Background: Varicocele is an abnormal dilation of the testicular veins in the pampiniform plexus and characterized by retrograde blood flow in the internal spermatic veins due to incompetent or absent valves. It is considered one of the main causes of male factor infertility. Sperm DNA integrity is essential for in vivo and in vitro fertilization, and varicocele causes a progressive decrease in sperm quality . Objective: To study the impact of varicocele on semen quality and sperm DNA integrity. Patients, Materials and Methods: Twenty patients with varicocele and 20 men without varicocele were assigned into two groups in the Out-Patient Clinic of Urology in Al-Kadhimya Teaching Hospital . Semen was collected from both groups and the rate of sperm DNA fragmentation assessed by the "Comet assay" and categorized to 4 classes. Class I (no DNA fragmentation), class II (little DNA fragmentation), class III (meaningful DNA fragmentation), and class IV (high DNA fragmentation) . Results: No statistically significant differences were found between the varicocele and control groups with respect to age. Men with varicocele had significantly higher ejaculate volume, lower sperm concentration, and lower progressive motility, and showed more abnormal morphology than men in the control group. The Varicocele group showed a lower percentage of sperm with little DNA fragmentation (class II) and a higher percentage of sperm with DNA fragmentation (class IV), than the control group. Conclusions: Compared with men without varicocele, men with varicocele had a higher percentage of cells with DNA fragmentation .
The purpose of the study was to determine if age and body mass index in infertile men were associated with stress levels as determined by salivary stress biomarkers (cortisol and alpha-amylase). A cross-sectional study comprising 100 males with an infertility challenge was divided into 25 normozoospermia, 26 oligozoospermia, 21 asthenozoospermia, and 28 oligoasthenoteratozoospermia. Salivary cortisol and alpha-amylase were examined using the ELISA technique . The average age of the patient was 30.85±7.03, and their average BMI was 27.604±5. 7894. The infertile duration mean was 4.7896±3. 85932. The average amylase content in the saliva was 127.3721±40.0952, while the average cortisol content was 72.67±49.09. There are no discernible variations between the comparison mean of BMI and the duration of infertility. In the current investigation, there was no discernible relationship between SAA and age, BMI, or the length of infertility. Saliva cortisol and BMI in the oligoasthenoteratozoospermia group showed a substantial negative correlation (r = 0.483 & p = 0.009), although no significant link was seen with age, BMI, or length of infertility in the other study groups. There was no significant positive or negative correlation found between SAA level and the age and BMI of the four study groups, whereas salivary cortisol showed a substantial negative correlation with BMI in OAT and a non-significant correlation with age.
