Do Men Really Only Like Thin Girls?
What kind of female figure meets the expectations of men? The answer might be "not fat to the eye, but with some meat to the touch!" Research shows that most men do not find overly thin women more attractive. Instead, they prefer women with a bit of full figured (body fat around 30%), with an hourglass figure—less fat around the waist and more around the hips and thighs (and preferably with natural large breasts). This means these women have a higher Body Mass Index (BMI) and a smaller waist-to-hip ratio. But what do these two characteristics communicate?

You know what? Do men have more sexual partners or women have more sexual partners
According to a study by the US government, the average number of sexual partners for men is seven, while for women it is four. A study by British scholars claims that men have an average of 12.7 female sexual partners in their lifetime, while women have 6.5 male sexual partners. Meanwhile, a Durex survey reveals that men in Hong Kong average 14.2 female partners, while women average just 4.1 male partners. In mainland China, men average 3.5 female partners, while women average 2.3 male partners. It seems that men everywhere have a reputation for being fickle and promiscuous. But wait a minute—doesn’t something seem off here? Sexual partnerships should be one-to-one. Since the male and female populations in every country are roughly equal, the following equation should hold true:

Is there such a thing? Can cycling mess with your pecker!
Every year, the Tour de France captures the imagination of many, with its high-tech carbon fiber bikes, sleek cycling gear, shiny helmets, and the iconic yellow jersey. The wind-like speed of the cyclists and the champagne and beautiful women waiting at the finish line are the envy of many. However, behind the glamour lies a less-discussed reality. Remember Lance Armstrong, the Tour de France champion who had a testicle removed? It makes one wonder if there's a connection between cycling and such health issues. Many male cyclists have experienced numbness in their genitals after long rides... In fact, the damage cycling can do goes beyond just feeling numb. Let's delve into the complex relationship between cycling and male health.

Can a Mouse Cable Fit Into the Urethra?
Recently, a news story has been making people uneasy: a young man was discovered by a female internet friend's boyfriend during a rendezvous. The boyfriend and his accomplices then forced a 1.2-meter-long mouse cable into the young man's urethra and up into his bladder. Everyone is astonished by the cruelty of the act—just how heartless does one have to be to insert such a long and thick cable into someone's urethra? In fact, urethral or bladder foreign bodies are not uncommon in urological surgery, and there are many objects more bizarre than a mouse cable that have been found.

When Life Gives Men Lemons: The Unbearable Agony of Testicular Pain
Throughout evolution, the distribution of nerves in our bodies has continually changed, yet the reproductive system, particularly the testicles, has always maintained a high density of nerve endings. This may be because the testicles are responsible for extremely delicate and crucial work, requiring exceptional sensitivity. This sensitivity extends not only to temperature, humidity, and movement but also to blood pressure and mechanical forces.

Hey man, have you ever tweaked your nuts?
Attentive gentlemen might have noticed that sometimes their testicles hang low, while at other times they seem to be pulled upward, closer to the body. This movement is particularly noticeable when the inner thigh is tapped or subjected to a sharp stimulus, causing the testicle on that side to rise or contract towards the body. This phenomenon is known as the cremasteric reflex.

Does your friendly neighborhood snake prefer to go straight or take the scenic route?From Da Vinci to MRI
Why study whether male erection is' straight 'or' curved '? It all starts with a human sketch by Leonardo da Vinci from 1493. This sketch is unique in medical history as it depicts the moment of intercourse. In it, the erect male penis appears almost straight, from the external part to the internal root. This anatomical hypothesis was seen as a perfect example of human mechanics during the Renaissance. However, modern science has turned this sketch into a "Rashomon" of sexual medicine.
