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. Other problems are hormone imbalances or blockages or absence of some of the ducts in the male reproductive organs.
When a man does not produce sperm, it is called azoospermia pronounced ay-zoh-uh-SPUR-mee-uh. A hormone imbalance or a blockage of sperm movement can cause azoospermia. In some cases of infertility, a man produces less sperm than normal. The most common cause of oligospermia is varicocele pronounced VAR-ih-koh-seelan enlarged vein in the testicle.
Many different issues can affect the formation of sperm in the testicles. These conditions can lead to sperm that is abnormally shaped or malformed or to low amounts of sperm.
Some of the more common issues include: Remember that lifestyle, environmentaland age-related factors can also play a role in male infertility.
Even if the male’s body produces enough viable sperm, sometimes factors and conditions that affect how or whether the sperm moves can also contribute to infertility. Sperm may move too slowly or not at all and thus die before they can reach the egg.
Sometimes the seminal fluid, which contains the sperm, is too thick for the sperm to move around properly. Many men with cystic fibrosis lack the tubes that carry the sperm out of the testicles, making them infertile but not sterile, because they produce sperm.
Some men have problems getting an erection, called erectile dysfunction, which makes having sex difficult. A condition called retrograde ejaculation can also cause infertility.
