The question of when life begins has been discussed for years and remains a subject on which members of society have opposing views. Probably never be possible to reach agreement on this issue ", British doctors said in their report, prepared for a possible legal reform in that country. Although there is no absolute answer, the scientific literature does provide some clues on these issues:
* When can you survive?
* When does the brain work?
* Do you have pain?
* How do you define the moral status of the fetus?
When can you survive?
Last year, Amillia, an American girl, born after 22 weeks in the womb and only 284 grams. This is an exceptional case, but the truth is that in recent times the limit of viability (ie, the threshold from which a newborn can survive in circumstances acceptable) has decreased dramatically. Fetal viability is not only a threshold changing over time, but it still depends on the individual case.
When does the brain work?
Unlike animals, human brain development is much slower and continues to form during childhood. However, towards the end of the second trimester of pregnancy begins to show some activity.
have seen that fetuses in the third quarter and have some ability to 'learn', ie to get used certain stimuli and even to respond to short-term memory. Thus, a study in fetuses of 35-36 weeks was that when repeatedly applied a vibration to the belly of the mother, and not as much as startled at the first opportunity. After 24 hours, seemed to recognize the sound. "Interpret there exists consciousness as we understand it is very difficult."
you in pain?
is considered that the fetus can feel pain from 26 weeks of gestation. At least in that time has the necessary circuitry to sense and produce a similar biochemical reactions to what we consider pain. However, just as we do not know how another person perceives the pain, we can not know how you feel a fetus.
Although you can not know for sure if once 'deployed circuit' the fetus actually feels pain, the scientific community has opted for "a principle of prudence." That is, when performing operations on the fetus prenatal given a cocktail of drugs that do not move, does not alter the heart rate and, if anything, does not suffer.
How do you define the moral status of the fetus?
Although science can give clues about the different stages of embryonic development, does not give a final answer to a multifaceted character issue.
Many people have difficulty in pointing out a stage where they believe the fetus achieves moral status and does not believe that lack of such consideration up to a certain stage of development, from which deserves full protection.
You can see in this gorgeous graphics as the embryo is formed in each of the stages of pregnancy and check the progress of their sensitivity over development in the womb.
