Thanks for your question. A person’s testicles are typically about the same size. However, some people may notice that one testicle is slightly bigger than the other testicle. As both testicles grow during puberty the difference can sometimes become more noticeable. Even during puberty this difference in size should be small.
Sometimes one testicle can feel larger than the other testicle because there is something else going on. Some causes include:
- Varicocele: This is a dilated blood vessel by a testicle.
- Hydrocele: It is a collection of fluid around a testicle.
- Hernia: A hernia is a weakness in the abdominal wall that lets some of the abdominal contents extend into your scrotum.
Whenever you have a concern about testicular size or texture, it is always a good idea to talk to your health care provider. They will ask you questions to help figure out the cause. They will also likely do a testicular exam.
