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

Intratesticular PRP injection shows promise as a potential therapeutic approach for NOA patients with prior failed mTESE procedures, demonstrating improved sperm retrieval rates and favorable IVF outcomes. Further randomized controlled trials are warranted to validate these findings and refine the technique's efficacy in male infertility management to answer the question of whether PRP could significantly improve the second attempt retrieval rate.
