The ultrasound diagnosis of retained fetal bones in West African patients complaining of infertility.

Prolonged retention of intrauterine bone is a recognised cause of secondary infertility. Between 1989 and 1995, eleven West African women had retained intrauterine bone as the cause of their infertility. All the women had had termination of pregnancies in their countries of origin. Transvaginal ultrasound scan detected bright intrauterine echoes suggestive of bone which was confirmed and removed at hysteroscopy. Subsequently eight women conceived spontaneously 12 pregnancies. Doctors treating West African women with infertility should be aware of this condition and include transvaginal ultrasound scan in their investigations.
