No change in sexual activity during preconceptional multivitamin supplementation.
OBJECTIVE: To study sexual activity related to preconceptional multivitamin supplementation. DESIGN: 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. SETTING: The Hungarian randomised double blind controlled trial of periconceptional multivitamin supplementation. PARTICIPANTS: 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. CONCLUSION: Multivitamins do not increase sexual activity.
