US federal regulators said Friday they were investigating products containing testosterone after recent studies suggested a higher risk of strokes and heart attacks in men being treated with the hormone.
The Food and Drug Administration stressed, however, that it has “not concluded that FDA-approved testosterone treatment increases the risk of stroke, heart attack or death.”
“FDA is providing this alert while it continues to evaluate the information from these studies and other available data,” it said in a safety alert, referring to two related studies.
Patients undergoing testosterone therapy should not stop their treatment without consulting their physician first, the FDA recommended.
Health care professionals were also asked to consider whether the benefits of FDA-approved testosterone treatment were likely to outweigh the possible risk of treatment.
The announcement followed publication of a study on Wednesday by the PLOS ONE science journal suggesting that men aged 65 and older being treated with testosterone were twice as likely to suffer heart attacks in the month after they began treatment.
The study, which analyzed findings from 56,000 men in the United States between 2008 and 2010, also revealed a sharply increased risk among younger men with a history of heart disease.
In November, a separate clinical study in the Journal of the American Medical Association reported that older men using testosterone, including many with a history of heart problems, faced a 30 percent greater chance of mortality, heart attack or cardiovascular event.
A US government-funded study to determine whether men using testosterone gel to build muscle and increase strength was halted in 2009 after the high rate of cardiovascular problems related to the treatment.

Disney heiress who went undercover to Disneyland ‘livid’ at conditions and pay
Heiress Abigail Disney went to one of her family's resorts to see conditions for workers herself and was disgusted by what she saw.
In comments to Yahoo News podcast "Through Her Eyes," Disney described how she went to Disneyland in California undercover and found that workers at the resort were treated poorly—and underpaid.
"Every single one of these people I talked to were saying, 'I don't know how I can maintain this face of joy and warmth when I have to go home and forage for food in other people's garbage,'" said Disney.
Ex-Peru president wanted for corruption arrested in the US
Former Peruvian president Alejandro Toledo was arrested in the United States Tuesday to face extradition to his home country on corruption charges, authorities in the South American nation said.
The 73-year-old is suspected of involvement in the sprawling Odebrecht scandal in which the construction giant paid hundreds of millions of dollars in bribes throughout the continent to secure huge public works contracts.
The Peruvian attorney general's office announced on Twitter that Toledo "was arrested this morning for extradition, in the United States."
Toledo has been formally charged with receiving a $20 million payment from Odebrecht to grant it the tender to build the Interoceanic Highway that links Peru with Brazil.
Comic-Con mines past for future hits on 50th edition
A smorgasbord of sequels, prequels and reunions from "Terminator" to "Game of Thrones" awaits thousands of misty-eyed comic book geeks and sci-fi nerds descending on San Diego this week for the world's largest celebration of pop culture fandom.
