Study indicates correlation between regular ibuprofen use, male infertility

The study reveals that persistent ibuprofen use may lead to compensated hypogonadism, which can lead to infertility, erectile dysfunction, depression and loss of bone and muscle mass in males, among other symptoms.

New research shows that the use of common over-the-counter analgesics may contribute to male infertility, a problem that approximately 7 percent of men in the United States face.

A study published earlier this week in Proceedings of the National Academy of Sciences revealed that persistent ibuprofen use may lead to compensated hypogonadism, which can lead to infertility, erectile dysfunction, depression and loss of bone and muscle mass in males, among other symptoms.

Time reported that, of the 31 male volunteers in the study, 14 took two 600 milligram doses of ibuprofen daily for six weeks — an amount many athletes take to ease aches and pains — while others were given placebos.

Both groups of men were subjected to blood tests and hormonal analysis throughout the course of the study. Two weeks of ibuprofen use led to higher blood levels of luteinising hormone (LH), which regulates androgen production. After 44 days, LH levels soared even higher. These increases were not met with increased testosterone production, resulting in a low testosterone to LH ratio, a sign of hypogonadism.

Unexpected hormonal fluctuations were also observed, portending wide-ranging consequences of hypogonadism.

Researchers subsequently tested the effect of ibuprofen on testicular functionality using samples taken from organ donors. When exposed to similar amounts of ibuprofen, the samples produced less testosterone after only 24 hours. The researchers found a positive correlation between the level of exposure and the negative side effect. Their work also revealed that gene expression associated with converting cholesterol to steroidal hormones was impaired.

An earlier manuscript by the study’s lead author revealed that boys born to consumers of ibuprofen during the first trimester of pregnancy may have impaired testicular development, further suggesting that ibuprofen adversely impacts male fertility. (afr/kes)

President of Iran Declares End of ISIS

President Hassan Rouhani of Iran on Tuesday declared the end of Islamic State in an address broadcast live on state TV. A senior commander of Iran’s Revolutionary Guards, Maj.-Gen. Qassem Soleimani, also declared the end of Islamic State in a message sent to the country’s supreme leader Tuesday which was published on Sepah News, the news site of the Guards. Videos and pictures of Soleimani, who commands the Quds Force, the branch of the Guards responsible for operations outside of Iran’s borders, at frontline positions in battles against Islamic State in Iraq and Syria have been posted frequently by Iranian media in recent years.

The Revolutionary Guards, Iran’s most powerful military force which also oversees an economic empire worth billions of dollars, has been fighting in support of S...

EPL: Kelechi Iheanacho might be available for sale in January – Leicester City boss, Puel

Leicester City manager, Claude Puel, has hinted at the possibility of selling Nigeria star Kelechi Iheanacho four weeks before the winter transfer market opens for business. The Foxes have six strikers in the first team consisting of Iheanacho, Vardy, Ahmed Musa, Slimani, Okazaki and Ulloa, and the former Man City starlet has found game time hard to come by after making only two starts in the Premier League from a possible fifteen. Speaking to Leicester Mercury, Puel said: “Kelechi had an injury and for the moment, we have competition. “I am happy with Jamie for example. Kelechi or other players cannot play on the side. “It’s difficult for them, but for me also to manage all these players because we have six strikers so there is no place for all the players.” Iheanacho penned a five-year contract with Leicester City in the summer for a fee in the region of 25 million pounds.

Tech How Alibaba turned an obscure, made-up Chinese holiday into a $17.8 billion shopping extravaganza that's bigger than Black Friday

Alibaba raked in over $8 billion in sales in the first hour of its made-up marketing holiday, "Singles Day." Singles Day has its roots in an obscure Chinese holiday for students who had not married yet. Alibaba CEO Jack Ma capitalized expertly on the holiday, and now, Singles Day dwarfs traditional American shopping holidays like Black Friday, and is much larger than Amazon's "Prime Day." Alibaba turned Singles Day, the Chinese holiday for the single-set, into a huge economic opportunity through a savvy marketing blitz. The company raked in well over $8 billion during the first hour of this year's sale, largely through its online shopping platforms, Taobao.com and Tmall.com as well as a glitzy gala. Students at Nanjing University first celebrated Singles Day in 1993 as an appreciation of, you guessed it — being single. They picked November 11 (11/11) as an ode to the loneliness of the number one. But Single’s Day was never meant to be a somber aff...
