Is it bad to have minimal fluid in right scrotal sac?

The answer: no

Explanations:

The male scrotum contains two oval-shaped organs known as testicles. The testicles are located in a pouch of loose skin called the scrotum. It is normal to have a small amount of fluid in the scrotum. This fluid helps to protect the testicles. However, too much fluid in the scrotum can be a sign of a medical condition, such as hydrocele or inguinal hernia. If you are concerned about the amount of fluid in your scrotum, you should see a doctor.
