Female Choice For Males With Competitive Sperm
Female factors can influence the result of sperm competition through a process known as "sperm choice". Proteins present in the female reproductive tract or on the surface of the ovum may influence which sperm succeeds in fertilizing the egg. During sperm choice females are able to discriminate and differentially use the sperm from different males. One instance where this is known to occur is inbreeding; females will preferentially use the sperm from a more distantly related male than a close relative.

Famous quotes containing the words female, choice, males and/or competitive:
“I am obnoxious to each carping tongue
Who says my hand a needle better fits,
A poet’s pen, all scorn, I should thus wrong;
For such despite they cast on female wits:
If what I do prove well, it won’t advance,
They’ll say it’s stolen, or else it was by chance.”
—Anne Bradstreet (c. 1612–1672)
“Come and take choice of all my library,
And so beguile thy sorrow.”
—William Shakespeare (1564–1616)
“Men are rewarded for learning the practice of violence in virtually any sphere of activity by money, admiration, recognition, respect, and the genuflection of others honoring their sacred and proven masculinity. In male culture, police are heroic and so are outlaws; males who enforce standards are heroic and so are those who violate them.”
—Andrea Dworkin (b. 1946)
“Women of my age in America are at the mercy of two powerful and antagonistic traditions. The first is the ultradomestic fifties with its powerful cult of motherhood; the other is the strident feminism of the seventies with its attempt to clone the male competitive model.... Only in America are these ideologies pushed to extremes.”
—Sylvia Ann Hewitt (20th century)
