Let's be real for a second. If you’re searching for how to say testicles in Spanish, you aren't just looking for a dictionary definition. You’re likely trying to navigate a doctor’s visit, a biology class, or maybe just a very awkward conversation with a friend. Spanish is a massive language, spanning over 20 countries, and the word you use in a Madrid hospital might get you a blank stare or a laugh in a Mexico City street market.
Language is weird like that.
The literal, clinical, and most "correct" translation for testicles in Spanish is testículos. It’s a cognate, meaning it looks and sounds almost exactly like the English version. Easy, right? But nobody actually says testículos unless they’re wearing a white lab coat or reading from a textbook. In the real world, the language of anatomy is messy, regional, and deeply tied to culture.
The Formal Side of Things: Using Testículos Correctly
If you find yourself in a medical setting, stick to the basics. Los testículos is the gold standard. It’s professional. It’s clear. It avoids any risk of offending someone or sounding like you’ve spent too much time watching gritty Spanish soap operas.

Spanish-speaking doctors, particularly those following guidelines from the Royal Spanish Academy (RAE), will always default to this. When discussing health issues like testicular torsion (torsión testicular) or cancer (cáncer de testículo), accuracy saves lives. There is no room for slang when you're describing symptoms to a urologist.
Interestingly, the word shares its root with the word "testify." In ancient Roman tradition—though some historians argue this might be more of a linguistic myth than a legal reality—it was said that men would hold their testicles when swearing an oath. Whether that’s 100% historically accurate or just a "factoid" that survived the centuries, it highlights how central this part of the anatomy has been to the concept of "witnessing" or "truth" in Western languages.
Beyond the Textbook: Common Slang and Regionalisms
Honestly, if you use testículos in a bar in Buenos Aires, people are going to think you’re a bit stiff.
The most common, everyday term across most of the Spanish-speaking world is huevos. Yes, literally "eggs." It’s ubiquitous. You’ll hear it in Mexico, Colombia, Spain, and throughout the Caribbean. While it’s technically slang, it’s so common that it’s almost become the default informal word. However, be careful. Using huevos is vulgar in many contexts. It’s the equivalent of saying "balls" in English. It’s fine with your buddies, but maybe don't say it to your father-in-law.
In Spain, you might hear cojones. This is a heavy-hitter. It’s used not just to describe the anatomy, but as a linguistic Swiss Army knife.

- ¡Qué cojones! (What the hell/What nerve!)
- Tiene cojones. (He's got guts.)
- Me importa un cojón. (I don't give a damn.)
But wait, it gets more specific. In Chile, you’ll hear cocos. In other regions, you might encounter bolas. If you’re in Argentina, bolas is standard, but it’s also the root of one of their most famous insults: boludo. Originally, a boludo was someone with "big balls" (suggesting they moved slowly or were dim-witted), though today it’s used more like "idiot" or even "dude" depending on the tone.
Why the Vocabulary Matters for Your Health
Knowing how to say testicles in Spanish isn't just a linguistic curiosity; it’s a health necessity. According to the Testicular Cancer Foundation, this is the most common cancer in males ages 15 to 35. If you are living in a Spanish-speaking country or treating Spanish-speaking patients, being able to describe an "irregularidad" (irregularity) or a "bulto" (lump) is vital.
Men often avoid these conversations because of "machismo"—a cultural concept that can sometimes discourage men from showing vulnerability or seeking medical help. By knowing both the formal term testículos and the informal huevos, you can bridge the gap in communication. Sometimes, a patient might feel more comfortable using slang, and a provider who understands that slang can build better trust.
Common Symptoms to Describe in Spanish:
- Dolor: Pain.
- Inflamación: Swelling.
- Pesadez: Heaviness.
- Endurecimiento: Hardening.
If you’re experiencing any of these, you don’t need to be a linguist. You just need to get to a doctor and say, "Tengo un problema con mis testículos." They’ll take it from there.
The Cultural Weight of the Word
In Spanish culture, specifically in places like Mexico and Spain, the concept of the testicle is tied to bravery and "manliness." You see this in the phrases people use every day. To have "huevos" or "cojones" isn't just about anatomy; it's about courage.
This creates a weird paradox.
On one hand, the body part is hyper-masculinized in slang. On the other hand, it’s a topic of deep privacy and often shame when something goes wrong health-wise. This is why many health organizations in Latin America have launched campaigns using humor to break the ice. They use the slang—talking about "tus huevos"—to get men to actually perform self-exams. It’s a "meet them where they are" strategy. It works because it strips away the sterile, scary medical language and talks to men in the way they actually speak.
Translating the Nuance
If you’re translating a document or a story, don't just "find and replace."
Think about the character. A teenager in East L.A. speaking Spanglish is going to use different words than a grandfather in Seville. If you’re writing a script, "Watch out for your balls!" becomes "¡Cuidado con los huevos!" or "¡Cuidado con las bolas!" depending on the map.
If you are translating a medical brochure, stick to testículos. If you use huevos in a professional brochure, you’ll look like you used a cheap AI translator from 2022 that didn't understand tone.
Linguistic Variations at a Glance
Since Spanish is spoken by over 500 million people, the variations are endless. Here is a quick look at how the word shifts based on where you are:
- Neutral/Medical: Testículos (Used everywhere).
- Mexico/Central America: Huevos is king. You might also hear blanquillos (a "polite" way to say eggs/testicles in some households).
- Spain: Cojones is everywhere. Pelotas is also common.
- Argentina/Uruguay: Bolas is the standard slang.
- Chile: Cocos is very specific to this region.
Using the wrong one isn't the end of the world. People will generally understand you through context. If you’re at a doctor’s office pointing to your groin and saying "cocos," they’ll get the idea. But if you want to sound like a local, pay attention to what the people around you are saying.
Practical Steps for Moving Forward
If you are learning Spanish or preparing for a trip, don't just memorize the word. Understand the vibe.

- Stick to the formal: Use testículos in any situation where you aren't 100% sure of the social hierarchy. It is never "wrong," even if it’s a bit formal.
- Learn the local slang: If you're moving to a specific country, listen for how men talk about health. Do they say bolas? Huevos? Cojones?
- Perform self-exams: Regardless of what language you speak, check yourself. The medical term is autoexploración testicular.
- Watch for "False Friends": Don't confuse testículos with testigos (witnesses), though they share a root. Telling a judge you have two "testículos" when you mean you have two "testigos" will make for a very memorable day in court.
Spanish is a beautiful, rhythmic, and incredibly varied language. Whether you're navigating a medical issue or just trying to understand a joke in a Netflix series, knowing the difference between the clinical testículos and the gritty cojones gives you a deeper window into how the Spanish-speaking world views the body, masculinity, and health.
When in doubt, lead with respect. Most people will appreciate the effort to speak their language correctly, especially when it comes to sensitive health topics. Stick to the clinical terms for safety, but keep the slang in your back pocket so you aren't caught off guard by a colorful local expression.
