Testicular Size: When to Seek Medical Advice

What is the impact of testicular size?

Hello, Dr.
Hsu.
It seems that my testicles are smaller than those of my peers.
Sometimes, the left one feels like it’s almost disappearing, although it still looks small from the outside.
However, when I touch it, it feels different.
My friends say that size isn’t an issue, but rather function is what matters, and as long as the function is normal, it should be fine.
If I refrain from masturbation for a few weeks, the left testicle seems to get a bit larger.
Should I seek medical attention for this?

Hello, it is recommended to check semen analysis, male hormones, and sexual function.
If all results are normal, then size is certainly not an issue.
If there are any unclear points, feel free to ask again for further discussion and research.

When it comes to concerns about testicular size and health, it is important to approach the situation with both awareness and caution. Testicular size can vary significantly among individuals, and while some may feel that their testicles are smaller than average, this does not necessarily indicate a medical issue. However, there are several factors to consider when determining whether to seek medical advice.

Firstly, it is essential to understand what is considered a normal range for testicular size. Testicles typically measure between 3 to 5 centimeters in length and 2 to 3 centimeters in width. Variations are common, and many factors, including genetics, hormonal levels, and overall health, can influence size. If you feel that your testicles are significantly smaller than this range, or if you notice a change in size, it may warrant further investigation.

You mentioned that your left testicle sometimes feels as if it is "almost gone," which could be a cause for concern. While it is not uncommon for one testicle to be slightly larger or hang lower than the other, any significant change in size, shape, or sensation should be evaluated by a healthcare professional. This is particularly true if you experience discomfort, pain, or any other unusual symptoms.

Regarding the observation that your left testicle seems to increase in size after a period of abstinence from ejaculation, this could be related to various physiological factors. Testicles can temporarily swell due to increased blood flow or hormonal changes, but this should not be a consistent or dramatic change. If you notice that this fluctuation is significant or accompanied by pain or discomfort, it is advisable to consult a doctor.

In terms of functionality, as your friends mentioned, the primary concern is often whether the testicles are functioning properly, which includes hormone production and sperm production. If you have no issues with libido, erections, or fertility, this may provide some reassurance. However, it is still important to monitor any changes in size or sensation.

If you are experiencing anxiety about your testicular size or any associated symptoms, it is always best to err on the side of caution and seek medical advice. A healthcare provider can perform a physical examination, discuss your concerns in detail, and may recommend an ultrasound or other imaging studies if necessary. This can help rule out any underlying conditions such as testicular atrophy, varicocele, or other issues that could affect testicular health.

In summary, while variations in testicular size are normal, any significant changes or concerns about size, especially if accompanied by discomfort or other symptoms, should prompt a visit to a healthcare professional. It is better to address these concerns early on to ensure your reproductive health and peace of mind. Remember, your health is paramount, and seeking advice from a qualified medical professional is always a wise decision.
