Ovulation tests detect the rise in luteinizing hormone (LH) levels in urine. The increase in LH hormone precedes ovulation and triggers it within 24 - 48 hours. After ovulation, the egg can survive for only 24 hours or less, while sperm can survive for a few days within a healthy body. Ovulation tests can help predict the two most fertile days and increase the chances of pregnancy if intercourse occurs during these days.

These tests DO NOT require any other device to function. They are used as is and are one-step technology, resulting in a result produced in a very short time.
