What Are the Functions of Nipples in Men and Women, and Why Do They Sometimes Hurt?

Question

I recently noticed some sensitivity in my nipples, and it made me curious about their function and why they sometimes become irritated. I always associated nipples with breastfeeding in women, but now I’m wondering—what is the purpose of nipples in both men and women, and what causes them to become sore or painful?

From what I understand, nipples contain nerve endings and ducts that are important for lactation in women. But why do men have nipples, and do they serve any function beyond being a leftover evolutionary trait?

I also read that sore nipples can be caused by friction from clothing, hormonal changes, or even underlying health conditions. How do you know if nipple pain is normal or if it’s a sign of something more serious like an infection or hormonal imbalance?

Since I prefer natural health solutions, I looked into Ayurveda’s approach to skin and breast health. Are there Ayurvedic treatments, oils, or herbal remedies that can help soothe nipple pain and sensitivity? I found that coconut oil, turmeric, and Triphala are often recommended—do these actually help with irritated or dry nipples?

For those who have experienced nipple pain or sensitivity, what was the cause in your case? Did home remedies, medical treatments, or lifestyle changes help the most? I’d love to hear real experiences about nipple health and natural ways to manage discomfort.

Nipples are highly sensitive structures present in both men and women, primarily serving a role in breastfeeding for women. In men, they exist due to early fetal development, where all embryos initially develop with the potential for breasts, but males do not produce the necessary hormones for lactation. While nipples in men don’t have a direct biological function, they contain nerve endings that contribute to sensitivity and sexual arousal.

Nipple sensitivity or pain can be caused by friction from clothing, hormonal fluctuations, allergic reactions, infections, or even underlying health conditions. In women, hormonal shifts during menstruation, pregnancy, or breastfeeding can cause tenderness. In men, hormonal imbalances, such as increased estrogen levels, might lead to sensitivity or swelling. Other causes include eczema, fungal infections, or even gynecomastia (enlargement of male breast tissue). If nipple pain is persistent, comes with discharge, redness, or swelling, it’s best to seek medical advice to rule out infections or hormonal disorders.

Ayurveda offers natural remedies for soothing nipple sensitivity and maintaining breast health. Coconut oil and turmeric are known for their anti-inflammatory and moisturizing properties, helping with dryness and irritation. Triphala is often used internally to balance hormones and improve skin health. Applying aloe vera gel, ghee, or castor oil may also provide relief from discomfort.
