Prokineticin 1 and leukemia inhibitory factor mRNA expression in the endometrium of women with idiopathic recurrent pregnancy loss.

Objective: To determine the expression patterns of prokineticin 1 (PROK1) and leukemia inhibitory factor (LIF) mRNA differ in peri-implantation endometrial tissue of women with idiopathic recurrent pregnancy loss (RPL) from normal fertile women.

Design: A case-control study.

Setting: University-based tertiary care center.
