External genitalia

Indifferent stage


In horses, the identification of fetal sex by location of the genital tubercle between 55 and 70 days of pregnancy is hampered by the large amount of allantoic fluid, extensive fetal movements and the extremely long umbilical cord; however, reliable results have been achieved by ultrasonographic evaluation of the fetal gonads at 110–150 days of pregnancy.

In human, the ultrasound gender scan is probably the most common way that parents discover the sex of their baby. As far as we know, we have a 100% accuracy gender prediction rate over 16 weeks.
