Summary

This study looked at 40 women with low ovarian reserve (poor response to fertility drugs) to see if flushing the follicle with a special needle helps collect more eggs than just sucking them out. Each woman had one ovary treated with the flushing method and the other with the standard method. The goal was to find out which technique works better for these patients.
