Abstract

The objective of this study is to examine the effects of omega 3 treatment on rat sperm chromatin condensation, DNA damage and spermatogenesis after bleomycin, etoposide and cisplatin (BEP) treatment. In this experimental study, 40 male rats were divided into four groups: Control, BEP, Omega 3 and BEP + Omega 3. Sperm chromatin condensation and DNA damage were assessed using aniline blue and acridine orange staining, respectively. Results show that the mean percentage of sperms with excessive histone and DNA damage was significantly increased in the BEP group after 9 weeks as compared to control group (p˂0.001). While, in the BEP + Omega 3 group, the mean percentage of sperm with excessive histone and DNA damage was decreased significantly compared with BEP group (p˂0.001). The testicular histomorphometric analysis indicated that omega 3 has a significant effect on the mean number of spermatogonia, primary spermatocytes, leydig cells and testicular histology properties following BEP treatment. The mean count of aforementioned cells significantly increased after omega 3 treatment compared with the BEP group (p˂0.001). Our data indicated omega 3 may be had beneficial effect for improving chromatin condensation, DNA damage during spermatogenesis and testicular histomorphic properties following BEP treatment. © 2020 Taylor & Francis Group, LLC.
