Horses are pristine animals, with an undoubtedly beautiful aesthetic. Due to their both loveable and personal characters, they are one of the most popular domesticated animals, with over 10 million domesticated horses in the U.S alone. If you have ever seen a horse up close, there are probably many physical features that catch your eye. One of the most unique is the large size of male horse’s willys. In today’s article, we are going to explain exactly why horses have big willys. 

Why do horses have big willys?

The reason horses have big willys (big penises) is quite simple. Female horses have extremely deep vaginas, with a width of 6-8 inches, and a length that can reach up to 30 inches. In order for a male horse to impregnate a female horse, their sperm must reach the female’s uterus. The sperm must reach the uterus in order to fertilize the egg, which can be very deep inside their vagina. Therefore, a male horse must have a very long penis in order for their sperm to reach the proper destination. If horses had smaller penises, it would be very hard for them to impregnate a horse. Over millions of years, horses evolved to having bigger and bigger penises, because horses with larger penises had a better chance of impregnating female horses. 

A common misconception about horses having long penises is that they have long penises just because they are big animals. While bigger animals do tend to have longer penises, this is not always the case. For example, despite reaching a body weight of 350 pounds, the average male gorilla has a penis that is 2 inches in length. There are a lot more factors involved in the size of specie’s penis, such as flexibility, whether the animal lives on land or in water, and the climate the animal lives in.
