Peripheral blood concentrations of inhibin B are elevated during gonadotrophin stimulation in patients who later develop ovarian OHSS and inhibin A concentrations are elevated after OHSS onset

Ovarian hyperstimulation syndrome (OHSS) is a serious side-effect of controlled ovarian stimulation. Inhibin A and inhibin B, as putative predictors of OHSS development in the same stimulation cycle, were evaluated. A cohort of 428 in-vitro fertilization (IVF) patients was followed. Fifteen patients with severe OHSS were compared with matched (age, follicle number) controls. Serum samples were obtained at five time points from the start of...
