title: No change in sexual activity during preconceptional multivitamin supplementation.
abstract: OBJECTIVE
  To study sexual activity related to preconceptional multivitamin supplementation.
  
  
  METHODS
  The rate of sexual activity (weekly sexual intercourse number) was compared before and during multivitamin supplementation and between women with multivitamin and placebo-like trace element supplementation.
  
  
  METHODS
  The Hungarian randomised double blind controlled trial of periconceptional multivitamin supplementation.
  
  
  METHODS
  Six hundred and eighty-seven women with multivitamin and 655 women with trace element supplementation in the preconceptional period.
  
  
  RESULTS
  There was no difference in the rate of sexual activity between the multivitamin and the trace element groups.
