Swedish scientists are struggling to explain a rise in cases of hypospadias, a condition that causes baby boys to be born with deformed penises.
A 40-year study conducted by researchers at Stockholm's Karolinksa Institute found that incidences of hypospadias in babies born after 1990 jumped significantly from 4.5 boys out of every 1,000 to eight per 1,000.
The scientists said that they had taken into account factors such as low-birth weight that could be linked to the condition, but still could not explain the rise, The Local reported.
Hypospadias means the urethral opening is abnormally placed and can affect urination and sexual function later in life.
Lead researcher Dr Anna Skarin Nordenvall told Dagens Medicin newspaper that an unknown factor could be behind the deformities.
She said that scientists could not rule out the theory that chemicals - specifically environmental agents known as endocrine disruptors - could be responsible for the trend.
Endocrine disruptors, which are mostly man-made, can be found in pesticides, plastics and various household products.

Firefighters continue a battle a wildfire that has burned for five days in central Sweden.
The fire has burned 150 square kilometres (60 square miles) of forested land and killed at least one person.
A thousand people have been evacuated from villages and towns in the area threatened by the fire.
Amateur video uploaded online on Monday showed plumes of thick white and black smoke rising over a forest in Virsbo locality, in Vastmanland province.
Italy and France have sent firefighting planes to help contain the blaze, one of the biggest forest fires in Sweden in recent decades.
Police say the badly charred body of man in his 30s was found in the area earlier today.
Another man was taken to a hospital with serious burns.
It is unclear what sparked the fire but authorities say unusually hot weather and dry conditions are fuelling the flames.
Swedish police have detained a man who tried to enter the cockpit on a flight from Dubai to Stockholm.
Onboard staff handcuffed the man during the Emirates flight today and handed him over to police when the plane landed at Arlanda airport in Stockholm, police spokesman Albin Naverberg said.
Officers held the man on suspicion of preparing aircraft sabotage after interviewing the plane's crew, Naverberg added.
Henrik Kelfve, spokesman for airport operator Swedavia, confirmed that a male passenger had tried to enter the cockpit on the Emirates' flight.
Swedish tabloid Expressen reported that a man had shouted that he had a bomb, about an hour after the departure from Dubai.
Nine women in Sweden have successfully received transplanted wombs donated from relatives and will soon try to become pregnant, the Associated Press has revealed.
The women were born without a uterus or had it removed because of cervical cancer. Most are in their 30s and are part of the first major experiment to test whether it's possible to transplant wombs into women so they can give birth to their own children.
The transplants began in September 2012 and the donors include mothers and other female relatives of the recipients. They are intended to be temporary, just to allow childbearing.
There have been two previous attempts to transplant a womb — in Turkey and Saudi Arabia — but both failed to produce babies.
Fertility experts have hailed the project as significant, but they stressed that it's unknown whether the transplants will result in healthy babies.
Sweden's foreign minister Carl Bildt has said he believes Syrian forces are to blame for the alleged chemical attack, based on the evidence he has seen.
Writing in Swedish on his official blog, Mr Bildt said:
I have a hard time coming to any conclusion other than that a deadly chemical substance has been used in the attack carried out by the regime's forces between Tuesday and Wednesday on this opposition-controlled area.
He also said that if such an attack was confirmed by UN inspectors, he believes it would force Russia to reconsider its position and perhaps result in stronger action by the UN Security Council.
British heptathlete Louise Hazel told ITV News she is unconvinced by pole vaulter Yelena Isinbayeva's attempt to distance herself from "discriminatory" remarks about Russia's anti-gay law.
The spokesperson for the Russian pole vault world champion Yelena Isinbayeva has told ITV News the athlete is not against gay people and that her comments have been misunderstood.
The journalists twisted her words, she didn't say she was anti-gay.
Yelena's a sportswoman, she's not a politician.
She's only against gay propaganda, not against gay people - they can live how they want.
We have no idea what is going on in the UK so we have no comment about her resigning [from her role as youth Olympic ambassador for the Winter Olympics in Sochi in 2014.]
Russian pole vaulter Yelena Isinbayeva has said she may have been "misunderstood" when she made comments condemning homosexuality, according to the Associated Press.
The two-time Olympic gold medalist appeared to back off her comments at the World Championships, after criticising two Swedish athletes who protested against the Russian law banning the promotion of homosexuality.
She said: "English is not my first language and I think I may have been misunderstood when I spoke yesterday.
"I respect the views of my fellow athletes and let me state in the strongest terms that I am opposed to any discrimination against gay people."
