Return to Fetal Development Overview
- At 23 weeks pregnant, proportions of the body are now quite similar to a newborn although thinner since he hasn't begun to form body fat.
- Bones located in the middle ear harden.
- Your baby is able to hear. (Dads, did you know: low-frequency sounds mimicking a male voice penetrate the abdomen and uterine wall better than the higher frequencies of the female voice?)
- The eyes are formed, though the iris still lacks pigmentation.
- The pancreas, essential in the production of hormones, is developing steadily at week 23 of your pregnancy. She has begun producing insulin, important for the breakdown of sugars.
- If born now, after 23 weeks of pregnancy, your baby has a 15% chance of survival, his odds going up with each passing day.
- The average baby at this stage weighs 1.1 pound (501gm) and is 11.38 inches (28.9cm) long.
