Historical and clinical evidence confirms that Western medicine increasingly utilized scientific methods, such as ultrasound, biochemical assays, and genetic screening, to predict prenatal diseases and disabilities beginning in the twentieth century.
The claim specifies that Western doctors began predicting prenatal diseases and disabilities with scientific methods in the 20th century. Papers [1], [2], and [11] explicitly detail how the 20th century saw the introduction of ultrasound, genetic testing, amniocentesis, and biochemical markers that enabled prenatal diagnosis of congenital diseases and malformations. No sources refute this timeline.
