The 37-year-old actress, who plays Serena Southerlyn on the NBC crime drama, made her comments on a blog posted on People magazine's website. Rohm and her fiance Ron Anthony welcomed Easton, their first child, in April 2008.
"It is devastating when you simply can't do it the natural way and your body can't function as you believed that it would during your whole young adult life," Rohm says in her blog. "Of course, my closest inner circle knows about my choice to do IVF, and whenever I meet a woman who is struggling and lost in her pursuit of a natural pregnancy, I am very forthcoming."
"It's mutually soothing to share this personal experience," she added. "We all need comfort and support when we are experiencing personal challenges."
Rohm said she tried IVF twice and was inspired by actress Nicole Kidman's story about her own fertility problems.
"I was grateful to Nicole when I watched her in an interview from Australia," Rohm said. "I was grateful to her for trying to set us free from the judgment that can be laid upon women who cannot conceive naturally. Also, for helping me to recognize the judgments I had put upon myself. It's not easy to be that woman and to feel a bit broken in silence."
In late December of 2010, Kidman and her husband Keith Urban welcomed a daughter, Margaret, who was born to a surrogate mother. Kidman said she was unable to get pregnant when she and Urban decided to have another baby following the birth of their first daughter, Sunday, in 2008. Kidman also has two adopted children with ex-husband Tom Cruise.
