If both ejaculatory ducts are completely obstructed, affected men will demonstrate male infertility due to aspermia/azoospermia.They will suffer from a very low volume of semen which lacks the gel-like fluid of the seminal vesicles or from no semen at all while they are able to have the sensation of an orgasm during which they will have involuntary contractions of the pelvic musculature.
Each ejaculatory duct is formed by the union of the vas deferens with the duct of the seminal vesicle. [2] They pass through the prostate, and open into the urethra above the seminal colliculus. During ejaculation, semen passes through the prostate gland, enters the urethra and exits the body via the urinary meatus. [3]
Common inherited variants in genes that encode enzymes employed in DNA mismatch repair are associated with increased risk of sperm DNA damage and male infertility. [39] As men age there is a consistent decline in semen quality, and this decline appears to be due to DNA damage. [40]

Fluids are added by the seminal vesicles and the vasa deferentia turn into the ejaculatory ducts, which join the urethra inside the prostate. The prostate, as well as the bulbourethral glands, add further secretions (including pre-ejaculate), and the semen is expelled through the penis. Ejaculation has two phases: emission and ejaculation proper.
The blockage of the ejaculatory duct can be treated via transurethral resection of the ejaculatory duct (TURED) and is indicated for people with low sperm volume. [19] TURED has been shown to improve the volume of semen in men with ejaculatory duct obstruction leading to significant improvement in the fertility rate. [20]
Balloon dilatation or transurethral ejaculatory duct resection are two treatments for ejaculatory duct obstruction. [27] In one study, tamsulosin-treated patients' symptoms significantly improved after four weeks of treatment. [5] This is also helpful for painful ejaculation following radical prostatectomy. [5]
Reflux of sterile urine (urine without bacteria) through the ejaculatory ducts may cause inflammation with obstruction. In children, it may be a response following an infection with enterovirus, adenovirus or Mycoplasma pneumoniae. Rare non-infectious causes of chronic epididymitis include sarcoidosis (more prevalent in black men) and Behçet's ...
