noun
definition
A narrow, tightly-coiled tube connecting the efferent ducts from the rear of each testicle to its vas deferens, where sperm are stored during maturation.
Examples of epididymis in a Sentence
The vas deferens tube emerges from the epididymis.
The tumors of the bilateral epididymis were surgically resected and of the right renal tumor enucleated.
Expression was negligible in rete testis and interstitial Leydig cells, and low in epididymis.
Vasoepididymostomy connects the end of the vas deferens tube on each side of the scrotum directly to the epididymis on the same side.
The epididymis is a convoluted, tubelike structure that sits on the edge of the testicle.
Vasoepididymostomy is done when an obstruction in the vas deferens close to the epididymis, or in the epididymis itself, is stopping sperm from getting through.
Success rates are lower than for vasovasotomy partly because sperm must be processed in the epididymis in order to be able to fertilize an egg.
If they do not pass through the epididymis in the normal way, sperm may not work normally.
If the first surgery left the vas deferens very short, or if there appears to be scar tissue near the epididymis, the second attempt may be the more complicated vasoepididymostomy.
It involves using a needle to take sperm directly from the epididymis or the testicle.
This time the choices were to remove the epididymis or to remove the right testicle.
