ejaculatory duct , auch: sperm duct

Another underlying cause for this phenomenon may be ejaculatory duct obstruction.

Ejaculatory ducts are part of the human male anatomy.

Ejaculatory duct obstruction is the underlying cause for 1 - 5% of male infertility.

In Addition, calculus (medicine) was reported to mechanically block the ejaculatory duct, leading to infertility.

Anteriorly, the long and highly coiled, muscular ejaculatory duct arises from the prostate.

This damage is most often seen within 0.5 cm of the ejaculatory duct (usually distal to the duct).

The prostate gland surrounds the ejaculatory ducts at the base of the urethra, just below the bladder.

The third part of the duct system are the ejaculatory ducts which are one inch long paired tubes that pass through the prostate gland.

Since ejaculatory duct obstruction is a relatively rare cause of infertility, this possibility may be unfamiliar to some physicians, even some urologists.

Reflux of sterile urine (urine without bacteria) through the ejaculatory ducts may cause inflammation with obstruction.

The ejaculatory ducts (ductus ejaculatorii) are paired structures in male anatomy.

Ejaculatory duct obstruction must not be confused with an obstruction of the vas deferens.

This duct joins the ejaculatory duct, which extends through the prostate gland, and enters the upper segment of the urethra.

The median lobe of the prostate is formed as an extension of the lateral lobes between the common ejaculatory ducts and the bladder.

The ejaculatory duct is derived from an invagination of the epidermal cells during development and, as a result, has a cuticular lining.

It consists of a long shaft, the truncus, and a terminal capsule called glans, containing the stylus and ejaculatory duct.
