    http://www.ncbi.nlm.nih.gov/pubmed/2515138 "We have studied testicular function in the biotin-deficient rat biochemically and morphologically. Serum testosterone and luteinizing hormone (LH) levels were decreased significantly in the deficient rats. Administration of biotin or gonadotropins to...

    Masturbation And Testosterone

    I am a huge fan of NoFap, which is a community of individuals who believe that masturbating to the point of orgasm with porn tends to limit the psychological capabilities in men, as well as having some profound physiological effects that most would warrant as unwanted. As a young man who...

    Progesterone, Testosterone, Allopregnanolone Are Serotonin Antagonists

    This study shows that some of the gonadal steroids act in a manner similar to the drug ondansetron - i.e. antagonize the 5-HT3 "receptor". While pregnenolone sulfate was not antagonistic to 5-HT3, taking pregnenolone metabolizes mostly into progesterone and allopregnanolone. So, it seems like a...

    Oral Progesterone Increases Testosterone And DHT

    This rodent study shows that a hefty oral dose of progesterone stimulated synthesis of and elevated the levels of both testosterone and DHT. It seems that if progesterone has any negative effects on male steroids it requires dosages higher than the ones used in the study. Speaking of dosages...

    Vitamin A Stimulates Testosterone Production

    I know some people here are trying to raise testosterone and have even asked Peat about it. Peat responded long the lines of "increase vitamin A and thyroid". It looks like he is right (again) about the vitamin A part. This study shows that both retinol and retinoic acid stimulated testosterone...

    Cancer "paradox": Testosterone Treats Prostate Cancer

    Not really a surprise to anybody following Peat, but maybe we can finally start seeing some Peat-friendly treatments for cancer such as drugs for increasing rather than decreasing testosterone in elderly men. http://news.sciencemag.org/health/2015/ ... ate-tumors "...Testosterone may be the...

    High Estrogen (not Low T) Causes Erectile Dysfunction (ED)

    The official version is that the issue is "blood flow" and that can be "improved" by increasing the production of nitric oxide (NO). It looks like the real culprit is actually high levels of estrogen. The condition (ED) is probably mediated through estrogen's effect on preventing smooth muscle...

    Calcium (and/or Magnesium) Raises Testosterone Levels In Men

    Ray has written that calcium lowers prolactin, which should result in higher dopamine, lower serotonin, and thus higher testosterone. In addition, calcium is considered one of the Electron Withdrawing Cardinal Adsorbent (EWC) in Ling's AI theory of the cell and Ray has said that it is one of the...

    Chronic Caffeine Ingestion Increases T And DHT Levels

    There have been several threads on this forum about raising testosterone (T) levels in males, and especially dihydrotestosterone (DHT) levels. DHT is considered the "king" of male hormones since it does not aromatize into estrogen (E), has very strong anabolic (i.e. building muscle and reducing...
