Diagnosis of Sperm Disorders
Semen analysis Sometimes genetic testing (See alsoDiagnostic evaluation of the infertile male: A committee opinion, from the Practice Committee of the American Society for Reproductive Medicine.) When couples are infertile, the man should always be evaluated for sperm disorders. History and physical examination focus on potential causes (eg, genitourinary disorders). Volume of each testis should be determined; normal is 20 to 25 mL. Semen analysis should be done.
