Behind all the Hollywood glitz and glamor are real life struggles. And Jennifer Aniston just revealed a big one. I'm Nikki. And this is quick and dirty. Like millions of women, Jen was having trouble getting pregnant and tried to conceive via in-vitro fertilization or IVF. The 53 year old Star of Friends and We're the Millers came forward with stories of her challenges. In an interview with Allure magazine stating, It was really hard. I was going through IVF, drinking Chinese teas, you name it. I was throwing everything at it. I would have given anything if someone had said to me, Freeze your eggs. Do yourself a favor. You just don't think about it. So here I am, and the ship has sailed. Aniston didn't specify exactly when she went through the IVF treatment, but this process is common for advanced maternal age pregnancies, which are defined as pregnancies 35 and older.

Conceiving a child later in life is no foreign concept to many celebrities, including Halle Berry, Celine Dion and Nicole Kidman, who were all in their forties when they welcomed children into the world. It's not just older women who use IVF treatment either. 30 year old model and actress Olivia Culpo recently announced her difficulty with endometriosis and how it may complicate her potential future as a mother.

IVF can be a long and exhausting process, and for those looking to conceive later in life, or for those who have fertility issues such as endometriosis, freezing eggs and relying on IVF procedures may be your best bet. A woman's fertility sharply dips after reaching the age of 35, but more babies are born in this age bracket than ever before.
