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. [6] 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.
Homologous structures in the external genitalia. 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 ...

Ejaculation occurs in two stages, the emission stage and the expulsion stage. [4] The emission stage involves the workings of several structures of the ejaculatory duct; contractions of the prostate gland, the seminal vesicles, the bulbourethral gland and the vas deferens push fluids into the prostatic urethra. [3]
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 bulb of penis is the proximal/posterior bulged [1] end of the (unpaired median) corpus spongiosum penis.Together with the two crura (one crus on each side of the bulb), it constitutes the root of the penis. [2]
The second category are the ejaculatory fluid producing glands which include the Cowper's gland (also called bulbourethral gland), seminal vesicles, prostate, and vas deferens. The final category are those used for copulation and deposition of the sperm within the female; these include the penis, urethra, and vas deferens. [3]
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.
