How do ovulation tests work?

Most people do not realise that there are only a few days in a woman's cycle when making love can result in conception - and only 2 days when it is most likely. So achieving the goal of pregnancy can just be a matter of better timing.

Clearblue Ovulation Tests can increase your chances of becoming pregnant by reliably indicating the 2 days of your cycle when you are most likely to conceive - the days closest to when the egg is released from the ovary. This process is called ovulation. Making love during these 2 days gives you your best chance of conceiving.

Ovulation is triggered by the sudden release of the hormone lutenising hormone (LH) from the pituitary gland situated close to the brain. This surge in LH occurs approximately 24 to 36 hours before ovulation.

Used each day, on the days around the time when the LH surge is expected, Clearblue Ovulation Tests identify the 2 days in your cycle when you are most likely to conceive.
