A Filipino man has cut off his penis in an attempt to prove his fidelity to his estranged wife.

The man, from Malasiqui, then wrapped it in newspaper and put it through a window of her parent's house.

He shouted at the woman: "So you will not suspect I am courting another girl."

The severed three-inch penis is now with police, who have sought the help of an embalmer to preserve it in a bottle.

The couple have been estranged for three years after the woman's parents persuaded her to live with them.

They said the man had been incapable of looking after her and their two children, as he was unemployed.

The man still hasn't been located, reports the Philippine Star.
