Anthony Perk, 26, believes he is a woman after having a large malignant tumor that had spread to an estimated 53% of his brain and which had to be urgently removed.

Doctors warned Perk before the operation that removing half of his brain could lead to severe impairment of his brain could lead to severe impairment of his cognitive abilities and dramatically change the way his brain functioned but that the operation would save his life.

Since the operation, Perk now believes his thought patterns and brain functions have changed his personality into that of woman’s.

“I start crying for no reason at all, and act in completely irrational ways but the worst is my driving. I’m afraid I’m going to kill someone every time I get into my car,” Perk told reporters.

Dr Sacha Brezinsky at the lowa clinic for Neurological and Spinal Surgery Department Claims that his patient is producing abnormally high levels of estrogen since the operation which could explain the physiological and personality changes.

“I used to think that all women were crazy but now my brain functions like that of a woman’s, I can definitely tell you that they are all crazy,” Perk said laughingly.

Perks girlfriend of 5 years Alexandra Niles, has also noticed profound changes in her boyfriend’s personality.

“He used to be really mellow, but now he constantly keep nagging people all the time for the stupidest reasons. When the dishes are dirty, he just goes insane” said Niles

Although Niles admits she has to adapt to her boyfriend’s mood swings and erratic behaviour, she says she doesn’t mind that he now prefers to dress up as a woman.
