Retinoic acid receptors (RARs) receive signals essential to cell growth and fertility through retinoic acid, a type of vitamin A. By blocking a type of RAR called RAR-α (which only affects fertility, not cell growth), scientists were able to create a male birth control pill that’s 99% effective. The new pill has no adverse side effects, unlike pills targeting testosterone, which often cause depression and heart disease. Although the pill has only been tested by mice, scientists hope to see promising results when human clinical trials start. Read full article here
