Abstract
To investigate some possible effects of low doses of nonsteroidal anti-inflammatory drugs upon functional activity of mouse sperm, the authors injected lysine acetyl salicylate (im 14.3mg/kg day-1), ibuprofen (ip 5.6 mg/kg day-1), or piroxicam (ip 0.28 mg/kg day-1) to pregnant females (the male cohort was sacrificed at adulthood) (A) or to adult males during 35 (B) or 60 (C) days. Parameters measured were motility, viability, acrosomal integrity, responses to hypoosmotic shock, in vitro fertilization index, and testosterone plasma levels. Salicylate evoked a slight reduction in the percentage of swollen gametes in A, and ibuprofen diminished testosterone plasma levels in B. The other parameters remained unchanged in all groups. Results are well supported by the low doses assayed, which are equivalent to the content of one tablet commercially available for each compound.
