Check when you're next ovulating

Knowing when you or your partner ovulates will help you time intercourse to increase your chance of conception. As sperm can live at their healthiest inside a woman for two to five days, you’re more likely to conceive when you have intercourse on, or around one to two days before ovulation.

Genea Hollywood’s Ovulation Tracking service is more reliable. Unlike store bought trackers, we test patients’ blood to measure multiple hormone levels, which is a more accurate form of predicting ovulation than a simple “positive” level of a single hormone in urine.

Ovulation normally occurs 24 to 36 hours after the luteinizing hormone (LH) surge is detected, so identifying this LH surge helps determine when you are about to ovulate. Sperm can remain active for up to five days, so couples can conceive by having intercourse prior to the egg being released.

Nurses closely watch for the LH surge and as soon as there is a sign of an increase, we advise couples to have intercourse.

Store bought kits may notify women as to when they are ovulating, but intercourse ahead of ovulation is key.
Downloadable apps are very popular for tracking cycles and are useful for keeping cycle records. However they rely on simple mathematical formulas to suggest the time of ovulation, but this might not be accurate for an individual woman.
