ABSTRACT
Ovarian hyperstimulation syndrome (OHSS) is the gravest complication of so-called controlled (far too often uncontrolled) ovarian hyperstimulation (COH) (1). From a perspective of priorities in reproductive medicine in general and assisted reproductive techniques (ARTs) in particular, OHSS is second only to high-order multiple births on the list of adverse outcomes that need to be minimized or completely eliminated.
