Dr. Resnick and colleagues assessed 788 participants in the cognitive function arm of the TTrials but focused on the 493 participants who were classified as having age-associated memory impairment with a confirmation of both subjective and objective indicators of cognitive decline. The authors detected no significant effect after 1 year of testosterone treatment on either the primary outcome of verbal memory, as measured by delayed paragraph recall or on any of the secondary outcomes of visual memory, executive function, and spatial ability.1

Hacking your testosterone influences everything from body composition to energy levels to mood. It’s easy to eat more butter; it’s hard to visit a doctor and get tested, but that’s what I recommend: know your levels. If you’re 25, you’ll know what your target is when you’re 35. By the time you’ve noticed symptoms of low testosterone, it’s too late to get your “normal” measurements!
The study population in these TTrials included men aged 65 years or older with mean morning serum testosterone concentrations of 275 ng/dL or less and symptoms of impaired sexual function, physical function, or vitality. These trials were placebo-controlled and the testosterone treatment group received 1% testosterone gel at variable doses adjusted to maintain plasma testosterone at levels normal for young men (500-800 ng/dL).
Andy – If you take testosterone, your hypothalamus will notice an abundance of testosterone in your system and will instruct your pituitary gland not to send LH and FSH to your testicles. If you’re testicles are not receiving these two hormones, they will stop making testosterone. If you quit testosterone call turkey, you will likely fall back to your baseline level fairly quickly. There is a protocol however to get back to your normal production much quicker should you choose to quit therapy.
Hello..was prescribe andro gel 1.62 for about 2 years..borderline low..At time 54 year old now 57..a year ago switched doctors..new doctor would not prescribe andro gel..without me stopping use and then being checked after 6 months..it’s been a year..by the way felt great while on it much more energy. .did notice some hair receding. .but felt stronger..my question is..by using andro gel ..did I turn off my body’s natural ability to make testosterone as using andro gel..if so what do I need to do too turn my body on if my doctor does not renew therapy. .by way the past without andro gel…little too no energy..weight gain of 40 lbs..especially around the belly..thank you for your time and reply

In accordance with sperm competition theory, testosterone levels are shown to increase as a response to previously neutral stimuli when conditioned to become sexual in male rats.[40] This reaction engages penile reflexes (such as erection and ejaculation) that aid in sperm competition when more than one male is present in mating encounters, allowing for more production of successful sperm and a higher chance of reproduction.
Testosterone is an androgen hormone produced by the adrenal cortex, the testes (in men), and the ovaries (in women). It is often considered the primary male sex hormone. Testosterone stimulates the development of male secondary sex characteristics (like body hair and muscle growth) and is essential in the production of sperm. In women, testosterone plays a role in egg development and ovulation.
For example, in February 2017, scientists reported on trials involving men over age 65 who had low testosterone due to aging. Each trial included a different number of men depending on the subject of the research. Roughly half of the participants received testosterone therapy for a year; the rest underwent a placebo treatment. The researchers discovered the following:
In a subsequent study of 345 men with normal PSA and low testosterone, we found the cancer rate was similar: 15%. And we had a large enough group to look at the impact of testosterone on cancer risk. For men whose total testosterone or free testosterone value was in the lowest third, the odds of having a positive biopsy were double the odds in the rest of the men. That’s the first evidence that low testosterone may be an independent predictor for the development of prostate cancer.
There are two keys to incorporating fat in your diet: getting enough fat, and getting the right kinds of it. A study from 1984 (done, no doubt, with Big Brother watching) looked at 30 healthy men who switched from eating 40% fat (much of it saturated) to 25% fat (much of it unsaturated), with more protein and carbs to make up the difference in calories. After 6 weeks, their average serum testosterone, free testosterone, and 4-androstenedione (an important hormone for testosterone synthesis) all dropped significantly [6]. I think getting 40% of your calories from fat is too little – I recommend 50-70% of calories from fat, or even more in some cases.
If you live in or near the Pittsburgh, PA area, are over 35 and want a free blood test and Physician Exam to see if you are eligible for prescription testosterone, Arimidex and a DHT blocker. Additionally, you may have adult onset gH deficiency. By middle age, most people lose up to 85% of their endogenous gH production. You may also be eligibility for sermorelin, a gH releasing hormone. contact us at ReGenesis HRT. 724-510-0024

