Should Scrotal Color Doppler Ultrasound Be Routinely Indicated in Fertility Evaluation of Non-Azoospermic Men?

Objective: Scrotal ultrasound is not a routine investigation in the clinical approach to male infertility analysis. This study aims to identify the role of testicular Doppler ultrasound in male infertility assessment and its relation to semen parameters in non-azoospermic men. Methods: Cross-sectional descriptive analysis of 558 men from infertile couples were examined at the Hue Center for Reproductive Endocrinology and Infertility, Hue University Hospital from June 2016 to May 2018. Some cohort characteristics, semen analysis and testicular Doppler ultrasound were analyzed. Men with acute systemic diseases, acute urinary tract infection, hepatic dysfunction, malignant diseases, retrograde ejaculation, cryptorchidism or azoospermia were excluded. Results: The mean volumes of the right and left testicles were 8.87 and 8.77 ml, respectively. The total volume of the 2 sides was 17.63 ± 4.34 ml (95% confidence interval 17.27-18.00 ml). The mean right resistive index (RI) was 0.61 ± 0.23, and the mean left RI was 0.59 ± 0.01. The rate of normal semen quality was 23.2% in group with varicocele and 30.6% in group with non-varicocele. The ultrasound results from the normal semen group were much different from those of the abnormal semen group regarding testicular volume: mean right testis volume: 9.67 ± 1.88 vs. 8.75 ± 2.34 ml, p = 0.0096; mean left testis volume: 9.54 ± 1.78 vs. 8.51 ± 2.44 ml, p = 0.0047; mean total volume of 2 sides: 19.21 ± 3.60 vs. 17.26 ± 4.59 ml, p = 0.005 (varicocele group); mean right testis volume: 9.21 ± 2.21 vs. 8.63 ± 2.21 ml, p = 0.029 (non-varicocele group). The other indexes of color Doppler ultrasound (peak systolic velocity, end diastolic velocity, RI) were not found to correlate with semen quality. Conclusions: Testicular volume which has a close relation to the semen parameters could be used as a clinical prediction factor for the quality of semen.

Objective: To assess the effect of injecting magnesium sulfate on Doppler parameters of fetal umbilical and middle cerebral arteries (MCA) in women with severe preeclampsia. Materials and Methods: A total of 21 patients with severe preeclampsia admitted to Imam Reza Hospital, Kermanshah (Iran), were evaluated. Before and after administration of magnesium sulfate, Doppler ultrasound scan was carried out to measure fetal middle cerebral artery and umbilical artery blood flow. Paired t-test was used for statistical analysis. Results: After injection of magnesium sulfate, the mean resistivity index (RI)-umbilical, and pulsatility index (PI)-cerebral showed a statistically significant reduction (P < 0.001). The cerebroumbilical C/U ratio increased after the intervention (P < 0.001). The PI-umbilical (P = 0.1) and pre- and post-RI-cerebral (P = 0.96) did not have statistically significant changes. Conclusions: Infusion of magnesium sulfate significantly decreases the flow in the fetus RI-umbilical and PI-MCA, and it increases C/U ratio indices in color Doppler ultrasound.

Abstract Background The effect of ambient pollutants on the male reproductive system is controversial. This retrospective study investigated the effect of environmental pollutants on male reproductive health. Methods Male patients with primary infertility (n = 282) were identified from a single center between January 2016 and December 2017. Patients were physically examined for the presence of varicocele and for the volume of both testicles. Semen quality was measured in terms of the total sperm count, sperm concentration, and the percentage of sperm cells with motility and normal morphology. Data were acquired on the concentration of ambient pollutants, namely particulate matters of diameter < 2.5 μm, sulfur dioxide (SO2), nitrogen oxides (NOx), and ozone (O3), measured on daily and hourly basis, from the Environmental Protection Administration Executive Yuan, Taiwan. Individual exposure to pollutants was estimated based on the reported residential address of each participant. Statistical analysis indicated the effect of each pollutant on the testicular volume, sex hormone profile, and semen parameters. Results The mean ± standard deviation of age was 36.7 ± 7.3 years. The average sperm count and concentration were 41.9 million/mL and 34.1 million/mL, respectively. The mean levels of serum testosterone, follicle-stimulating hormone, and luteinizing hormone were 3.57 ± 1.68 ng/mL, 7.59 ± 6.3 IU/L, and 4.68 ± 3.49 IU/L, respectively. According to the multivariate linear regression model, NOx exposure was a risk factor for decreased sperm concentration and motility (p = 0.043 and 0.032). Furthermore, SO2 exposure was negatively associated and testicular volume (p < 0.01). Conclusions NO2 and SO2 exposure were negatively associated with the seminal parameter and decreased testicular volume, respectively, in a population of men with infertility. However, additional prospective studies are needed to ascertain the cause–effect relation of current results.

Aim: The present study evaluated the effect of differences in the peak systolic velocity (PSV) and resistive index (RI) in the testicular artery (TA), capsular artery (CA), and intratesticular artery (ITA) after microscopic subinguinal varicocelectomy (MSV) on postoperative pain and semen parameters. Patients and Methods: Scrotal color Doppler ultrasound (CDUS) measurements were made in 33 patients (age 18-31 years) prior to MSV and 3 and 6 months after MSV. Pain was recorded using a visual analog scale and sperm concentration was determined to analyze the predictive value of the CDUS parameters regarding surgical outcome. Results: A significant decrease in pain scores was observed in most patients at both follow-ups. The first postoperative CDUS revealed a significant increase in the TA-PSV (p<0.001) and a decrease in the TA-RI (p=0.002) and CARI (p=0.006). The second postoperative CDUS also revealed a significant increase in the TA-PSV and a decrease in the TA-RI, and the PSV in the ITA and CA and RI in the ITA and CA were significantly different from the values obtained pre-operatively and at the first follow-up. A negative correlation was found between the pain level and TA-PSV (r=-0.433, p=0.012), whereas sperm concentration positively correlated with both the TA-PSV and CA-PSV (r=0.534, p=0.001 and r=0.455, p=0.008, respectively).Conclusions: The PSV and RI are useful parameters for detecting changes in testicular microhemodynamics after MSV. In addition, the TA-PSV and CA-PSV can be used to predict improvements in pain and sperm concentration.

Introduction: Body mass index BMI is a risk factor that influences semen quality and reduces male fertility. The aim of this study was to determine the impact of body mass index (BMI) on semen parameters in infertile men. Subject and method: A total of 446 infertile men, the study population was divided into four groups depending on their BMI , underweight (<18.5 kg/), normal weight (18.5-24.99 kg/m2 ), overweight 25-29.99 kg/m2), and obese >30.0 kg/.semen parameters (PH, volume, concentration ,total semen count ,vitality, morphology and motility ) were compared across the four BMI groups. Results: The mean of age was 41.91±6.39, the mean infertility duration was 4.92±3.28, 351(78.7٪) had primary infertility and 95(21.3٪) had secondary infertility. The mean BMI was 29.38± 4.85 and the most of patients 45.2٪ were obese. Conclusion: This study has found evidence of an association between BMI and semen parameters (Sperm concentration, Total sperm count, motility, and vitality) and no correlation between Semen volume, morphology and BMI.
