Marissa Mayer, New Yahoo CEO, Is Pregnant

— -- Marissa Mayer, the new CEO of Yahoo as of Monday, is pregnant.

After announcing she would be leaving Google after 13 years, the 37-year-old's whirlwind day continued as she told Fortune she was expecting a baby boy Oct. 7.

"He's super-active," Mayer said. "He moves around a lot. My doctor says that he takes after his parents."

While this may seem like an overwhelming day for Mayer, she's known about her pregnancy since January. When the Yahoo recruiter first contacted Mayer June 18, she was well-aware that she would soon be a new mother. She told Yahoo's board about her pregnancy in late June.

According to All Things D, Mayer's pregnancy was not an issue to the company's board. Yahoo's decision reflects a change in a business environment once inhospitable to mothers and women expecting children.

"It was not part of the consideration," said an anonymous person familiar with the situation. "Like every other professional woman, she has to weigh all the factors in doing her job and having a family."

Mayer also expressed that she was pleased the Yahoo board was not concerned, telling Fortune their actions "showed their evolved thinking."

And as far as maternity leave goes, don't expect Mayer to be out of the office for long. The new CEO plans to return to the office after a few short weeks and will be working throughout her time off. Yahoo's scheduled September board meeting will be in Sunnyvale, Calif., rather than New York, to accomodate for the expecting mother-to-be.
