Associations Between Preconception Plasma Fatty Acids and Pregnancy Outcomes.

Background: Although fatty acids are involved in critical reproductive processes, the relationship between specific fatty acids and fertility is uncertain. We investigated the relationship between preconception plasma fatty acids and pregnancy outcomes.

Methods: We included 1,228 women attempting pregnancy with one to two previous pregnancy losses from the EAGeR trial (2007-2011).

Shorter Time to Pregnancy With Increasing Preconception Carotene Concentrations Among Women With 1-2 Previous Pregnancy Losses.

Although maternal nutrition may affect fecundity, associations between preconception micronutrient levels and time to pregnancy (TTP) have not been examined. We assessed the relationship between preconception fat-soluble micronutrient concentrations and TTP among women with 1-2 prior pregnancy losses. This was a prospective cohort study of 1,228 women set within the Effects of Aspirin in Gestation and Reproduction (EAGeR) Trial (United States, 2007-2011), which assessed the association of preconception-initiated daily low-dose aspirin with reproductive outcomes.

C-Reactive protein in relation to fecundability and anovulation among eumenorrheic women.

Objective: To assess systemic inflammation in relation to fecundability and anovulation.

Design: Prospective cohort study among participants in the Effects of Aspirin in Gestation and Reproduction trial who were assigned to the placebo.

Setting: Academic medical centers.
