Church & Dwight has launched the at-home First Response Digital Ovulation Test, which detects a woman’s personal luteinizing hormone (LH) surge based on her individual baseline hormone levels. The First Response Digital Ovulation Test provides 20 test sticks to detect the two most fertile days during a woman’s cycle. Daily testing starts on Day 5 of a woman’s period to begin determination of her personal baseline and ultimately allow detection of her LH surge. The LH surge is present 24–36 hours before ovulation, and indicates the optimal time to try to conceive.
