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.
During the course of the video, the subject's semi-erect penis produces a drop of pre-ejaculate (also known as preseminal fluid, Cowper's fluid, or "pre-cum"); this is the typical amount produced at one time by this subject during arousal. A more thorough demonstration of the viscosity of this fluid can be seen here.
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.
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 ...
Osmoregulation is the active regulation of the osmotic pressure of an organism's body fluids, detected by osmoreceptors, to maintain the homeostasis of the organism's water content; that is, it maintains the fluid balance and the concentration of electrolytes (salts in solution which in this case is represented by body fluid) to keep the body fluids from becoming too diluted or concentrated.
Fluid balance is an aspect of the homeostasis of organisms in which the amount of water in the organism needs to be controlled, via osmoregulation and behavior, such that the concentrations of electrolytes (salts in solution) in the various body fluids are kept within healthy ranges.
However, multiple mates for a female means each individual male has decreased chances of producing offspring. Sperm competition is an evolutionary pressure on males, and has led to the development of adaptations to increase male's chance of reproductive success. [3] Sperm competition results in a sexual conflict between males and females. [2]
Suporn always retains the Cowper's gland or bulbourethral gland. In transgender females this bulbourethral gland is responsible for the thin, colourless lubricating fluid that is secreted during sexual arousal, which also adds to the natural lubrication.
