Implication

Genetic knockout experiment reveals that Catsper3 and Catsper4 deficiency causes male infertility in mice, highlighting potential targets for male contraceptives.

Key Points

To determine the biological functions of testis-specific genes Catsper3 and Catsper4 in sperm hyperactivated motility and male fertility.
Generated Catsper3 and Catsper4 targeted knockout mouse models.
Assessed sperm motility, hyperactivation under capacitating conditions, and reproductive fertility in male knockout mice.
Catsper3 and Catsper4 knockout male mice exhibit complete infertility.
Knockout sperm demonstrate a rapid loss of motility and a total absence of hyperactivated motility under capacitating conditions.
