Hello doctor, thank you for your response.
Yesterday, after my husband took a shower, I checked again and the small lump below his left testicle has disappeared.
I'm not sure why this happened.
I felt it after sexual intercourse.
My husband said that the testicles relax after intercourse, which is why I could feel it.
After showering, the testicles contracted, so I couldn't feel it anymore.
I'm very anxious.
Please help me with this.
Thank you.

Based on your description, it seems more like an epididymis issue, so you shouldn't worry too much.
If you still can't put your mind at ease, consider scheduling a visit to a urology clinic to confirm that everything is fine.
Wishing you health and safety from the Urology Department of Tainan Hospital, Department of Health!

When it comes to understanding testicular changes after sexual activity, it’s essential to recognize that the male reproductive system can exhibit various responses to sexual arousal and activity. The concerns you have regarding the changes in your husband's testicles, particularly the small lump you felt, are quite common, and I’d like to provide some insights to help alleviate your worries.

Firstly, it’s important to understand that the testicles can change in size and firmness due to several factors, including temperature, arousal, and even physical activity. During sexual arousal, the testicles may hang lower and feel more relaxed, which can make them easier to palpate. Conversely, after ejaculation or during a cooler environment, the testicles may retract and feel firmer or tighter, making any small lumps or changes less noticeable.

The lump you described could have been a normal anatomical structure, such as the epididymis, which is a coiled tube located at the back of each testicle that stores and matures sperm. Sometimes, the epididymis can feel more prominent or even slightly swollen after sexual activity due to increased blood flow and fluid accumulation. This is typically harmless and resolves on its own.

However, if the lump was indeed a new or unusual finding, it’s crucial to monitor it. Here are a few key points to consider:
1. Transient Changes: Many changes in the testicles can be transient and related to sexual activity. If the lump reappears or changes in size or consistency, it may warrant further investigation.

2. Pain or Discomfort: If your husband experiences any pain, discomfort, or additional symptoms such as swelling, redness, or changes in urination, it would be advisable to consult a healthcare professional. These could be signs of conditions such as epididymitis or other infections.

3. Self-Examination: Encourage your husband to perform regular self-examinations of his testicles. This can help him become familiar with what is normal for him, making it easier to identify any changes. He should feel for any lumps, swelling, or changes in size or texture.

4. Consultation with a Specialist: If there are any persistent concerns or if the lump returns, it would be wise to consult a urologist. They can perform a physical examination and may recommend an ultrasound if necessary to rule out any serious conditions such as a cyst, varicocele, or even testicular cancer.

5. Emotional Support: It’s understandable to feel anxious about changes in the body, especially when it involves intimate areas. Open communication between partners can help alleviate fears and encourage proactive health measures.

In conclusion, while it’s common for testicular size and firmness to change after sexual activity, any new or unusual lumps should be monitored closely. If there are any concerns, especially if accompanied by other symptoms, seeking medical advice is always the best course of action. Regular check-ups and open discussions about sexual health can significantly contribute to overall well-being.
