“…It may also be hypothesized that CuNPs associated changes in the vas deferens could impairs the sperm transport. It is well known that vas deferens has a variety of functions such as sperm storage, transports sperm during emission, produces fluid, and resorbs dead sperm and sperm components (Flannigan & Goldstein, 2018). Thus, our results suggest that CuNPs might interfere with functions of vas deferens.…”

Although the usage of nanoparticles has expanded substantially in recent years, and it causes the detrimental effect on the various organs. CuNPs are widely used in commercial applications. There has been minimal investigation into the possibly harmful effects of CuNPs on the accessory reproductive organs. Thus, the present study aimed to investigate the effect of CuNPs on the male reproductive organs like epididymis, vas deferens, seminal vesicle and prostate of mice. The mice were exposed orally to CuNPs at three doses 10, 100, and 200 mg/kg for 70 days. Our results showed that the organs index of only vas deferens and prostate reduced at 200 mg/kg group compared to the control. However, the histological study showed degenerative changes in the epididymis at higher doses like distortion in the tubules. The sperm parameters were also decreased in the 200 mg/kg CuNPs group. The vas deferens in 100 and 200 mg/kg treatment groups exhibited detachment of luminal epithelium and with a few or no spermatozoa in the higher dose group. The seminal vesicle and prostate also showed degenerative changes like atrophy, hyperplasia, and scant secretary materials. Furthermore, CuNPs also increased the oxidative stress and decreased antioxidant enzymes in vas deferens and seminal vesicles at higher dose. Caput epididymis showed decreased GPx enzymes in all the groups. However, MDA and GPx in corpus, cauda, and prostate did not show any significant variations among all the groups. In conclusion, our results suggest that CuNPs can manifest the detrimental effect of the male accessory organs and epididymis in a dose and tissue dependent manner. Since, detrimental effects were observed only at higher dose, thus, uses of CuNPs would be safe for reproductive organs at lower dose, even for the prolonged duration.
