Hyperstimulation (Ovarian Hyperstimulation Syndrome, OHSS)

A potentially life-threatening side effect of Pergonal ovulation induction treatment. Arises when too many follicles develop and hCG is given to release the eggs. May be prevented by withholding the hCG injection when ultrasound monitoring indicates too many follicles have matured.
