The physiological mechanism underlying the photo-stimulation is that an increase in photoperiod elevates the rate of secretion of gonadotrophin-releasing hormone (GnRH), leading to elevated gonadotrophin secretion, and hence gonadal maturation such as luteinizing hormone (LH) and follicule hormone (FSH), which in turn induce gonad growth and steroid hormone production (Wingfield and Farner, 1993).

IVM treatment typically involves a relatively short duration of gonadotrophin stimulation and the retrieval of oocytes from follicles at a much smaller diameter than with conventional IVF treatment, often without the use of a trigger injection and oocyte maturation occurs in vitro [4].
