Hirsuties coronae glandis

Hirsuties coronae glandis, also known as hirsutoid papillomas or pearly penile papules (PPP), are small, benign protuberances that can form on the ridge of the glans (head) of the human penis. These papules are considered a normal anatomical variation and are not associated with any sexually transmitted infections or diseases.

Corona of Glans Penis

Characteristics and Causes

• PPP are a form of acral angiofibromas, which are benign skin lesions composed of blood vessels and connective tissue.
• They appear as small, flesh-colored or white, dome-shaped bumps that usually form in one or more rows around the corona (ridge) of the glans penis.
• PPP are more common in uncircumcised men, and their prevalence ranges from 14% to 48% in various populations.
• The exact cause of PPP is unknown, but they are thought to be a normal variation in human anatomy and not related to any disease or infection.

Relation to Penile Spines

• Pearly penile papules have been described as vestigial remnants of penile spines, which are sensitive features found in the same location in other primates.
• In species where penile spines are expressed, as well as in humans who have them, the spines are thought to contribute to sexual pleasure and quicker orgasms.
• It has been theorized that pearly penile papules stimulate the vagina during sexual intercourse, although there is limited scientific evidence to support this claim.

Function and Secretions

Pearly penile papules may have a functional role in maintaining the moisture of the glans penis. They are capable of secreting oil that helps keep the glans moist and may provide some lubrication during sexual activity.

Treatment and Management

• Pearly penile papules are harmless and typically do not require treatment.
• They are not contagious and cannot be transmitted to a partner during sexual activity.
• If a man is concerned about the appearance of PPP or feels that they are causing psychological distress, he can consult with a dermatologist or urologist to discuss possible treatment options, such as cryotherapy, laser therapy, or excision.

Summary

Hirsuties coronae glandis (also known as hirsutoid papillomas and pearly penile papules; PPP) are small protuberances that may form on the ridge of the glans of the human penis. They are a form of acral angiofibromas. They are a normal anatomical variation in humans and are sometimes described as vestigial remnants of penile spines, sensitive features found in the same location in other primates. In species in which penile spines are expressed, as well as in humans who have them, the spines are thought to contribute to sexual pleasure and quicker orgasms. It has been theorized that pearly penile papules stimulate the vagina during sexual intercourse. In addition, pearly penile papules secrete oil that moistens the glans of the penis.
