  • Title: Genital evolution: the traumas of sex.
    Author: Hosken DJ, Price TA.
    Journal: Curr Biol; 2009 Jul 14; 19(13):R519-21. PubMed ID: 19602415.
    Abstract:
    Copulating males usually insert their penis into the female and ejaculate in her reproductive tract; but in some species, males are more invasive, puncturing the female body-wall and inseminating directly into her body-cavity. A spider has just been added to this list and new perspectives provided on why males harm females during copulation in the first place.
