In a study of 960 pregnancies a significantly higher male to female birth ratio was found among primigravidae who developed HL-A antibodies, which was highest where these were monospecific. In the whole group male births predominated in women with antibodies to HL-A 1 and 11 (first locus) and HL-A 5, 12, and 13 and TYT (second locus).
在一项针对960例妊娠的研究中,发现初产妇中出现HL - A抗体者的男女出生比例显著更高,在这些抗体为单特异性的情况下该比例最高。在整个研究组中,怀有针对HL - A 1和11(第一位点)、HL - A 5、12和13以及TYT(第二位点)抗体的女性所生的男婴占多数。
