To improve fertility, sexual intercourse is best timed when the cervical mucus is at it’s most receptive to sperm. This is usually 1-3 days before ovulation actually occurs. Research studies have shown that women who have intercourse around the time the fertile mucus is noted, get pregnancy quicker (Scarpa 2007).
Other research tells us that the fertile period is up to six days and ends on the day of Ovulation (Wilcox 1995). Having intercourse after ovulation does not result in pregnancy. This is because the progesterone hormone produced following ovulation, prevents sperm getting into the cervical mucus by making it thick and therefore hostile to sperm.
Having intercourse infrequently i.e. 2 or less times a week is associated with a lower chance of pregnancy. Whilst it is known that ejaculating several times can reduce the sperm count present per ejaculation, research studies do not reveal this to reduce the chance of pregnancy. As such, having intercourse every day or every other day leading up to ovulation is likely to give you the best outcome.
