Conglobate (phallic) Gland: It is a large elongate sac like structure lies beneath the mushroom gland and ejaculatory duct. It opens by the side of male gonopore.

Answer 2

Function of phallic gland in male cockroach

Explanation:

• The male reproductive system of Periplaneta consists of a pair of testes, a pair of vasa deferentia, an ejaculatory duct, a pair of seminal vesicles, a mushroom-shaped gland and a phallic gland.

• A thin duct called vasa deferens begins from the posterior end of each testis.
• The two vasa deferentia run backward and open into a wide median duct, the ductus ejaculatorius in the seventh segment.
• The ejaculatory duct is a muscular tube that extends posteriorly and opens at the gonopore or the male genital pore.
• A phallic or the conglobate gland is also associated with the male reproductive system of the Periplaneta. The duct of this gland opens near the gonopore. Its function is still not known.
