On chapter 515 they mentioned all Kuja Tribe women always give birth to
females.

How is this possible? Is there any explanation about this?

question
one-piece
Why are all members of the Kuja tribe born as women?


Unless the one piece author/s clarify the existence and origin of the Kuja
tribe, there would be no accurate answer for this question. It happens most of
the time in any anime and one piece is not an exception, let's just wait for
any episodes where this tribe will be explain even more. For the meantime the
succinct explanation of the Kuja tribe are as follows:

No explanation is ever given beyond the word "mysteriously" but it isn't as
ridiculous as it sounds.

In the real world, environmental factors such as the temperature and diet of
the mother during pregnancy can affect the likelihood of a boy or a girl being
born. Of course it rarely gets above 55-45 one way or the other, but in the
unique environment of Amazon Lily it is possible that the odds of having a
baby girl is completely overwhelming, to the point where no boy has ever been
born on the island.

The most simple answer would of course be "Magic" or anime logic.

However, when we look at the issue from a logical standpoint, we don't need to
look at the tribe, but at the foreign countries, since the gender of the
newborn is determined by the winning sperm, which either carries a female
chromosome (X) or a male chromosome (Y).

Maybe the males in the foreign country only produce female sperm. Sperm
production is affected by enviromental factors but this is unlikely, there'd
be reports of that foreign country having female births (unless their females
travel and get impregnated somewhere else as well). Keep in mind it's entirely
possible that those reports could exist but the reader never gets told of any
of this.

Most likely is that the tribe actually gets males born, but they are promptly
killed (and no record of them is kept), much like [real Amazon
tribes](http://en.wikipedia.org/wiki/Amazons) did it.

Actually this might not be true. There may have kids being born as boys but
due to some reasons the boys did not lived. In short, the elders are trying to
prevent from boys being alive. I believe this is somewhat similar to what
happened with Vincent(Hiei from Yu-yu Hakusho) wherein he was an outcast
because of the tradition of having only female to live in their village.

Or maybe while they're out in the world, they did give birth to boys but was
like 'oop! You're a boy; orphanage for you' and just only took home the girls.
Remember, them getting pregnant requires them to leave the island OF WOMEN to
go into the world OF MEN. So only people who left would know for sure. Who
says they have to tell anybody they had a boy? Or that they were pregnant at
all?
