Frequently Asked Questions

Who is at risk of developing OHSS?

Women undergoing fertility treatments, particularly those using gonadotropin hormones, are at higher risk. Younger women and those with polycystic ovary syndrome (PCOS) are also more susceptible.

Can OHSS be prevented?

Prevention strategies include careful monitoring during fertility treatments, adjusting medication dosages based on ovarian response, and considering alternative protocols in high-risk patients.

How long does OHSS last?

Mild cases of OHSS usually resolve within a few days to weeks. Severe cases may take longer to resolve and require medical intervention.

Can OHSS affect future fertility?

In most cases, OHSS does not affect future fertility if managed appropriately. However, severe cases may lead to complications that could impact ovarian function.

What is the success rate of ovarian hyperstimulation?

The success rate of ovarian hyperstimulation varies widely but generally ranges from 10% to 60% per treatment cycle, influenced by factors like age and underlying fertility issues.
