Spermatogenic failure-87 (SPGF87) is characterized by male infertility, with total fertilization failure due to inability of mutant sperm to penetrate the zona pellucida. Infertility can be rescued by intracytoplasmic sperm injection without assisted oocyte activation (Hua et al., 2023).
For a general phenotypic description and discussion of genetic heterogeneity of spermatogenic failure, see SPGF1 (258150). [from
