* One follicle normally obtains dominance and subsequently ovulates.
* One follicle normally obtains dominance and subsequently ovulates.
* Dominance does not involve inhibin. It is probably due to an intra-ovarian mechanism which does not suppress FSH secretion. Other hormones such as IGF-1 (Insulin-like growth factor-1) may also be involved in follicular growth patterns.

* During dioestrus, there are several large follicles on the ovary. These range in size 0.7-1.5cm in diameter. These follicles do not alter the contours of the ovaries, but cause variation in size.

* During Pro-oestrus and oestrus, the dominant follicle enlarged and ovulation occurs once it is at least 1.9cm.
