While testosterone is typically seen as a "male" hormone, it's also present (albeit in much smaller amounts) in women. However, between 4-7% of American women produce too much testosterone in their ovaries, which usually leads to a condition called polycystic ovary syndrome.  Too much testosterone in women can lead to infertility due to lack of ovulation, as well as some embarrassing symptoms like acne, a deepening voice and facial hair growth. Reducing testosterone levels in women is often accomplished with medication, although dietary change can make a positive impact also.
