Transvaginal ultrasound measurement of the yolk sac and transvaginal amniocentesis were carried out on 94 women prior to first‐trimester termination of pregnancy. Maternal serum and fluids from the amniotic cavity and extraembryonic coelom were analysed for alpha‐fetoprotein (AFP). No correlation was found between the yolk sac size and the levels of AFP in any of these sites.
