    Stress ups cortisol/estrogen/prolactin, drops DHT, causes male infertility and prostate issues

    If you try to discuss infertility with a fertility/reproductive specialist or an endocrinologist, and mention that chronic stress may be a factor in infertility, you will probably get laughed out of the room. This is not just speculation. This exact same thing happened to several friends and...

    Bile acids alter male fertility through G-protein-coupled bile acid receptor 1 signaling pathways in mice

    Bile acids alter male fertility through G-protein-coupled bile acid receptor 1 signaling pathways in mice Bile acids (BAs) are signaling molecules that are involved in many physiological functions, such as glucose and energy metabolism. These effects are mediated through activation of the...

    Could The Covid-'Vaccine' Make Females Infertile?

    Dr. Wolfgang Wodarg raised this question. Corona viruses use spike proteins to get entry to the cell. The mRNA covid-'vaccines' are designed to make your cells produce something like these spike proteins, and this shall encourage the body to produce antibodies against those spike proteins...

    Estrogen Lowers T, DHT, And Fertility; Inhibits 5α-Reductase (5-AR)

    I am posting this study below as a response to numerous angry emails I have been getting over the years. People sending me those emails just cannot accept the idea that estrogen can be detrimental for males (and females as well), and that estrogen levels are directly antagonistic to the male...

    Eating 1 Lb Of Sugar Daily Has Strikingly Positive Effects On (male) Fertility

    When I saw this news article pop up in my daily feed I immediately thought to myself "This study will never get covered by large mainstream news outlets". And of course, the websites of CNN, Fox, ABC, CNBC, USA Today, etc have no trace of an article covering the study or even just the basic...

    Male Fertility Depends On Intensity Of (sperm) Metabolism

    Yet another aspect of health that turns out to be directly controlled by quality/speed of metabolism. I made a few posts in the past demonstrating that progesterone and pregnenolone activate a calcium channel (CatSper) specific to progesterone, which greatly increases sperm motility...

    Niacinamide May Restore Female Fertility In Old Age

    The mainstream medical dogma is that after the onset of menopause, female reproductive potential is essentially zero. I posted a thread recently that challenged that dogma and demonstrated that infertility is essentially an energetic dysfunction process and can be reversed with exposure to red...

    Fertility Depends On Metabollism (ATP), Not Age

    As many of you know, there are 2 fundamental dogmas in reproductive medicine. One is that every woman is born with a fixed number of eggs and those cannot be replenished. The second one is that there is a biological fertility clock in every woman that inexorably ticks, and if the female does not...

    Remarkable Decline In Fertility - Half The World Below Replacement Levels

    I posted a few related threads on the topic of the declining reproductive health before. Sperm counts in males have declined by more than 60% since the 1970s. Sperm Count (a Surrogate For Male Health) In The West Has Declined By 60% Since The 1970s However, that finding does not seem to be...

    Dads Pass On More Than Genetics In Their Sperm

    Another good study showing that our lifestyle choices directly affect our future children, despite what the morons in white coats keeps repeating. It has been known for years that dads in poorer health tend to beget more sickly children but the explanation had always been genetic - i.e. the dad...

    Lanosterol - Liquid Lanosterol For Lab/R&D

    I guess most people on the forum who have heard of lanosterol know it in the context of treating cataracts. Lanosterol - Wikipedia There is a company out there who used to sell lanosterol as eye drops and it is insanely expensive - $100 for a meager 10mg lanosterol. Anyways, lanosterol is...

    Cortisol/Estrogen Impair Fertility; Progesterone/Pregnenolone Improve It

    I posted a study s few months ago about the role of progesterone in ensuring proper sperm motility, and as such being crucial for male fertility. Male Fertility Requires Progesterone And Antagonism Of A PUFA Metabolite This new study from the same authors analyzed the effects of a few other...

    Genomic Mechanism For Beneficial Effects Of Progesterone On Pregnancy / Cancer

    Apparently, the gene Gata2 is crucial for the protective effects of progesterone against estrogen carcinogenicity, as well as for ability to enable pregnancy formation. GATA2 - Wikipedia This study found that progesterone acts as a Gata2 agonist and absence of the gene makes mice infertile as...

    Fertility Problems In Women Could Be Due To High Cortisol

    Cortisol is highly antagonistic to progesterone - i.e. it both directly inhibits synthesis of progesterone and activates aromatase, so elevated cortisol results both in deficiency of progesterone and excess of estrogen. This human study found that women who had issues getting pregnant had...
