What Are Ovulation Kits?
Ovulation kits, or ovulation predictor kits (OPKs), are tests women use to predict when they will ovulate. Females ovulate when the ovary, a female reproductive organ, releases an egg into the fallopian tubes. Typically, this occurs roughly two weeks into the average 28-day menstrual cycle. Many women, however, have very irregular cycles and do not fit this pattern. The days surrounding ovulation are the days in which women are fertile, or capable of becoming pregnant. For this reason, ovulation kits are often used by women wishing to become pregnant and sometimes by those wishing to avoid pregnancy. Ovulation kits estimate the time of a woman’s ovulation by monitoring the concentration of luteinizing hormone (LH) in her urine. LH is always present in the urine, but it increases in the 24 to 48 hours prior to ovulation. This increase causes an egg to drop from one of the ovaries, known as ovulation. If a woman is seeking to become pregnant, it is best to have sexual intercourse the day
