The Cochrane Menstrual Disorders and Subfertility Group has prepared nearly 200 reviews, and continues to investigate new aspects of treatment and care. In February 2014, a new review from a team in The Netherlands and New Zealand looks at the use of aromatase inhibitors for subfertile women with anovulatory polycystic ovary syndrome. Lead author, Sebastian Franik from Radboud University in Nijmegen, describes their findings.
