Surgical Sperm Retrieval Techniques for Assisted Reproductive Technology [PDF]

open access: yesDüzce Tıp Fakültesi Dergisi, 2022
Intracytoplasmic sperm injection provides in vitro fertilization for many infertility conditions. It is also an important treatment option for fertilization in azoospermic men. Sperm production in azoospermic male testicles is possible. In these patients,
