Ovarian Hyperstimulation Syndrome - a potentially serious complication of fertility treatments causing enlarged ovaries and fluid accumulation.
Full Definition
Ovarian Hyperstimulation Syndrome is an iatrogenic complication that can occur after ovulation induction or controlled ovarian stimulation. It is characterized by enlarged ovaries, increased vascular permeability, and fluid shifts leading to ascites, pleural effusion, and electrolyte imbalances. OHSS ranges from mild to severe, with severe cases requiring hospitalization for monitoring and supportive care. Risk factors include young age, PCOS, high AMH levels, and previous history of OHSS. Prevention strategies include cycle cancellation, coasting, or using GnRH antagonist protocols.
