Ultrasonographic measurements of ovary diameter and endometrial thickness in cynomolgus monkeys. (A) Ovary diameter after superovulation procedures at oocyte recovery. The length of the ovary was defined as the longest axis (straight blue line), while the width was measured perpendicular to the length at its widest point (dotted blue line). (B) The endometrial thickness of recipients at embryo transfer. The measurement was taken at the thickest part of the endometrium, typically in the transverse plane of the uterus (straight orange line). All measurements were taken using a digital caliper in ultrasound device software with an accuracy of ±0.01 mm. The scale bar is 5.0 mm.
