Solution Edos and you can Post was indeed measured playing with Estradiol EIA Kit (Cayman Chemicals, MI) and you may androstenedione chemical immunoassay package (Oxford Biomedical Look Inc., MI), correspondingly. ELISAs out-of T and E1 was did depending on the same means of 17,20?-P (Matsuyama mais aussi al., 1998b) and you will explained lower than temporarily.
