1) Seminal vesicle : The sperms produced from testes, while the cockroach is still young, are brought by the vasa deferentia into the seminal vesicles for storage. The sperms in the seminal vesicles are glued together in the form of bundles called spermatophores.

(3) Collaterial Glands: There is a pair of white much branched collaterial glands, the left is much larger than the right. Both these glands continue as collaterial ducts which join to form a common duct which opens into the dorsal side of the genital chamber. These are the accessory reproductive glands.

(5) Spermathecae: These are a pair of club-shaped, unequal-sized, one spermathecae being larger than the other, structures. Both the spermathecae unite to form a short common duct which opens into the genital chamber on a small spermathecal papilla. Some workers claim that there is a single spermatheca and it has a lateral caecum.
