Marissa Mayer, the new CEO of Yahoo (Nasdaq: YHOO), the No. 3 search engine, gave birth to a son on Sunday, her spouse, Zach Bogue, announced.

Details, including a name, height and weight, weren’t disclosed. Mayer, 37, disclosed her pregnancy and plans to take a brief maternity leave when she was recruited from Google (Nasdaq: GOOG), the No. 1 search engine, to the top job at Yahoo in July.

“We couldn’t be more excited,” Bogue said in an email announcement. Mayer is among a handful of female CEOs of technology companies, including Virginia Rometty, who became chairman as well as CEO of International Business Machines Corp. (NYSE: IBM) on Monday, and Margaret Whitman, CEO of Hewlett-Packard Co. (NYSE: HPQ).

Shares of Yahoo, of Sunnyvale, Calif., fell a nickel to $15.93 in midday Monday trading.
