Prevention of OHSS

We have published the largest study in the literature for women with PCOS undergoing IVF. Our results show that the GnRH antagonist protocol is associated with a significantly lower incidence of OHSS compared to the long protocol, while maintaining high pregnancy rates. Therefore, the antagonist protocol can be the protocol of choice for PCOS women undergoing IVF.

In another study of our team, we used a different antagonist protocol (D1), which was also associated with a lower chance of OHDD development. The study included women with PCOS and compared the long protocol with an antagonist protocol in which antagonist was initiated on day 1 of ovarian stimulation, instead of day 6.

We also use methylprednisolone for the prevention of OHSS in high risk patients. Using this method we successfully treated all cases of OHSS at an outpatient level. Patients with severe OHSS who were hospitalized were very few.
