How often should a couple go to business for the equation 1 + 1 = 3 to work out? There is no strict key nor beat for the dance of conception, but there certainly is a recommendation from fertility experts.
Within the fertility window, there should be intercourse once a day. If more frequently, sperm quality could be affected. By the way, the time of day is irrelevant, but at least 20 hours should have passed between ejaculations. But don’t put any extra pressure on yourself and don’t get too tense or go about the business as if on an assembly line. Daily sex within the fertile window is a recommendation. You may and should allow yourself to ‘dance’ as much as you wish, even if ‘the show’ only happens once on the day of ovulation. After all, you are the conductors.
