In male cockroaches, in the 9th sternum of the abdomen, a pair of small, un-jointed anal styles and in the 10th tergum of the abdomen, a pair of long, palp-like jointed anal cerci are present.
The male reproductive system of cockroach consists of a pair of testes. The testes lie on each lateral side in the 4th – 6th abdominal segments. Male gonapophysis or phallomeres represent the external genitalia. These are made up of chitin. They are asymmetrical structures and surround the male gonopore. The sperms are stored in the seminal vesicles. The sperms are glued together in the form of bundles called spermatophores. Spermatophores are discharged during copulation.
