A stimulation protocol is the overall plan of fertility medicines and monitoring used to control ovarian stimulation during an IVF cycle. Commonly described protocol types include the long protocol (which uses a longer course of medicine to suppress the pituitary gland before stimulation begins), the short protocol, and the flare protocol (which uses an early hormone effect to help kick-start follicle development). The choice of protocol is individualised based on factors such as age, ovarian reserve, prior response to treatment, and the presence of conditions such as PCOS or endometriosis. No single protocol suits everyone, and switching protocols between cycles is a recognised part of individualising care rather than a sign of prior treatment failure. This entry does not describe medicine names, doses or schedules, which are decided by the treating specialist.
