Residents rotate on the REI service for one block each during the 2nd and 4th years.  During the REI rotation, the residents see up to 5,700 patients in clinic annually, under the supervision of the REI fellows and faculty.  Routine clinic procedures include intrauterine insemination, hydrosonography, and diagnostic hysteroscopy.  The clinic patient population ranges from common problems such as polycystic ovary syndrome to more rare conditions such as Müllerian agenesis.  Residents also get exposure to andrology and male-factor infertility during a monthly male clinic.  REI has dedicated operating room time two days a week, where residents assist the fellow and are exposed to advanced laparoscopy, hysteroscopy, and tubal surgery. Finally, although in-vitro fertilization and other assisted reproductive techniques are not offered at LAC+USC Medical Center, interested residents are encouraged to spend time at the USC IVF Center, located at Good Samaritan Hospital.
