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 ...
The root of the penis begins directly below the bulbourethral glands, or Cowper glands, and consists of three long masses of tissue; the bulb and the crura.The bulb of the penis is an enlarged mass of erectile tissue that is located in the midline of the root and is traversed by the male urethra.
William Cowper FRS (/ ˈ k uː p ər / KOO-pər; c. 1666 – 8 March 1709) was an English surgeon and anatomist, famous for his early description of what is now known as Cowper's gland. Cowper was born in Petersfield, Hampshire , and he was apprenticed to a London surgeon, William Bignall, in March 1682.
Pre-ejaculate (also known as pre-ejaculatory fluid, pre-seminal fluid or Cowper's fluid, and colloquially as pre-cum) is a clear, colorless, viscous fluid that is emitted from the urethra of the penis during sexual arousal and in general during sexual activity. It is similar in composition to semen but has distinct chemical differences.
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 openings of the bulbourethral glands are also found here. [13] Some textbooks will subdivide the spongy urethra into two parts, the bulbous and pendulous urethra. The urethral lumen runs effectively parallel to the penis, except at the narrowest point, the external urethral meatus, where it is vertical.
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]
