The U.S. Environmental Protection Agency (EPA) is offering a licensing opportunity for the development of a diagnostic kit designed to detect male infertility through the identification of the Sperm Membrane Protein 22 (SP22). This initiative aims to address the current ambiguity in male fertility indicators, as existing methods primarily rely on sperm motility and count, which can lead to inconsistent classifications of infertility among men. The patented technology, developed by inventor Gary R. Klinefelter and protected under U.S. Patent 8,497,135, has shown a strong correlation between SP22 and male fertility, with potential applications in human fertility testing, research, and comparative biology studies. Interested parties are encouraged to submit a license application form to the EPA’s Federal Technology Transfer Act team and can find more information on the licensing process at https://www.epa.gov/ftta.
