Pigeon chest, also known by its medical name pectus carinatum, is a moderately rare congenital condition that causes the sternum to stick out. One of the side effects of trisomy is risk of miscarriage. In males, such abnormalities may include failure of the testes to descend into the scrotum (cryptorchidism) and/or low levels of testicular function (hypogonadism), resulting in delayed development of secondary sexual characteristics (i.e., deepening of the voice, characteristic hair growth patterns, sudden increase in growth and development of the testes and scrotum, etc.). such abnormalities may result in life-threatening complications. accounting for at least 15% of first-trimester pregnancy losses. Each chromosome has unique regions or bands that contain genes, and each band is labeled numerically. Get prescriptions or refills through a video chat, if the doctor feels the prescriptions are medically appropriate. National Organization for Rare Disorders.
