History

2019: Frameshift variant of ADCY10, which encodes for sAC, found to be associated with reduced sperm motility. 
2021-2022: Development of prototypes of increasingly potent sAC inhibitors with drug-like properties suitable for use in vivo studies.
2023: Study shows a single dose of a safe, acutely-acting sAC inhibitor with long residence time renders male mice temporarily infertile.

The primary development team has received targeted NIH funding for development of an on-demand nonhormonal male contraceptive using an ADCY10 inhibitor each year from 2023-2025.
