摘要：

Plasma concentrations of progesterone and oestradiol-17β were determined by radioimmunoassay procedures in the sexually mature female snapping turtle at four different stages of the annual ovarian cycle. The highest level of progesterone in the peripheral plasma was detected during the luteal stage (June), whereas the concentration of oestradiol was highest (280 pg/ml) in May, immediately before ovulation.
