Do Horses Have 3 Genders?
No, horses do not have three genders. Horses, like most mammals, are a dioecious species, meaning they have two distinct biological sexes: male and female. The perceived “third gender” often referred to in equestrian circles stems from the role of castration, specifically the creation of geldings. While geldings are male horses, they differ from stallions due to their inability to reproduce and often exhibit altered behavior. This difference in reproductive capability and behavior can be misinterpreted as a third gender, but it’s important to understand that geldings are still biologically male.
Understanding Sex and Gender in Horses
It’s crucial to differentiate between biological sex and social constructs of gender, although in horses, the concept of ‘gender’ is primarily linked to their role and management by humans. Sex refers to the biological characteristics that define male and female individuals, primarily based on chromosomes and reproductive organs. In horses, this is straightforward: a horse is either born with male reproductive organs (testicles) and XY chromosomes, or female reproductive organs (ovaries) and XX chromosomes.
The term “gender,” while more nuanced in human societies, often encompasses social roles and behaviors. In the context of horses, terms like “stallion,” “mare,” and “gelding” describe specific categories based on sex and reproductive status, influencing their roles within human management.
Stallions: The Mature Males
A stallion is an uncastrated male horse that is typically four years old or older. Stallions possess the capability to reproduce and exhibit characteristic behaviors associated with their high testosterone levels. These behaviors can include increased aggression, a strong drive to breed, and the marking of territory. Stallions used specifically for breeding are sometimes referred to as “studs.” Historically, stallions were used as riding horses, too.
Mares: The Mature Females
A mare is a female horse that is typically four years old or older. Mares are capable of reproduction and experience estrous cycles (heat cycles) during which they are receptive to breeding. Mares play a vital role in horse breeding programs. In the past, mares were kept for breeding purposes only.
Geldings: The Castrated Males
A gelding is a male horse that has been castrated, meaning his testicles have been surgically removed. This procedure eliminates the production of testosterone, which significantly alters the horse’s behavior. Geldings are generally more docile, easier to handle, and less prone to aggressive behaviors compared to stallions. Geldings cannot reproduce and are commonly used for riding, driving, and other disciplines where a calmer temperament is desirable.
The Misconception of a “Third Gender”
The term “third gender” is sometimes used informally when discussing geldings because their castration leads to distinct behavioral and physiological differences compared to stallions. Geldings do not exhibit typical stallion behaviors related to mating or competition for mates. They are often managed differently and interact differently with other horses. However, it is vital to reiterate that geldings remain biologically male. Their physical sex is not altered by castration, only their hormonal profile and reproductive capability. The absence of the testes, however, does not create a third biological sex.
Importance of Accurate Terminology
Using accurate terminology is crucial when discussing horse gender and reproductive status. Misusing the term “gender” can lead to confusion and misunderstanding. Sticking to terms like “stallion,” “mare,” and “gelding” to accurately describe the horse’s sex and reproductive status fosters clear communication and understanding.

Frequently Asked Questions (FAQs)
1. What is a colt?
A colt is a male horse under the age of four. After turning four, if not castrated, a colt becomes a stallion.
2. What is a filly?
A filly is a female horse under the age of four. After turning four, a filly becomes a mare.
3. Can a gelding still exhibit stallion-like behavior?
Yes, occasionally. While castration significantly reduces testosterone levels, some geldings may still display some stallion-like behaviors, such as mounting or aggression. This is often referred to as being a “false rig“.
4. Can a male horse have babies?
No. Only mares (female horses) can have babies. Stallions fertilize the egg, but they do not carry the foal. Geldings cannot reproduce at all.
5. Why are male horses gelded?
Male horses are gelded to reduce aggressive behavior, make them easier to handle, and prevent unwanted breeding. Geldings are generally more suitable for riding and other activities.
6. Is it possible for a mare to become infertile?
Yes. Mares can become infertile due to various reasons, including age, uterine infections, hormonal imbalances, and physical injuries.
7. What is a yearling?
A yearling is a horse, of either sex, between one and two years old.
8. Can a colt impregnate a mare?
Yes, a colt can impregnate a mare, even as young as a yearling or two-year-old. It is essential to keep young colts separated from mares to prevent unwanted pregnancies.
9. What is a group of horses called?
A group of horses is commonly called a herd. Other terms, such as “team” or “harras,” may be used in specific contexts.
10. Are intersex horses common?
Intersexuality in horses is rare. Diagnosis is challenging as there are often no specific changes visible in the reproductive tract.
11. How many times can a stallion mate in a day?
The number of times a stallion can mate in a day varies depending on his age, health, and fertility. Some stallions can breed up to three times a day, while others may need more rest between sessions.
12. What is the gestation period of a mare?
The gestation period of a mare is approximately 326 to 354 days. Gestation can be as long as 375 days. The longest gestation period was over 400 days!
13. Will a pregnant mare accept a stallion?
Typically, a pregnant mare will refuse the advances of a stallion. However, this is not always a guaranteed indicator of pregnancy.
14. Do horses remember their foals?
Research suggests that horses form strong memories of their foals and can recognize them even after long periods of separation.
15. Can close breeding (e.g., father-daughter) be beneficial?
Close breeding, such as mating a sire with his daughter, is used on an experimental basis to test for undesirable recessive genes. This practice is not common due to the risk of amplifying negative traits. GamesLearningSociety.org offers resources on animal behavior which touches on some related fields of horse behavior.
