Understanding Ovarian Hyperstimulation Syndrome (OHSS): Causes & Prevention

During the ovarian stimulation phase of an IVF cycle, the clinical goal is to encourage the ovaries to develop multiple healthy egg follicles. While this process is highly successful, some patients respond strongly to hormonal injections. If you are preparing for your stimulation phase, understanding the causes and warning signs of ovarian hyperstimulation syndrome (OHSS) is essential to ensuring a safe and comfortable treatment.

This comprehensive guide details the physiology of hyperstimulation, compares mild and severe symptoms, and outlines the advanced clinical protocols used to prevent OHSS.

OHSS Risk Factors and Clinical Protocols

OHSS is triggered by hCG triggers. PCOS patients are at higher risk (read details in our PCOS guide and PCOS vs PCOD guide) as are high AMH reserves (read our ovarian reserve AMH guide). Prevent it using mild stimulations (read details in our mini IVF guide) and freeze-all protocols (read about outcomes in our successful implantation guide).

Ensure a Safe IVF Stimulation Cycle
Preventing OHSS is a primary focus of modern, patient-first IVF protocols. If you want to check your follicle parameters or discuss customized stimulation calendars, you can schedule a fertility consultation at Pravi Global IVF.

OHSS Frequently Asked Questions (FAQ)

1. How long does mild OHSS last?
Mild symptoms typically begin 3-7 days post retrieval and resolve in 7 to 10 days.

2. Can I drink water if I have OHSS?
Electrolyte fluids are preferred over plain water to manage pelvic fluid shifts.

3. How can I prevent OHSS at home?
Eat high-protein foods, drink electrolytes, and monitor weight daily.

4. Does having OHSS affect egg quality?
No, hyperstimulation does not reduce egg quality or embryo viability.

5. Why does a "Freeze-All" cycle prevent OHSS?
It avoids transfer and pregnancy, preventing the hCG rise that triggers fluid leakage.
