Selection on Sperm Count, but Not on Sperm Morphology or Velocity, in a Wild Population of Anolis Lizards [PDF]
Sperm competition is a widespread phenomenon that shapes male reproductive success. Ejaculates present many potential targets for postcopulatory selection (e.g., sperm morphology, count, and velocity), which are often highly correlated and potentially ...

Radioprotective and Radiomitigative Effects of Resveratrol in Radiation-Induced Reproductive Toxicity in Male Mice [PDF]
Background: Agents with free radical-scavenging functions may act as radiation modifiers, protectors, or mitigators. Methods: We investigated whether supplementation with resveratrol (RSV) in mice, at different times after the beginning of X-irradiation,

Abnormal Human Sperm Parameters Contribute to Sperm DNA Fragmentation in Men with Varicocele [PDF]
Purpose: This study was performed to evaluate and compare threshold sperm parameters and sperm DNA fragmentation index (DFI), and further analyzed whether sperm DFI could be predicted from sperm parameters in men with varicocele.
