Abstract: | The effects of the acute immobilization stress on follicle-stimulating hormone (FSH), luteinizing hormone (LH), estradiol, and testosterone levels in rats were evaluated. The male and female rats were grouped in control and stress groups (7 animals in each group). Vaginal smears were taken daily from female rats and the rats in the proestrus were involved in the experiments. After a 1-h immobilization stress, blood samples from the heart were taken and the serum FSH, LH, estradiol and testosterone levels were measured by radioimmunoassay (RIA). The results were statistically analyzed using the Mann–Whitney U-test. A statistically significant increase of the levels of FSH and estradiol, but not of LH, was found in the female rats after the stress. A statistically significant increase of the FSH concentration was also revealed in the male rats, but there were no significant changes of the LH and testosterone levels. The scientific and applied (medical) aspects of the data obtained are discussed. |
