Volume Two advances the exploration of the fundamental principles of oxidative stress and toxicity on male (and female) reproduction. It includes the advances in research on male reproductive health, the impact of environmental factors, the protective measures using bioactive compounds and traditional medicines, and how to limit toxic exposure. It includes coverage of: - Oxidative stress and male infertility Environmental stressors and sexual health Heavy metals, pesticides, fine particle toxicity and male reproduction Protective measures against oxidative stress in gametes/embryos by using bioactive compounds/phytomedicines in Assisted Reproductive Technology (ART) Role of reactive oxygen species on female reproduction Radiation and mutagenic factors affecting the male reproductive system Both volumes provide a comprehensive look at the most basic concepts and advanced research being conducted by world famous scientists and researchers in male infertility and reproduction.
