These hormones prevent ovulation and make it difficult for sperm to reach the egg, therefore reducing the chances of pregnancy. The molecular formula and weight of Levonorgestrel is CyuHy0 with a weight of 3124, while the molecular formula and weight of Ethinyl Estradiol is CyuHnO with a weight of 296.4.*
