He added that his wife had taken the initiative of having a thorough gynecological evaluation in an attempt to find out what was causing the problem. Her test findings revealed no physical conditions that could be linked to infertility. Upon palpating the patient’s testes, the doctor found nothing un- usual. When he examined the scrotal sac above the testes, however, the doctor appeared per- plexed. He informed his patient that two tubular structures, one for each testis, appeared to be absent, and that they probably had been missing since birth. During a follow-up visit, the doc- tor told the patient that examination of his ejaculate revealed azoospermia (no viable sperm). Explain how the result of the semenalysis relates to the patient’s physical exam findings.
