Oxygen consumption of human endometrium during the menstrual cycle measured in vitro using an oxygen electrode

Oxygen consumption of human endometrial tissue was measured in vitro in air and high oxygen gas phases using an oxygen electrode. The oxygen consumption increased throughout the proliferative phase, peaking around ovulation and then decreasing during the secretory phase. This pattern persisted whether the oxygen consumption was expressed on a dry weight, DNA or protein basis. Storage of the tissue and mincing produced lower values of oxygen consumption.
