Seminal reactive oxygen species-antioxidant relationship in fertile males with and without varicocele.

abstract：:Oestrus urine was proved as a potential endocrine modulator in alleviating the toxicity induced by 3-methylcholanthrene (3-MC) in male rats. We, in this study, aimed to prove the attributing potential of toxicity alleviation to squalene, an oestrus-specific pheromone in rats. A single dose of 3-methylcholanthrene (25 ...
