Ejaculatory duct obstruction (EDO) is a pathological condition which is characterized by the obstruction of one or both ejaculatory ducts. Thus, the efflux of (most constituents of) semen is not possible. It can be congenital or acquired. It is a cause of male infertility and/or pelvic pain.
Each ejaculatory duct is formed by the union of the vas deferens with the duct of the seminal vesicle. [2] They pass through the prostate, and open into the urethra above the seminal colliculus. During ejaculation, semen passes through the prostate gland, enters the urethra and exits the body via the urinary meatus. [3]
In the case of structural retrograde ejaculation, pharmacotherapy might not work but surgical procedures can fix the bladder neck problem. [18] The blockage of the ejaculatory duct can be treated via transurethral resection of the ejaculatory duct (TURED) and is indicated for people with low sperm volume. [19]

Blood in the semen can cause a pink or reddish colour, known as hematospermia, and may indicate a medical problem which should be evaluated by a doctor if the symptom persists. [11] After ejaculation, the latter part of the ejaculated semen coagulates immediately, [12] forming globules, [13] while the earlier part of the ejaculate typically ...
In cartilaginous fish and amphibians, sperm are carried through the archinephric duct, which also partially helps to transport urine from the kidneys. In teleosts , there is a distinct sperm duct, separate from the ureters , and often called the vas deferens, although probably not truly homologous with that in humans. [ 21 ]
Absence of fructose may indicate a problem with the seminal vesicles. The semen fructose test checks for the presence of fructose in the seminal fluid. Fructose is normally present in the semen, as it is secreted by the seminal vesicles. The absence of fructose indicates ejaculatory duct obstruction or other pathology. [5]
The rete testis (/ ˈ r iː t i ˈ t ɛ s t ɪ s / REE-tee TES-tis; pl.: retia testes) is an anastomosing network of delicate tubules located in the hilum of the testicle (mediastinum testis) that carries sperm from the seminiferous tubules to the efferent ducts. It is the homologue of the rete ovarii in females. [1]
