Spermatogenic failure-30 (SPGF30) is characterized by male infertility due to nonobstructive azoospermia or cryptozoospermia. The few sperm that have been observed are immotile and have small heads. Testicular histology in azoospermic patients shows incomplete maturation arrest, with a Sertoli cell-only pattern in some areas (Arafat et al., 2017).
