Anejaculation
Anejaculation is the pathological inability to ejaculate despite an erection in males, with or without orgasm.
Causes
It can depend on one or more of several causes, including:- Sexual inhibition
- Pharmacological inhibition. They include mostly antidepressant and antipsychotic medication, and the patients experiencing that tend to quit them
- Autonomic nervous system malfunction
- Prostatectomy - surgical removal of the prostate.
- Ejaculatory duct obstruction
- Sexuality after [spinal cord injury|Spinal cord injury causes sexual dysfunction] including anejaculation. The rate of being able to ejaculate varies with the type of lesion, as detailed in the table at right.
- Old age
- Diabetes mellitus
Thus, if the affected person has the sensations and involuntary muscle-contractions of an orgasm but no or very low-volume semen, ejaculatory duct obstruction is another possible underlying pathology of anejaculation.
