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.
An ultrasound is perhaps the most common way to detect the sex of your baby. With an ultrasound, you can probably not detect the sex of yore baby until sometime between week 16 and week 20 of pregnancy. Having said that, there are a great many factors that go into how early you can detect the sex of your baby using an ultrasound. Everything from gestational age to the thickness of the motherâs abdominal wall can affect the amount of time that this process will take. An ultrasound is, after the 20th week of pregnancy, generally more than 90% accurate at being able to tell a babyâs sex.
