A.—Diagram of the primitive urogenital organs, from 'Diagrams to show the development of male and female generative organs from a common type' * w, w. Right and left Wolffian ducts. The observable, visual differences become apparent between male or the female reproductive organs are not seen initially.
The prostatic utricle (Latin for "small pouch of the prostate") is a small indentation in the prostatic urethra, at the apex of the urethral crest, on the seminal colliculus (verumontanum), laterally flanked by openings of the ejaculatory ducts.
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 ...
In some marsupial species, the size of the prostate gland changes seasonally. [64] The prostate is the only accessory gland that occurs in male dogs. [65] Dogs can produce in one hour as much prostatic fluid as a human can in a day. They excrete this fluid along with their urine to mark their territory. [66]
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 ...

It runs almost vertically through the prostate from its base to its apex, lying nearer its anterior than its posterior surface; the form of the canal is spindle-shaped, being wider in the middle than at either extremity, and narrowest below, where it joins the membranous portion.
