David Duchovny has entered a rehabilitation facility for sex addiction.
In a statement released by his lawyer, Stanton Stein, the actor said he did so voluntarily, adding: "I ask for respect and privacy for my wife and children as we deal with this situation as a family."
The actor's publicist, Flo Grace, confirmed the rehab report, which first appeared on People.com.
She and Stein both declined to elaborate further.
Duchovny, 48, plays a sex-obsessed character on the Showtime television series Californication, which earned Emmy nominations for casting and cinematography. The show's second season begins September 28.
Showtime had no comment on Thursday.
The actor appeared in the film The X Files: I Want to Believe earlier this year. He has been married to actress Tea Leoni since 1997. They have two children.
