Deleterious genetic changes in AGTPBP1 result in teratozoospermia with sperm head and flagella defects

Journal of Cellular and Molecular Medicine, 2023
Approximately 10%–15% of couples worldwide are infertile, and male factors account for approximately half of these cases. Teratozoospermia is a major cause of male infertility.
