Ovarian stimulation is a crucial phase of IVF treatment. Its objective is to achieve the development of multiple ovarian follicles.
There are different protocols, but in any case, ovarian stimulation must be personalized for each patient.
On the one hand, there is the short ovarian stimulation protocol where the patient will begin to administer the medication once her period has arrived. On the other hand, in the long protocol, the patient will administer a higher dose of hormonal medication since it will begin the days prior to the period.
Another difference between these two forms of ovarian stimulation lies in the type of drugs. In the case of long protocols, GnRh antagonists are usually used, while in short protocols GnRh agonists are used.
