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.
This category reflects the organization of International Statistical Classification of Diseases and Related Health Problems, 10th Revision. Generally, diseases outlined within the ICD-10 codes N40-N51 within Chapter XIV: Diseases of the genitourinary system should be included in this category.
The main male sex organs are the penis and the scrotum, which contains the testicles that produce semen and sperm, which, as part of sexual intercourse, fertilize an ovum in the female's body; the fertilized ovum develops into a fetus, which is later born as an infant. The corresponding system in females is the female reproductive system.
The vas deferens (pl.: vasa deferentia), ductus deferens (pl.: ductūs deferentes), or sperm duct is part of the male reproductive system of many vertebrates. In mammals, spermatozoa are produced in the seminiferous tubules and flow into the epididymal duct. The end of the epididymis is connected to the vas deferens.
This list of related male and female reproductive organs shows how the male and female reproductive organs and the development of the reproductive system are related, sharing a common developmental path. This makes them biological homologues. These organs differentiate into the respective sex organs in males and females.
A male genital disease is a condition that affects the male reproductive system. The human male genitals consist of testicles and epididymides , ductus deferentes , seminal vesicles and ejaculatory ducts , prostate , bulbourethral glands , and penis .
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 ...
Each lobule consists of a number of acini, lined by columnar epithelial cells, opening into a duct that joins with the ducts of other lobules to form a single excretory duct. This duct is approximately 2.5 cm long and opens into the bulbar urethra at the base of the penis. The glands gradually diminish in size with advancing age.
