On the shaft of the penis, Fordyce spots are more visible when the skin is stretched, and may only be noticeable during an erection. [8] The spots can also appear on the skin of the scrotum. [8] Oral Fordyce granules appear as rice-like granules, white or yellow-white in color.
Penile cancer is a rare cancer in developed nations, with annual incidence varying from 0.3 to 1 per 100,000 per year, accounting for around 0.4–0.6% of all malignancies. [4] The annual incidence is approximately 1 in 100,000 men in the United States, [ 28 ] 1 in 250,000 in Australia, [ 29 ] and 0.82 per 100,000 in Denmark. [ 30 ]
Fordyce's spots are small, raised, yellowish-white spots 1–2 mm (less than an inch) in diameter that may appear on the penis, which again are common and not infectious. Sebaceous prominences are raised bumps similar to Fordyce's spots on the shaft of the penis, located at the sebaceous glands and are normal.
They are usually considered as vestigial remnants of penile spines, sensitive features found in the same location in other primates. [6] [7] They do not spread and often spontaneously regress. [8] Along with Fordyce glands PPPs secrete oils to keep the skin of the head of the penis in good condition. [9]

The three most statistically frequently occurring diseases of the prostate gland are benign hyperplasia (a swelling of the gland, not due to cancerous accumulation), prostatitis (inflammation), and cancer [6] (which is the accumulation of malignant cells in the gland). [7]
GnRH nudges the pituitary gland to produce luteinizing hormone (LH) and follicle-stimulating hormone (FSH). LH calls on the Leydig cells (also in the testes) to make testosterone.
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.
