Most people are familiar with the 51/49 ratio of boys to girls born every year. There are many theories as to why this is the rule. Some include:
- Boys are more fragile and are less likely to survive their first year
- Shettles proposed that Y-bearing sperm are faster and make it to the egg quicker than X-bearing
No matter the reason, this seems to hold true year after year.
So what are the odds of having a boy if the previous children are all the same gender? We know that if you have no children, the odds of having a boy are 51%. If you have one girl, the odds of a boy next is 54.5%. If you have two girls, your odds of having a boy for your third child drops to 46%. If you have three girls, your odds of having a boy increase to 52.7%. So, it’s not always true that statistically the more girls one has, the more likely we are to have that same gender again. The data seems to bounce up and down statistically.
The odds of having a girl actually support the 51/49 ratio because it does hold true that you are almost always more likely to have another boy if you have a boy or boys. The odds of having a boy the first time is 51%. The odds of having a girl next is 50%. If you have two boys, the odds of having a girl for your third child is 47.7% and if you have 3 boys, the odds of having a girl for your fourth child is at its lowest at 43.6%
In conclusion, it is easier to have a boy than a girl no matter what your family makeup is. So, what is one to do if you desire a boy or a girl and are facing unfavorable odds?
