At what stage is a babies sex determined?

A fetus sex is determined by the sperm at the time of conception. The sperm will either carry an X or y chromosome which will mate with the moms X to make either a boy Xy or girl XX. The actual sex of the baby cannot be seen until approx 18 wks via abdominal ultrasound.

During the second trimester which is 14 through 27 weeks through the pregnancy. To be more specific sometimes they can determine as early as 4 months but normally they do the ultra sound for sex determination at 5 months.

What a strange way to descibe a foetus.
I think the sex of an embryo is determined as soon as the egg is fertilised. I may be wrong.
