title: Effect of diclofenac sodium (Voltaren) and prostaglandin E2 on spermatogenesis in mature dogs.
abstract: The effect of the prostaglandin-synthesis inhibitor, diclofenac sodium (Voltaren), and of prostaglandin E2 (PGE2) on spermatogenesis in mature dogs has been studied. Diclofenac sodium at 2.0 mg/kg was given subcutaneously once a day for 42 days. The testes were biopsied every 7 days, and spermatogenesis was quantified showing a marked and statistically significant increase (p less than 0.001). Administration of PGE2 in doses of 2.0 mg/kg subcutaneously, once a day for 15 days, produced a marked and statistically significant decrease in spermatogenesis (p less than 0.001), and an increase in the numbers of exfoliated immature germ cells in the seminiferous tubule lumens.
