Ok. So now let's talk about if there is any science here. And the answer is...perhaps surprisingly...maybe.
You may have heard of the "beautiful women have more daughters" idea that's discussed here:
Do Beautiful Parents Have More Daughters? | DiscoverMagazine.com and that this even dates back to childhood, with attractive children (both male and female) having more daughters than those who teachers rated as "less attractive"
https://www.psychologytoday.com/us/b...more-daughters (I always KNEW my teachers were secretly rating us students by attractiveness LOL) Additionally some evidence indicates attractive men pass their looks to daughters and manly men pass their manliness onto sons LOL
https://www.telegraph.co.uk/news/new...n-to-sons.html (and please no one freak out about this, it's not saying that boy moms are ugly, it's a small statistical variation. if you read the actual study they found that very attractive and also the least attractive group had more daughters, while everyone in the middle, the attractive, neutral, and less attractive people had more sons)
So the question is, if this is true, then why. The obvious answer is differing levels of hormones that could then predispose people to be more likely to have more of one gender than the other. Here is an article about male faces, testosterone, and gender conceived
Higher Testosterone Levels Leads to 'Manly' Faces and another that purports higher estrogen = more attractive female face
Higher Testosterone Levels Leads to 'Manly' Faces It may even be the case that super manly men are extra attracted to the most beautiful women

What does this all mean?? Well, it means that ~maybe~ you can tell something about a person's hormone levels by looking at their face. MAYBE. I mean seriously, look at this link again, the faces are barely different

https://www.livescience.com/10073-wo...hill-guys.html These faces are BARELY DIFFERENT. And in this one
Higher Testosterone Levels Leads to 'Manly' Faces they basically just went and dug up celebrities that supported their hypothesis (and many of them had both boys and girls anyway)
Higher Testosterone Levels Leads to 'Manly' Faces It was not very scientific, not at all. Thus I do not believe that some sketchy dude on FB can tell just by looking at a person, the gender of their offspring. Just not a thing I can buy into at all.
Not to mention the fact that testosterone and estrogen levels have never been proven to sway gender anyway. All this is speculation based on a few studies that used things like 2d4d ratios (finger length) and answers on personality tests to declare a person high in testosterone or not without doing actual blood tests just prior to conception (if you are aware of a study like this being done, using blood tests and hormone levels prior to conception, please hit me up with it, would love to read it) So much of this is based on the concept of "testosterone sways blue" and then researchers seem to take that as a given and make their study accordingly as if it's been proven when it hasn't. And a lot of researchers think (myself included, and I'd even go so far as to say I believe this more than the testosterone idea these days) estrogen may sway blue but estrogen = more feminine = more beautiful = more girls?? It's all very interesting and fun to speculate about but we need more information.
Additionally, we've had some reason to doubt testosterone in and of itself swaying at all anyway. Clomid raises testosterone but has been one of our best pink sway tactics when taken by women. Supplements like l-arginine that blue swayers used to take to raise testosterone actually seemed to cause a lot of pink opposites, so overwhelmingly so that I dropped it within only 2 years of the dawn of this site. We have anecdotally seen lots of men who are bald, who have all girls (such as Bruce Willis). Baldness is partially caused by testosterone and precursors of testosterone, and we have had a fair amount of success for pink sways using finasteride or similar medications that help with hair loss...even though they make hair grow, they actually RAISE testosterone levels - but we've still gotten mostly girls with men taking them. And we have also anecdotally seen lots of guys who are "juicing" with steroids while bodybuilding and whose T levels are through the roof, have many girls (as have bodybuilders themselves, here's one of many threads on the subject
https://www.steroidology.com/forum/g...ile-juice.html)
So, this is a long drawn out explanation to say, no, even though there is some intriguing science surrounding this concept that definitely needs more investigation, it is not possible to tell a person's offspring's gender based on their facial features, because even IF you could tell their testosterone levels from a picture (unlikely) we don't even KNOW that testosterone levels alone are doing anything at all and in fact some evidence seems to debunk the idea.
