what is the regular size of overy and the time of ovelution?

Answer 1

The ovary is a lot bigger than a "pin top"...

The normal adult ovary measures approximately 3-5 cm in length, 1.5-3 cm in width, and 0.5-1.5 cm in thickness; however, ovarian size is reported more often in terms of volume, or length X width X thickness X 0.523. Normal ovarian volume in the menstruating females is 5-15 mL, with an approximate mean of 10 mL; however, measurements as high as 22 mL have been reported in normal ovaries.

Answer 2

its very small as small a pin top
