What may indicate the presence of testicular factors during a male infertility examination?

Varicocele is a condition characterized by the enlargement of veins within the scrotum, which can negatively affect testicular function and is a well-established factor in male infertility. It can lead to reduced sperm production and lower sperm quality due to increased temperature in the scrotum and impaired testicular blood flow. Recognizing the presence of a varicocele during a male infertility examination can prompt further evaluation and potential treatment options, as addressing this condition may improve fertility outcomes.

In contrast, while elevated BMI may impact overall health and potentially contribute to fertility issues through hormonal changes, it does not specifically indicate testicular factors. Frequent urination is more commonly associated with urinary tract or prostate issues rather than direct testicular problems. Similarly, a chronic cough does not relate to testicular function and is more likely associated with respiratory conditions. Thus, the identification of a varicocele stands out as a direct indicator of testicular factors affecting male infertility.
