Fast Facts on fetal development
- A human person’s life begins at fertilization when the father’s sperm penetrates the mother’s egg.
- From the time of fertilization, a baby’s unique DNA and genetic makeup are complete from sex to hair color to height as an adult. Fetal development is an amazing process.
- A baby’s heart begins to beat just three weeks after fertilization.
- Brain waves can be detected at six weeks after fertilization.
- At two months after fertilization, all of the baby’s organ systems are complete. The baby just needs to grow for the remainder of time in the womb.

3D ultrasound is a medical ultrasound technique used during pregnancy, providing three dimensional images of the unborn baby. Often these images are captured rapidly and animated to produce a 4D ultrasound. Below are 4D ultrasound videos from various stages of pregnancy: At 11-weeks; 22-weeks ; a 24-week and a 30-weeks (a yawning baby boy).
Where To Go in Wisconsin
Since the passage into law of Wisconsin Act 37, also known as Sonya’s Law, pregnant women in Wisconsin have the opportunity to see their child through ultrasound before making a choice about how to proceed with the pregnancy.
Here, listed by county, are the pro-life centers in Wisconsin offering free ultrasounds.
