Effect of Cervical Occlusion During Intrauterine Insemination (IUI)
Study Hypothesis: There is a difference in pregnancy rates between intrauterine insemination (IUI) in cycles performed with cervical occlusion by a balloon catheter designed for sonohysterograms as compared to those performed with a standard inseminator.
The investigators will compare pregnancy rates in patients undergoing routine IUI either with balloon occlusion or with standard insemination. The patients will receive the standard clinical care per the investigators' office guidelines, except they will be randomized to insemination with either of two catheters.

Experimental: Cervical occulsion
Insemination Eliptosphere catheter filled with 1cc of air for 15 minutes. H/S Eliptosphere by Copper surgical (U.S. Patent No. 5,624,399)
Procedure: Intrauterine Insemination
The intervention arm will undergo temporary (15 minutes) cervical occlusion with the eliptosphere intracervical catheter. This catheter is typically used to perform saline infusion ultrasounds to image the uterine cavity in our practice.
Other Name: H/SH
Active Comparator: Standard IUI
Insemination with TOmcat catheter
Procedure: IUI with the standard inseminator
The control arm will undergo insemination with the standard inseminator (TOmcat catheter).
