Pregnancy is the period through which an embryo is gestated and develops, this period of time is approximately 9 months in humans, in animals, there is a very rich variety of times in which the fetus develops. Pregnancy begins to elapse from the moment the sperm fertilizes the egg, the sperm is donated by the man or male and the egg is provided by the woman. During pregnancy, a series of interactions between the nutrients provided by the mother and the fetus are included, all kinds of mechanisms are developed in order to give the baby shape and safety.
The development of the embryo is established as time passes, through the period of pregnancy the woman or female cannot become pregnant again. The woman or female that she carries with her presents morphological changes, which go according to the growth of the fetus.Human pregnancy can last up to forty months to be considered normal, however, there are cases in which the expulsion of the child occurs in advance, in this case at week 25 a premature pregnancy can be considered.
Pregnancy represents a complex symptom in the female, in the case of humans, the absence of the menstrual period is the most common characteristic to identify a pregnancy, the studies that are carried out to verify that it is a pregnancy are basically with fluids such as urine or fluids expelled by the woman through the vagina, since the arrival of a baby to the breast belly represents an important change in the body's chemistry.
Culturally, pregnancy represents a diverse range of customs that go hand in hand with regional and local traditions. It is important to highlight that the conception of a baby is always governed by the rules established within a family nucleus. The most evolved cultures prohibit the conception of children between relatives, so that relationships can only be between people whose consanguinity is not the same, otherwise it could be considered from a nefarious act to an aberration.
