Prediction from Human Fetal Measures

Fetal Movement: Development and Time Course

“…Fetal development has typinot been adequately described for cally been evaluated from the mother's either the normal or defective fetus, report of fetal activity (1,2 Eight pregnant women were asked to record every fetal kick felt during the waking day, from the first day a kick was noticed to the time of birth. Fig.…”

Investigating the relationship between fetus heart rate in the first trimester screening with fetus sex

“…While in our study, only mothers who referred for routine screening ultrasound were examined and pregnancies with complications were excluded. 12 Also these patients entered the study under 14th week of pregnancy and it is possible that FHR be slower in 6-7 weeks of pregnancy compared with 8-14 weeks.20 Our study was conducted at 11th and 14th week of pregnancy. During this period, the minimum FHR fluctuations occur in pregnancy.…”

“…14 In other similar studies, it was shown that contrary to public perception about faster FHR in girls, there was no difference between boys and girls in this point. 12,[21][22][23] Up to now, the studies done about the relationship between FHR and fetal sex often had very low sample size. 19,24,25 On the other hand, most of the studies are done in a big range of pregnancy and are often performed in the second and third trimester of pregnancy.…”

“…10 However, in previous studies very contradictory results have been reported regarding the predictive power of this method. 11,12 Till now, few citable studies have been performed around the world and Iran about the predictor role of FHR in determining fetus gender in early pregnancy. [12][13][14] Different factors are important to measure FHR that have not been mentioned in most previous studies including how to measure FHR, FHR changes, gestational age, maternal age and mother's gravid and parity.…”

[15][16][17] Due to the above-mentioned evidence, it seems that early detection of fetus sex in the first trimester of pregnancy can effectively reduce morbidity and mortality in fetus and newborn by providing supportive measures by doctors and parents.…”
