SUMMARY The effects of follicle-stimulating hormone (FSH) and luteinizing hormone (LH) on plasma testosterone levels were examined in hypophysectomized and in intact immature and adult male rats. The animals were injected with saline, LH, FSH, or both gonadotrophins twice daily for 3·5 days and were killed 3 h after the last injection. Plasma testosterone levels were measured by radioimmunoassay. In immature hypophysectomized rats, plasma testosterone levels were not changed by treatment with LH, FSH or LH plus FSH. The weight of the testes and of the seminal vesicles was increased only in animals injected with both LH and FSH. In adult hypophysectomized rats, LH caused the expected increase in plasma testosterone levels, while FSH injected alone had no effect. Plasma testosterone levels in rats treated with 5 μg LH and 20 μg FSH were significantly greater than those in animals given 5 μg LH alone. However, the same dose of FSH did not potentiate the action of 25 μg LH on plasma testosterone levels. In adult hypophysectomized rats the weight of testes was not affected by any of the treatments. The weight of the seminal vesicles was increased by the higher dose of LH and addition of FSH caused no further increase. In intact immature and adult rats plasma testosterone levels and the weight of testes were not changed by any of the treatments. Seminal vesicle weight was increased only in adult rats treated with the higher dose of LH together with FSH. The results demonstrate that FSH potentiates the action of low doses of LH on plasma testosterone levels in adult hypophysectomized rats and suggest that FSH may be involved in the regulation of androgen secretion by the rat testis.

Abstract BackgroundEpilepsy is one of the common neurological brain defects that causes unpredictable, recurrent seizures. It has adverse effects on the reproductive functions.Oxidative stress contributes to the evolution of epilepsy, including reduction of sperm count and motility,increase of abnormal sperm morphology, and low testosterone.Antioxidants are beneficial to spermatogenesis and sperm parameters. Satureja edmondiBriq is known as a powerful antioxidant that can reduce the effects of oxidative stress. The aim of this study was to evaluate the effects of Satureja edmondion reproductive potential in pentylenetetrazol (PTZ)-induced epileptic male rats.MethodsIn this experimental study, 48 Wistar male rats with an average age of 10 weeks and weightof 240- 260g were used. Animals were randomized into normal and kindled groups that were treated with different doses of S.edmondi essential oil. Treatment of animals lasted 4 weeks. In the end, testosterone, follicle-stimulating hormone, luteinizing hormone, and sperm parameters were measured according to the World Health Organization (WHO) standards.ResultsThis study showed that all sperm parameters,including sperm count, sperm viability, and progressive sperm motility were increased and testosterone, follicle-stimulating hormone and luteinizing hormone (FSH,LH) changes in the epileptic and normal groups were changed with an increase in the dose of S.edmondi essential oil. ConclutionsThe changes were significant in some parameters. S.edmondi as a good source of antioxidants can improve sperm parameters and reproductive potential in PTZ-induced epileptic male rats.
