The rupture of the mature (graafian) ovarian follicle during ovulation is stimulated by a surge in the secretion of

Lutenising hormone (LH)

Explanation:

Follicle stimulating hormones (FSH) are released by pituitary gland as the follicle develops. As the follicle matures, the level of oestrogen increase thereby suppressing the release of FSH. A hormone named inhibin also suppresses the production of FSH. The rise in level of Oestrogen triggers the release of Lutenising hormone which is responsible for ovulation. LH causes the follicle to rupture and thus lutenise it to form corpus luteum.
