Is endometrial thickness associated with fertility outcomes in intrauterine insemination? a cohort study.

ABSTRACT:

Background

Intrauterine insemination (IUI) is the first line treatment for conditions such as unexplained or mild male factor infertility. Endometrial thickness (EMT) is an important indicator for predicting pregnancy outcomes in in-vitro fertilization. However, published data about whether EMT has a predictive capacity for success in IUI is controversial, and most studies suggest that endometrial thickness is not associated with IUI success, which limits its use in IUI.

Methods

This was a single center retrospective cohort study that included women undergoing IUI cycles from January 2007 to June 2021. We categorized EMT into thin (<7 mm), medium (7-14 mm), and thick (>14 mm) groups. For all IUI cycles, we computed adjusted odds ratios (aORs) and 95% confidence interv
