring in infertility in young and adults rats.
