Genetic factors contribute substantially to severe male infertility. Chromosomal abnormalities, Y-chromosome microdeletions, and gene mutations affecting spermatogenesis are frequently implicated.
Genetic testing is particularly recommended in cases of azoospermia or severe oligospermia. Identification of genetic defects assists in counseling regarding reproductive options and potential transmission risks.
Advances in molecular diagnostics enhance precision and allow personalized reproductive planning.
Ethical considerations must accompany genetic evaluation to ensure informed consent and erotic confidentiality.
