Can semen analysis be utilized as a screening tool for overall health in young men?

Traditionally, semen analysis has been viewed solely as a tool for assessing male fertility. However, emerging research suggests that abnormal semen parameters may serve as indicators of broader health issues beyond reproductive function. Studies have revealed significant associations between abnormal semen parameters and an increased risk of chronic diseases such as prostate cancer, diabetes, ischemic heart disease, and metabolic disorders. These findings challenge the conventional understanding and position semen analysis as a potential screening tool for overall male health. The correlation between abnormal semen parameters and conditions like erectile dysfunction further underscores the multifaceted implications of semen quality. This suggests that abnormal semen parameters may be a risk factor for poorer overall health and a higher likelihood of developing comorbidities over time. Given these compelling associations, there is a growing call to integrate semen analysis into routine health assessments for young men, particularly in conjunction with established general health screenings. This proactive approach aligns with a preventative healthcare paradigm, facilitating early detection of underlying health concerns and timely interventions. However, overcoming cultural, logistical, and cost-related barriers is crucial for the successful implementation of this shift in reproductive health.

The Utilization of Fine-Needle Vasography to Localize Obstruction of the Male Reproductive Tract.

OBJECTIVE: To report our experience using fine-needle vasography (FNV) to identify a site of obstruction and determine candidacy for reconstructive procedures in patients presenting with suspected obstructive azoospermia (OA) or cryptozoospermia. METHODS: We report a multi-institutional case series of patients with suspected complete or partial OA. Patients that were included had azoospermia or cryptozoospermia, presence of palpable vasa, testicles ≥12 mL, and FSH <7.6 IU/L. All patients underwent testicular biopsy prior to or at the time of FNV to confirm spermatogenesis. FNV was performed using a 25-gauge angiocatheter, with radio-opaque dye visualized under fluoroscopy. Descriptive statistics are reported as median and interquartile range (IQR). RESULTS: A total of 16 patients underwent vasography from 2014 to 2022 with 3 surgeons. Twelve patients presented with azoospermia, and 4 with cryptozoospermia. A total of 7 (44%) men were found to have distal obstruction on FNV. Of the 8 men with prior inguinal hernia repairs, 2 were confirmed to have an obstruction at the level of the inguinal canal. Of the 6 patients with a history of genitourinary infection, 4 had an obstruction at the level of the epididymis (with normal FNV), while 2 had atresia of the vas deferens in the pelvis. CONCLUSION: FNV is an effective, minimally invasive way to identify the site of complete or partial obstruction in patients presenting with suspected OA/cryptozoospermia. It additionally permits identification of men who are candidates for epididymovasostomy reconstruction and helps to differentiate between ejaculatory duct obstruction (EDO) and other causes of blockage.
