Why Testicles Hang Low: Is It Normal?

Why are the testicles droopy?

When my boyfriend is aroused, his penis is hard, but his testicles hang quite low.
The room has air conditioning, so it's not hot.
Why is his penis hard but his testicles are very low? He has a scar about 4 centimeters long near his pubic hair, which he says is from a surgery for a hernia he had as a child.
When I asked him why his testicles hang low, he said he has always been like that and doesn't know why.
My only question is, is it normal for the penis to be hard while the testicles hang low? Is there something wrong? Could it affect fertility?

Normalcy does not necessarily correlate with infertility.

More Info

It’s completely normal for testicles to hang lower than the penis, and this is a common anatomical feature in many males. The position of the testicles can vary significantly from person to person due to several factors, including temperature, genetics, and individual anatomy.
The primary function of the testicles is to produce sperm and hormones, particularly testosterone. They are located in the scrotum, which is the pouch of skin that hangs outside the body. This external positioning is crucial because sperm production requires a temperature that is slightly lower than the normal body temperature. The scrotum helps regulate this temperature by contracting or relaxing in response to heat or cold. When it’s warm, the scrotum relaxes, allowing the testicles to hang lower; when it’s cold, the scrotum contracts, pulling the testicles closer to the body for warmth.

In your boyfriend's case, the fact that his testicles hang lower while his penis is erect is not indicative of any dysfunction or problem. It’s a normal anatomical variation. The presence of a surgical scar from a previous hernia repair does not typically affect the position of the testicles or their function, unless there were complications from the surgery that impacted the surrounding structures.
Regarding fertility, the position of the testicles alone does not determine fertility. Fertility in males is influenced by several factors, including sperm count, sperm motility, and overall reproductive health. If your boyfriend has had no issues with fertility in the past, and if he has regular erections and ejaculations, it is unlikely that the position of his testicles would affect his ability to conceive.

If there are concerns about fertility or any changes in sexual function, it would be advisable for him to consult a healthcare provider. A urologist can perform a thorough evaluation, including a physical examination and possibly a semen analysis, to assess reproductive health.
In summary, the position of the testicles hanging lower than the penis is normal and does not indicate any underlying health issues. As long as there are no other symptoms such as pain, swelling, or changes in sexual function, there is generally no cause for concern. If you or your boyfriend have any lingering worries, seeking professional medical advice can provide reassurance and clarity.
