Is testosterone replacement therapy the right thing for aging males?

A study suggests that exercise can reduce the risk of heart damage for middle-aged adults and seniors. According to the study, even those who are obese will benefit from physical activity. Wochit

Testosterone (T) is a naturally occurring hormone in men, and most of it is produced in the testicles.

At puberty, T production escalates, bringing about masculinizing changes in muscle mass.  also promotes sex drive, sperm and red blood cell production, bone mass and determines how men store body fat.

It can impact quality of life issues as well, like mood, energy and motivation.

Beginning at about age 30, T production begins to decline on average by about 1 percent per year, plummeting late in life. This causes all sorts of problems, including lack of sex drive, inability to sleep, loss of muscle and bone mass, increased belly fat, the list goes on. Reversing these symptoms and improving the quality of life is the reason T replacement therapy (TRT) clinics supervised by physicians have sprung up around the country.

Although it is considered a male hormone, women also produce a modest amount of T in the ovaries. After menopause, estrogen production declines, which alters the ratio of estrogen to T, explaining why women begin taking on some male characteristics, like storing more fat around the midsection, rather than on the hips, thighs and buttocks as occurs earlier in life.

TESTOSTERONE REPLACEMENT THERAPY

Is TRT a good thing? It can be when managed responsibly. If you are older, and your T level is very low and falls below the normal range, it makes sense to address it with TRT because it can negatively impact health, increasing risks associated with diabetes, obesity and osteoporosis. Low T also may shorten life, but this is controversial because when TRT raises T levels it has not been shown to extend life.

More is not always better, and many TRT clinics are viewed with suspicion because they advertise that it’s possible to feel like you are 25 years old again, even though you are decades older. Perhaps this is possible, but at what price, and if you are taking huge doses of T, could you be damaging your health?

Research studies in 2013 and 2014 indicated that TRT increased the risk of heart disease in men 65 and older, and in younger men with a history of heart disease. However, subsequent studies refute these findings and some show a deceased risk of heart disease. Another area of concern is an increased risk of prostate cancer, but this, too, is controversial. There does appear to be solid evidence that TRT can increase the risk of blood clots and stroke, plus sleep apnea, acne and breast enlargement.

All in all, some experts believe the benefits outweigh the risks, while others are more cautious because TRT hasn’t been around long enough or impacted enough men to draw meaningful conclusions. Time will tell. In the meantime, like most things in life, moderation is the best approach.

THE BOTTOM LINE

TRT has a place and can be beneficial if managed prudently. Just be careful of extreme approaches and promises that seem too good to be true. As for AS, there is no justifiable reason for athletes to be taking them. Ever!

Infertility in men could point to more serious health problems later in life

Leave a comment

Poor sperm quality affects about one in ten men and may lead to fertility problems. These men also have an increased risk of developing testicular cancer, which is the most common malignant disease of young males. And, even if they don’t develop testicular cancer, men with poor sperm quality tend to die younger than men who don’t have fertility problems.

Couples who can’t achieve pregnancy usually go to fertility clinics for treatment. At these clinics, emphasis is put on deciding whether the couple needs assisted reproduction or not, and, if so, to choose between different methods (such as IVF, IUI, or ICSI) for doing this. In most cases, these treatments lead to pregnancy and a live birth. So the problem seems to be solved. But if infertility is an early symptom of an underlying disease in the man, fertility clinics won’t pick it up.

Missed opportunity

Testicular cancer is easy to detect. In men seeking treatment for fertility problems, a simple ultrasound scan of the testes can reveal early cancer, so a life-threatening tumour can be prevented. If detected, 95% of all cases can be cured. But, unfortunately, testicular ultrasound scans are rarely performed at fertility clinics as the focus tends to be on sperm numbers and which method of assisted reproduction to use.

And testicular cancer is not the only threat to young infertile men’s health. Serious health problems, such as metabolic syndrome (high blood pressure, high blood sugar and obesity), type 2 diabetes and loss of bone mass are also much more common conditions among infertile men. These disorders are possible to prevent, but if left untreated often lead to premature death.

A possible culprit

At Lund University in Malmö, Sweden, we have – together with other research groups – made a number of studies focusing on the link between male fertility problems and subsequent risk of serious diseases. We cannot yet explain the causes, but testosterone deficiency is a strong candidate. My research team found that 30% of all men with impaired semen quality have low testosterone levels. And men totally lacking the hormone have early signs of diabetes and bone loss.

