I' ve just purchased an ultrasound machine and I will like to know more about the actual size of follicles? What is the rate at which it grows, what size should they be before I introduce my male and what size does the follicles become developing ovums? I have a female that is showing sighns that she is gravid, rotated with her belly exposed, but when I ultrasound her the follicles are around 17mm in diameter.
