उत्तर
Ampulla
Explanation:
Ampulla is not a male accessory gland; it is part of the male reproductive duct system where the vas deferens enlarges to store and transport sperm. The true male accessory glands are seminal vesicles, prostate, and bulbourethral glands, which produce and secrete fluids that form semen and support sperm function.
