HOUSTON -- A Houston couple tried for years to have a baby, but a common fertility problem got in their way. Now they have a beautiful baby boy, thanks to doctors at Baylor College of Medicine, News2Houston reported Tuesday.

Melissa and Steven Grissom started trying to have a baby three years ago.

"I've always described the perfect occupation for me is to be a mom," Melissa Grissom said.

But a common condition called polycystic ovarian syndrome made it impossible. Melissa did not ovulate so her menstrual cycles were irregular.

"The frustration of it is the uncertainty," she said.

Melissa found help through Baylor infertility expert Dr. John Buster.

"When it doesn't happen for you, and the months and years go by and you're left out of something that seems to be awesome -- that's what tears people up," Buster said.

Buster said PCOS is easy to treat in many cases. Baylor is studying new drugs that regulate cycles.

"With glucophage, the levels of insulin are reduced to normal. These women are able to cycle in a normal way and become pregnant very quickly," Buster said.

It worked for Melissa, but then tragedy struck -- she lost the baby at 10 weeks.

"It's a roller coaster of emotions -- every time you have hope and faith that it's going to work. When it doesn't, you're back down again," she said.

Three months later, Melissa got pregnant again. Nine months later, Adam was born -- perfectly healthy.

"Seeing Melissa with Adam, when we came home, it was wonderful. I could just see the joy in her eyes knowing how long it had taken -- all the effort we had put into it -- was just a wonderful, wonderful feeling," Steven Grissom said.

A few months ago, the Grissoms found out that they are expecting another child. This time, no treatments were needed. The baby is due in May.

Buster said the PCOS could have gone into remission with the birth of Adam.

Doctors said symptoms of PCOS are easy to spot. It's prevalent in Hispanic women, it causes irregular periods, it can also cause acne and facial hair, and most patients who have it are overweight.
