When the follicle is about to be expelled, not all follicles are round, but may also be oval, which is a flattened condition. Clinically, ovulation can be diagnosed if the follicle has ruptured and after expulsion of the egg, the collapse is found locally in the follicle by ultrasound, in the uterine rectal trap, with fluid accumulation, which is the flow of follicular fluid to a lower position in the body, in the uterine rectal trap, where fluid accumulation is seen. It can be understood that if the follicle is more round, the greater the tension, and if the follicle is more flat, it means that the tension is not much, and the possibility of ovulation will be relatively lower in clinical terms.
