Prenatal maternal speech influences newborns' perception of speech sounds.
At this moment, the genetic makeup is complete, including the sex of the baby. In contrast, the mitochondrial DNA of the zygote comes entirely from the egg cell. Further cellular division is accompanied by the formation of a small cavity between the cells. [9] The growth rate of an embryo and infant can be reflected as the weight per gestational age, and is often given as the weight put in relation to what would be expected by the gestational age. The head is usually positioned down into the pelvis by now. Lecaneut, J. P., and Granier-Deferre, C. (1993).

Toxins include fetal exposure to lead, mercury, and ethanol or hazardous environments. More exact measurements can be performed with obstetric ultrasonography. In developed countries and at facilities where expert neonatal care is available, it is considered from 22 completed weeks (usually about 154 days) of gestation (the time when birth weight is normally 500 g) to 7 completed days after birth. It is here that lysis of the zona pellucida occurs. Nicotine results in less blood flow to the fetus because it constricts the blood vessels.

The term "conception" refers variably to either fertilization or to formation of the conceptus after its implantation in the uterus, and this terminology is controversial.
Both of these populations of lymphocytes have short-lived and long-lived groups.
Since the precursors of all the major organs are created by this time, the fetal period is described both by organ and by a list of changes by weeks of gestational age. Your baby is considered at 'term' when he is 37 weeks. [20] Such ideas are further reinforced by the fact that newborns present a preference for their mother's voice,[21] present behavioral recognition of stories only heard during gestation,[22] and (in monolingual mothers) present preference for their native language. The baby weighs about 10 ounces and is a little more than 6 inches long. The first sperm cell to successfully penetrate the egg cell donates its genetic material (DNA) to combine with the DNA of the egg cell resulting in a new organism called the zygote. 14, 220–224.
