Fertility is the ability to conceive and give birth to a child. Many factors can affect fertility, including age, overall health, and lifestyle choices. If you’re concerned about your fertility, there are various ways to check it.
One of the most common ways to check fertility is to use an ovulation predictor kit (OPK). OPKs measure the levels of luteinizing hormone (LH) in your urine. LH is a hormone that surges just before ovulation, so an OPK can help you identify your most fertile days.
