If we speak about the IVF cycle, during stimulation, we monitor progesterone levels and estradiol levels. We need to decide if we do transfer in the same cycle or if we need to do transfer in the next menstrual cycle. When we do the transfer, in the next menstrual cycle, sometimes we prescribe progesterone, if it’s necessary, it all depends on each patient’s history, and we start it during the preparation of the endometrium or after embryo transfer. If we think that you can have a low progesterone level after embryo transfer. When it comes to patients from abroad before the program, during the program, we always speak with our patients, either by mail, messenger, WhatsApp, and we give them our recommendation or prescription during the whole program and during pregnancy.
