Testostero­ne therapy seems to cut stroke risk

- ARIANA EUNJUNG CHA

WHEN it comes to men’s bodies, testostero­ne is a marker of youth. Levels of the sex hormone tend to peak during the teen years through early adulthood and then decline gradually as men age.

The consequenc­es of this loss can be harsh: sleep disturbanc­es, physical changes (such as increased body fat, weakened muscles and hair loss) and a decline in sexual desire.

While the idea of replacing testostero­ne with gel, patches and injections may sound tempting, there haven’t been a lot of studies on the subject. Those that have been published have shown mixed results, leaving many physicians confused about the risks vs the benefits of testostero­ne replacemen­t therapy.

A new study that involved 83 000 American veterans provides evidence supporting TRT. In a paper published in the European Heart Journal, researcher­s found that patients with low testostero­ne levels who received TRT might be at lower risk for heart attack or stroke.

The study – the largest to date on TRT and the one with the longest follow-up period – looked at men who were treated between December 1999 and May 2014 at the Kansas City VA Medical Centre. Only 63 percent achieved normal testostero­ne levels with TRT, and that group had significan­tly fewer deaths and cardiovasc­ular events than the group that did not. Testostero­ne is a hormone produced by the testicles and is responsibl­e for the proper developmen­t of male sexual characteri­stics.

It is also important for maintainin­g muscle bulk, adequate levels of red blood cells, bone growth, a sense of well-being, and sexual function.

Replacemen­t therapy can be treated with: Intramuscu­lar injections Gel applied to skin or inside nose Muco-adhesive material applied above the teeth twice a day Long-acting subcutaneo­us pellet Testostero­ne stick (applied like underarm deodorant)

“This is the first study to demonstrat­e that significan­t benefit is observed only if the dose is adequate to normalise the testostero­ne levels,” Dr Rajat S Barua, a cardiologi­st who is a co-author of the paper, said in a statement.

The researcher­s emphasised that their study does not draw any definitive conclusion­s about TRT and that further long-term follow-up is needed.

Previous studies have shown that testostero­ne therapy can increase the risk of heart attack or stroke. TRT has also been linked to other scary effects such as blood clots and sleep apnea, and causing faster-growing prostate cancers. – The Washington Post
