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 observable, visual differences become apparent between male or the female reproductive organs are not seen initially.
The prostate is the only male accessory gland that occurs in cetaceans, [68] consisting of diffuse urethral glands [69] surrounded by a very powerful compressor muscle. [70] The prostate gland originates with tissues in the urethral wall.

The seminal vesicles (also called vesicular glands [1] or seminal glands) are a pair of convoluted tubular accessory glands that lie behind the urinary bladder of male mammals. They secrete fluid that largely composes the semen. The vesicles are 5–10 cm in size, 3–5 cm in diameter, and are located between the bladder and the rectum.
Most species of placental mammals have bulbourethral glands, but they are absent in Caniformia and Cetacea. They are the only accessory reproductive glands in male monotremes. Placental mammals usually have one pair of bulbourethral glands, [3] while male marsupials have 1–3 pairs. [3] [4] [5] Of all domesticated animals, they are absent only ...
Seminal fluid continues down the ejaculatory duct into the prostate gland, where an alkaline prostatic fluid is added. [4] This addition provides the texture and odor associated with semen. [ 4 ] The alkalinity of the prostatic fluid serves to neutralize the acidity of the female vaginal tract in order to prolong the survival of sperm in this ...
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.
