What is the ampulla?
The ampulla of Vater is a small opening that enters into the first portion of the small intestine, known as the duodenum. The ampulla of Vater is the spot where the pancreatic and bile ducts release their secretions into the intestines.
What is the purpose of the ampulla?
The ampulla secretes a yellowish fluid, ergothioneine, a substance that reduces (removes oxygen from) chemical compounds, and the ampulla also secretes fructose, a sugar that nourishes the sperm.

What is difference between ampulla and papilla?
The major duodenal papilla (papilla of Vater) is the point where the dilated junction of the pancreatic duct and the bile duct (ampulla of Vater) enter the duodenum. The ampulla is surrounded by the sphincter of Oddi (SO), which controls the release of bile and pancreatic fluid into the duodenum.
What is the function of Ampulla in male reproductive system?
The ampullae act as storage chambers for the semen and contribute secretions to it. The yellow secretions of the ampullae include ergothioneine, a substance that reduces chemical compounds, and fructose, a sugar and nutrient. Both secretions moisten the sperm and help to keep them viable.
Does fertilization occur in Ampulla?
