Now, British doctors report that male and female fetuses really can affect mothers differently.

Before a female fetus is born, she has up to seven million egg cells.

Estrogen, for instance, is present in both the male and female fetus.

The selective termination of a female fetus is most common.

Also, female fetuses tend to weigh less than males, at full term.

Taking testosterone while you are pregnant can cause a female fetus to develop male traits.

A 10-week-old female fetus has already made all its eggs, about six million to seven million, he said.

There is considerable evidence that more male than female fetuses are conceived and born.

Ucchuṣma was also thought to be able to change a female fetus into a male one.

This is a condition that causes female fetuses to look some male.
