By Mayo Clinic staffFor most men, the only sign of low sperm count men is the inability to conceive a child (infertility). A couple is considered infertile if they're unable to conceive after one year of regular intercourse. If sperm production is impaired by an underlying hormonal problem, you may have other signs such as decreased facial or body hair or problems with sexual function.
