Molecule regulating sperm motility discovered

About 120 million unintended pregnancies occurred each year between 2015 and 2019 worldwide. While there are oral contraceptives for women, the development of oral contraceptives for men has not been successful. Now, a team from Osaka University has used protein sequence data analysis and genome editing technology to find that SPATA33 plays an important role in sperm motility regulation, which will help develop male contraceptives.
