The symptoms of infertility in men can be very vague and can even go unnoticed until a man tries to have a child with a woman.
The symptoms are dependent on the cause of infertility and can include:
- Loss of sexual desire
 - Loss of hair (alopecia) and other changes in the growth of hair
 - A lump, pain or swelling in the testicles
 - Issues with ejaculation and erections
 - Small and firm testicles
