Predictive factors for successful testicular biopsy
Introduction: Infertility, the inability to conceive, constitutes a major problem in modern societies. It affects 10 to 15 percent of couples in the United States. Evaluation of infertile men is usually complex and often demands a testicular biopsy. Materials and methods: We reviewed all azoospermic men submitted to testicular biopsy, in our center, during infertility investigation between January 2015 and December 2021. Results: A total of 117 patients with a mean age of 36.5 was considered. Biopsy was positive, as defined by the presence of viable spermatozoids by microscopy, in 48.7% of patients (n = 57). Patients were divided in two separate groups based on positive (PB) or negative biopsy (NB) and compared. PB-group had normal serum total testosterone levels and higher than NB-group (3.7 ng/mL vs. 2.85 ng/mL, p = 0.021), and normal serum FSH levels and lower than NB-group (6.0 mIU/mL vs. 16.0 mIU/mL, p < 0.001). The groups were similar concerning serum LH levels (3.9 mIU/mL vs. 6.3 mIU/mL, p = 0.343. Conclusions: Predicting outcomes of testicular biopsy is a difficult task. Our study found that men with normal testicular volume, normal levels of testosterone and FSH and those with type 1 diabetes mellitus had a higher probability of positive testicular biopsy.
