Multiple deleterious effects of experimentally aged sperm in a monogamous bird
Joel White, Richard H. Wagner, F. Helfenstein, Scott A. Hatch, Herve Mulard, Naves. Liliana, Etienne Danchin
2008, PNAS (105) 13947-13952
Sperm aging is known to be detrimental to reproductive performance. However, this apparently general phenomenon has seldom been studied in an evolutionary context. The negative impact of sperm aging on parental fitness should constitute a strong selective pressure for adaptations to avoid its effects. We studied the impact of sperm...
