Summary

The lay summary the sponsor registered on ClinicalTrials.gov.

The purpose of this study is to determine whether progesterone hormone levels differ following egg retrieval with a single lumen needle compared with a double lumen needle. These levels will be measured on several days before and after egg retrieval. The progesterone levels in each IVF group will also be compared to the group of women who are having IUI. In addition, these progesterone levels will be correlated with pregnancy outcomes.
