Cartilage damage is a relatively common type of injury. It often involves the knees, although joints such as the hips, ankles and elbows can also be affected. Cartilage is a tough, flexible tissue found throughout the body. It covers the surface of joints, acting as a shock absorber and allowing bones to slide over one another. It can become damaged as a result of a sudden injury, such as a sports injury, or gradual wear and tear (osteoarthritis).
While it is still too early to clearly make out boy or girl parts at 12 weeks gestation, apparently the gender can be determined based on the angle of the nub (the genital tubercle). To determine gender based on a 12-14 week ultrasound, a profile view of the genital region is needed.
At around 18 to 20 weeks, you will have an ultrasound to check your babyâs development, identify any problems, and possibly even identify the sex of your baby. Itâs important to remember that it is not always possible to determine the sex of your baby at this stage and you wonât know for sure until your baby is born. To determine the sex of your baby, the ultrasound technician or obstetrician will look for the presence or absence of a penis on the ultrasound. Keep in mind that this method of determining the sex of your baby is not 100% accurate. A visual effect may create or obscure the image of a penis on an ultrasound.
