A British man was shocked to the bone when he was told by his doctors he could get pregnant and give birth.
A scan revealed the unidentified 37-year-old had a working set of female reproductive organs, giving him periods, premenstrual tension and the possibility of pregnancy.
His condition was unveiled when he was sent for an MRI scan after noticing blood in his urine.
In an interview with The Sun Newspaper he said "The diagnosis came as a bombshell. I’m just a regular, red-blooded guy."
"I was shocked when the consultant said I had a fully functioning set of women’s reproductive organs, and I was even having periods."
The man, who is from Lancashire and in a relationship with a woman, added: "I’ve never seen myself as anything but an ordinary bloke who has a normal sex life.
His doctors believe he has persistent Müllerian duct syndrome (PMDS), a rare conditions where the man has external male genitalia and internal female reproductive organs.
According to The Mirror report, Some doctors have now urged him to have the organs removed.
He added that as a child he went through puberty normally, but in his teens and 20s he suffered an ache after sex and noticed blood in his urine.
Tests for bladder cancer came back negative, so he was given an MRI scan.
His condition may explain the blood, potentially a result of his periods, as well as the post-sex ache being caused by PMT.
He even revealed that his ache after sex was caused by PMT.
One of the reasons he spoke out is that he aims to help others with the condition, adding: "I can't believe I'm the only person with this. And I hope any other man with similar symptoms will get checked out."
An upcoming DNA test will reveal his full gender balance, but whatever happens he says he will continue to live as a man - even if he is mostly woman.
The condition has also been reported in dogs.
