Fig.1: Ampulla of the male reproductive system.

Explanation of Solution

The expanded distal region of the ductus deferens is called ampulla. This region acts as a storage chamber for the semen for several months and the sperm remains temporarily dormant with low metabolic rates during this time. The ampulla also connects the ducts from seminal vesicles and forms the ejaculatory ducts.
