    Background
    The effects of lifestyle and physical factors on male fertility potential are controversial and these disagreements have increased public and research attention.
    Objectives
    This study was planned to evaluate the effects of modifiable lifestyle and physical factors on the semen quality and assisted reproductive outcomes.
    Methods
    This prospective study evaluated lifestyle and physical factors in 306 infertile men under an assisted reproductive program such as body mass index, age, abstinence time, tobacco smoking, varicocele treatment, physical activity, caffeine consumption, and the use of cell phones, as well as sperm chromatin integrity and condensation, semen parameters, and assisted reproductive outcomes between 2016 and 2018. Statistical analysis was performed using SPSS version 20 and CorrelationAttributeEval and Ranker modules of WEKA software were applied to evaluate the effect of each feature/factor of men on the biochemical pregnancy rate.
    Results
    A negative association was seen between the total sperm count and abstinence time (< 3 days, P = 0.02) and caffeine consumption (> 4 cups/d, P = 0.03). A decreased sperm concentration, normal morphology, motility, and chromatin normality were found in the categories of older age (> 35-years-old) and elevated BMI (> 30, P = 0.03). The poor embryo quality (grade D) and increased spontaneous abortion were found in men with high age, BMI, caffeine consumers, and smokers. The effects of smoking, age, and BMI weighed more than the effects of other parameters on biochemical pregnancy.
    Conclusions
    Factors such as aging, elevated BMI, smoking, and high consumption of caffeine via affecting sperm parameters and increasing DNA damage may affect assisted reproductive outcomes (e.g., poor embryo quality and high abortion).

    Background
    Hazardous health effects of the exposure to radiofrequency waves (RFWs) have become of great public concern and impaired memory has been reported following the exposure to electromagnetic radiations.
    Objectives
    As the deleterious effects of the RFW on passive avoidance learning and memory had already been reported, the aim of this study was to evaluate the prophylactic effect of vitamin C on this activity.
    Methods
    20 male Sprague-Dawley rats (230 ± 20 g) were divided randomly into four groups as: control, control-exposed (exposed to 900 MHz RFW), control treatment (without exposure to RFW receiving 250 mg/kg of body weight/day L-ascorbic acid by gavage), and treatment (exposed to 900MHz RFW receiving the abovementioned dose of vitamin C) groups. The exposure was performed for 30 consecutive days (4 h/day). Learning and memory were evaluated in the last day by the shuttle box and expressed as the period of remaining within the light area; this time was called “light time”.
    Results
    The exposure to RFW significantly decreased the duration of light time in the control-exposed group compared to the other three groups (P < 0.05). In the fourth group, vitamin C significantly increased the light time compared to the control-exposed group (P < 0.05). No significant difference was observed between control, control treatment, and treatment groups.
    Conclusions
    Exposure to RFW significantly altered the passive avoidance behavior. Vitamin C probably due to its antioxidant effects has facilitative results on the acquisition and retrieval activities of passive avoidance learning and memory in rats.
