title: The effect of preconceptional multivitamin supplementation on fertility.
abstract: A significantly higher rate of conceptions occurred after preconceptional multivitamin supplementation in comparison with a placebo-like trace element supplementation in the Hungarian randomised, double-blind, controlled trial. This difference was explained by 5% shorter time in the achievement of conception.
