  • Title: Reproductive biology: direct delivery of costly sex peptides.
    Author: Gage MJ.
    Journal: Curr Biol; 2005 Feb 22; 15(4):R124-6. PubMed ID: 15723781.
    Abstract:
    Research on seminal fluid proteins is providing fundamental insights into the interactive evolution of male and female reproductive strategies. Two new studies demonstrate, first, how an influential male sex peptide in Drosophila is delivered to the female bound directly onto sperm cells, and second, that its subsequent release has significant reproductive costs for females.
