Can Full Grown Man Breastfeed from a New Mother?


Breastfeeding is a natural and essential part of motherhood. It is the process of providing nourishment and sustenance to an infant through the mother’s breast milk. However, in recent years, there has been some speculation about whether or not it is possible for a full-grown man to breastfeed from a new mother. In this article, we will explore the science behind breastfeeding and address this controversial topic.

Understanding Breast Milk Production

Before we can answer the question, it is important to understand how breast milk production works. Hormones play a crucial role in lactation – the process of producing breast milk. During pregnancy, hormonal changes cause the breasts to prepare for milk production. After giving birth, the hormone prolactin stimulates the mammary glands to produce milk. This hormone is triggered by a baby’s suckling and signals the body to make more milk.

Myth or Reality?

The idea of a full-grown man breastfeeding may sound absurd and far-fetched, but there have been cases where it has been reported to happen. Most notably, a man from Sri Lanka claimed to breastfeed from his wife after observing her breastfeeding their newborn child. This case sparked controversy and raised questions about the possibility of male lactation.

The Male Anatomy

As we all know, males do not possess the necessary anatomical features to produce milk and breastfeed. They lack the mammary glands and duct system required for milk production and secretion. Additionally, their hormone levels are significantly different from females, with lower levels of prolactin and oxytocin.

The Science Behind Male Lactation

While there have been rare cases of men producing milk, it is not biologically possible for them to fully lactate like women. Men do have mammary glands and nipples, but they do not have the necessary structures – such as milk ducts and lobules – to produce and store milk. Therefore, even if a man were to mimic the actions of breastfeeding, he would not be able to produce any milk.

The Role of Hormones

As mentioned earlier, hormones play a crucial role in lactation. Men have significantly lower levels of prolactin and oxytocin – the two hormones responsible for milk production – compared to women. Prolactin stimulates milk production while oxytocin helps in its release. Without these hormones produced in adequate amounts, lactation cannot occur.

Inducing Lactation in Men

While male lactation may not be possible naturally, there are methods that can be used to stimulate milk production in men. This process is known as induced lactation and involves the use of hormonal therapy, breast pumping, and herbal supplements. However, these methods have not been scientifically proven to be effective.

Factors Affecting Breastfeeding Ability

There have been some rare cases where men have been able to produce a small amount of milk and breastfeed from their own breasts. This phenomenon, known as male lactation or galactorrhea, is caused by a hormonal imbalance, particularly high levels of prolactin. It can also be induced through certain medications or herbal supplements.

However, even in these cases, the amount of milk produced is minimal and not enough to sustain an adult’s nutritional needs. Additionally, the act of suckling on a nipple also plays a crucial role in breastfeeding. The shape of the infant’s mouth and sucking reflex is specially designed to extract milk from the breast, making it difficult for an adult man to effectively breastfeed.

Challenges and Risks

Even if a man is able to produce milk through induced lactation, there are several challenges and risks involved. Breastfeeding is a physically and emotionally demanding process, and it may not be suitable for men who do not have the necessary lactation support systems in place. Additionally, hormonal therapy can have adverse effects on a man’s overall health.

The Importance of Support

Breastfeeding involves more than just the physical act of feeding a child. It also requires emotional support from partners, family members, and healthcare providers. If a man wishes to take part in the emotional bond of breastfeeding with his partner, it is important for him to have proper support and understanding from those around him.

The Emotional and Social Implications

Apart from the physical limitations, there are also various emotional and social implications to consider when discussing men breastfeeding from a new mother. Breastfeeding is a personal and intimate experience for both the mother and child, with strong bonding and attachment benefits. The act of breastfeeding can also be physically and emotionally taxing for women, especially in the early stages when they are recovering from childbirth.

Moreover, societal norms and stigmas may also play a significant role in how men breastfeeding from a new mother would be perceived. It may be seen as unnatural or even taboo in some cultures, leading to potential social ostracism and emotional distress for both the man and the mother.


In conclusion, while there have been rare cases of men producing milk and even mimicking breastfeeding, it is not biologically possible for them to fully lactate like women. The idea of a full-grown man breastfeeding may seem intriguing or even bizarre, but it is important to base our understanding and beliefs on scientific facts rather than speculation.


Q: Are there any methods or technologies that would enable a full-grown man to breastfeed?

A: No, as of now, there are no known methods or technologies that can alter the biological limitations preventing men from breastfeeding.

Q: Is there any scientific evidence supporting the idea of a full-grown man breastfeeding?

A: No, scientific evidence firmly establishes that breastfeeding is a function exclusive to individuals who possess mammary glands and the necessary hormonal regulation, which are typically females.

Q: Can a full-grown man simulate breastfeeding in any way?

A: While a man cannot produce breast milk, some may engage in skin-to-skin contact or participate in other bonding activities with a newborn, but this does not involve actual breastfeeding.

Q: Are there potential health risks or complications associated with attempting to breastfeed as a full-grown man?

A: Yes, attempting to breastfeed as a man can lead to physical discomfort, infection, and potential psychological distress due to the impossibility of lactation. It’s crucial to recognize the biological differences and seek alternative ways to bond with a newborn.
