Effect of vitamin D status on clinical pregnancy rates following in vitro fertilization.

ABSTRACT:

Background

Recent studies suggest that vitamin D may play a role in human reproduction. Our goal was to investigate whether vitamin D levels are predictive of implantation and clinical pregnancy rates in infertile women following in vitro fertilization (IVF).

Methods

We prospectively evaluated vitamin D status, as determined by serum 25-hydroxy-vitamin D (25[OH]D) levels, in a cohort of 173 women undergoing IVF at Mount Sinai Hospital, Toronto, Ontario. Serum 25(OH)D samples were collected within 1 week before oocyte retrieval. We classified patients as having sufficient (≥ 75 nmol/L) or insufficient (or deficient; hereafter referred to as "insufficient"; < 75 nmol/L) serum levels of 25(OH)D. We compared patient demographics and IVF cycle parameters between groups. The prima
