Defective Human Sperm Cells Are Associated with Mitochondrial Dysfunction and Oxidant Production1

Abstract excerpt

Infertility affects about 15% of couples of reproductive age. The male factor is involved in nearly 50% of infertility cases. Defective human sperm function has been associated with evidence of high levels of reactive oxygen species (ROS) and a resultant loss of fertilizing potential in vivo and in vitro. Analogous to what has been observed in somatic cells, mitochondria are likely the major sources of ROS in...
