Chlamydia: The bacteria that causes chlamydia, Chlamydia trachomatis, trigger inflammation of the reproductive tract, leading to PID in women and epididymitis (inflammation of the epididymis) in men.
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.
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.
Vasoepididymostomy connects the end of the vas deferens tube on each side of the scrotum directly to the epididymis on the same side.
If they do not pass through the epididymis in the normal way, sperm may not work normally.
The epididymis is a convoluted, tubelike structure that sits on the edge of the testicle.
It involves using a needle to take sperm directly from the epididymis or the testicle.
The vas deferens tube emerges from the epididymis.
Is the homologue of the male epididymis and vas deferens.
