The male reproductive system in cockroaches consist of a pair of testes, a pair of vas deferens, ejaculatory duct, seminal vesicle, mushroom glands, and external genitalia. Testes are present at$4^{\mathrm{t}\mathrm{h}}\mathrm{ }–\mathrm{ }{6}^{\mathrm{t}\mathrm{h}}$segments while the mushroom gland is present in$6^{\mathrm{t}\mathrm{h}}\mathrm{ }–\mathrm{ }{7}^{\mathrm{t}\mathrm{h}}$segments. The female reproductive system consists of a pair of ovaries, a pair of oviducts, a common oviduct i.e. vagina, genital chamber and external genitalia. The genital chamber shows the opening of spermathecae which is a storehouse of sperms. Ovaries extend from$2^{\mathrm{n}\mathrm{d}}\mathrm{ }–\mathrm{ }{6}^{\mathrm{t}\mathrm{h}}$segments and show many tubules known as ovarioles. Spermathecae is in the$6^{\mathrm{t}\mathrm{h}}$segment.
