If you or someone you love has undergone an orchidectomy (the surgical removal of a testicle) due to injury, cancer, or a medical condition, a flood of questions usually follows. Chief among them: “Am I still fertile?” The short answer is a resounding yes. A man with one testicle can father a child naturally. However, there are subtle distinctions in how the body adapts and what to look out for.
Let’s dive into the science, the research, and the reality of living with “one testicle.”
How One Testicle Does the Work of Two
The human body is remarkably redundant. Just as you can live a perfectly healthy life with one kidney or one lung, the male reproductive system is designed with a “backup plan” too.
When one testicle is removed, the remaining one often undergoes compensatory hypertrophy. This means that the remaining testicle grows slightly larger and increases its production to meet the body’s demands for both testosterone and sperm.
Below is how one testicle works
1. Sperm Production (The Numbers Game)
To conceive, you don’t actually need millions of sperm from two sources; you only need one healthy sperm to meet a healthy egg. A single healthy testicle typically produces enough sperm for natural conception. While the total sperm count might be slightly lower than if you had two, it usually remains well within the “fertile” range.
2. Testosterone Levels
The testicles are also responsible for producing testosterone, the hormone that drives libido and erectile function. Research shows that one testicle is generally sufficient to maintain healthy male hormone levels, ensuring that your sex drive and ability to perform remain unchanged.

What Does the Research Say About One Testicle?
Clinical studies have consistently shown high success rates for men with a single testicle.
- Testicular Cancer Survivors: A landmark study published in the Journal of Clinical Oncology followed men who had one testicle removed due to cancer. It found that the majority of those who attempted to conceive were successful, provided they didn’t undergo intensive chemotherapy or radiation that damaged the remaining “good” testicle.
- Paternity Rates: Research indicates that the paternity rate for men with one testicle is nearly identical to that of men with two, assuming the remaining testicle is healthy, and the partner has no fertility issues.
- The “Compensation” Effect: A study in Fertility and Sterility noted that in many cases, the remaining testicle increases its sperm output to about 70% to 80% of what two testicles would normally produce; more than enough for a successful pregnancy.
Common Concerns & Obstacles for a man with one testicle
While the outlook is positive, there are a few scenarios where fertility might require a bit more attention:
1) The Health of the “remaining” Testicle
If the reason for losing one testicle was a systemic issue (like an undescended testicle from birth or a genetic condition), the remaining testicle might also have underlying functional issues.
2) Treatments Like Chemo or Radiation
If a testicle is removed due to cancer, the surgery itself rarely causes infertility. However, follow-up treatments like chemotherapy can temporarily or permanently slow down sperm production in the remaining testicle.
3) Psychological Impact
Fertility is as much about the mind as it is the body. The stress or “performance anxiety” following an injury or surgery can sometimes lead to erectile dysfunction or a lower libido. It’s important to remember that these are often psychological rather than physical.
Tips for Boosting Fertility for a Man with One Testicle
If you are planning to start a family, here are a few ways to ensure your “remaining testicle” is in peak condition:
- Get a Semen Analysis: This is a simple test that checks your sperm count, shape, and movement. It provides peace of mind and a baseline for your fertility.
- Lifestyle Choices: Avoid smoking, excessive alcohol, and “heat” (like hot tubs or tight underwear), which can lower sperm quality.
- Supplementation: Vitamins like Zinc, Selenium, and Vitamin C are known to support sperm health.
- Protect Your Asset: If you play contact sports, always wear a cup. With only one testicle left, protecting it is non-negotiable!
Conclusion: Can a Man with One Testicle Father a Child?
Losing a testicle can feel like a blow to one’s masculinity or plans, but the biological reality is much more optimistic. A single, healthy testicle is a powerhouse. If you are concerned, the best first step is a conversation with a urologist. They can perform a quick check-up to ensure your hormone levels and sperm quality are where they need to be.
You are still a man, still fertile, and the dream of fatherhood remains very much alive.
