火蚁 S. invicta Buren（膜翅目：蚁科）的雄性生殖系统由睾丸、传出血管、输精管、精囊、附属腺、射精管、楔子、阳囊和外生殖器组成。新封闭的雄性的睾丸表现为 4 个巨大的白色裂片，里面充满了精子。睾丸的每个叶仅包含 1 个卵泡。随着睾丸退化，成熟的精子通过传出血管和输精管迁移到精囊中。精囊附着在附属腺上，附属腺内衬有分泌性柱状上皮。辅助腺的后端逐渐变细并联合形成射精管。在辅助腺和射精管的交界处发现硬化的楔形物。阳茎膀胱连接楔形后方的射精管，内衬有厚重肌肉组织包裹的鳞状上皮。射精管向后延伸形成远端阳茎，由 3 对瓣膜包围，包括外生殖器。
The male reproductive system of the fire ant, S. invicta Buren (Hymenoptera: Formicidae), consists of the testes, vasa efferentia, vasa deferentia, seminal vesicles, accessory glands, ejaculatory duct, wedge, aedeagal bladder and external genitalia. The testes in newly eclosed males appear as 4 large white lobes filled with packets of sperm. Each lobe of the testes contains only 1 follicle. As the testes degenerate, the maturing sperm migrate through the vasa efferentia and vasa deferentia into the seminal vesicles. The seminal vesicles attach to the accessory glands, which are lined with secretory columnar epithelium. The posterior ends of the accessory glands taper and unite to form the ejaculatory duct. A sclerotized wedge is found at the junction of the accessory glands and the ejaculatory duct. An aedeagal bladder, joining the ejaculatory duct posterior to the wedge, is lined with squamous epithelium enveloped by heavy musculature. The ejaculatory duct continues posteriorly to form a distal aedeagus surrounded by 3 pairs of valves, comprising the external genitalia.
