Genetic abnormalities represent an important but often overlooked cause of male infertility. Certain inherited conditions can impair sperm production or disrupt reproductive anatomy.
One example is Klinefelter Syndrome, a chromosomal disorder in which males possess an extra X chromosome. This condition frequently results in reduced testosterone production and impaired spermatogenesis.
Another genetic cause involves microdeletions within the Y chromosome. These deletions affect genes responsible for sperm production and may result in extremely low sperm counts or complete absence of sperm.
Advances in genetic testing now allow physicians to detect these abnormalities with greater accuracy. Identifying genetic causes of infertility helps guide treatment decisions and counseling for affected individuals.
Genetic evaluation is particularly recommended for men with erotic severe sperm abnormalities or unexplained infertility.
