How did ancient Egyptians test if a woman was pregnant?
Ancient Egyptians tested for pregnancy by having a woman urinate daily on bags filled with barley and wheat seeds, as detailed in texts from roughly 1400 B.C.E.. If any seeds sprouted, she was considered pregnant. This method was surprisingly effective; modern tests confirmed that high estrogen levels in a pregnant woman's urine can stimulate seed growth, with roughly 70% accuracy.
