Angeline N. Beltsos, MD Q & A

What do you like best about being a physician in reproductive medicine?



It is a unique job being able to combine state-of-the-art science with the miracle of life, and fulfilling couples lifelong dream of having a baby. Reproductive medicine is an ever-changing area of medicine so using high tech scientific advances in clinical practices is very exciting. I have an amazing group of nurses, doctors, laboratories, and staff that make Vios one of the best places to practice reproductive endocrinology in the world today.

Why did you choose to work in the field of reproductive medicine?


While I was a medical student and rotated through a part of the hospital labeled “IVF LAB,” I was immediately impressed with the potential of their work that day. In that moment, I decided that my studies would be geared toward the goal of becoming a reproductive endocrinologist.

What are your special areas of interest in reproductive medicine?


I have special interests in helping women over 40 achieve pregnancy, which can be challenging as her ovarian reserve may be decreasing.

Another area of interest is preimplantation genetic diagnosis or screening. The team taking care of Vios patients are leaders in the field of using the latest blastocyst biopsy techniques and advanced screening of all 24 chromosomes, Including next gen sequencing. Our lab is also one of the only in Chicago including mitochondrial science in analysis of embryos.

Third party reproduction is also an exciting area of REI for me, and offers the opportunity to build a family using a gestational carrier, donor eggs, or donor sperm. Illinois is one of the friendlier places in the US and world for families needing this type of fertility care. I have also been participating in PCOS clinical research and patient care.

What do you do for fun in your spare time?


I like spending time with my husband and children, dancing, golfing, bike riding, and traveling. Hobbies include photography, reading, and watching hockey games.

What is something most patients don’t know about you?

As life had it, we also needed a gestational carrier to have my last child. It reminds us that everyone has a story, and there are solutions to help you achieve what you dream. As you go through this, remember to give yourself time and space to make important decisions but also to keep an open mind.

What does it feel like when you have helped a couple to become a family?

Helping someone start their family or add to it, whether it be just a small nudge of treatment or more involved care, it is truly one of the most humbling experiences of my life. Some of my fondest memories are being invited to a baptism or birthday party where the joy of this child's being is shared amongst the parents and their entire family and community.

What’s the most memorable experience you have had as an REI?

Aside from the personal joy of being a doctor, I have truly been grateful for the opportunity to start and lead the Midwest Reproductive Symposium international. This amazing meeting of the minds, has allowed me the chance to build friendships of thought leaders and top scientists in our field. Through this, I also have been invited to speak in spectacular place as like Europe, China and Australia. It will always be one my most memorable experiences that has made my life rich in the treasure of friends.
