Because of a link in blood supply between a mother and fetus, it has been found that stress can leave lasting effects on a developing fetus, even before a child is born. According to recent studies, these effects are mainly the result of two particular stress biomarkers circulating in the maternal blood supply: cortisol and catecholamines.
The cortisol levels will rise along with blood pressure. Increased blood pressure will have an effect on cerebral blood flow, cerebral blood flow velocity and intracranial pressure. Increased pressures and velocity can lead to intracranial hemorrhage. Prolonged exhalation may also cause some adverse effects.
These cortisol rhythmic changes occur throughout infancy and early childhood, along with changes in sleep patterns. [23] The activity of the HPA stress system adapts by repeated exposure to stressful stimulation. [25] As newborns progress through the early months of life, babies experience increased cortisol levels during medical examinations.
Cortisol has a permissive effect on the actions of hormones that increase glucose production, such as glucagon and adrenaline. [ 7 ] Cortisol also plays an important, but indirect, role in liver and muscle glycogenolysis (the breaking down of glycogen to glucose-1-phosphate and glucose) which occurs as a result of the action of glucagon and ...

Reed says the size of the baby and the uterus and the amount of amniotic fluid, which cushions the baby in the amniotic sac, can account for a larger or smaller bump, along with one’s height and ...
Work on possible neurotoxic effects of endocrine disruptors, and their possible effects on sexual orientation when a fetus is exposed to them, is in its infancy: "we mostly know about the relationship between EDC exposure and neurobehavioral function through an examination of outcomes within a limited sphere of questions."
