Nipples! Almost everyone has them, whether you’re a boy or a girl. They help moms feed their babies and can be important in close relationships. Just like any other part of our bodies, nipples have some fascinating facts. Let’s dive into some unusual facts about male nipples!
Both men and women have nipples because of how babies develop before they’re born. When a baby is growing in the womb, several genes decide if it will be a boy or a girl. One important gene, called the SRY gene, starts working about seven weeks into development. This gene helps form male reproductive organs, while female ones stop growing. But nipples and the area around them form before this gene starts working, so almost everyone ends up with nipples.
Believe it or not, male nipples can produce milk, but it’s very rare. Usually, men don’t have enough of a hormone called prolactin, which is needed to make milk. However, certain conditions, like hypothyroidism or some medications, can increase prolactin levels in men. There’s not much research on whether men’s milk is like women’s milk, but some studies suggest it might have similar nutrients.
Nipples can be sensitive, and for some people, touching them can feel nice. While many don’t think of male nipples as sensitive areas, stimulating them can activate parts of the brain similar to those activated by touching other sensitive areas. This can increase feelings of excitement.
During activities like running, nipples can get sore and even bleed because of friction. This happens when skin rubs against clothes or itself. To prevent this, runners can try wearing special nipple guards or clothes made from materials that reduce friction, like synthetic or moisture-wicking fabrics.
Did you know that about one percent of men have a third nipple? These extra nipples, called supernumerary nipples, can appear along a line from the armpit to the genitals. They can look different, sometimes having areolas and breast tissue, and sometimes not. They are usually harmless but can be removed if someone doesn’t like how they look.
Men can get breast cancer, although it’s rare. About 2,400 men are diagnosed each year. Signs include a lump, skin changes, or nipple discharge. It’s important for men to know these signs and see a doctor if they notice anything unusual.
Gynecomastia is when men develop more breast tissue due to hormone changes. It’s not usually serious but can be uncomfortable. There are treatments available if needed.
Some men have inverted or oversized nipples, which can be fixed with surgery if desired. There are even world records related to nipples, like the heaviest weight lifted by nipples and the longest nipple hair!
Montgomery glands are small glands in the nipple area that help keep the skin healthy and protect against germs. They were named after an Irish doctor.
Finally, male nipples can sometimes be injured in unexpected ways. For example, there was a case where a zebra bit off part of a man’s nipple while he was working outside!

Research and create a timeline showing the stages of fetal development, focusing on when and how nipples form. Include the role of the SRY gene and how it affects the development of male and female characteristics. Present your timeline to the class.
Investigate the hormone prolactin and its role in milk production. Create a short report or presentation explaining how prolactin affects both males and females, and under what conditions male nipples might produce milk. Share your findings with your classmates.
Conduct a simple experiment to understand sensitivity. Use different textures (like cotton, wool, and silk) to gently rub on your forearm and note the sensations. Discuss how sensitivity might vary across different body parts, including nipples, and why this might be the case.
Design a prototype of a nipple guard for athletes. Consider materials that reduce friction and are comfortable to wear. Present your design to the class, explaining how it helps prevent chafing during physical activities.
Create a poster or digital presentation to raise awareness about male breast cancer and gynecomastia. Include signs to watch for and encourage regular health checks. Share your campaign with the school to educate others about these important health issues.

Nipples! Almost everyone has them, regardless of gender. They allow mothers to feed their babies and can play a role in intimacy. Like every other part of the human body, nipples can be quite interesting. In this episode of the Infographics Show, we’re exploring unusual facts about male nipples!
Both men and women have nipples due to the way embryos develop. Several genes determine if a baby is male or female, including the SRY gene, which is activated around seven weeks into development. This gene leads to the formation of male reproductive organs while female ones regress. Breasts and nipples form before the SRY gene activates, which is why almost everyone has nipples and a mammary ridge.
Now, let’s discuss male nipples! Male nipples can lactate, although this is rare. Generally, men don’t produce enough prolactin, the hormone that stimulates milk production. However, prolactin levels can increase in men due to conditions like hypothyroidism or certain medications. There’s limited research on whether the milk produced by men has similar properties to women’s breast milk, but some studies suggest it may have comparable concentrations of lactose, proteins, and electrolytes.
Nipples can also be sensitive. While many don’t consider male nipples to be erogenous zones, stimulation can activate similar brain areas as genital stimulation, enhancing sexual arousal. Research has shown that the brain areas activated by nipple stimulation in women correspond to those in men.
Nipples can chafe and bleed during physical activities, a common issue for runners. This chafing occurs due to friction from skin rubbing against itself or clothing. To avoid chafing, runners can try removing their shirts or using nipple guards designed for this purpose. Wearing synthetic or moisture-wicking fabrics can also help minimize irritation.
Did you know that about one percent of men have a third nipple? Known as supernumerary nipples, this condition can result in one or more extra nipples on the body. It’s estimated that around 200,000 Americans have extra nipples, which can appear along the “milk line” that runs from the armpit to the genitals.
Extra nipples can be categorized based on their characteristics, ranging from those with areolas and breast tissue to those without. The appearance of third nipples is linked to embryonic development, specifically the thickening of the milk lines during pregnancy.
While third nipples are generally harmless, they can be removed for cosmetic reasons. Interestingly, they can also lactate like regular nipples.
In media, female nipples are often censored, while male nipples are not. This discrepancy has historical roots, with male nudity often embodying virtues like strength, while female nudity has been more sexualized.
Men can also develop breast cancer, though it’s rare. Approximately 2,400 men are diagnosed each year. Symptoms may include a painless lump, changes in the skin, or discharge from the nipple. It’s essential for men to be aware of these signs and consult a doctor if they notice any changes.
Gynecomastia, an increase in breast gland tissue in males, can occur due to hormonal imbalances. While it’s not usually serious, it can cause discomfort and affect self-esteem. Treatment options are available if needed.
Men can also experience inverted or oversized nipples, which can be corrected through surgery.
Interestingly, there are world records related to nipples, including the heaviest weight lifted by nipples and the longest nipple hair.
Montgomery glands, small sebaceous glands in the nipple and areola, were named after an Irish obstetrician. These glands help lubricate the skin and protect against germs.
Lastly, male nipples can be subject to unexpected injuries. For example, there was an incident where a zebra bit off part of a man’s nipple while he was working in a yard.
