The male reproductive system of cockroach consists of a pair of testes, vasa deferentia, an ejaculatory duct, utricular gland, phallic gland and the external genitalia.
(i) Testes:
There is a pair of three-lobed testes lying dorsolaterally in the 4th and 5th abdominal segments, being embedded in the fat body. The testes are well developed and elaborate structures in young cockroach and they are full of sperms.
(ii) Vasa Deferentia:
From each testis arises a thin thread-like, white vasa deferens.
(iii) Ejaculatory Duct:
The ejaculatory duct is an elongated wide median duct which runs backwards in the abdomen and opens out by male gonopore situated ventral to the anus.
(iv) Utricular or Mushroom-shaped Gland:
It is a large accessory reproductive gland, whitish in colour and situated at the junction of vasa deferentia with the ejaculatory duct.
(v) Phallic or Conglobate Gland:
It is a long and club-shaped accessory gland. Its anterior broader end lies in the 6th segment slightly to the right of the nerve cord.
(vi) External Genitalia:
Some chitinous asymmetrical structures are found surrounding the male gonopore at the end of the abdomen. These are three phallomeres or male gonapophyses which constitute the external genitalia.
