The primary indicator of male infertility is the inability to conceive a child after one to two years of regular, unprotected sexual intercourse. While infertility itself generally does not show distinct symptoms, additional signs may emerge depending on underlying causes. Some of these symptoms (such as pain, swelling, or a lump in the testicles; abnormal penile discharge) can be directly linked to infertility and serve as warning signs, while others might not be immediately noticed by patients. The conditions and potential symptoms that may indicate male infertility include:
* Inability to conceive a child after one to two years of regular, unprotected sexual intercourse.
* Pain or discomfort in the testicles.
* Swelling or a lump in the testicles.
* Abnormal discharge from the penis.
