Mammalian reproductive tract mucins.

abstract：:In the male genital tract, reactive oxygen species (ROS) are generated by spermatozoa and leukocytes including neutrophils and macrophages. ROS are involved in the regulation of sperm functions such as capacitation and the acrosome reaction. Infections lead to an excessive ROS production, resulting in an 'oxidative bu...
