Double Stimulation (Duo Stim) is an advanced technique in in vitro fertilization (IVF), primarily used for women with a diminished ovarian reserve or those seeking to maximize their chances of pregnancy. Instead of undergoing two separate cycles, Double Stimulation involves two phases of ovarian stimulation within a single menstrual cycle, aiming to retrieve a higher number of eggs.

This approach allows for the collection of more eggs from women with a low ovarian reserve, potentially improving embryo quality and increasing IVF success rates. It is particularly beneficial for women who do not respond adequately to a single stimulation phase, providing more opportunities to create viable embryos.

The method has proven effective for women of advanced maternal age or those with low egg quality, as it optimizes the use of the available ovarian reserve. By implementing Double Stimulation, patients may experience a higher chance of pregnancy while reducing the need for multiple procedures and shortening the overall treatment time.