We recently conducted a study in which we investigated almost 4,000 men below the age of 50 and who had had their testosterone measured 25 years ago. We found that the risk of dying at a young age was doubled among those with low testosterone levels compared with men with normal levels of this hormone.

Although testosterone treatment may not necessarily be the best preventive measure, these findings makes it possible to identify men at high risk so that they can be advised about lifestyle changes, such as losing weight or quitting smoking – lifestyle changes that will help reduce the risk of developing type 2 diabetes, cardiovascular disease and osteoporosis.

A relatively high proportion of men get in touch with their doctor about infertility problems and, as they represent a high-risk group for some of the most common diseases occurring later in life, perhaps it is time to change the routines for managing them. With the knowledge we now have regarding these men’s health, the least we can demand from doctors is to identify those who are at risk of serious diseases after they have become fathers. This is cheap and only requires simple tests. It is no longer enough to just evaluate the number of sperm.

Bone Density, Anemia Improve With Testosterone in Low-T Men

Leave a comment

Study Highlights

  • Snyder and colleagues:
    • Study participants were men at least 65 years old with 2 serum testosterone results of less than 275 ng/dL.
    • Men were randomly assigned to receive testosterone gel with titration to maintain serum testosterone levels commensurate with those of a young man, or placebo gel. The treatment period was 12 months.
    • The main study outcome was BMD. Participants underwent BMD testing with quantitative computed tomography and dual energy x-ray absorptiometry of the spine and hip at baseline and at 12 months.
    • 211 men participated in the trial. The mean age of participants was 72.3 years, and the baseline mean testosterone level was slightly more than 230 ng/dL.
    • vBMD increased in the testosterone group by a mean of 7.5%, compared with an increase of only 0.8% in the placebo group (P <.01).
    • Measurements of hip trabecular and peripheral vBMD were also superior in the testosterone group vs the placebo group.
    • Testosterone appeared more effective in increasing trabecular vs peripheral BMD, and in improving BMD in the spine vs the hip.
    • 19 fractures were reported during the treatment year and 1 year after the treatment period, with no evidence of a difference in fracture rates in comparing the testosterone group vs the placebo group.
  • Roy and colleagues:
    • The study was conducted as a double-blind, placebo-controlled trial among men 65 years or older. All participants had a serum testosterone level of less than 275 ng/dL.
    • Men were randomly assigned to receive testosterone gel with titration to maintain serum testosterone levels commensurate with those of a young man, or placebo gel. The treatment period was 12 months.
    • There were 788 men in the study, of whom 126 were anemic, as defined by a hemoglobin level of 12.7 g/dL or lower. Approximately half of men with anemia had no known cause for anemia.
    • The main study outcome was the effect of testosterone therapy on hemoglobin levels among men with anemia.
    • The mean age of participants was 74.8 years, and the mean serum testosterone level among men with anemia was 222 ng/dL at baseline.
    • 54% of men with unexplained anemia who were treated with testosterone experienced an increase in hemoglobin levels of 1.0 g/dL or more, compared with only 15% of men with similar anemia treated with placebo (adjusted OR, 31.5; 95% CI, 3.7-277.8).
    • 58.3% of men treated with testosterone experienced resolution of their anemia, compared with 22.2% of men treated with placebo.
    • Testosterone also raised hemoglobin levels vs placebo among men with a known cause of anemia.
    • Hemoglobin levels increased past 17.5 g/dL in 6 men without anemia at baseline.

Clinical Implications

  • A retrospective cohort study by Cheetham and colleagues finds that testosterone therapy among men with evidence of testosterone deficiency is associated with lower risks for cardiac disease and cerebrovascular disease, even among men older than 65 years and those with preexisting cardiovascular disease.
  • Two new studies demonstrate that testosterone treatment can correct anemia and improve BMD among men with low testosterone levels at baseline.
  • Implications for the Healthcare Team: The current studies further demonstrate potential benefits of testosterone therapy among men with testosterone deficiency. Testosterone therapy was also associated with a lower risk for cardiovascular events in one study. Nonetheless, clinicians should continue to perform shared decision making regarding testosterone therapy and apply this treatment only among men with established testosterone deficiency.

Testosterone Does Not Appear to Increase The Risk For Cardiovascular Disease

Leave a comment

Testosterone replacement therapy does not appear to increase the risk for cardiovascular disease or thromboembolic events in middle-aged men.

In fact, the risk for a cardiovascular event was lower in men taking supplemental testosterone than in those who were not, said lead investigator Julian Hanske, MD, from Ruhr University Bochum in Herne, Germany, who collaborated on the study during a fellowship at Brigham & Women’s Hospital in Boston.

