Hormone-Free vs Follicle-Stimulating Hormone-Primed Infertility Treatment of Women With Polycystic Ovary Syndrome Using Biphasic In Vitro Maturation: A Randomized Controlled Trial

(Abstracted from Fertil Steril 2025;123(2):253–261 Controlled ovarian stimulation (COS) is not an optimal fertility treatment for all candidates, and an alternative protocol is in vitro maturation (IVM), although its use is relatively uncommon. Although IVM is safe and effective, it has been shown to be less efficient than traditional in vitro fertilization (IVF) protocols with COS when assessed according to live birth rate.
