WTF Fun Fact 13273 – Men’s Nipples Lactate

It’s extremely rare unless something is wrong with the body, but technically, men’s nipples lactate. That is, they are capable of producing milk, which is the function of a nipple.

All fetuses develop nipples. Male, female, and intersex fetuses develop nipples during the early stages of fetal development, typically around 6 to 7 weeks gestation. This is because nipples are a fundamental part of the human anatomy. It is only later in fetal development that sex-specific features begin to emerge, such as the development of genitalia.

How, when, and why do men’s nipples lactate?

While lactation in men is a rare occurrence, it is not something that should be dismissed as a mere anomaly. Despite being uncommon, men can and do produce breast milk in certain circumstances. For example, it may happen during hormonal imbalances or after frequent stimulation of the nipples. This phenomenon has been documented in a variety of mammalian species, including humans. Yet much remains to be understood about the underlying biology and mechanisms driving male lactation.

Male lactation is also known to occur in response to the hormonal changes brought about by certain medical conditions. For example, in some cases, male lactation is triggered when a man experiences a rise in the hormone prolactin.

The role of prolactin

The hormone responsible for milk production in females plays a similar role in males. Prolactin stimulates milk production in the mammary glands, and in males, it is secreted by the anterior pituitary gland.

However, the prolactin levels in males are much lower than in females. This is why milk production in males is rare, and the amount produced is usually not enough to sustain an infant. The biology involved in male lactation involves the mammary glands, which are present in both men and women.

While these glands are not fully developed in men, they still have the potential to produce milk. The process of male lactation can also be triggered by stress, certain medications, or a tumor in the pituitary gland.

Stimulating lactation in men

Another cause of male lactation is the use of medications that can mimic the hormonal effects of pregnancy and breastfeeding. For example, medications containing estrogen can cause an increase in prolactin production, leading to milk production in men’s mammary glands.

Despite the rarity of male lactation, some men have been able to nurse their infants successfully. One example is a man named Jack Newman. After adopting a child, Newman was able to induce lactation through a combination of hormone treatments and frequent nursing sessions.

Male lactation may seem like a strange and abnormal occurrence. But the rare phenomenon of male lactation is a fascinating subject. And it has captured the interest of scientists and laypeople alike. While much remains to be discovered, continued research into male lactation could have significant implications for our understanding of infant nutrition and lactation science as a whole. The underlying mechanisms that allow men to produce milk could help to improve our understanding of the biology of lactation in general. This could lead to breakthroughs in lactation-related issues such as mastitis and low milk supply.

Despite these potential benefits, male lactation remains a largely unexplored field of study.

WTF Fun Fact 13204 – Types of Cheese in the World

Believe it or not, there are over 1,800 types of cheese in the world. actually has a catalog of 1,830 cheeses you can search!

How can there be so many cheeses in the world?

There are so many types of cheese in the world because cheese-making is an ancient craft. Humans have been making cheese for thousands of years in many different cultures and regions. The process of making cheese is relatively simple. It only requires milk, cultures, rennet, and salt. But there are many variations on this basic recipe.

Different types of milk, cultures, rennet, aging, and processing methods result in a wide variety of textures and flavors.

Additionally, different regions have developed their own unique cheeses based on the availability of milk and the local culture and traditions. The use of different herbs, spices, and other ingredients also contributes to the diversity of cheese.

Additionally, the development of new technology and techniques in cheesemaking also allows cheese makers to experiment and create new types of cheese.

What are the different types of cheese?

We can make cheese from the milk of various animals, including cows, goats, sheep, and buffalo, and it comes in a wide variety of textures and flavors.

Some types of cheese, such as cheddar and gouda, can be aged for several years, which gives them a sharper flavor and a harder texture. Other types, such as feta and brie, are typically aged for a shorter period of time and have a softer texture and a milder flavor.

According to Wisconsin Cheese (cited below): “Many different types of cheese are named after or associated with the place they were first made. Parmesan cheese, for example, originates from the area around Parma, Italy. Gouda was first traded in the Dutch town of Gouda. And cheddar cheese originated in the English village of Cheddar in Somerset.”

WTF Fun Fact 12618 – Pauline, The Presidential Cow

Until the late 19th century, presidents brought their own cows to the White House to provide milk. There was no dairy delivery in Washington DC at the time.

When President William Howard Taft’s cow Mooly Wooly died in 1909, it was replaced by Pauline Wayne, a 1500-pound Holstein-Friesian. She was a gift to the Taft family from the farm of Senator Isaac Stephenson of Wisconsin.

The 4-year-old black and white bovine was the last presidential cow, but by far the most famous. The media appears to have been obsessed with her. Her arrival was covered by The New York Times, and her exploits appeared in publications from The Evening Independent in St. Petersburg, Florida, to The Milwaukee Sentinel.

One particular bit of drama was covered far and wide. Pauline was visiting the International Dairymen’s Exposition in Milwaukee in 1911 (with her milk sold in souvenir bottles for 50 cents each). But on the trip home, she went missing.

We always figured it would be hard to lose a cow, especially the President’s cow. But it happened.

It turned out Pauline’s private car was accidentally hooked up to a train carrying cows to slaughter at the Chicago stockyards. Can you imagine the scandal?!

Luckily, after a series of frantic telegraphs from the dairy show, train attendants ended up locating Pauline’s car as newspapers reported how she “narrowly escaped death.” – WTF fun facts
