For now, one well-timed intrauterine insemination is the way to go

Abstract

Two articles on pregnancy rates from superovulation and IUI in relation to the IUI protocol were reviewed. Results from a meta-analysis of IUI number (one vs. two) and from a randomized trial of IUI timing (33 hours vs. 39 hours after hCG administration) suggest that one well-timed insemination within several hours of ovulation represents a reasonable balance between efficacy and cost.
