N normal phenotype
reproductive system
• elevated rate of sperm teratospermia
• sperm exhibit a loss of the characteristic hook-shaped curvature of the sperm head, showing a blunt, rounded morphology
• acrosomal structure is aberrant
• acrosome is detached from the nuclear membrane
• males exhibit reduced fertility, producing a decreased number of offspring
• intracytoplasmic sperm injection with mutant sperm leads to only sporadic cleavage of oocytes by day 2, and these cleaved embryos arrest at the 2-cell or 4-cell stage indicating fertilization and embryonic arrest
• sperm exhibit impaired ability to fertilize artificial oocyte activated oocytes
• sperm treated with SrCl2 combined with ionomycin significantly rescue the fertilization capability of sperm
