A 38-year-old woman in Nairobi had been trying to conceive for eight years. Her periods were regular and painless. She had no chronic illnesses. Her husband, 40, was healthy and had none either. Nothing in the history pointed anywhere.
Then a pelvic ultrasound found a two-centimeter streak of calcification sitting inside her uterine cavity. Her ovaries and adnexa looked normal. When gynecologists went in with a hysteroscope, they saw a white plaque the report describes as coral-like, sitting in the lining of her uterus.
