Preventing OHSS in IVF: Key Strategies for Patients

Ovarian hyperstimulation syndrome (OHSS) affects 1-5% of IVF cycles, causing fluid buildup and discomfort. Risk factors include young age, PCOS, and high AMH levels. Using a GNRH agonist trigger instead of HCG reduces OHSS risk without significantly lowering pregnancy rates.

Key Takeaways

OHSS Risk Factors: Identifying High-Risk Patients in IVF

Women under 30, with BMI <25, antral follicle count >20, AMH >5 ng/mL, PCOS history, or prior OHSS are at highest risk. These patients require tailored protocols to mitigate complications.

Dietary Strategies to Mitigate OHSS in High-Risk Patients

High-sodium (1000+ mg) and high-protein (25+ g) diets post-retrieval, along with electrolyte-rich fluids, may reduce ascites. Surprisingly, a McDonald’s double cheeseburger meets these nutritional requirements.

GNRH Agonist Trigger: Effective OHSS Prevention in IVF

Using Lupron instead of HCG for egg maturation avoids VEGF-driven OHSS but requires embryo freezing due to uterine lining disruption. It’s ideal for antagonist protocols and responsive pituitaries.

Combination Trigger Approach: Balancing OHSS Risk and Pregnancy Rates

A GNRH agonist paired with a small HCG dose preserves endometrial receptivity while reducing OHSS risk. This hybrid method normalizes pregnancy rates compared to GNRH alone.

Medications for OHSS Prevention: Cabergoline and Metformin

Cabergoline (a dopamine agonist) and Metformin reduce severe OHSS incidence without compromising pregnancy outcomes. These are often used when embryos are frozen to avoid fresh cycle risks.
