Hi,
Thanks for the query.
Have you noticed loosened testis of late? Do you have any swelling in the scrotum (testis area)? This can only be confirmed with a urological examination, and if there is a problem it could be fixed. It could be related to your scrotal skin or it could even be your psychological perception.
Scrotal skin is loosely attached in many individuals and is not a disorder as such. Get it confirmed by consulting a urologist.
