There is a link between male infertility and age. Infertility is considered when a man who has a normal sex life and is not using contraception does not get pregnant for more than a year. There are many causes of male infertility, and age is one of them. Fertility in middle-aged and older men declines as they age. This is because age causes degenerative changes in the body’s organs and tissues, which naturally affects a man’s ability to reproduce and puts him at an increased risk of infertility. Age is only one of the many factors that can cause male infertility. Men who suffer from infertility should consult a doctor in a timely manner to clarify the cause of the disease through a comprehensive examination, and then take the appropriate means of intervention and treatment.
