A clinical study presented at the European League Against Rheumatism Congress 2015 in Rome found something remarkable: young women who regularly used pain-relief medicines such as diclofenac, naproxen, and etoricoxib (drugs from the group of nonsteroidal anti-inflammatory drugs often used to treat pain, such as lower back pain, migraines, and even menstrual cramps) seemed to have been seriously undermining their fertility that way.

Although this process seems to be reversible, a woman is not going to ovulate (or will have an impaired ovulation) if she continues to take these drugs continuously.
