“…In the study of Janson et al (11) that was conducted on students, it was demonstrated that a decrease in serum LH levels was observed with exam stress. Almeida et al (16) found that the stress resulting from immobilization for 6 h in a day decreased serum LH levels by 29% and testosterone levels by 37% in Wistar rats during 60 days.…”

Objective: Invasive surgical interventions creating acute stress may give rise to immunological and hormonal disturbances in patients undergoing surgery. Previous studies reported elevations in serum prostate-specific antigen (PSA) level following coronary bypass and myocardial infarction. The current study aims to investigate the effect of surgical stress on serum PSA level.Methods: Thirty-three patients who underwent open renal stone surgery, without any known infectious prostatic disorder or prostate cancer that may elevate serum PSA level, were included in the study. In all patients, serum levels of total and free PSA (tPSA and fPSA), follicle-stimulating hormone (FSH), luteinizing hormone (LH), total and free testosterone, C-reactive protein (CRP), fibrinogen, albumin, and ferritin and erythrocyte sedimentation rate (ESR) were measured both at baseline and post-operative day 3. Wilcoxon signed-rank test was used for the statistical analysis.Results: The mean age of patients was 53.9±8 (40-66). The mean baseline and post-operative levels of the measured serum parameters are given in Table 1. All of them differed significantly between baseline and post-operative day 3, except for LH, tPSA, and fPSA. CRP, fibrinogen, ferritin, and ESR are known as acute phase reactants of the post-operative endocrine response. However, serum total and free testosterone levels, albumin, and FSH decreased on the contrary acute phase reactants in the present study.Conclusion: According to our results, serum PSA level was not affected by acute surgical stress.

“…To increase the human life quality and manage the problems, stress, and daily life troubles, the things which affect our life should be developed by new statistical observations. Exam stress is one of the biggest problems for the students that they meet every year a few times [12,13]. The best solution to solve the problems is to observe the problems, collect data and find the statistical meaning of them.…”

Stress is a part of human life, especially for urban citizens. Stress is inseparable characteristics of student life, especially exam days. Stress management is one of the first steps which can affect students success during the exams, especially in universities. Blood pressure is the first stress observation symptom to understand its level. Therefore, to understand the stress impact of university students during the exam weeks, a conditional experiment has been designed. 200 students were selected from Bosnian and Turkish female and male. The students` blood systolic, diastolic and heart rate were measured to detect the differences between non-exams days and exam days. The blood pressure measurement has been done 3 times in specific times, non-exam days, midterm and final days. Since non-exam days were taken as stress off days, they were supposed that these days were control data to compare with exam days to see the differences. As a result of the measurements, Bosnian females showed the highest increasing, systolic 13.2%, diastolic 9.3% and heart rate 8.5% during the midterm exam days. The group has been followed by Bosnian males, systolic 6.9%, diastolic 6.1% and heart rate 6.63 increased during the midterm days. Although Turkish students blood pressure and heart rate increased, the values were less than Bosnian students. Moreover, high correlation significance results belonged to Bosnian females and males, 0.722 and 0.698 respectively. Finally, it was concluded that if students have scholarship they have more blood pressure during the exams. While 95% of Bosnian females and 90% of Bosnian males have some scholarship, no Turkish students have scholarship demonstrated the differences between Bosnian and Turkish students blood measurements.

ABSTRACT. The effects of acute restraint stress on sperm motility and reproductive endocrinology were investigated in adult rats. Sperm motility was determined by computer-assisted sperm analysis. Acute restraint stress reduced sperm motility starting after 30 min, and the sperm motility parameters, percentage of motile spermatozoa (%), straight-line velocity, curvilinear velocity, deviation of the sperm head from the mean trajectory and the maximum amplitude of lateral head displacement decreased. It also induced a significant elevation in plasma adrenocorticotropic hormone, prolactin, corticosterone and progesterone and decreased follicle-stimulating hormone, luteinizing hormone, testosterone and immunoreactive (ir-) inhibin. These results clearly demonstrated that the acute restraint stress rapidly suppressed sperm motility and increased the activity of the hypothalamus-pituitary-adrenal axis, whereas it disturbed hypothalamus-pituitary-gonadal axis activity.KEY WORDS: ACTH, corticosterone, LH, restraint stress, sperm motility.J. Vet. Med. Sci. 72(11): 1501-1506, 2010 Sperm motility is an important prerequisite determining the quality and fertilizing ability of semen. Several studies have demonstrated that there is a relationship between psychological stress and sperm concentration, motility and morphometry [9,14,28]. In humans, psychological stress patients had decreased sperm count and motility [4]. Stress due to examination tests disturbed luteinizing hormone (LH) and testosterone concentrations [17].Restraint stress has been used as a procedure to study the effects of stress on reproduction outcome in rodents. Several studies have reported reduced testis weight and viability or percentage of progressive epididymal spermatozoa and increased adrenal weight due to stress in rats [24,34]. In rats, the activation of the hypothalamus-pituitary-adrenal axis by stress depends mainly on the characteristics of the stressor, and the response of this axis to stress also depends on the time of day in which the stressor is applied [29]; immobilization stress resulted in decreases in testicular weights along with viability and progressive epididymal spermatozoa [24].To extend these observations and knowledge, adult male rats were used as an animal model to investigate whether and how acute restraint stress affects sperm motility and reproductive endocrinology in this study. Adult WistarImamichi male rats, weighing between 340 and 430 g and aged 3 months, from Imamichi Institute for Animal Reproduction, Ibaraki, Japan, were used. The rats were housed in a room with controlled illumination (14 L:10 D) and temperature (22°C-25°C) and were given free access to commercial pellets (CE-2, Japan Clea Co., Tokyo, Japan) and tap water ad libitum. All procedures were carried out in accordance with the Guide for the Care and Use of Laboratory Animals prepared by Tokyo University of Agriculture and Technology.Adult male rats were stressed by immobilization in a small plastic bag (DecapiCone, Braintree Scientific Inc., Braintree, MA,...