But physicians should know whether a patient suffers from obstructive sleep apnea before prescribing testosterone, Dr Hanske said here at the European Association of Urology 2017 Congress.

Cohort studies of the cardiovascular and thromboembolic consequences of supplemental testosterone have generally relied on sources such as the Surveillance, Epidemiology, and End Results Medicare database, which is limited to an older population, he told Medscape Medical News.

To get a better handle on the relative risks associated with testosterone replacement therapy in a younger population, Dr Hanske and his team searched the TRICARE American military insurance database, which covers all retired and active-duty military personnel and their dependents.

They looked for men 40 to 65 years of age treated for low levels of testosterone. Patients were excluded if they had a history of heart disease, thromboembolism, prostate cancer, or obstructive sleep apnea.

For the final cohort, 3422 men who took testosterone were matched with 3422 control subjects who did not by year of birth, then by date of first testosterone prescription, and then by race and baseline comorbidities.

The study outcomes were event-free survival and absolute risk for cardiovascular disease, thromboembolism or obstructive sleep apnea.

We have so many fears of testosterone replacement therapy.

Cardiovascular event-free survival was significantly better in the testosterone group than in the control group (P = .0085), and risk for coronary artery disease was lower in the testosterone group (P = .0082).

There was no difference in thromboembolic event-free survival between the testosterone and control groups (P = .0998).

These findings are reassuring, said session comoderator Raanan Tal, MD, head of the male infertility program at Rambam Medical Center in Haifa, Israel.

“We have so many fears of testosterone replacement therapy, and actually what they showed is that so many beliefs that we have cannot be supported,” he told Medscape Medical News.

“The fact that you don’t have an increase in cardiovascular events or thrombotic events is an important message — more important than the risk of increased obstructive sleep apnea,” he explained.

But the other comoderator said he thinks the findings would be more compelling if the investigators had used propensity-score matching or a similar statistical method to ensure a close case–control match.

“Age is a risk factor,” Andrea Salonia, MD, from the Vita-Salute San Raffaele University in Milan, pointed out. “The younger the patient, the lower the probability of having difficulties sleeping at night, and they did not adjust for that specific issue, or at least they did not find any kind of difference according to this specific variable.”

“At the same time, the number of patients they considered was amazing, and it is probably one of the most important studies in terms of the huge cohort they selected,” Dr Salonia told Medscape Medical News.

Dr Hanske, Dr Tal, and Dr Salonia have disclosed no relevant financial relationships.

Jane Fonda reveals testosterone is the secret behind her sex success at 73

Leave a comment

She has attributed her youthful looks to a healthy love life and given hope to millions by saying she had the best sex of her life at 71.

So it is something of a let down to find out that even sex symbol Jane Fonda needs artificial help.

The Barbarella star has revealed she took the male sex hormone testosterone from the age of 70 to boost her libido.

Miss Fonda said it made ‘a huge difference’.

Advising other women of a certain age how to pep up their love lives, three-times married actress, political activist and fitness guru said: ‘Here’s something I haven’t said publicly yet: I discovered testosterone about three years ago, which makes a huge difference if you want to remain sexual and your libido has dropped.

‘Use testosterone, it comes in a gel, pill or patch.’

Earlier this year, Robbie Williams shocked his legions of female fans by admitting he was injecting himself with testosterone to boost his sex drive.

Although testosterone is usually thought of as a male hormone, it is also made by women, but in much smaller amounts.

Levels drop off after the menopause, leading to some doctors prescribing testosterone alongside more traditional hormone replacement therapy.

It is relatively cheap, costing around £50 for six months’ supply and comes in patches, implants and gels.

But a reinvigorated love life can come at a cost.

Miss Fonda, now 73, and in a relationship with music producer Richard Perry, who is four years her junior, told the Sunday Telegraph: ‘I had to stop because it was giving me acne.

‘It’s one thing to have plastic surgery, but it is quite another to have adolescence acne. That is going too far.’

Two years ago, she created envy in millions of bedrooms by telling how she was having the best sex of her life, despite having had spinal surgery and boasting an artificial knee and a titanium hip.

She said: ‘How do I still look good?  I owe 30 per cent to genes, 30 per cent to good sex, 30 per cent because of sports and healthy lifestyle with proper nutrition and for the remaining ten per cent, I have to thank my plastic surgeon.

But I’m happier, the sex is better and I understand life better. I don’t want to be young again.’

More recently, she has devoted 50 pages of her new autobiography to explaining how couples can keep the passion alive long after the vigour of their youth has failed.

