This document describes various ovarian stimulation protocols for infertility treatment, including oral medications, injectable medications, and monitoring techniques. It summarizes protocols for natural cycles, mild stimulation, conventional stimulation, antagonist protocols, and protocols for poor responders. Key points include the use of clomiphene citrate, gonadotropins like hMG and rFSH, protocols with and without downregulation, monitoring with ultrasound and hormones, and tailoring the protocol based on ovarian reserve and previous response. The goal is to recruit multiple follicles for retrieval while avoiding overstimulation and maintaining endometrial receptivity.
