Baby Boom

Colorado already has several noteworthy reputations. But add one more to the list: baby-making.

The state's fertility clinics are known for their highly successful fertilization rates.

Some clinics boast success rates as much as 50 percent... nearly double the national average.

That distinction draws wanna-be parents from all over the world to the Colorado.

Scientists at the clinics are busy merging sperm and eggs to meet the huge demands.

It's not clear why those clinics are so good at what they do.
