The effect of intratesticular autologous platelet-rich plasma injection on sperm retrieval rates and in vitro fertilization outcomes in couples with non-obstructive azoospermia.

Aim: To assess the efficacy of intratesticular injection of autologous platelet-rich plasma (PRP) in men with non-obstructive azoospermia (NOA) and a history of failed microdissection-testicular sperm extraction (mTESE) procedures.

Methods: A prospective case series of a cohort study was conducted involving couples diagnosed with NOA. Patients with at least one failed mTESE procedure were included.
