Effects of corpus luteum removal on progesterone, estradiol-17 beta and LH in early pregnancy of the tammar wallaby, Macropus eugenii



Effects of corpus luteum removal on progesterone, estradiol-17 beta and LH in early pregnancy of the tammar wallaby, Macropus eugenii



Journal of Reproduction and Fertility 83(1): 185-191



The quiescent corpus luteum of female tammars was reactivated by removal of the pouch young (RPY). The reactivated corpus luteum was ablated 3 days after RPY. Plasma progesterone and oestradiol concentrations were measured by radioimmunoassay in these and in sham-operated controls. Excision of the CL abolished the rise in progesterone seen at Day 5-6 in the sham-operated animals (130.7 +/- 56.6 vs 452.4 +/- 176.0 pg/ml, mean +/- s.d.). By contrast, oestradiol-17 beta values increased within 6-16 h of CL excision to 16.3 +/- 6.9 pg/ml and remained high for 1-3 days while in the sham-operated animals there were less sustained and more variable peaks of 10-20 pg/ml between Days 3 and 5 (mean 12.0 +/- 3.6 pg/ml at Day 4-5). We conclude that the early transient increase in peripheral plasma of progesterone is of luteal origin but the source of the oestradiol remains unknown.
