Abstract

Background:

Epidemiological studies have shown that elevated levels of air pollutants are associated with various adverse health effects, including infertility.

Objective:

We aimed to assess the protective effects of aqueous Urtica dioica leaf extract against benzo[a]pyrene -induced oxidative damage in mouse testis.

Methods:

Mice exposed to benzo[a]pyrene were treated with or without aqueous Urtica dioica extract for five weeks, and changes in body and testes weights, messenger RNA levels and activities of antioxidant enzymes, plasma testosterone levels, sperm characteristics, and testicular tissue histology were determined.

Results:

Exposure to benzo[a]pyrene remarkably reduced testis and body weights, the expression and activity of antioxidant enzymes, increased lipid peroxidation, decreased plasma testosterone levels and sperm count and motility, affected sperm morphology and viability, and damaged the seminiferous tubules. Treatment with aqueous Urtica dioica leaf extract attenuated benzo[a]pyrene -induced oxidative stress in the testicular tissue by increasing the expression of antioxidant genes. Further, Urtica dioica leaf extract reduced lipid peroxidation, increased antioxidative enzyme activity, enhanced sperm characteristics, increased plasma testosterone levels, and improved the morphology of the seminiferous tubules.

Conclusion:

Aqueous Urtica dioica leaf extract protects testicular tissue from benzo[a]pyrene -induced oxidative damage and could potentially reverse benzo[a]pyrene -induced infertility.
