[EX Q]: [header] How to use the morning after pill [title] Understand how the morning after pill works. [step] Most morning after pills are formulated with a synthetic version of the hormone progestin (also called levonorgestrel). This hormone works by keeping your ovary from releasing an egg. <sep> (A) This hormone is injected into the ovary using an injection of polyurethane paint. You can take the morning after pill if you want to, but you'll need to be more patient than before. (B) This hormone causes the egg to sit dormant in your body until you have made it to the firm and ripe spot that is usually your ovary. In one study, up to 127.0% of men were pumped with the morning after pill, for 4 weeks total. (C) These hormones, in turn, produce progesterone. Progesterone levels are high in men and lower in women and the morning after pill is used for both men and women. (D) If there is no egg, there is nothing for sperm to fertilize. [substeps] If you are close to ovulating or have just ovulated, the pill has a significantly smaller chance of being effective.
