Nonsense ... unless you can cite the proof of this assertion, as in a way to prove what is 'passed optimal time': "An egg which has been out of the ovary for longer than the optimal time before fertilization ..." I dare you to try. And while you're at it, try proving that the sex act has anything to do with this specious term you toss out, "past-ripe egg". God created a woman's biology such that her uterine lining becomes 'ready to receive' an embryo even before her ovary pops out an ovum, and that uterus remains 'ready' until the lining is shed in the menses (and in some cases even after the shedding has begun).

You really ought to read some actual scientific books on the subject. If you care so much about this subject, one would think you'd want to learn the basics.
