Much research remains to be performed on this topic as many cases still receive an unknown causes.
The main sign to watch out for is the inability to conceive a child. There may be no other obvious signs or symptoms. In some cases, however, underlying problems such as inherited disorder, a hormonal imbalance, dilated veins around the testicle or a condition that blocks the passage of sperm could be signs and symptoms.
Although most men do not notice symptoms other than the inability to conceive a child, signs and symptoms are always there and these include:
- Problems with sexual performance — for example, difficulty with ejaculation or small volumes of fluid ejaculated, reduced sexual desire, or difficulty maintaining an erection (erectile dysfunction)
- Pain, swelling or a lump in the testicle area.
- Recurrent respiratory infections.
- Inability to smell.
- Abnormal breast growth.
- Decreased facial or body hair or other signs of a chromosomal or hormonal abnormality.
- A lower than normal sperm count.
How common is male infertility, and what are its causes?
Infertility is defined clinically in women and men who cannot achieve pregnancy after 1 year of having intercourse without using birth control, and in women who have two or more failed pregnancies. Studies suggest that after 1 year of having unprotected sex, 15% of couples are unable to conceive, and after 2 years, 10% of couples still have not had a successful pregnancy. In couples younger than age 30 who are generally healthy, 20% to 37% are able to conceive in the first 3 months.
Many different medical conditions and other factors can contribute to fertility problems, and an individual case may have a single cause, several causes, or—in some cases—no identifiable cause. Overall, one-third of infertility cases are caused by male reproductive issues, one-third by female reproductive issues, and one-third by both male and female reproductive issues or by unknown factors.
To conceive a child, a man’s sperm must combine with a woman’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 in the male reproductive organs. In about 50% of cases, the cause of male infertility cannot be determined.
