Abstract
Key Clinical MessageThis case report illustrates that in vitro fertilization (IVF) may be a potential risk factor for pregnancy‐associated osteoporosis (PAO), highlighting the need for awareness and monitoring of bone health in women undergoing IVF treatments. PAO is a rare disease resulting from an imbalance of calcium in the body during pregnancy and lactation and presenting with fragility fractures. PAO occurs in late pregnancy or early postpartum period. A 28‐year‐old woman who conceived through IVF experienced severe back pain 2 days after delivery. Magnetic resonance imaging of the spine showed wedge‐shaped fractures of T9‐T12 vertebrae. Bone mineral density (BMD) was low on dual‐energy x‐ray absorptiometry. The laboratory tests were within the normal range. Based on the clinical manifestations, osteoporotic spine fracture, results of BMD, and exclusion of other causes of osteoporosis, the patient was diagnosed with PAO. Considering the deleterious effect of treatment with gonadotropin‐releasing hormone and repeated superovulation on bone, we hypothesized that IVF may be an etiological factor for PAO.
