Spermosens AB (publ)
Spermosens, founded in 2018, develops medical devices for male infertility, to individualize and adapt In Vitro Fertilization treatments. The patent-pending technology is based on the discovery of the JUNO protein in egg cells by two independent research groups. Spermosens’ first product, JUNO-Checked, consists of two components: a measuring instrument with associated software, as well as disposable chips. The measuring instrument analyzes the sperm applied to the chip and finds out the binding capacity to the egg cell, which enables an individualized choice of appropriate fertility treatment based on the measured binding capacity.
