1. Home ovulation tests

Assuming a couple does not have any obvious health issues that may affect their fertility, easy-to-use home ovulation kits, such as the Clearblue Digital Ovulation Test, can help to determine when a woman is at her most fertile. The tests work by detecting the body’s production of LH, which surges rapidly and peaks 24-36 hours before ovulation. 

Packs contain a number of testing strips, and a test should be done once daily, using the first urine after sleep, starting from between day five and day 20 of a woman’s cycle. The actual start day will depend on the individual’s known cycle length. All test instructions should be read carefully before use.

Some fertility tests also monitor oestrogen levels and can therefore indicate a wider fertility window of four days instead of just two. This is because levels of oestrogen rise a few days before ovulation. These are identified as days of “heightened” fertility, whereas the surge in LH that occurs just before ovulation is when a woman’s fertility is at its peak.

2. Home pregnancy tests

Home pregnancy tests are convenient, easy to use and can be used in the privacy of the home. They are also able to provide fast, accurate results – some as early as four days before a woman’s period is due. Examples of available tests include First Response Early Result and Clearblue Early Detection Pregnancy Test. 

All tests work on the same basic principle: by detecting levels of hCG. This is the hormone produced when a fertilised egg implants into the wall of the uterus. While it’s possible to detect hCG before a woman’s period is due, levels rise with each day of the pregnancy, so the later the test is taken, the more accurate it is. If a woman tests early and gets a negative result but still does not get her period, she may need to take a second test. Advise customers to read the instructions carefully and not to use tests past the expiry date. There is usually a helpline included with the test to call if they have any questions about the test or the result.

3. Other tests

Male fertility tests for home use are also available, which can help to identify whether men have a low sperm count. Examples include SpermCheck Fertility. If the results do indicate a low sperm count, individuals should be advised to speak to a pharmacist or GP for further investigation.
