Though urinary tract infections in men are rare, bacterial infection is the most common cause of acute epididymitis. [6] The bacteria in the urethra back-track through the urinary and reproductive structures to the epididymis. In rare circumstances, the infection reaches the epididymis via the bloodstream. [7]
The vas deferens may be obstructed, or it may be completely absent in a condition known as congenital absence of the vas deferens (CAVD, a potential feature of cystic fibrosis), causing male infertility. Acquired obstructions can occur due to infections.
Male accessory gland infection (MAGI) is a condition with signs of inflammation involving one or more sites in the male genital tract. Diagnosis is made according to parameters defined by the World Health Organization , and it is particularly made in relation to infectious or inflammatory causes of male infertility .
During a vasectomy procedure, a surgeon will typically cut the vas deferens — the tubes that transport sperm to the ducts, and use other techniques to prevent sperm transport through the tubes.
[13] [14] Stones or cysts that become infected, or obstruct the vas deferens or seminal vesicles, may require surgical intervention. [9] Seminal vesiculitis (also known as spermatocystitis) is an inflammation of the seminal vesicles, most often caused by bacterial infection. [15]
Post-testicular factors decrease male fertility due to conditions that affect the male genital system after testicular sperm production and include defects of the genital tract as well as problems in ejaculation: [citation needed] Vas deferens obstruction; Lack of Vas deferens, often related to genetic markers for cystic fibrosis
Reproductive tract infection (RTI) are infections that affect the reproductive tract, which is part of the reproductive system.For females, reproductive tract infections can affect the upper reproductive tract (fallopian tubes, ovary and uterus) and the lower reproductive tract (vagina, cervix and vulva); for males these infections affect the penis, testicles, urethra or the vas deferens.
