The role of Kisspeptin levels in polycystic ovary syndrome: a systematic review and meta-analysis

Polycystic ovarian syndrome (PCOS) is a complex and not fully elucidated pathology. This prevalent endocrinopathy affects patients in reproductive age, impacts on estrogen-dependent diseases, as well as in infertility. In this context, Kisspeptin (KP) may be considered a potential biomarker for PCOS diagnosis and follow-up. Here, we aimed to verify the levels of KP in obese and non-obese patients with PCOS, their relationship with other hormones, in comparison to healthy controls.
