Nub theory – tin can yous predict if you're having a boy or girl?

Co-ordinate to nub theory it's possible to predict your baby's sexual practice at the 12-week browse. The idea, known as the 'bending of the dangle', suggests that you lot tin tell the sex of your baby at your very commencement ultrasound.
Nub theory explained by a doc
"Nub theory is to do with what we can potentially encounter on the 12-week scan," says our expert GP Dr Philippa Kaye.
"The purpose of the 12-calendar week scan is a dating scan, to check how many babies nosotros have in at that place, and that there is a heartbeat. They're not to going to look at the genitals at all.
"Before the genitals are formed there'southward a bump or nub called the genital tubercle / tube.
"The basis of the theory is that this tube causes an angle with the lower part of the spine – and if that angle is less than 30 degrees it'southward a girl, and if above it'south a boy."
Nub theory – daughter example
This paradigm was shared on our forum, and according to nub theory – it'due south a girl – as y'all can see, the bending of the 'nub' is less than 30 degrees.
Nub theory – boy case
This scan pic was shared on our forum by jwebster82.
We recollect the angle here looks less than 30 degrees, in fact, information technology's apartment – which, according to nub theory, means information technology's a girl. But the baby turned out to be a boy.
Is nub theory scientifically proven?
No – there's no solid scientific research into whether or non nub theory really works, and that's because about medics merits it's just as well early on to accurately predict a baby's sex activity at 12 weeks.
"There is no bear witness that it works," reiterates Dr Philippa. "It's said it works 50% of the time – that's equally skillful as guessing – so I wouldn't go for information technology."
And anecdotally, it seems that nub theory 'works' for some and non for others. On our forum, mum Gazsgirl says: "Mine was right at 12 weeks, the nub was level and at my xx-week scan information technology was confirmed I am having a girl."
While another of our forum members, Huxley, who has had some experience as a sonographer tells us: "I'one thousand a radiographer with a bit of feel in sonography and I'm agape I tin't tell from scan pics what the sexual activity is.
"The best manner is to take an image of between their legs at 17 weeks onwards and see from there! I just read about the nub theory, it's interesting but I'm not sure I'd trust it till a lot more research had been done on it."
And when we contacted the Royal College of Radiologists, a spokesperson advised that one of their obstetrics radiology leads in that location has said using nub theory to predict your baby's sex activity is possible, only extremely hard.
"He said no hospital trust routinely offers sexing at 13 weeks (when you're talking about for nub testing), as it makes sense to look and exist more confident," she went on to say.
"Unless they accept a local policy against doing it (usually due to cultural demographics), nigh ultrasound departments will sex babies at 20 weeks, with the usual proviso that information technology is non fool proof."

Can nub theory exist incorrect?
In a word – yes. In all honesty it's a bit of a guessing game. To see the nub your baby needs to exist lying on their side, not curled upwardly and they demand to be as flat equally possible.
"Up until your 14th or 15th calendar week browse, the female and male genitalia simply look too similar to 100% differentiate between the two. This can potentially atomic number 82 to inaccuracies if a result is given before this point," says Dr Geetha Venkat, who specialises in fertility treatments.
"It is very difficult to identify internal or protruding sexual organs until they are suitably developed. With this in heed, it is meliorate to exist patient and wait until the appropriate scan when discovering the sex of your infant, and call back the most important thing is that they are healthy."
