Cervicectomy with uterovaginal anastomosis in the rhesus monkey: a new surgical model for reproductive studies

Cervicectomy with uterovaginal anastomosis in the rhesus monkey allows easy and non-traumatic access to the uterine cavity through the vagina for such purposes as biopsy, flushing, aspiration of fluid, and placement of IUDs. Endometrial and tissue samples cannot be contaminated by cervical mucus. The surgical procedure and results on eleven animals are described. Neither uterine nor ovarian function appeared to be significantly altered. The surgical model seems well suited to long-term studies on IUDs.
