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.
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 ...
[2] [3] Although there remains debate about the function of the Skene's glands, one purpose is to secrete a fluid that helps lubricate the urethral opening. [2] [3] Skene's glands produce a milk-like ultrafiltrate of blood plasma. The glands may be the source of female ejaculation, [3] [4] [5] but this has not been proven. [4]

The prostatic secretion, influenced by dihydrotestosterone, is a whitish (sometimes clear), thin fluid containing proteolytic enzymes, citric acid, acid phosphatase and lipids. [5] The bulbourethral glands secrete a clear secretion into the lumen of the urethra to lubricate it.
Made up of olfactory receptors and glands, the epithelium is used as a tool to smell others' body odour and pheromones. [10] Chemicals that produce odour pass through the olfactory epithelium to the olfactory bulbs , which contain biological receptors that detect the chemicals, and respond with an electrical signal transmitted to the brain by ...
the salivary glands of the tongue [2] the liver; the lacrimal glands; the mammary glands; the pancreas [3] the bulbourethral (Cowper's) glands; The thyroid follicles can also be considered of acinar formation but in this case the follicles, being part of an endocrine gland, act as a hormonal deposit rather than to facilitate secretion.
