The boycott - sparked by Kenya's political deadlock - ended this week

A Kenyan man has sued activists who urged women to deny their partners sex for a week as a protest against the country's political impasse.

James Kimondo told reporters outside the Nairobi High Court his wife had observed the boycott and caused him "anxiety and sleepless nights".

"I have been suffering mental anguish, stress, backaches, lack of concentration," he said.

It is unclear how many women joined the strike, which ended on Wednesday.

A group called the Women's Development Organisation called for the boycott as a means of forcing political leaders to put their rivalry aside to work for the common good.

The wife of Kenyan Prime Minister Raila Odinga endorsed the move, telling the BBC that political leaders were neglecting the needs of "the common person".

In court on Friday, Mr Kimondo said through his lawyer that his wife, Teresia Wanjiku, had denied him his conjugal rights.

He is seeking undisclosed "general damages" from the organisers of the boycott, on the grounds that it "interfered with his happy marriage", the Kenyan broadcaster KBC reports.
