<em>An LH spike occurs during oestrogen feedback loop because the pituitary gland positively responds to the high level of oestrogen </em>and produces more LH.
During the ovulatory phase the amount of hormones like oestrogen, follicle stimulating hormone and Leutenising hormone are high. <em>FSH enables the formation of follicles and LH enables the rupture of matured follicle and release of ovum into the oviduct. </em>
In the middle of menstrual cycle when the amount of oestrogen is high pituitary gland give <em>a positive feedback by producing more LH.</em>
<em>This is called LH surge.</em> By this time primary follicles would have matured into graffian follicle and would be holding the ovum. <em>LH surge causes the follicle to rupture and the ovum gets released into the oviduct. </em>
