Ovulation Prediction Kits have become quite popular and can be quite useful to help you find your fertile time. Recently Advanced OPKs were also made available. Standard OPK. OPKs work by measuring the presence of Luteinizing Hormone (LH) in your urine.A surge of LH which is sent to your ovary causes your ovary to produce enzymes which in turn causes the dominant follicle to rupture and release the egg into the Fallopian tube.ecently Advanced OPKs were also made available.
