Ovarian hyperstimulation syndrome: iatrogenic development of ovarian hyperstimulation that occurs when the luteotropic effects of human chorionic gonadotropin are exaggerated in a cycle in which ovarian stimulation has been done as a component of infertility treatment. The human chorionic gonadotropin is administered exogeneously to trigger ovulation after gonadotropin stimulation. It is present endogenously after implantation. Syndrome includes, to varying degrees, abdominal distention, potentially massive ovarian enlargement, and third spacing of vascular volume. It can range from moderate discomfort to life-threatening ovarian enlargement and fluid shifts.

Ovarian hyperstimulation syndrome: Syndrome composed of a combination of ovarian enlargement and an acute fluid shift out of the intravascular space. The enlargement is caused by ovarian cyst formation and the fluid shift may result in ascites, hydrothorax, or generalized edema. The syndrome is most usually seen as a complication of ovulation induction, a treatment for infertility.

Ovarian hyperstimulation syndrome: A complication of OVULATION INDUCTION in infertility treatment. It is graded by the severity of symptoms which include OVARY enlargement, multiple OVARIAN FOLLICLES; OVARIAN CYSTS; ASCITES; and generalized EDEMA. The full-blown syndrome may lead to RENAL FAILURE, respiratory distress, and even DEATH. Increased capillary permeability is caused by the vasoactive substances, such as VASCULAR ENDOTHELIAL GROWTH FACTORS, secreted by the overly-stimulated OVARIES.
