During pregnancy, you may find your baby's appearance just as interesting as his internal development. Later in pregnancy, you may be able to see a significant amount of your baby's external development during an ultrasound. However, you can...
A baby goes through tremendous growth and development during its 40 weeks in a mother's uterus. With so many changes occurring, prenatal care is essential to monitor the health of the baby and the mother to ensure a healthy pregnancy and delivery.
During the 38 to 42 weeks of a typical pregnancy, a fetus develops in the mother's womb. The mother's egg is fertilized by the father's sperm to produce a single cell called the zygote. This develops into a ball of several hundred cells called the...
The human fetus develops according to a set of precisely ordered and timed stages. The mother's egg is fertilized by the father's sperm and becomes a zygote---a single cell containing a new, complete set of DNA. This zygote rapidly divides and...
Pregnancy due dates are calculated by adding 40 weeks to the date of your last menstrual period. Technically, during the first two weeks of this time frame, most women are not yet pregnant. Fertilization occurs at week three when the sperm and egg...
A 30-week fetus is only ten short weeks away from his due date, and development is proceeding at a ferocious pace. At this point, the baby has completed most of the development of major organs and is concentrating his efforts on growing larger,...
Pregnancy is a time of rapid growth and change for Mom and the baby. Pregnancy is divided into trimesters, and a full-term pregnancy is 40 weeks. It's normal to wonder about the growth of your fetus and his formation, and what bodily changes are...

During the 40 weeks of pregnancy, as your belt tightens and your belly expands, your baby transforms from a single-celled organism into a fully formed fetus prepared to survive outside the uterus. Although growth and development continue after...
Shedding excess pounds can improve your sense of well-being and motivate you to lose more weight. However, continuing to lose weight until you are medically underweight has many potential negative health consequences. Several common symptoms arise...
Before the fetus is born, a precisely ordered and timed set of developments takes place. Over the course of eight weeks, a single, fertilized egg cell grows into a ball of cells called the blastocyst, then an embryo and then a fetus. The fetus...
An average pregnancy lasts 40 weeks and is divided into three periods of time called trimesters. During each of these stages a baby undergoes incredible growth to transform itself from a fertilized egg into a human being.
Though their time in the uterus is relatively short, babies undergo amazing changes from conception to birth. After only about 40 weeks, they have changed from a tiny ball of cells to a full-term infant, ready to survive in the world. During each...
Your baby may have come into this world with a full head of hair, while another infant may be nearly bald. Newborn hair, or the lack thereof, matters very little because it will more than likely fall out and be replaced by very different hair,...

After the mother's egg cell is fertilized in one of the fallopian tubes, it embeds itself in utero--meaning, in the uterus--where it develops into a full-term baby over approximately 38 weeks. This developmental process is impressively consistent...
Pregnancy is a time of rapid development for a baby who begins with only two cells and eventually forms into an entire person. The growth of a baby before birth involves the complex process of change in physical features each week over the course...
If you have excess weight to lose, you naturally might be impatient to shed the pounds as quickly as possible; however, overly rapid weight loss can lead to a range of medical problems and symptoms. A safe and permanent rate of weight loss is...
When the mother's egg is fertilized by sperm, it forms a single cell called a zygote. The zygote grows into a ball of cells called a blastocyst and embeds itself into the wall of the mother's uterus. Over the subsequent two weeks, it becomes an...
