More than 25,800 people were randomly assigned to one of four groups: one received 2,000 IU of vitamin D a day and a placebo, another took 1g of omega-3 fatty acids a day with a placebo, a third took both 2,000 IU of vitamin D and 1g of omega-3 a day, and the last group received two daily placebos. All volunteers took their assigned nutrients for approximately five years, and researchers logged everything from cancer diagnoses to major heart events including heart attack and stroke, as well as deaths from cancer and heart disease.
The people taking omega-3 fatty acids did not have a lower rate of heart events compared to the people taking placebo.
When they looked at the effects of vitamin D, they also found little difference among those taking the nutrient and those taking placebo when it came to overall heart disease and cancer measures.
While they don’t appear to do much overall in this study, fish oil seems to help specific groups of people and the researchers believe that vitamin D may simply take longer to have an effect on cancer rates and deaths.https://www.yahoo.com/news/fish-oil-vitamin-d-supplements-200048557.html
Key findings
Vitamin D supplementation
• Did not reduce risk of cancer
• Did not reduce risk of major cardiovascular events (heart attack, stroke, or cardiovascular death considered together)
• Appeared to reduce risk of cancer-related death
Omega-3 fatty acid supplementation
• Did not reduce risk of cancer
• Did not reduce risk of major cardiovascular events in the overall study population, but did reduce risk of these events by 19% in people with low fish intake
• Reduced risk of heart attack by 28%, when heart attack was considered separately from other cardiovascular events; the benefit appeared strongest in African Americans
For the first time, scientists have discovered a confirmed genetic link to erectile dysfunction.Link.
Researchers pinpointed a stretch of DNA where variations made it more difficult for men to perform as expected.
The finger of suspicion points to a gene called SIM1 which could be a target for new impotence treatments.
...
Besides having a potential influence on men’s erections, SIM1 is thought to play a role in brain development.
The scientists carried out the study by analysing the complete genomes, or genetic codes, of more than 36,000 American and 222,000 British men.
A search was made for genetic differences that occurred more often in men with a history of erectile dysfunction.
Variations in the SIM1 locus, the region of DNA containing the SIM1 gene, was associated with a 26 per cent increased risk of impotence.
The latest case report is the first study to show that color vision problems caused by retinal damage can result from a high dose of sildenafil citrate, and that excessive use of the drug may lead to long-term, possibly irreversible, vision problems.https://www.newsweek.com/man-took-so-many-erectile-dysfunction-drugs-his-vision-was-permanently-tinted-1150102
"People live by the philosophy that if a little bit is good, a lot is better,” Richard Rosen, lead author of the study and Director of Retina Services at NYEE, said in a statement. “This study shows how dangerous a large dose of a commonly used medication can be. People who depend on colored vision for their livelihood need to realize there could be a long-lasting impact of overindulging on this drug."
CONCLUSIONS: Among men aged 16-80 in the United States, we found increasing age, impaired sleep and elevated BMI is associated with low testosterone. It is important, therefore, that evaluation and treatment of reduced serum testosterone should also include improving sleep duration in combination with weight management.
Abstract
Neuromuscular impairment and reduced musculoskeletal integrity are hallmarks of spinal cord injury (SCI) that hinder locomotor recovery. These impairments are precipitated by the neurological insult and resulting disuse, which has stimulated interest in activity-based physical rehabilitation therapies (ABTs) that promote neuromuscular plasticity after SCI. However, ABT efficacy declines as SCI severity increases. Additionally, many men with SCI exhibit low testosterone, which may exacerbate neuromusculoskeletal impairment. Incorporating testosterone adjuvant to ABTs may improve musculoskeletal recovery and neuroplasticity because androgens attenuate muscle loss and the slow-to-fast muscle fiber-type transition after SCI, in a manner independent from mechanical strain, and promote motoneuron survival. These neuromusculoskeletal benefits are promising, although testosterone alone produces only limited functional improvement in rodent SCI models. In this review, we discuss the (1) molecular deficits underlying muscle loss after SCI; (2) independent influences of testosterone and locomotor training on neuromuscular function and musculoskeletal integrity post-SCI; (3) hormonal and molecular mechanisms underlying the therapeutic efficacy of these strategies; and (4) evidence supporting a multimodal strategy involving ABT with adjuvant testosterone, as a potential means to promote more comprehensive neuromusculoskeletal recovery than either strategy alone.
Purpose
Both testosterone deficiency (TD) and prostate cancer (CaP) have increasing prevalence with age. However, because of the relationship between CaP and androgen receptor activation, testosterone therapy (TT) among patients with known CaP has been approached with caution.
...
Conclusions
In the absence of randomized placebo controlled trials, our study supports the hypothesis that TT may be oncologically safe in hypogonadal men following definitive treatment or active surveillance for CaP.
Conflicting evidence exists for the long-term risk to fertility in men on TRT. Data abstracted from trials which sought to utilize TRT as a contraceptive found that sperm concentrations were suppressed to less than 1 x 106 ml-1 within 3.5 months. After discontinuation of testosterone, projected time to recovery (20 x 106 ml-1) was 67%, 90%, 96%, and 100% at 6, 12, 16, and 24 months respectively [9-11]. A recent publication evaluating men who presented to an infertility clinic with a history of TRT use found that only 70% of men achieved sperm recovery (total motile count >5 x 106) and that increased age and duration of TRT use were negative predictors of a patient’s ability to return to fertility [12]. This data is likely overestimates the long-term detrimental effect of TRT on fertility as no information regarding the patients’ ability to produce sperm prior to TRT is available. While a subset of these men was likely infertile prior to TRT therapy, this data serves as a caution to men and practitioners considering TRT within their reproductive years. While the absolute percentage of men who experience irreversible fertility loss after undergoing TRT is not known, there is a significant concern for this side effect in young men who may ultimately desire to father a child.
Cataceous i heard that men naturally produce tiny amounts of Human chorionic gonadotropin (HCG) in their testes, so it's just boosting our Natural supply, can you confirm this is true? i know for fact of course Pregnant Women produce H.C.G absolutely. But i heard men make small Tiny amounts in Testicles too. Did you hear of this before?
Taken from LiveStrong.com Article here https://www.livestrong.com/article/247492-what-is-a-normal-hcg-level-in-males/QuoteMale hCG levels are normally less than 5.0 mU per ml. Human chorionic gonadotropin is a hormone that is most often associated with pregnancy in women. However, both males and nonpregnant females produce low levels of hCG throughout their lives as well
What's more, any protective health effects of alcohol were offset by the drink's risk, including strong links between alcohol consumption and the risk of cancer and injuries such as car accidents.
"Our results show that the safest level of drinking is none."
The study found that moderate drinking was, in fact, protective against ischemic heart disease. But this benefit was outweighed by the health risks of alcohol.
