. Tubular paired
accessory glands
are formed as diverticula of
the vasa deferentia. Sometimes the vasa deferentia themselves are glandular and fulfil the
functions of accessory glands. The paired vasa deferentia unite where they lead into the
ectodermally derived
ejaculatory duct
(the tube that transports the semen or the sperm to the
gonopore).
Accessory glands are 1-3 pair, either mesodermal of ectodermal in origin and associated
with vasa deferentia or ejaculatory duct. Its function is to produce seminal fluid and
spermatophores (sperm containing capsule).
