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 steroid hormones include estradiol, which is an estrogen, or female sex hormone, and testosterone, which is an androgen, or male sex hormone. These two hormones are released by the female and male reproductive organs, respectively.
