The relationship between anthropometric and metabolic risk factors and testicular function in healthy young men.

OBJECTIVE: This study investigated the relationship of anthropometric and metabolic risk factors with seminal and sex steroidal hormone parameters in a screened population of healthy males. METHODS: The participants were healthy young men without chronic or congenital diseases. The body composition parameters that we investigated were measured weight, height, and waist circumference (WC), as well as bioelectrical impedance analysis. Semen samples were analyzed for semen volume, sperm concentration, sperm motility and morphology, seminal pH, and liquefaction time. Biochemistry analysis, including glucose and lipid metabolism parameters, was conducted on fasting blood samples. Testicular volume was calculated separately for each testis using ultrasonography. RESULTS: Body mass index exhibited an inverse association with total sperm count. WC showed negative correlations with numerous seminal parameters, including sperm concentration, total sperm count, sperm morphology, and follicle-stimulating hormone levels. The basal metabolic rate was associated with seminal pH, liquefaction time, and sperm motility. WC, fat mass percentage, and triglyceride levels exhibited negative correlations with sex hormone binding globulin. The measures of glucose metabolism were associated with a greater number of seminal parameters than the measures of cholesterol metabolism. C-reactive protein levels were inversely associated with sperm concentration and total sperm count. CONCLUSION: Anthropometric and metabolic risk factors were found to predict semen quality and alterations in sex steroidal hormone levels.

Suprapubic bladder aspiration: A novel method in the diagnosis of retrograde ejaculation / Aspiración vesical suprapúbica: Un nuevo método para el diagnóstico de la eyaculación retrógrada

Introduction and objectives: To investigate the role of suprapubic bladder aspiration (SBA) in the diagnosis of retrograde ejaculation (RE) which is diagnosed with the observation of sperm in post-ejaculatory urine (PEU). However, sperm is also observed in PEU after the wash out of the retained ejaculate in the urethra with the expulsion of urine in several subjects. Therefore, detection of sperm in PEU in the diagnosis of RE is problematic and a better method is needed to overcome the ambiguity of positive PEU and to identify which patient experience true RE.Material and methods: A cohort of patients underwent an examination for RE over a two-year period at a single specialist centre. All patients underwent SBA and semen analysis. Sperm was investigated in urine aspirated from the bladder and in PEU.Results: Thirty-two patients (age range 18–62 years) underwent SBA and PEU for investigation of RE. Sperm was detected both in SBA and PEU in 19 patients, while 5 patients revealed sperm only in PEU. The mean number of sperm found in SBA was less than the mean number of sperm observed in PEU in all 19 patients.Conclusion: SBA is a reliable and feasible method in the diagnosis of RE and can distinguish the true RE in which sperm flows backward into the bladder from the retained ejaculate in the urethra. The whole ejaculate does not likely flow retrogradely and RE could be a partial leakage of the ejaculate into the bladder. (AU)

Introducción y objetivos: Investigar el papel de la aspiración vesical suprapúbica (AVS) para el diagnóstico de la eyaculación retrógrada (ER), que es diagnosticada con la observación de esperma en la orina posteyaculatoria (OPE). Sin embargo, el esperma también se observa en la OPE después del lavado del eyaculado retenido en la uretra con la expulsión de la orina en algunos sujetos. Por tanto, la detección de esperma en la OPE es puede ser problemático para el diagnóstico de la ER y es necesario un método mejor para superar la ambigüedad de OPE positiva e identificar qué pacientes experimentan verdadera ER.Material y métodos: Se examinó una cohorte de pacientes para ER durante un periodo de dos años en un único centro. A todos los pacientes se les realizó una AVS y un análisis del semen. Se investigó la presencia de esperma en la orina aspirada de la vejiga y en la OPE.Resultados: Se incluyeron treinta y dos pacientes (rango de edad 18-62 años) a los que se les realizó AVS y análisis de OPE para investigar la ER. Se detectó esperma tanto en la AVS como en la OPE en 19 pacientes, mientras que en 5 pacientes sólo se detectó esperma en la OPE. El número medio de esperma encontrado en la AVS fue inferior al observado en la OPE en los 19 pacientes.Conclusión: La AVS es un método fiable y factible para el diagnóstico de la ER y puede distinguir entre verdadera ER en la que el esperma fluye marcha atrás hacia la vejiga, del eyaculado retenido en la uretra. Es probable que no todo el eyaculado fluya retrógradamente y que la ER pueda ser una fuga parcial del eyaculado hacia la vejiga. (AU)
