Aedeagus of Pentodon idiota Photomicrograph of the aedeagus of water scavenger beetle Tormissus linsi (from above). An aedeagus (/ i ˈ d i. ə. ɡ ə s / or / i. d i ˈ eɪ. ɡ ə s / [1] [2] pl. aedeagi) is a reproductive organ of male arthropods through which they secrete sperm from the testes during copulation with a female.
Male genitalia of Lepidoptera. The main component of the male reproductive system is the testicle, suspended in the body cavity by tracheae and the fat body.The more primitive apterygote insects have a single testis, and in some lepidopterans the two maturing testes are secondarily fused into one structure during the later stages of larval development, although the ducts leading from them ...
The genitalia are attached onto the tenth or most distal segment of the abdomen. Lepidoptera have some of the most complex genital structures in the insect groups with a wide variety of complex spines, setae, scales and tufts in males, claspers of different shapes and different modifications of the ductus bursae in females.

The spine-covered penis of Callosobruchus analis, a bean weevil. Harvestmen are the only male arachnids that have a penis. In male insects, the structure analogous to a penis is known as an aedeagus. The male copulatory organ of various lower invertebrate animals is often called the cirrus. [32]
A notable example of a bird with a pseudo-penis is the red-billed buffalo weaver, which do not use their pseudo-penis for direct insertion during copulation; however it does play a part in successful mating and stimulation. [15] Similarly to the red-billed buffalo weaver, the cassowary, a ratite, exhibits a pseudo-penis in both males and females.
Like Entognatha, Archaeognatha and Zygentoma, the spiracles on the abdomen do not have closing muscles. [11] [12] Uniquely among insects, mayflies possess paired genitalia, with the male having two aedeagi (penis-like organs) and the female two gonopores (sexual openings). [1] [4]

The male bed bug aedeagus has been shown to carry five (human) pathogenic microbes, and the exoskeleton of female bed bugs nine, including Penicillium chrysogenum, Staphylococcus saprophyticus, Stenotrophomonas maltophilia, Bacillus licheniformis, and Micrococcus luteus. Tests with blood agar have shown some of these species can survive in vivo ...
