Testicular injury is a recognized cause of male infertility that can negatively impact both the quantity and quality of sperm production.1

While the specific physiological mechanisms can vary, physical trauma to the testicles may disrupt the delicate environment required for healthy spermatogenesis. Beyond direct injury, other factors such as anatomic abnormalities or the presence of a varicocele—a varicose vein around the testicle—can similarly impair sperm health and contribute to infertility.1

It is important to note that male infertility is a complex medical condition, and reduced sperm function is sometimes viewed by researchers as a potential risk marker for other health issues later in life, such as prostate cancer. If you are concerned about reproductive health, consulting a medical professional is the most reliable way to assess your specific situation.1
