The time schedule of masculinization showed sequent appearances of the vas deferens, external sex character, androgenic gland, and testis. The androgenic gland cells of undeveloped rough surfaced endoplasmic reticula seemed to be unfunctional, indicating their negative role in sex differentiation of the genital organ.}, pages = {87--94}, title = {Differentiation of Genital Organs and Androgenic Gland in the Kuruma Prawn Penaeus japonicus}, volume = {41}, year = {1992} }
