Puberty in females usually occurs around eleven years of age, however, it may occur younger or older depending on factors like heredity, diet and hormones. If a girl as young as eight goes through puberty, this is known as precocious puberty. This early puberty occurs more often in girls than in boys and is usually not a problem, except that puberty is occurring a few years earlier than normal. However, if a girl is sexually active at such a young age and is also menstruating, then she can potentially get pregnant if an ova(egg cell) is present in her Fallopian tubes at the time unprotected sexual intercourse is occurring. However, pregnancy at such a young age is not only dangerous for the fetus, it is also dangerous to the young girl who doesn't have the mature body of an older woman.
