Fetuses The characteristic of “Man, from a biological, none other than reproduction. From the choice of partner for the birth of the child, retrace all the steps that the human body through.
Seduction First leg of our journey: the attraction between the sexes. The voice is a secondary sexual characteristic that plays a role in the seduction of another. Above, a unique image! The scanner allows for a true recovery of the vocal cords and lungs in the background.
Body Under the effect of caresses, the brain sends more blood to the skin surface. The camera records the heat waves of heat emitted by the body, which vary depending on their temperature. It can highlight an increase of 3 degrees of heat to the surface of the skin.
Partner Kisses and love we are feeling the effect of a drug. Taking cocaine active indeed the same brain areas.
Bisou Scientists have discovered the existence of taste receptors and taste buds on the inner surfaces of the lips.
Fertilization This amazing image was produced at the electron microscope, one technique to restore volume in the two sex cells of the human body: the egg and sperm.
Meeting The oocyte measures about 100 microns, the thickness of a hair-and microscopic sperm, which seeks to force a passage that does 3.
Marathon Even under favorable conditions (ovulation) intercourse does balance that once out of four “babies”. Must still reach a sperm to fertilize an egg.
Life Fourth week, the outline of the heart. Three weeks after fertilization, the heart beats!
Development It is called an embryo until the eighth or tenth week of pregnancy. In addition, we are talking about fetuses. In this picture we can clearly see the fetal limb and its vasculature.
Eye Located on the side of the head, the eyes move toward the front of the face gradually with the development of the head. They are still sealed.
Gender At 12 weeks, sexual differentiation occurs. Before it is impossible to say whether the mother is expecting a boy or a girl.

Penis In boys, the penis is formed, followed 2 weeks later by the glans and foreskin.
First parent-child In the fifth month the fetus takes real facial expressions. Thanks to advances in 3D ultrasound, the fetal facial expressions become observable.
Ultrasound Because of the quality of these three-dimensional images, some parents will find similarities with members of their families.
Mimicry In the womb, the fetus is already beginning to enjoy some grimaces and other facial expressions.
Smile Although he began to smile or grimace in utero, it will take some time to understand your baby and absorb all our facial expressions.

By regurgitating this chemical cocktail, the fetus activates macrophages mother contained in amniotic fluid. These macrophages then penetrate into the uterine wall, his trigger inflammation and early contractions.
Technology The pictures obtained by 3D ultrasound are very accurate, as seen in this comparison with the face of a newborn child.
