Generation of reactive oxygen species, lipid peroxidation, and human sperm function.
Recent studies have demonstrated that human spermatozoa are capable of generating reactive oxygen species and that this activity is significantly accelerated in cases of defective sperm function. InExpand

Cellular basis of defective sperm function and its association with the genesis of reactive oxygen species by human spermatozoa.
Addition of the divalent cation ionophore, A23187, to washed populations of human spermatozoa resulted in a sudden burst of production of reactive oxygen species which peaked within 3-5 min. ThisExpand

Relative impact of oxidative stress on the functional competence and genomic integrity of human spermatozoa.
Reactive oxygen metabolites are known to disrupt sperm-oocyte fusion, sperm movement, and DNA integrity; however, the relative sensitivities of these elements to oxidative stress are unknown. In thisExpand

Polyunsaturated Fatty Acids in Male and Female Reproduction1
Abstract In Westernized societies, average consumption of n-6 polyunsaturated fatty acids (PUFAs) far exceeds nutritional requirements. The ratio of n-6 to n-3 PUFAs is generally >10:1 whereas on aExpand

DNA integrity in human spermatozoa: relationships with semen quality.
The literature contains conflicting evidence regarding the existence of DNA damage in spermatozoa from infertile male patients. To examine this phenomenon, we have studied ejaculated spermatozoa fromExpand
