For almost a century, Bayer has been working to make a positive difference to women’s health through pioneering research and innovation.

In the 1920s, Bayer—then called Schering AG—made a significant contribution to understanding the molecular structure of sex hormones and launched the world's first oestrogen preparation for menopause management. This firmly set Bayer as a pioneer in women’s healthcare and, in 1961, Bayer became the first company to launch a contraceptive pill in Europe, the combined oral contraceptive Anovlar® (norethisterone acetate/ethinylestradiol).

More recent innovations include the introduction of Kyleena® (19.5 mg intrauterine delivery system levonorgestrel) a low-dose, levonorgestrel-releasing intrauterine delivery system which was launched in Ireland in 2017.
