If you or someone you know is trying to have a baby you probably realize it's not always easy.  In fact, 1 in 8 couples struggle with infertility.

The good news is advancements in reproductive medicine have dramatically improved.  Not only are more people having success, but they're not forced to risk having twins, triplets or more as often.

As part National Infertility Awareness Week 9NEWS is highlighting some important topics that you or someone you love will want to know about whether you’re struggling with infertility or want to have a baby down the road.

Dr. Eric Surrey with the Colorado Center for Reproductive Medicine will join us Tuesday on 9NEWS at NOON to talk about the latest advancements. 

Dr. Surrey says while the idea of twins or triplets sounds cute and fun, when a women gets pregnant with multiples the risk of complications for mom and the babies increases dramatically.

Ten years ago, CCRM pioneered genetic testing called comprehensive chromosomal screening.  Dr. Surrey says this is a process that checks to make sure an embryo has all 23 pairs of chromosomes. A genetically 'normal' embryo has a much higher chance of turning into a successful pregnancy and a lower chance of miscarriage.

So with that increased chance, doctors have more confidence in transferring just the one embryo.
