the absence from the semen of spermatozoa and cellular elements of the seminal vesicles. Aspermia is one of the causes of male sterility. The causes of aspermia are the disturbance of the passageways of the vas deferens as a result of the inflammation of the appendages of the testicles (epididymis), traumatic injury of the vas deferens, and developmental defect of the vas deferens. Unlike as-permatism, aspermia does not affect ejaculation or orgasm.

Treatment is directed at the elimination of the causes of aspermia and involves physiotherapeutic measures, tissue therapy to soften and resolve the scarred tissue, and hormone therapy. If conservative treatment is unsuccessful, a restorative operation can be performed.
