About 15 percent of couples are infertile, reports MayoClinic.com. In 20 percent of these cases, the infertility problems come solely from the male and, in an additional 30 to 40 percent of cases, infertility is a combination of male and female problems. If you are having problems conceiving, you want to be aware of male infertility symptoms.
Inability to Conceive
The strongest sign of infertility is the inability to conceive a child after a year of frequent, unprotected sex. This does not necessarily show that the infertility issues are with the man, but if the woman has conceived in the past, it’s a stronger sign that it’s male infertility.
Infertility can also come from problems with sexual function. To conceive, the sperm must reach the egg. This can happen if the man has problems getting or maintaining an erection, or if there is some type of blockage preventing ejaculation.
If a man has a non-descended testicle, it can cause fertility issues. Additionally, if he finds a bump–especially a painful one–somewhere in his testicles, there may be a problem.
Hormonal imbalances can also affect the production of sperm. Physically, you may see the man taking on more female physical traits, such as losing facial hair or growing “man boobs” (that aren’t a result of weight gain).
Lifestyle choices can also affect a man’s fertility. If the man is a regular drinker, smoker or drug user, this negatively affects sperm quality. When coupled with the inability to conceive, these lifestyle choices could point to a problem with male fertility.
High Body Fat
Men who are overweight or obese can also have trouble conceiving. If there doesn’t seem to be a problem with the woman’s fertility and the man is overweight, losing weight could help conception.
