The presence of a high concentration of progesterone (10\u22125m) during 5-h pulse culture significantly inhibited incorporation of substrate carbon from [U-14C]glucose into both the acid-soluble and acid-insoluble glycogen fractions, but had no effect on non-glycogen fractions. Catabolic utilization of glucose as estimated by the rate of carbon dioxide and lactate production was not affected by the presence of progesterone (10\u22127 to 10\u2212 5m), oestradiol (10\u221210 to 10\u22128m) or a combination of both. The results indicate that ovarian steroids at expected physiological concentrations do not directly influence embryonic energy metabolism.<\/jats:p>","DOI":"10.1530\/jrf.0.0790267","type":"journal-article","created":{"date-parts":[[2004,3,20]],"date-time":"2004-03-20T01:55:52Z","timestamp":1079747752000},"page":"267-273","update-policy":"https:\/\/doi.org\/10.1530\/rep\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":9,"title":["Effects of oestradiol and progesterone on the metabolism of [U-14C]glucose by mouse morulae and early blastocysts\n                    <i>in vitro<\/i>"],"prefix":"10.1093","volume":"79","author":[{"given":"N.