However, her use of testosterone has remained secret until now.

British experts welcomed the revelation.

Professor John Studd, of the London PMS and Menopause Clinic has been prescribing testosterone for women for 30 years.

He said: ‘It is not just about libido.  The benefits include more energy, more self-confidence, better mood and all of those things.’

He added that carefully balancing the dose should remove the risk of side-effects such as acne and excessive bodily or facial hair.

Dr John Stevenson chairman of the charity Women’s Health Concern, said: ‘Jane Fonda clearly thinks there should be no time limit to being sexually active, which is fine. Good for her.’

However, the Royal College of Obstetricians and Gynaecologists warns that the long-term consequences of the treatment are unknown.

THE TRUTH BEHIND TESTOSTERONE

Testosterone can be part of the hormone replacement therapy given to menopausal women.

Gels that are rubbed into the skin are the most popular.  But patches, creams and implants are also available.

Topping up levels of the hormone can give a woman in her 50s or 60s the libido of someone half her age, as well as boost energy and mood.

But too high a dose carries the risk of acne and greasy skin and hair.

‘Masculine’ side-effects such as excessive bodily and facial hair and a deepened voice are also possible.

Testosterone pills aren’t given to women but can raise cholesterol, increasing the odds of heart attacks and strokes.

The Royal College of Obstetricians and Gynaecologists urges caution when prescribing the libido-boosting treatment to women other than those who have had their ovaries removed.

It advises: ‘Testosterone replacement may be associated with adverse clinical and metabolic side effects and long-term consequences are unknown.

Effects of taking tadalafil 5 mg once daily on erectile function and total testosterone levels in patients with metabolic syndrome.

Leave a comment

We aimed to evaluate the efficacy of tadalafil 5 mg once-daily treatment on testosterone levels in patients with erectile dysfunction (ED) accompanied by the metabolic syndrome. A total of 40 men with metabolic syndrome were evaluated for ED in this study. All the patients received 5 mg tadalafil once a day for 3 months. Erectile function was assessed using the five-item version of the International Index of Erectile Function (IIEF) questionnaire. Serum testosterone, follicle-stimulating hormone and luteinising hormone levels were also evaluated, and blood samples were taken between 08.00 and 10.00 in the fasting state. All participants have three or more criteria of metabolic syndrome. At the end of 3 months, mean testosterone values and IIEF scores showed an improvement from baseline values (from 3.6 ± 0.5 to 5.2 ± 0.3, from 11.3 ± 1.9 to 19 ± 0.8 respectively). After the treatment, serum LH levels were decreased (from 5.6 ± 0.6 to 4.6 ± 0.5). There was significantly difference in terms of baseline testosterone and luteinising hormone values and IIEF scores (p < .05). Based on our findings, we recommend tadalafil 5 mg once daily in those men with erectile dysfunction especially low testosterone levels accompanied by metabolic syndrome.

Exploring the role of testosterone in the cerebellum link to neuroticism: From adolescence to early adulthood

Leave a comment

Highlights

  • Cerebellar volumes correlate inversely with neurotic personality traits in adolescents and young adults.
  • In males, higher endogenous testosterone levels is associated with lower scores on neurotic personality traits and larger cerebellar gray matter volumes.
  • Testosterone significantly mediates the relation between cerebellar gray matter and measures of neuroticism.

Abstract

Previous research has found an association between a smaller cerebellar volume and higher levels of neuroticism. The steroid hormone testosterone reduces stress responses and the susceptibility to negative mood. Together with in vitro studies showing a positive effect of testosterone on cerebellar gray matter volumes, we set out to explore the role of testosterone in the relation between cerebellar gray matter and neuroticism. Structural magnetic resonance imaging scans were acquired, and indices of neurotic personality traits were assessed by administering the depression and anxiety scale of the revised NEO personality inventory and Gray’s behavioural avoidance in one hundred and forty-nine healthy volunteers between 12 and 27 years of age. Results demonstrated an inverse relation between total brain corrected cerebellar volumes and neurotic personality traits in adolescents and young adults. In males, higher endogenous testosterone levels were associated with lower scores on neurotic personality traits and larger cerebellar gray matter volumes. No such relations were observed in the female participants. Analyses showed that testosterone significantly mediated the relation between male cerebellar gray matter and measures of neuroticism. Our findings on the interrelations between endogenous testosterone, neuroticism and cerebellar morphology provide a cerebellum-oriented framework for the susceptibility to experience negative emotions and mood in adolescence and early adulthood.
