Abstract
SHETTLES1 reported the possible use of the fluorescent Y-chromatin test2 for prenatal sex diagnosis in smears of maternal cervical mucus. This technique, if it works, could be very valuable, particularly during the first trimester of pregnancy when amniocentesis is impracticable. We have tested the feasibility of the technique in sixteen pregnant women who were admitted for legal abortion in the first trimester, that is, from the seventh to twelfth week of gestation after the first day of the last menstrual period.
