YourChoice Therapeutics is revolutionizing the contraceptive market by developing novel non-hormonal, reversible and on-demand contraceptives that can ultimately be used by both women and men. The technology is based on the “molecular condom” concept: the active compound inhibits vigorous sperm motility and prevents sperm from fertilizing the egg. YCTx has identified and developed the plant compound lupeol to prevent a motility pattern of human sperm cells needed to reach and fertilize an egg. Lupeol is effective in small concentrations (10 μM) and not cytotoxic.
