Cockroaches show sexual dimorphism. There are several differences between the two sexes.
Phallomeres are the external genitalia of the male cockroach.
Gonopore is the opening of the ejaculatory duct of the male cockroach.
Spermatophore - The sperms produced from testes, while the male 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.
Ovarioles are found in the female cockroach. Ovarioles are egg-producing tubules that are the fundamental units of ovaries in female insects.
