Conditions affecting sperm production
Up to 15 percent of couples are infertile. This means they aren't able to conceive a child, even though they've had frequent, unprotected sexual intercourse for a year or longer. In over a third of these couples, male infertility plays a role. Male infertility is due to low sperm production, abnormal sperm function or blockages that prevent the delivery of sperm. Illnesses, injuries, chronic health problems, lifestyle choices and other factors can play a role in causing male infertility. Not being able to conceive a child can be stressful and frustrating, but a number of male infertility treatments are available.
What is Male Infertility?

Men can also contribute to infertility in a couple. To conceive a child, a male's sperm must combine with a female's egg. The testicles make and store sperm, which are ejaculated by the penis to deliver sperm to the female reproductive tract during sexual intercourse. The most common issues that lead to infertility in men are problems that affect how the testicles work.
Low sperm count
Back to Health A to Z. A low sperm count, also called oligozoospermia, is where a man has fewer than 15 million sperm per millilitre of semen. Having a low sperm count can make it more difficult to conceive naturally, although successful pregnancies can still occur.
When it comes to infertility, women get a lot of the blame. What causes male fertility decline? And how is it similar—and different—from the fertility decline women experience? This is known as reduced egg quality. Because both egg count and egg quality decline with age, it makes sense that—while there are other causes of female infertility—age is the most influential factor when it comes to female fertility.
