“…Although recent studies in this species indicate that LH-RH administration can stimulate an ovulatory release of LH (Amoss, Blackwell & Guillemin, 1972;Kanematsu, Scaramuzzi, Hilliard & Sawyer, 1974;Dufy-Barbe, Franchimont, Dufy & Vincent, 1975), the effects that ovarian hormones have upon this response are unclear.
