Hi,
If you're asking about the peak period for fertilisation, once
ovulation occurs its only about 48 hours (before the peak
fertilisation 'window' closes)....case-to-case basis, some less,
some more.
For most people, ovulation usually occurs 13-14 days after the
first day of your period (also case-to-case basis).
I have to clarify....I'm talking about humans hor? Also, what kind
of egg is not female?
