News | Can Urine Ovulation Tests Improve Pregnancy Rates? Timing the Fertile Window May Matter More
A new systematic review found that using urine tests to identify ovulation and timing intercourse during the fertile window may improve the chance of natural conception. The study, led by Dr. Tatjana Gibbons of the Nuffield Department of Women's and Reproductive Health at the University of Oxford, was presented at the 38th annual meeting of the European Society of Human Reproduction and Embryology (ESHRE).
The study was based on an updated analysis from the Cochrane database and included 6 studies involving a total of 2,374 women trying to conceive naturally.
Couples who used urine ovulation tests to identify ovulation had a higher chance of pregnancy than those who did not intentionally time intercourse. Pregnancy rates ranged from 20% to 28% among couples who used urine testing, compared with 18% among those who did not time intercourse.
"This updated study is the first to clearly show that using urine ovulation monitors to identify ovulation may improve the likelihood of conception," Dr. Gibbons said.
However, there is still insufficient evidence for other home-based or clinical methods of ovulation monitoring, such as fertility awareness-based methods (FABM). FABM includes calendar predictions, observing changes in cervical mucus, and wearing devices that measure physiological indicators such as body temperature. Although these methods are widely used in women's health apps, their scientific validity requires further evaluation.
The research team noted that there are not enough data to confirm whether FABM significantly improves pregnancy or live birth rates. The FABM analysis included only 2 studies and 160 women, and the quality of evidence was low.
Further analysis found that urine-based ovulation monitoring was more effective for couples who had been trying to conceive for less than 12 months, but its effect among couples with difficulty conceiving after more than 12 months remains unclear.
The study also examined possible adverse effects of scheduled intercourse on quality of life and stress, such as psychological pressure or sexual tension caused by reduced spontaneity. However, evidence for assessing these effects remains very limited.
As health apps and wearable devices become more common, more women use mobile apps to predict ovulation and time intercourse. Dr. Gibbons said that although timed conception may appear more efficient, additional high-quality research is needed to balance its potential psychological burden against its clinical benefits.
She specifically cautioned, "Doctors cannot broadly recommend this approach until we can evaluate its effects in different groups, such as people with unexplained infertility."
