Why Do So Many Women Have Boys After Already Having A Girl?

By: Sandy Dean:  I sometimes hear from people who firmly believe that the gender that they have during their first pregnancy will have some impact on the gender of the second baby or on subsequent babies.  Some people believe that if you get a girl first, then you’ll likely have a boy for the second.  And some believe that if you have one gender, then you are predisposed to that gender and then you’ll either have a houseful of girls or boys.

People often tell me that they believe these things because they’ve seen them happen with their family or friends.  An example is the person who says they notice that nearly every one who has girls with the first baby is likely to have a boy the next time.  Someone might explain: “I have three very close girlfriends.  We all graduated from college at the same time.  And all us (except for me) now have two children.  Every one of them had a girl followed by a boy.  I had a girl for my first child.  And I’m wondering if the odds are now stacked against me for me having a girl.  I’d like to have two girls before I have a boy.  I am very close to my sister and we are close together in age.  I would like for my daughter to have the same experience. I would like to give her a sister.  What is it that makes women have boys after they have a girl?  And how do I get around this so that I can have two girls in a row?”

I honestly think that what you are seeing among your friends is a coincidence.  I am the oldest of four girls.  I can look at my three best friends and notice that their families are vastly different.  One of them had two sons followed by a girl, one has two girls, and the other has a girl followed by a boy.  As you can see, these families (and the genders within them) are extremely varied.

Frankly, a baby’s gender is determined by which of the father’s sperm fertilizes the mother’s egg first.  Men have equal amounts of girl and boy producing sperm.  And this sperm ratio does not change after a man fathers children, regardless of his child’s gender.  He has roughly a 50 / 50 ratio every time he has intercourse and every time he attempts to father a baby.  This does not reset or change because of any previous outcome.

Now, there are certain things that seem to skew the roughly 50 / 50 odds.  It’s said that more boy babies are conceived in winter.  It is also said that as women age, they are more likely to have girl babies (which contradicts the theory that most women have a girl first and a boy later.)  However, these odds are only skewed very slightly.

Plus, the mother’s vaginal PH, the timing of conception as it relates to ovulation, and sexual positions matter too.  Frankly, I believe that these things matter much more than the gender that you have already had.  Because regardless, you are still dealing with equal amounts of girl and boy sperm (based on sperm alone) before you factor in those variables that I addressed above.

If you have had a girl and want another girl, then you are better off evaluating your PH (and trying to ensure that it is acidic,) using deep vaginal penetration when having sex, and carefully monitoring your ovulation rather than telling yourself that you will probably get a boy this time.  The truth is, your odds are the same as they were the first time – nearly 50 / 50.  You can tweak those odds by being careful with how and when you conceive.  But there are no rules of nature that dictate which gender you get  and when you get it.  The result depends on which sperm makes it the egg.  And the sperm are present in equal numbers unless you do something to discourage them.

Luckily, there is plenty of easy steps to take in order to discourage them.  I’ve put together a few websites that explain it step by step. If you want a girl baby, see http://conceive-a-girl-baby.com If you want a boy, check out  http://conceive-a-boy-baby.com
