R.B.
Please try Dr. Karen Lee at DFW Fertility Associates at Presbyterian Hospital in Dallas. I am now a new mom at age 41 because of them. Her associate, Dr. Chantillis, is also highly recommended. Their website is dfwifv.com.
I was diagnosed with unexplained infertility, and decided at age 40 that I wasn't giving up the idea of motherhood. Luckily, they provided options that worked for me.
