Getting pregnant: three or more weekly relationships
To achieve a pregnancy as soon as possible we must know the concept of fertility . It is defined as the probability of getting a pregnancy during a single menstrual cycle. This fecundability is different for each species and, obviously, for each woman. Nowadays we are not able to determine previously that of each woman but we know that of the human species.
Human couples have a maximum fertility rate of 20 percent . That is, we can get a pregnancy in 20 percent of couples who have no problems and seek pregnancy in a woman’s menstrual cycle .
This fecundability rate is very low compared to other species. And it is something that must be taken into account to reduce the stress that the search of pregnancy in a couple implies, since in itself, the possibility of getting a pregnancy is very low in just one menstrual cycle.
