Effect of ibuprofen on semen quality.

Ibuprofen is a widely used analgesic/antipyretic medication belongs to the nonsteroidal anti-inflammatory class. Even though the influence of ibuprofen on semen quality has been investigated in various occasions, the comprehensive understanding and discussion of its impact on semen quality is still yet to be determined. In this work, we systematically review and reveal the effect of ibuprofen on semen quality, and thus on fertilising capability. To achieve this goal, we searched the main research databases (Scopus and PubMed) from 1 June 1986 through 13 October 2018 for English-language articles and abstracts using the keywords "ibuprofen" versus "semen" and "sperm". In addition, related published articles or abstracts were also discussed if relevant. Altogether, the main stream of research, from both in vitro and in vivo studies, presents an adverse effect of ibuprofen on different sperm parameters such as motility, viability, count and DNA integrity; however, such effect is not yet confirmed in humans. Mechanisms by which ibuprofen affects semen quality may be by reducing testosterone and prostaglandin synthesis, chelating zinc ions and inhibiting nitric oxide synthesis. However, further research studies, mainly clinical, are still of great importance to confirm the effects of ibuprofen on semen quality.
