from Section 3 - Clinical Evaluation and Treatment of Male Infertility
Published online by Cambridge University Press: 06 December 2023
The office evaluation of the infertile male involves a comprehensive history and physical structured to uncover all potential causes including congenital, medical, surgical, environmental, genetic, and psychosocial etiologies. The physical exam begins with the patient’s general appearance, body habitus, and progresses to the genital exam in which the testicles are examined for size, consistency, and location. Prior surgical scars, absence of the vas deferens, or the presence of varicoceles may be identifiable causes of infertility. The semen analysis is the cornerstone laboratory evaluation of the male undergoing an infertility workup. The semen is evaluated for several key parameters including volume as well as sperm concentration, number, motility, and form. An endocrine evaluation is indicated in men with oligospermia, azoospermia, or a history of physical examination findings suggestive of hormonal abnormalities including sexual dysfunction, decreased libido, or physical evidence of impair androgenization. Pending the initial workup genetic testing may be indicated.
