Timed Intercourse for Couples Trying to Conceive

Timed intercourse using urine ovulation tests appears to improve live birth and pregnancy rates in women under 40 compared to intercourse without ovulation prediction. Level of evidence: "B"

The certainty of the evidence is downgraded for risk of bias (commercial funding).

Summary

Cochrane review[Abstract]1 included 7 studies with a total of 2464 women or couples. Compared to intercourse without ovulation prediction, urinary ovulation detection increased the chance of live birth (RR 1.36, 95% CI1.02 to 1.81, 1 RCT, n=844). This suggests that if the chance of a live birth without urine ovulation prediction is 16%, the chance of a live birth with urine ovulation prediction is 16% to 28%.