In 2003, an Institute of Medicine panel concluded that there was insufficient evidence supporting the benefits of testosterone in older men and recommended further research. Consequently, in 2010, the National Institute of Aging, which is part of the NIH, launched the Testosterone Trials (T Trials) to figure out whether testosterone can help with symptoms associated with low levels of testosterone secondary to older age (i.e., symptomatic hypogonadism).
I think we’ll also find out in five years that there very well may be general health benefits of having normal testosterone compared to low testosterone. There are growing data for all-cause mortality that men who have low testosterone die earlier than those who have normal testosterone. A study by the Veterans Administration reported about a year ago showed low testosterone levels were associated with a dramatically increased mortality rate. It’s hard to know why that is, but I think we’ll be focused on that in the coming years.
I have been on testosterone injections for about six months now. My urologist has me taking 50mg a week. I noticed that when I take the injection my normal resting heart rate is about 61 beats a minute, on the day of the injection it goes up to about 84 BPM. I also notice a tightness in my chest/esophagus area for about 24-48 hours and than it subsides. I have also noticed it appears to make my eyes water on the day of the injection. I have gotten off the injections because that is the obvious thing to do, but the dillema is than my personal life with the wife suffers. I am in great shape and work out all the time. Is there anything you can recommended I do to mitigate the increased blood pressure and increased heart beat? My last blood test showed normal except my estrogen was right at the recommended max but still with in limits. Any advice would be appreciated.

A couple years ago I was having a problem with my thighs burning when walking up stairs. I noticed the muscles in my legs looking smaller. So I had my doc to check my T levels , and it was under 100. So she started me on testosterone injections weekly 200mg . After several injections I felt great , muscles in legs came back , lots of energy everything good . Leveled out at 3 injections a week 100mg , had a T level of 550 . So I go in for my scheduled injection and they tell me there out of testosterone . I might mention, this is a health care facilility that gives financial assistant if needed. And they have 3 or doctors and a nurse practitioner, which was who I was seeing . So I went on to check back often and got the same reply , were out of supply . So finally after months of the same , I gave up . I started loosing wait and my nerves got bad . Was having panic attacks etc. but I was coming off Prozac at the same time so I blamed it all on that. I was so bad with my nerves I ended up in the ER while on vacation . Doc there put me on a med for stress which I’m still using . After close to a year I checked back with the place I was getting TRT and they were resupplyed with testosterone. So I started back up because of low sex drive and ED. My first injection of 200mg was just short of a Marical , nerves felt great ED gone , had a sex drive , lot of energy . Then after 7 days or so all gone bad nerves started back up . He had me scheduled for anouther injection in 4 weeks 100mg . I went in for injection and after a couple days started feeling a little better . Then same thing as before about 7 days later nerves and everything else as before got worse . 3 weeks later I finally got a appt. with this different doc then I use to have . Told him the problems I was having , which included a horrible down mood , no energy . He decided to start injections every 2 weeks and upped the dose slitley. It’s been 5 days and already noticing ED problem reaccuring . He’s worried about the threat of prostate cancer. And doesn’t want to add any more injection to the schedule. I guess I’m going to have to start seeing the nurse practitioner who seemed to be more liberal and informed about TRT. I feel once a week injection is what it will take to get feeling good again. I’m 57 now with good health . Just need to get my T level on track with a doctor that will listen to how his patient is feeling . My last T level was at 365 . I failed to mention before I started the injections I was on androgel Dailey , 5 pumps a day . Then he gave me the injection of 200mg test . That’s when I felt fantastic for about a week or so . Then down hill . And I wanted to switch because the injection just seem so much better and they are . I noticed a big difference.

Longjack, also known as Tongkat ali and pasak bumi, is a shrub hailing from Southeast Asia purporting to improve libido. It’s gaining traction in the scientific community for potentially increasing testosterone levels, and researchers at South Africa’s University of the Western Cape found that longjack improved testosterone levels and muscular strength in physically active seniors (a population with typically low testosterone).
The other component of that study is that the subjects ate much less saturated fat. Saturated fats are common in meat, butter, and coconut products, and they’re crucial for your body to function. Saturated fats keep the integrity of your cell membranes, and if you limit carbs and/or do Bulletproof Intermittent Fasting, saturated fats become a phenomenal source of energy for your brain.
