Question: How accurate are ultrasounds in determining gender?

The results of this study indicate ultrasound gender predictions by sonographers are 100% sensitive for accurately predicting the gender in the second and third trimesters. The overall success rate of correctly identifying fetal gender in the first trimester was much lower (75%).

What are odds of having a boy or girl?

My general response is that its a 50/50 chance that a woman will have a boy or a girl. But thats not exactly true – theres actually a slight bias toward male births. The ratio of male to female births, called the sex ratio, is about 105 to 100, according to the World Health Organization (WHO).

What determines if you have a boy or a girl?

Biological sex in healthy humans is determined by the presence of the sex chromosomes in the genetic code: two X chromosomes (XX) makes a girl, whereas an X and a Y chromosome (XY) makes a boy. In this way, it is the presence or absence of the Y chromosome in a healthy human that differentiates boy from girl.

Is there a way to guarantee having a girl?

Theres only one guaranteed way to conceive a girl, which is a procedure known as sex selection. This in vitro fertilization method (IVF) involves implanting a girl or boy embryo into the mothers uterus.
