During week 2 of the menstrual cycle (day 8 to day 14 or
ovulation), estrogen levels rise until it reaches its peak. Typically, days
12-14 have the highest levels of estrogen, which causes an increase in Luteinizing Hormone, which is responsible for the release of the egg cell. If
hormone levels fail to reach its peak before day 14, ovulation is not possible
because the egg cannot be released. Pregnancy may be highly unlikely.

Communication refers to a state when one animal conducts information to another animal making a certain type of modification in the animal, which acquires the information. Animals generally communicate using signals that may involve visual, auditory or sound based; chemicals involving pheromones, and others.
A pheromone refers to a discharged chemical signal used to stimulate a reaction in another individual of the similar species. Pheromones are generally common among social insects, like bees and ants. It is used to fascinate the opposite sex, mark a food trail, raise an alarm, or to stimulate other composite behaviors.
This kind of communication plays an essential role in natural selection. It helps in obtaining mates, establishing defending or dominance territory.
