Sex Organs Are Visible. Although your baby's gender is determined immediately upon fertilization, you will not be able to know the sex until about the 16th to 18th week of pregnancy. At around the sixth week your baby will develop a small bud called the genital tuber at the site of the genitals.
Hearing in the womb. The ear begins to develop during the third week and at twenty weeks a baby's ear resembles an adult's in shape and size. Four weeks later the hearing is fully developed, and a baby can hear voices, music and other sounds outside the womb. The sounds in the womb are muffled, but the melody and rhythm of music are not much altered. A baby's brain registers rhythmic patterns, and changes in beat and melody are picked up.
