I'll look it up online. I recognize parts of the words, but I can't recall what they mean.
Edit:
You're reading a coroner's report!? Like, a report of a dead human body? Because Endometrium secretory refers to ovulation...
"The presence of secretory endometrium is fairly strong presumptive (but not definitive) evidence of ovulation. "

It is definately perimortem (before death). Only living women can ovulate. It is a natural part of the woman's menstrual cycle.
