Although sonographic fetal sex determination is feasible in most pregnancies, in some cases, it may pose difficulties. An attempt to determine the fetal sex should not be made before 12-weeks’ gestation because this early, it is relatively inaccurate. After 13 weeks, it is accurate in 99% to 100% of cases without malformed external genitalia. Sonographic fetal sex determination in the late second trimester is based on direct visualization of the external genitalia, whereas in the late first and… Expand
Use of B-mode ultrasonography for fetal sex determination in dogs.
TLDR
The sonographic appearance of the external genitalia in canine fetuses in utero associated with a specific position of the fetus is described and it is reported that sex determination is possible between 55 and 58 days of gestation. Expand

Determination of fetal sex is an integral part of routine second trimester ultrasound examination in pregnancy and it is usually accomplished whereas the first trimester is being limited mainly byExpand
The ultrasound identification of fetal gender at the gestational age of 11–12 weeks
TLDR
The present study had a much higher gender identification accuracy compared to other studies, and the final success of fetal gender identification was about 91% in the 11th and 12th weeks of pregnancy. Expand
Foetal sex determination at the second trimester anomaly scan in Denmark.
TLDR
An initial overview on the practice of foetal sex determination in Denmark and the accuracy of the examinations at the second trimester anomaly scan at a regional and a university hospital is provided. Expand

TLDR
The prevalence, sensitivity and accuracy of ultrasound sex determination have been established in this study and subgroups identified that request this information. Expand
Discordant fetal sex on NIPT and ultrasound
TLDR
The aim of this article is to review cfDNA and ultrasound diagnosis of fetal sex, identify possible causes of phenotype‐genotype discordance and provide a systematic approach for clinicians when counseling and managing couples in this circumstance. Expand
The Determination of Fetal Gender with Gestational Sac Volume Maternal Age and Body Mass Index
TLDR
It is found that GSV, maternal age and BMI have no effect for determination of fetal gender which is very important for hereditary diseases in early pregnancy. Expand
Reliability of Fetal Sex Determination Using Maternal Plasma
TLDR
Noninvasive fetal sex determination in maternal plasma is highly reliable and clinically applicable and can be applied to male-bearing and female-bearing pregnancies. Expand
Case Report: Prenatal Genetic Counseling to Parents of Fetuses Suspected of Having Ambiguous Genitalia
TLDR
Prenatal genetic counseling provides reassurance to parents, who remain informed and emotionally secure throughout the legal sex assignment of their child. Expand
Early non-invasive detection of fetal Y chromosome sequences in maternal plasma using multiplex PCR.
TLDR
Fetal sex assessment by detecting Y chromosome sequences in maternal blood can be routinely used from the 6th week of gestation and can avoid conventional invasive methods of prenatal diagnosis. Expand

Early determination of fetal sex using transvaginal sonography: Technique and pitfalls
TLDR
The main diagnostic criteria for male gender determination by TVS are the “dome” sign representing the sonographic visualization of the fetal scrotum, the cranially directed phallus, and the longitudinal raphe at the base of the penis. Expand
Fetal sex determination by high resolution ultrasound in early pregnancy.
TLDR
Fetal sex assignment in the late first and early second trimester can be useful in pregnancies at risk for severe sex-linked diseases, in fetal disorders involving the genitalia, and in the individual identification of multiple fetuses. Expand
Sonographic determination of fetal gender before 25 weeks gestation.
TLDR
Sonographic determination of fetal gender was attempted prospectively in 121 consecutive routine obstetric scans between 10 and 25 weeks gestation and a higher number of males than females in the group in whom the gender of the fetus could not be detected by sonography. Expand

TLDR
The method of ultrasonic examination of the fetal sex reported here appears to be feasible in obstetric practice with consistent reproducibility and a high incidence of correct determinations at 12 weeks of gestation and thereafter. Expand
Sonographic determination of fetal gender.
TLDR
With the advent of high resolution real-time sonographic scanning machines, fetal gender can be determined in most pregnancies of more than 25 weeks and lack of visualization did not imply a female perineum, and caution of potential psychological effects on the parents is raised. Expand
Fetal Sex Determination by Ultrasound
Real time ultrasonpgraphic examination of the fetal perinea! area after 30 weeks of gestation can reveal the external genitalia of the male fetus. The absence of this finding indicates a femaleExpand

TLDR
The majority of prospective parents wish to know the sex of their child, and, in most cases, it is possible to determine the fetal sex at the time of the routine anomaly scan, which would appear reasonable to provide this information. Expand
