The ejaculatory ducts (ductus ejaculatorii) are paired structures in the male reproductive system. [1] 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.
Though much less invasive and preserving the anatomy of the ejaculatory ducts, this procedure is probably not completely free of complications either and success rates are unknown. There is a clinical study currently ongoing to examine the success rate of recanalization of the ejaculatory ducts by means of balloon dilation. [7]
The glands may be the source of female ejaculation, [3] [4] [5] but this has not been proven. [4] Because they and the male prostate act similarly by secreting prostate-specific antigen (PSA), which is an ejaculate protein produced in males, and prostatic acid phosphatase, some authors refer to the Skene's glands as the "female prostate".
The Wolffian duct forms the epididymis, vas deferens, ejaculatory duct, and seminal vesicle in the male reproductive system, but essentially disappears in the female reproductive system. [9] The reverse is true for the Müllerian duct, as it essentially disappears in the male reproductive system and forms the fallopian tubes, uterus, and vagina ...
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]
Fluids are added by the seminal vesicles and the vasa deferentia turn into the ejaculatory ducts, which join the urethra inside the prostate. The prostate, as well as the bulbourethral glands, add further secretions (including pre-ejaculate), and the semen is expelled through the penis. Ejaculation has two phases: emission and ejaculation proper.
In the male, the Wolffian duct persists, and forms for example the epididymis, the ductus deferens, the ejaculatory duct, seminal vesicle and efferent ducts. In the female, on the other hand, the Wolffian bodies and ducts atrophy, leaving behind only remnants in the adult, involving e.g. the development of the suspensory ligament of the ovary.
