Secretory fluid from the bulbourethral glands appearing on the glans of a human penis. The bulbourethral gland contributes up to 4 ml of fluid during sexual arousal. [9] The secretion is a clear fluid rich in mucoproteins that help to lubricate the distal urethra and neutralize any acidic urine residue that remains in the urethra.
The membranous urethra or intermediate part of male urethra is the shortest, least dilatable, and, with the exception of the urinary meatus, the narrowest part of the urethra. [citation needed] It extends from the apex of the prostate proximally to the bulb of urethra distally. It measures some 12 mm in length. It traverses the pelvic floor.
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 male urethra enters the penis at the superior aspect of the anterior part of the bulb (most of the bulb is thus situated inferoposteriorly to the urethra), and the arteries of bulb of penis enter near the urethra. [2] The bulb of penis is homologous to the vestibular bulbs in females. [3]
The bulbourethral glands secrete a small amount of clear fluid into the urethra before the ejaculate is expelled. The functions of this fluid are not entirely known but are suggested to aid in lubricating the male urethra in preparation for the semen during ejaculation. [ 4 ]
The bulbourethral glands are present on either side of the membranous urethra and their ducts pierce the perineal membrane posterolateral to the urethra. The deep and dorsal artery of the penis arises from the internal pudendal artery and penetrates the perineal membrane to enter the corpora cavernosa in the crus of the penis.
In human male anatomy, the radix (/ r eɪ. d ɪ k s /) [1] or root of the penis is the internal and most proximal portion of the human penis that lies in the perineum.Unlike the pendulous body of the penis, which is suspended from the pubic symphysis, the root is attached to the pubic arch of the pelvis and is not visible externally.
