Androgenic gland

Japanese: 造雄腺 - ぞうゆうせん(英語表記)androgenic gland
Androgenic gland
Also called the male gonad. A string-like glandular endocrine tissue attached to part of the internal reproductive organs of animals belonging to the subclass Malacostraca. It is found in males in dioecious species and in male phases in hermaphroditic species. In most cases, it consists of several cells attached to the walls of the vas deferens or seminal vesicles, and in some isopods, it is attached to the tip of the testis. The androgenic gland was first described in a type of crab, but H. Charniaux-Cotton (1954) revealed its physiological function in the giant sand dollar and gave it this name.
