Prolog’s Vitamin D3 product is designed for the couple having difficulty conceiving, undergoing fertility treatments by inseminations or IVF, with unexplained infertility, or recurrent pregnancy loss.
Vitamin D3, cholecalciferol, is a steroid hormone synthesized by the skin that regulates blood calcium levels as well as cell growth and differentiation. With respect to fertility, vitamin D receptors and vitamin D metabolizing enzymes are found in reproductive tissues of women and men. Vitamin D insufficiency is a common condition and has been associated with decreased embryo implantation potential, increased miscarriage risks and various problems in pregnancy. In men, inadequate Vitamin D has been related to sperm motility problems.
Vitamin D may play various roles in human reproduction and several recently published studies indicate that vitamin D levels are predictive of implantation and ongoing pregnancy rates in in vitro fertilization (IVF).
