Vertebrate reproduction depends on the function of 2 distinct gametes, sperm and eggs, which develop in 2 different organs, the testis and the ovary. Testes and ovaries are composed of germ cells, supporting cells and interstitial cells. In this review, we describe the origin and the fate of these cell lineages and how they interact with each other to form sexually dimorphic reproductive organs in medaka. We delineate how the temporally different association and establishment of these lineages contribute to a variety of seemingly different sex differentiation processes among teleost fish. Thus, teleosts represent an intriguing group in which to study the fundamental processes of gonadal development through comparing conserved and unique mechanisms.
