Sperm number trumps sperm size in mammalian ejaculate evolution.

Proceedings. Biological sciences - 22 Nov 2015

Lüpold Stefan, Fitzpatrick John L

Abstract excerpt

Postcopulatory sexual selection is widely accepted to underlie the extraordinary diversification of sperm morphology. However, why does it favour longer sperm in some taxa but shorter in others? Two recent hypotheses addressing this discrepancy offered contradictory explanations. Under the sperm dilution hypothesis, selection via sperm density in the female reproductive tract favours more but smaller sperm in...
