  •  
    Study finds that low free T and low Total T were associated with decline in desire, ED and activity versus none with Estradiol and SHBG in older men.  The difficult issue is the threshold of "low T".  The definition of "low T" is not uniform and varies with age.  Thus baseline evaluations and correlation with symptoms, metabolic dysfunction must be done.

Pimples In The Penis - What Is The Cause? - 1 views

  •  
    The penis gets pimples, white or red items make men worried because they don't know the cause. In most of the causes of penile acne, the group of causes of sexually transmitted diseases is the most dangerous. Genital skin is very sensitive, especially in the penis. Only a small change can cause abnormal symptoms such as tumors, irritation, irritation and discomfort. Men need to understand the reasons for effective prevention and treatment. Group of allergy causes: Men with acne in the penis due to local allergies, for example, the penis skin has been exposed to "strange" substances from poor quality condoms. In addition, wearing underwear that is too tight, fabric material is not guaranteed or new clothes bought without washing well and many dust and dirt also cause irritation and penile pimples. Eating allergenic foods can also irritate the skin and, if unfortunately, the skin is as delicate as the "genital area".

  •  
    Estrogens, through elevated aromatase activity, in men is associated with increased inflammation and thus prostatitis and precancerous conditions of the prostate.

If offered a picture of an unknown woman in front of a man, and asked him if he liked it? - 0 views

  •  
    His answer would be probably after a little thinking: "Yes" or "No", he will know the answer clearly and completely. But if our offer image unknown man and we raised the same question on the mirror, it will be assumed her answer: "I'm still not sure, it comes to how I would feel after in-depth knowledge and deal with it, and maybe then you will know." Difference in libido between the sexes! Differences in approach in the expression of feelings is not a coincidence, it is a clear and distinct. Is it possible that women are more reluctant than men? Or maybe the point of view based on the components did not know the men? Studies suggest that women need more information to see her passion and expression of feelings toward the man standing front of them, including. http://www.weightloss24.tk/2015/02/is-sexual-arousal-vary-according-to.html

Estrogen Mediates Metabolic Syndrome-Induced Erect... [J Sex Med. 2014] - PubMed - NCBI - 0 views

  •  
    animal model finds that high fat diet induces ED more through increased Estradiol production than low Testosterone.  Of course the authors focused on the drugs to block E2 once produced, rather then reducing the T to E2 aromatase activity.  This metabolic syndrome model implies that increased aromatase activity will be present.

The Role of Androgen in the Adipose Tissue of Males - 0 views

  •  
    great review of the current knowledge of how adipose tissue influences androgen production and how androgens influence adipose tissue.  For example, leptin has an androgen inhibition centrally and peripherally.

Impact Of Unimaginable Harms Of Chickens Chicken Prevention - Men's Health Clinic - 1 views

  •  
    The harmful effects of chicken papilloma disease not only stop at physical health but also the spirit of patients is seriously affected. Patients may be depressed, mentally in crisis when they know that they can follow them all their lives. Chicken ridge is considered the undeniable obsession of men. Referring to this disease, many boys are bored, because once they get sick, the chicken's neck often hangs and leaves many harms. Dr. Vo Duy Tam said, "The chicken's crest is a sexually transmitted disease caused by HPV (Human Papilloma Virus) - The virus causes human papilloma. Currently there are more than 130 HPV types that have been discovered, among them, the ones that often cause genital warts are types 6, 11, 16, and 18.

An endocrine pathway in the prostate, ERβ, AR, 5α-androstane-3β,17β-diol, and CYP7B1, regulates prostate growth - 0 views

  • Although the prostate is an androgen-dependent tissue, estrogens influence both normal functions and pathological changes in this gland
  • This dual action may be due to the existence of two estrogen receptors, ERα and ERβ
  • ERα and ERβ have similar affinities for estradiol-17β
  • ...6 more annotations...
  • In this study we have shown that regulation of the levels of 3βAdiol by CYP7B1 is a key factor in regulation of prostatic growth
  • We provide evidence that proliferating cells in the prostate epithelium have elevated levels of AR and that AR protein but not mRNA levels are regulated by ERβ and its ligand 3βAdiol in the prostate epithelium.
  • because inhibition of 5α-reductase causes accumulation of testosterone and removal of ERβ action increases the level of AR in the prostate, the overall effect of Finasteride would be to favor proliferation of the prostate epithelium
  • studies show that ERβ tends to be lost in advanced prostate cancer.
  • DHEA is converted in the body to 5-androstene-3β,17β-diol, which is also a ligand for estrogen receptors (25, 39) and a substrate for CYP7B1
  • At the peak of proliferation, the proliferating epithelial cells in the ventral prostate expressed high levels of CYP7B1 but had no detectable ERβ, whereas in nonproliferating cells the level of ERβ was high and that of CYP7B1 was low.
  •  
    3-beta androstanediola, a product of 3alpha-HSD from DHT binds to ER beta and down regulates AR in prostate cancer.  This study proposes that the mechanism is via CYP7B1.  CYP7B1 inactivates 3-beta androstanediol.  Interesting, because 3-beta androstanediol is considered "inactive" when compared to 3-alpha androstanediol and its interaction with ER alpha.
