In Duroc pigs, Zhang et al. (2023a, b, c) found significant candidate genes related to sperm motility, namely, STRA8, ZSWIM7, TEKT3, UBB, and CATSPER. The TEKT3 is required in mice for proper sperm motility, whereas the mutation in the UBB gene results in male and female infertility in mice. Here, UBB is linked to female infertility.
