Vitamin D improves in-vitro fertilization outcomes in infertile women with polycystic ovary syndrome and insulin resistance

Abstract

Our data indicate that vitamin D supplementation can help return serum vitamin D levels in infertile women with PCOS and IR to normal levels leading to an improvement in the quality of embryos and a significantly higher clinical pregnancy rate. Maintaining a normal serum vitamin D level in PCOS women is very important in achieving a successful clinical pregnancy following in-vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI).
