Will it be a boy or a girl?

Some expecting couples are spending big bucks to ensure that their baby will be male or female.

One Texas couple even shelled out $100,000 on seven rounds of in vitro fertilization (IVF) in order to guarantee that they would have daughter after having two sons.

But is gender selection ethical? Dr. Jeffrey Steinberg and Dr. Carla Simonian appeared on "Fox and Friends Weekend" to debate the issue.

Steinberg said he supports gender selection, noting that it's very unusual for a couple to use IVF to choose the gender of their first child. Instead, he said, it's more commonly used by parents to balance families that already have one or more children.

"They come in with three boys at home and they're after a girl or three girls and they're after a boy," Steinberg explained.

Simonian, on the other hand, said that gender selection is a slippery slope and that "balancing the family" isn't a good enough reason for IVF.

"As physicians, we're obligated to limit our patients' choices. Certain things are not ethical. And I think that choosing our child's sex is unethical, unless it's for medical reasons," Simonian stated.

Steinberg asserted that in the U.S., there is the liberty of reproductive choice.

"As human beings, we've got this built-in need for balance," Steinberg said. "Women are very important. Men are very important. And there's something built in to us that says we should be balanced. And that's really what's driving all this."
