post-insemination sperm bias

[Rodney Adams]

Following insemination, is there anything which could affect the survival
rates or ratios of X versus Y chromosome sperm?  For instance, might the 
abundance of androgens or estrogens affect the likelihood of an X or a Y
chromosome sperm successfully fertilizing the ovum?

Just curious....
