[Ovarian hyperstimulation syndrome].

The ovarian hyperstimulation syndrome is the most serious complication following ovulation induction. It is assuming greater clinical importance now that the indication for ovulation induction is no longer limited to anovulatory women but expands to other infertility problems. In its most severe manifestation the ovarian hyperstimulation syndrome consists of massive ovarian enlargement with multiple cysts, hemoconcentration, ascites, and pleural and pericardial effusion. There is no specific treatment and a reduction in the incidence of this iatrogenic syndrome can be achieved only by preventive measures.
