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.
Best Answer: Depends on how nice your sonographer is. It IS possible to tell the sex at 17 weeks, as the baby's sex organs have formed by 14 weeks apparently, but many dont want to commit to telling so early, or it may not be as clear, so the usual is at 20 weeks. I found out the sex of my baby at 16 weeks, but only because of an absent minded slip of the tongue..
