Possible to see gender from profile shot? Scan at 20/21 weeks :)

Hi I came across this photo in my scans, and I can see 3 lines at the end that I’ve drew an arrow pointing towards. Is this showing a girl or is this unrelated to gender? Can you see gender from a profile shot? Any help greatly appreciated 😀 thank you

At 20 weeks a potty shot is better. Boys can appear to have three lines as well, depending on the angle.

So is that area the genitals then? And you’re saying that could still be a boy?
