Effects of isoflurane inhalation on the male reproductive system in rats.
The 15-day intact adult male assay was used to evaluate effects of isoflurane on the testes and sexual hormones. Forty adult male Sprague-Dawley rats were divided into five groups exposed to air containing 0, 50, 300, 1800 or 10,800 ppm isoflurane. After the treatments, serum was collected for the hormones assay. ⋯ The serum follicle-stimulating hormone and testosterone concentrations reduced significantly at doses of 1800 and 10,800 ppm. Isoflurane induced impairments of seminiferous tubules and spermatogenesis. The testicular damages caused by isoflurane can be related to the imbalances in the sexual hormones.
