What is a Gelding Horse, and Why Are They Used in Polo?
Horses have been used by mankind for centuries for various activities such as work, transport and sports. Among the many equestrian disciplines that exist, polo stands out for its dynamism, speed and connection between rider and horse. In this context, geldings play a fundamental role. But what is a gelding and why is it preferred in polo? Below, we will explore this topic in detail.

What is a gelding horse?
A gelding horse, also known as a castrated horse, is a male horse that has had its testicles surgically removed. This procedure, known as castration, is intended to modify certain natural behaviors of the animal that may be problematic under certain circumstances. Castration is a common practice in the management of horses, especially those intended for sporting or recreational activities.
Castration is usually performed on young horses between 6 months and 2 years of age, although it can also be performed on older horses when circumstances warrant. Choosing the ideal time to castrate depends on factors such as the horse's physical maturity, temperament, and the owner's goals. Castration not only reduces testosterone levels, but also decreases aggressive or dominant behaviors that can arise in intact (uncastrated) horses. These behaviors include territorial marking, inappropriate mounting, and aggression toward other horses or even people.
In addition, castration makes daily handling and living with other horses easier. Geldings are generally calmer and less likely to get involved in fights or conflicts within stables. This not only improves their quality of life, but also reduces the risk of injury for both them and the horses they share space with. Another important benefit is that, because they are easier to handle, geldings are often better suited to intensive training and competitive environments, such as polo.
Although castration is a relatively simple surgical procedure, it should be performed by an experienced veterinarian under sterile conditions to minimize risks such as infection or postoperative complications. Recovery is generally rapid, and in most cases, horses can resume normal activities within a few weeks.
Benefits of Castrated Horses
- More stable temperament: Geldings tend to be less temperamental and aggressive than intact horses. This makes them ideal for team sports such as polo, where it is essential for the horse to remain calm under pressure.
- Ease of handling: Castration reduces behaviours such as marking, mounting and other instinctive impulses that can be problematic in a competitive environment. This allows riders and handlers to work more safely and effectively.
- Better coexistence: In stables and during training, geldings can coexist more harmoniously with other horses, as the reduction in testosterone minimises conflicts between them.
Why are gelding horses used in polo?
Polo is a sport that requires agile, fast and easy-to-handle horses. Every detail counts in the performance of the team, and the temperament of the horse is a key factor. Geldings have become the preferred choice for this sport for several reasons:
1. Control and obedience
Polo involves quick changes of direction, sudden accelerations and decelerations, as well as a high level of concentration on the part of both rider and horse. Geldings, having a more even temperament, are more responsive to the rider's commands and less prone to distractions or unpredictable behavior.
2. Durability and endurance
The intense nature of polo requires horses that can maintain consistent performance without becoming easily exhausted. Although castration does not directly affect the horse's physical ability, a calmer temperament can translate into more efficient use of energy during matches.
3. Team safety
A horse with aggressive or unpredictable behaviors can put both other horses and players at risk. Geldings, being calmer and more manageable, reduce this risk and contribute to a safer environment on the court.
The horse selection process for polo
Not all horses are suited for polo. Breeders and trainers look for certain physical and temperament characteristics when selecting horses. Some of the factors considered include:
- Suitable physique: Horses used in polo are usually agile, of medium size and with well-developed musculature.
- Personality: Geldings that display a calm but energetic disposition are ideal for this sport.
- Training: Horses must be trained from a young age to adapt to the demands of polo. This includes becoming familiar with the constant contact of the ball, the stick and other horses on the field.
The impact of geldings on modern polo
In modern polo, geldings have raised the level of competition by offering greater control and consistency in play. Elite teams around the world rely on geldings to ensure the best possible performance in matches.
Moreover, this practice benefits not only the players, but also the horses themselves. Being easier to handle and less prone to stress, geldings often enjoy better living conditions both on and off the pitch.
Myths and facts about geldings
Despite the benefits, there are some myths surrounding geldings. Some believe that castration diminishes their physical performance or their mood, but the reality is that this depends more on the training and care they receive. With proper nutrition, a structured training program, and regular veterinary care, geldings can reach their full potential without problems.
Conclusion
A gelding horse is an indispensable ally in the world of polo. Thanks to their balanced temperament, ease of handling and willingness to work as a team, these specimens have become the preferred choice for breeders and players alike. Understanding what a gelding horse is and how it impacts their role in polo not only enriches our knowledge of the sport, but also highlights the importance of responsible and ethical animal management.
The use of geldings in polo is a clear example of how human intervention can optimize the relationship between horse and rider, ensuring the best possible performance in one of the most demanding equestrian disciplines in the world.
