    Hello,

    These are the relevant details, from research on the Internet:

    * Proportion of male to female sperm cells in the sperm fluid, are almost equal:

    https://www.sjsu.edu/faculty/watkins/sexratio.htm#...

    * A woman can preserve sperm inside her, for between 3 to 5 days: 

    https://www.nhs.uk/conditions/pregnancy-and-baby/g...

    * Female sperm live longer than male sperm inside the woman: 

    https://www.madeformums.com/getting-pregnant/can-y...

    * Male sperm (may) swim faster than female sperm 

    https://www.madeformums.com/getting-pregnant/can-y...

    [Disputed: Male sperm swim faster than female sperm: ] 

    https://www.ncbi.nlm.nih.gov/pmc/articles/PMC14406...

    Taking above into consideration:

    What happens if, upon sexual intercourse, a woman has an egg ready?

    Likelihood is a boy, that is: IF male sperm do swim faster than female sperm !

    What happens if upon sexual intercourse, a woman does not have an egg ready, but preserves the sperm, and then her egg becomes ready within 3 to 5 days?

    Likelihood (increasing as this time goes by) is a girl, because the female sperm live longer than the male sperm.

    I hope this helps.

    Robert.

    F 50% : A child's sex is determined randomly by the sperm.  Each conception is a mutually exclusive event.  History does not determine the specific sperm that fertilizes the egg.
