Exempel på deferens

• Correlation between epididymal length and fertilization rate in men with congenital absence of the vas deferens.

• Prolonged sojourn in the cauda epididymis (and vas deferens), however, could be detrimental to the spermatozoa.

• The paired microtestes then fuse to give origin to the vas deferens.

• Experiments are now going on with the insertion of a plug into the vas deferens rather than the cutting of the duct itself.

• Backpressure from blockage of the vas deferens causes a rupture in the epididymis, called an epididymal blowout, in over half of vasectomy patients.

• Two procedures are possible at the time of vasectomy reversal: vasovasostomy (vas deferens to vas deferens connection) and vasoepididymostomy (epididymis to vas deferens connection).

• There are several nerves that run parallel to the vas deferens that may be cut or damaged during vasectomy.

• Clamping the vas deferens can produce muscle disruption and fibrosis.

• Testosterone converts the mesonephric ducts into male accessory structures, including the epididymis, vas deferens, and seminal vesicle.

• Male defects have included epididymal cysts, agenesis of the vas deferens, or infertility due to abnormal spermatozoa.

• Each opens in a vas deferens which bears three diverticula or "vesiculae seminales".

• The vas deferens is also known as ductus deferens, and is a muscular tube that begins at the lower end of the epididymis.

• The paired mesonephric ducts in the male, in contrast, go on to form the paired epididymis, ductus deferens, ejaculatory duct and seminal vesicle.

• The polymer has magnetoelastic behavior that allow it to stretch and elongate to better line the vas deferens.

• The short posterior-leading vas deferens joins the large, tubular prostate gland.
