excessive stimulation of the ovaries that can cause them to become enlarged
The over-stimulation of the ovaries during IVF drug treatment.
A potentially life-threatening side effect of ovulation induction with injectable fertility medications such as hMG and urofollitropins. A woman's ovaries become enlarged and produce an overabundance of eggs. Blood hormone levels rise, fluid may collect in the lungs or abdominal cavity, and ovarian cyst may rupture, causing internal bleeding. Bloodclots sometimes develop. Symptoms include sudden weight gain and abdominal pain. Cycles stimulated with these drugs must be carefully monitored with ultrasound scans. OHSS may be prevented by withholding the hCG injection when ultrasound monitoring indicates that too many follicles have matured.
