Intrauterine oxygen tension during the oestrous cycle in the hamster: patterns of change
DL Kaufman, JA Mitchell - … Biochemistry and Physiology Part A: Physiology, 1994 - Elsevier
Oxygen tension (pO 2) within the uterine lumen of the hamster during the oestrous cycle was
measured in vivo with a polarographic oxygen sensor. Mean oxygen tension underwent
cyclic variation; maximum pO 2 occurred during dioestrus (35.2±1.9 mmHg). Minute-to-
minute alterations in pO 2 also occurred; the frequency of change in pO 2 was maximal
during early dioestrus (94.4±8.9 peaks/hr) and minimal during pro-oestrus (31.2±5.6
peaks/hr). The amplitude of change in pO 2 was maximal during late dioestrus (40.7±3.6 …
