Clinical electroejaculation.

Anejaculation is a disorder that occurs infrequently in the general population, but it occurs in some cases of spinal cord injury and dissection of retroperitoneal lymph nodes for testicular cancer. It is associated with multiple sclerosis, transverse myelitis, and diabetes mellitus. Electroejaculation, which involves electrodes in a probe placed in the rectum, electrically stimulates emission of seminal fluid. Semen thus obtained can be used for artificial insemination if a patient and his spouse wish to become natural parents.
