Spermatogenic failure-25 (SPGF25) is characterized by small testes and infertility, with severe oligozoospermia or azoospermia due to maturation arrest at the primary spermatocyte stage (Okutman et al., 2015).
For a general phenotypic description and a discussion of genetic heterogeneity of spermatogenic failure, see SPGF1 (258150). [from
