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]
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]
Retrograde ejaculation; This type of ejaculation happens when there is a defect on prostate, so the sample is not ejaculated outside but to the bladder. So, in that case, what we have to do to obtain the sample is: – Intake bicarbonate, about 25 grams, the night before and the morning of the sample obtaining.
Balloon dilatation or transurethral ejaculatory duct resection are two treatments for ejaculatory duct obstruction. [27] In one study, tamsulosin-treated patients' symptoms significantly improved after four weeks of treatment. [5] This is also helpful for painful ejaculation following radical prostatectomy. [5]
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]
Fluid is secreted from the ejaculatory ducts of the vesicles into the vas deferens, where it becomes part of semen. This then passes through the urethra, where it is ejaculated during a male sexual response. [9] About 70-85% of the seminal fluid in humans originates from the seminal vesicles. [11]
