“…Direct correlations between embryo diameter and respiration rate have not been described in other studies. On the other hand, correlations between blastocyst stage and the corresponding oxygen consumption have been reported for in vivo bovine (Thompson et al 1995) and in vitro porcine embryos (Sturmey & Leese 2003). In these studies, measurements of both early and expanded blastocysts confirmed that oxygen consumption decreased after the blastocyst had completed expansion.…”

“…However, the question as to the source of lipid has yet to be answered. It is unlikely, with perhaps the exception of the rabbit embryo, that mammalian embryos require endogenous stores of energy substrates and obtain their energy requirements by uptake of substrates from their surrounding environment [18,19]. It is most likely that the source of lipid accumulated in serum-exposed embryos is from the serum itself.…”

“…As oxygen is consumed, dissociation of oxyhemoglobin causes an increase in absorption a t 435 nm. Thompson et al (1995) have reported a novel noninvasive fluorescent technique for measuring oxygen consumption.…”

“…In our view, this technique has been seriously underutilized for obtaining information on embryo metabolism and viability. However, a recent report of a novel, noninvasive fluorescence method for measuring oxygen consumption of blastocysts should help to stimulate renewed interest in using respirometry (Thompson et al, 1995).…”
