Ultrasound-guided follicular aspiration in squirrel monkeys.
The objective of this study was to test whether ultrasound-guided oocyte retrieval is an effective mechanism for collecting oocytes in squirrel monkeys. Although ultrasound-guided follicular aspiration has been described in Old World primates, oocyte retrieval in New World primates is typically performed via laparoscopy or laparotomy. However, these procedures, especially the first, can be invasive. Ultrasound has been used for pregnancy monitoring in multiple species of primates including Saimiri spp. Transabdominal ultrasound as a diagnostic tool is non-invasive. Transabdominal ultrasound was utilized to visualize ovarian follicles during aspiration under light anesthesia. This procedure resulted in collection of a total of 29 oocytes from six animals with minimal post-procedural pain. Manipulated animals were returned to the social group the same day.
