Oxidative stress and the retention of excess residual cytoplasm by the spermatozoa are frequently associated with the induction of such damage. The redox cycling of xenobiotics by oxido-reductases in the germline, the patient\u2019s age, the incidence of genital tract infections and Sertoli cell dysfunction are all possible contributors to DNA damage in germ cells. Collateral peroxidation of unsaturated fatty acids in the sperm plasma membrane generally ensures that spermatozoa experiencing severe oxidative DNA damage cannot participate in the process of fertilisation. The adaptive termination of pregnancy through the selective vulnerability of genes involved in placentation may also help prevent the vertical transmission of damaged DNA. However, the ultimate safeguard against this form of damage will be to understand the biochemical basis of oxidative stress in human spermatozoa, so that the underlying causative mechanisms can be addressed in a logical manner.<\/jats:p>","DOI":"10.1071\/rd04083","type":"journal-article","created":{"date-parts":[[2006,12,19]],"date-time":"2006-12-19T18:50:22Z","timestamp":1166554222000},"page":"655-664","source":"Crossref","is-referenced-by-count":61,"title":["Founders\u2019 Lecture.
