As a whole, skeletal dysplasias are not common. They affect one in every 4,000-5,000 births, although the incidence may be higher since the symptoms may not manifest until early childhood, when short stature, joint abnormalities or other complications arise.
Role of Hormones in the Body. Hormones play a role in nearly every aspect of the bodyâs day to day functioning. For example, they regulate sexual functioning, menstruation, pregnancy, bone health, and the bodyâs overall mood and emotions.
Examples of hormones are estrogen, progesterone, testosterone, and thyroid hormone. In a womanâs body during the menopause transition, the months or years right before menopause (her final menstrual period), levels of several hormones, including estrogen and progesterone, go up and down irregularly.
