borborygmus
Rhonchi are rumbling sounds generated by thick secretions in the lungs.
Gastrointestinal or gastroenteric
Borborygmus is an 11-letter medical term ending with "us." It means the rumbling noises made by intestines.
The sounds of the Heart, lungs, circulatory and gastrointestinal systems are heard using the amplified stethoscope. It makes it easier for a medical professional to hear the sounds that are produced by these systems in the body.

The technical term is boborgymus, but in all of my experience, I have never heard that term used. In practice everyone uses the term "bowel sounds." (Bor-bor-rig-mus; plural borborygmi). This same condition, although to a lesser degree, also occurs in your colon (large intestine) and may be accentuated before a bowel movement.

That is the medical term.
The medical term for hormone produced by the testis is testosterone. This is a hormone that is produced by males and is responsible for various functions in males.
Gas problems triggered by gastrointestinal disease may be harder to diagnose, and will typically require additional medical testing such as colonoscopy, barium enema, or an upper and/or lower gastrointestinal (GI) series.
