Aspermatism (aspermatismus; a - negative part + Greek sperma, spermatos - sperm, semen) - absence of ejaculation during intercourse.
The following types of aspermatism are distinguished:
Artificial (artificialis) - occurs after the operation of vasoligature;
True (verus; synonym: neuropsychic aspermatism) - occurs due to violations of the ejection of sperm into the lumen of the urethra against the background of neuropsychic disorders;
False (spurius) - due to high viscosity of semen, impaired patency of the urethra, or throwing it into the lumen of the bladder against the background of atony of the internal sphincter;
Mechanical (mechanicus) - false aspermatism, caused by acquired or congenital anomalies of the urethra;
Neuroreceptor (outdated; neuroreceptorius) - true aspermatism, caused by complete loss or decreased sensitivity of the nerve endings of the urethra and body, as well as the glans penis;
Psychogenic (psychogenus; synonym: cortical aspermatism, obsolete.) - true aspermatism, due to the inhibitory effect on the ejaculatory reflex of any mental factors, for example, emotional;
Spinal (spinalis) - true aspermatism, caused by damage to the spinal cord.
