Is It Normal for One Testicle to Be Larger and Lower? - Urology

More Info

It is not uncommon for one testicle to be slightly larger or positioned lower than the other. In fact, it is quite normal for men to have some degree of asymmetry in their testicles. The left testicle is often found to hang lower than the right in many individuals, although this can vary from person to person.
However, there are several factors to consider when assessing whether the size difference and positioning of your testicles are normal or if they warrant further investigation. Here are some points to keep in mind:
1. Normal Anatomy: The testicles are not always symmetrical. Variations in size and position can be due to normal anatomical differences. As long as there are no accompanying symptoms such as pain, swelling, or the presence of lumps, a slight difference in size or position is usually not a cause for concern.

2. Hydrocele: One possible explanation for a larger testicle could be a hydrocele, which is a fluid-filled sac surrounding a testicle. This condition can cause swelling and may make one testicle appear larger. Hydroceles are generally benign and may resolve on their own, but if they persist or cause discomfort, medical evaluation may be necessary.

3. Varicocele: Another condition to consider is a varicocele, which is an enlargement of the veins within the scrotum. This can lead to a feeling of heaviness and may cause one testicle to appear larger. Varicoceles are more common on the left side but can occur on either side.

4. Testicular Torsion: Although you mentioned that you do not feel any obvious lumps, it is important to be aware of testicular torsion, a medical emergency where the spermatic cord becomes twisted, cutting off blood supply to the testicle. This condition usually presents with sudden severe pain and swelling, and immediate medical attention is required.

5. Tumors: While you have not felt any lumps, it is crucial to remain vigilant. Testicular tumors can sometimes present as a change in size or shape of the testicle. Regular self-examinations can help you monitor any changes over time.

6. Self-Examination: It is advisable to perform regular self-examinations of your testicles. This involves gently rolling each testicle between your fingers to feel for any lumps or abnormalities. If you notice any changes, such as a new lump, persistent swelling, or pain, you should consult a healthcare provider.

7. Consultation with a Healthcare Provider: If you are concerned about the size difference or if you experience any discomfort, it is best to consult a healthcare provider. They can perform a physical examination and may recommend an ultrasound or other imaging studies to rule out any underlying conditions.

In summary, while a slight difference in size and position of the testicles can be normal, it is essential to remain aware of any changes and to seek medical advice if you have concerns. Regular self-examinations and consultations with a healthcare provider can help ensure your testicular health is maintained.
