• Absence of Ejaculation
The absence of ejaculation may occur due to a abnormality in the production or storage of sperm, or conditions that affect the expulsion process. Psychological causes are common, but, if the man never ejaculated, you should suspect of organic causes. Congenital anomalies such as absence of seminal vesicles and prostate gland may be responsible, although this is very rare. There are cases which this absence comes from side effects from surgeries (such as cancer surgeries) with damage to the sympathetic trunk. Radical prostatectomy usually results in the loss of ejaculation, despite the secretions from glands for urethral can cause small emissions. The orgasmic sensations are normal, but there is no expulsion of the semen. Patients with distal neuropathy, especially diabetics and patients with other neuromuscular diseases such as multiple sclerosis, can present “aspermia” lack of contraction of the epididymis, vas deferens, seminal vesicles and prostate. The absence of ejaculate may also be due to not training material needed for ejaculation. In case of absence of ejaculate or decrease of the same should be evaluated retrograde ejaculation hypothesis.
