Spermatogenic failure-48 (SPGF48) is characterized by male infertility due to a variable spectrum of severely impaired spermatogenesis, primarily at meiosis and resulting in azoospermia. However, sparse postmeiotic germ cell development and retrieval of sperm in some cases has been reported (Wyrwoll et al., 2020).
