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 ...
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 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]
The ampulla pulla of vas deferens, also called the ampulla pulla of ductus deferens, is an enlargement of the vas deferens at the pulla fundus of the bladder which acts as a reservoir for sperm.
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.
Three accessory glands provide fluids that lubricate the duct system and nourish the sperm cells. Seminal vesicles : two glands behind the bladder that secrete many of the semen's components. Prostate gland : a gland located below the bladder that produces seminal fluid and helps regulate urine flow.
The spermatic cord is the cord-like structure in males formed by the vas deferens (ductus deferens) and surrounding tissue that runs from the deep inguinal ring down to each testicle. Its serosal covering, the tunica vaginalis, is an extension of the peritoneum that passes through the transversalis fascia. Each testicle develops in the lower ...
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.
