Įjaculatory duct obstruction may result in a complete lack of semen ( aspermia) or a very low-volume semen ( oligospermia) which may contain only the secretion of accessory prostate glands downstream to the orifice of the ejaculatory ducts. In case of proven fertility but unresolved pelvic pain, even one or both partially obstructed ejaculatory ducts may be the origin of pelvic pain and oligospermia. In addition, it is reported to be a cause for pelvic pain, especially shortly after ejaculation. This is contrary to some other forms of anejaculation. 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. If both ejaculatory ducts are completely obstructed, affected men will demonstrate male infertility due to aspermia/ azoospermia. Ejaculatory duct obstruction must not be confused with an obstruction of the vas deferens. It is a cause of male infertility and/or pelvic pain.
Thus, the efflux of (most constituents of) semen is not possible.
Medical condition Ejaculatory duct obstructionĮjaculatory duct obstruction ( EDO) is a pathological condition which is characterized by the obstruction of one or both ejaculatory ducts.
