ANEJACULATIO

Anejaculation is the pathological inability to ejaculate despite an erection[1] in males, with (orgasmic) or without (anorgasmic) orgasm.

Causes: 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

• 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

Anejaculation, especially the orgasmic variant, is usually indistinguishable from retrograde ejaculation. However, a negative urinalysis measuring no abnormal presence of spermatozoa in the urine will eliminate a retrograde ejaculation diagnosis. 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
