Ibuprofen does not have an adverse impact on semen parameters.

Purpose: A recent study suggested that ibuprofen may alter testicular physiology in a state of compensated hypogonadism, but only evaluated spermatogenic cells in a laboratory ex-vivo model with no significant effect, and found no significant change in follicle stimulating hormone (FSH) in men treated with ibuprofen. The study did not evaluate the impact of ibuprofen use on clinical semen parameters, which has not been assessed to date. The purpose of this study was to evaluate the impact of ibuprofen on semen parameters.

Methods: In a retrospective chart review from October 2012 to February 2018, 64 men had semen analyses revealing leukocytospermia and were treated with a 3-week course of ibuprofen 600 mg every 8 hours (1800 mg per day) and had a repeat semen analyses 3 weeks later.

Results: Of the 64 men diagnosed with leukocytospermia, 51 returned for post-treatment semen analyses. Parameters included semen volume, sperm concentration, motility, TMC, and forward progression. Morphology was excluded as it could not be standardized between assessments with strict Kruger criteria versus WHO fourth edition criteria depending on the lab in which it was performed. The mean age of these men was 35 (SD 4.6). There was no difference in mean abstinence intervals prior to semen analyses for the pre-treatment and post-treatment data. There was no significant difference in pre-treatment and post-treatment semen volumes, sperm concentrations, motility, TMC, or forward progression.

Conclusions: Among men with leukocytospermia, the treatment with a 3-week course of ibuprofen at 1800 mg per day did not demonstrate a significant adverse impact on semen volume, sperm concentration, motility, TMC, or forward progressive motility when compared to pre-treatment semen analyses parameters.
