The director general of the internet portal Yahoo, Marissa Mayer, who announced her pregnancy shortly before taking the reins of the group in July, gave birth to her first child, a son, her husband announced in the social network Twitter.

"The small Bogue was born last night. The Mom and the baby are fine and we couldn't be more excited", wrote Zachary Bogue on Twitter.

Mayer caused a stir when it announced that after their pregnancy did not intend to take more than 'some weeks' maternity leave and that would not work during this time.

Mayer, 37, has been married to Bogue since 2009 and took over Yahoo!, after a career of 13 years at Google, last July in an attempt to relaunch the Internet company, which is in difficulties for four years.
