The male accessory glands are the ampullary gland, seminal vesicle, prostate, bulbourethral gland, and urethral gland. [5]The products of these glands serve to nourish and activate the spermatozoa, to clear the urethral tract prior to ejaculation, serve as the vehicle of transport of the spermatozoa in the female tract, and to plug the female tract after placement of spermatozoa to help ensure ...
Internal accessory sex organs to develop and most of these are derived from two systems of embryonic ducts. Male accessory organs are derived from mesonephric (wolfian) ducts. The developing tubules within the testes secretes a polypeptide Müllerian inhibition factor (MIF).
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.
The connective tissue of the prostate is made up of fibrous tissue and smooth muscle. [2] The fibrous tissue separates the gland into lobules. [2] It also sits between the glands and is composed of randomly orientated smooth-muscle bundles that are continuous with the bladder. [11]
The tissue of the seminal vesicles is full of glands, spaced irregularly. [8] As well as glands, the seminal vesicles contain smooth muscle and connective tissue. [8] This fibrous and muscular tissue surrounds the glands, helping to expel their contents. [3] The outer surface of the glands is covered in peritoneum. [3]
m, m. Right and left Müllerian ducts uniting together and running with the Wolffian ducts in gc, the genital cord: m. Müllerian duct, the upper part of which remains as the hydatid of Morgagni; the lower part, represented by a dotted line descending to the prostatic utricle, constitutes the occasionally existing cornu and tube of the uterus ...
Ejaculatory duct obstruction is an acquired or congenital pathological condition in which one or both ejaculatory ducts are obstructed. [9] In the case that both ejaculatory ducts are obstructed, this illness presents with the symptoms of aspermia and male infertility. [9] [10]
There are two types: convoluted and straight, convoluted toward the lateral side, and straight as the tubule comes medially to form ducts that will exit the testis. The seminiferous tubules are formed from the testis cords that develop from the primitive gonadal cords, formed from the gonadal ridge.
