IVF protocols are roughly divided into long protocols, ultra-long protocols, short protocols, antagonist protocols, microstimulation protocols, and natural cycle protocols, with recent trials of luteal phase ovulation induction protocols. As for which protocol to use, since you have chosen a doctor you trust, you should follow the doctor’s recommended protocol, no matter how it ends. I believe that every responsible doctor will do his/her best to choose the option that is right for you, so what is right for you is the best option. We often come across patients who will compare other patients’ programs and even the outcome , I think this is meaningless, but rather affects your own emotions, and as a result, leads to some neuroendocrine changes, and ultimately affects the outcome of your own pregnancy. If you have had IVF in another hospital, it is important to inform your doctor in detail about your visit so that he or she can help you with the next step in your program and avoid detours and financial as well as physical losses.
