Doctors in India are baffled by a teenage boy who appears to have started having periods.

Tarak, from Kalna in West Bengal’s Burdwan district, has reportedly been experiencing menstrual symptoms for a year.

The 15-year-old bleeds from his penis in the second week of every month, reports the Hindustan Times.

The youngster is also said to suffer from nausea, stomach ache and mood swings.

Sudip Mondol, a local physician, said: “The boy has male organs but he has feminine attributes. If tests of his blood samples prove the presence of ovum, this would be a rare medical case.”

Pradip Mitra, of the West Bengal Gynaecological Society, said: “The presence of female functional endometrial in a male prostate gland can cause this type of abnormality.”
