What is the primary purpose of testicular self-examination?

The primary purpose of testicular self-examination is to serve as a means of early identification of testicular cancer. This practice allows individuals to become familiar with the normal shape and feel of their testicles, enabling them to notice any unusual changes, lumps, or swelling that could indicate potential health issues, including cancer. Early detection is crucial for effective treatment and positive outcomes, as testicular cancer, when caught early, has a high cure rate.

The other options, while related to male reproductive health, do not align with the specific purpose of testicular self-examination. For instance, increasing fertility or assessing testicle size are not direct objectives of this self-examination technique, nor does it serve to measure hormone levels. The primary focus remains firmly on identifying any abnormalities that might suggest cancer, which underscores the importance of regular self-exams for men.
