Analysis of follicular events in owl monkeys (Aotus azarai infulatus) using B-mode and Doppler ultrasound
Ultrasound (B-mode) was used to analyze follicular events in 12 trained female owl monkeys (Aotus azarai infulatus). The animals were examined every 48 hours for over 90 days to measure and map follicular growth in both ovaries and to measure (using Doppler velocimetry) local hemodynamic changes...

Ultrasound (B-mode) was used to analyze follicular events in 12 trained female owl
monkeys (Aotus azarai infulatus). The animals were examined every 48 hours for over
90 days to measure and map follicular growth in both ovaries and to measure (using
Doppler velocimetry) local hemodynamic changes during the peri-ovulatory stage. There
were 44 follicular growth events, each with two or three follicular waves, and a mean
SEM interval between events of 17 1.13 days. There were various hemodynamic changes
during follicular growth; both vascular resistance index and pulsatility index decreased
during the time when the follicle diameter peaked. Thus, both B-mode and Doppler
ultrasound were useful for monitoring ovarian follicular events in owl monkeys. |
