Knowledge is completely lacking concerning the endocrine physiology of reproduction in marine turtles. A preliminary hormone forcing experiment utilizing immature Chelonia mydas at Mariculture, Ltd., Grand Cayman Island, B.W.I., is described. Gonadotropin from pregnant mare's serum induced marked hypertrophy of testicular and epididymal tissue while sheep luteinizing hormone had no apparent effect on those organs A crude homogenate prepared from sea turtle pituitaries may have caused limited testicular activity. Testosterone‐propionate and Estradiol‐dipropionate treatment groups showed striking development of primary and secondary sexual characteristics. The histology of the testis related to the various treatment groups is also discussed.
