Different Response

Pregnancies with a male fetus are associated with higher risks of pregnancy complications through maladaptation of the maternal immune system. The pathophysiology of this phenomenon is unknown. A possible pathway could be a fetal sex-dependent maternal immune response, since males have a Y chromosome encoding specific allogenic proteins, possibly contributing to a different response and higher complication risks. To analyze whether fetal sex affects mRNA expression of maternal immune genes in early pregnancy, real-time PCR quantification was performed in the decidual tissue from primigravid pregnancies (n=20) between 10 and 12 weeks with uncomplicated term outcomes. Early-pregnancy decidual mRNA expression of the regulatory T-cell marker, FOXP3, was sixfold lower (p<0.01) in pregnancies with a male fetus compared to pregnancies with a female fetus. Additionally, mRNA expression of IFNγ was sixfold (p<0.05) lower in pregnancies with a male fetus. The present data imply maternal immunologic differences between pregnancies with male and female fetuses which could be involved in different pregnancy pathophysiologic outcomes. Moreover, this study indicates that researchers in reproductive immunology should always consider fetal sex bias.

Background: Because advance knowledge of fetal sex can satisfy parental curiosity and allay anxiety, attempts at its determination prior to birth have a long history. There may also be reason to determine fetal sex when sex-specific genetic disorders are suspected. The aim of this study was to investigate the association between gestational sac (GS) location and fetal sex. Materials and Methods: This cross-sectional study was conducted on 751 pregnant women. Transvaginal ultrasound was performed during 7-8 weeks of gestation for prenatal care and assessment of pregnancy sac and GS location. Age, parity, gravidity and GS location were recorded. Abdominal ultrasound was performed at 16-20 weeks of gestation to determine fetal health and sex and finally data was analyzed and compared to sex of the fetus after birth using SPSS software version 21. Results: There was a significant relationship between GS location and fetal sex (P<0.0001). However, pregnancy outcomes (male or female) and GS location (anterior or posterior) were not significant correlated (P= 0.290). There was, on the other hand, a significant relationship between outcomes and GS location (right or left) (P<0.0001). Conclusion: Maybe GS location could be considered as a helpful method for earlier fetal sex determination.
