    Progesterone (or pregnenolone) - a cheap, safe and effective treatment of infertility

    It looks like Big Pharma is getting desperate and are now setting their sights on progesterone. The studies showing benefits of bioidentical progesterone have been steadily increasing over the last 5+ years and it probably won't be long before a pharma company asks the FDA to declare...

    Guy on forum claims he can only have sex when on heavy drugs & impulsive -- thoughts? Being honest, hardworking, even good looking guy doesn't cut it?

    I noticed this post and thought I'd share it here to have feedback. Why would a guy ONLY be able to have sex if he's taking three steroid compounds at super-physiological doses? We're not saying roids help his confidence, his sense of self, they literally -- according to him -- EXACERBATE more...

    Why I think men/males go bald (recede), but females/women rarely do

    Okay, so I've been thinking of this -- and although it's not based solely on any scientific analysis or even deep knowledge -- it is a theory of mine I don't think I've seen anyone else postulate. This is a fairly long post -- & I don't have the "linguistics" to define every idea I have super...

    Lost my Sex drive because of Progesterone Cream

    Hi, I’m a 28 year old male and I used Progesterone Cream (3-5mg) per day for 2 weeks on my face to reduce some fine wrinkles (crows feet). It worked but my Sex Drive is non-existing right now. What to do and should I worry? I always had high Libido. I stopped using it for 3 weeks.

    Drinking Pepsi/Coke freely is androgenic for males, enlarges testicles, ups testosterone

    I think the sales of Coke/Pepsi are about to go through the roof. The study sounds like it was sponsored by one/both of the soda makers, but it was not, and in fact is corroborated by prior studies on (human) male fertility and sugar consumption that I posted about in the past. The study below...

    Hypogonadism in older males due to low OXPHOS

    I suspect many readers will simply say "duh!", but believe or not the origin of age-related hypogonadism in males is still considered unknown. Most endocrinologists have discovered experimentally that treating their patients with SERM or AI drugs restores androgens to youthful levels, but the...

    Thoughts on THIS BOOK? "The Manipulated Man" - Female author bashes women/supports (redpilled?) men AKA battle of the sexes!

    I had never heard of this book ... Apparently it's a female author (surprising?) who elaborates on how women only are capable of making men in to their slaves AKA women rule over men. Also relevant to some previous threads here since this is about the "battle between the sexes" AKA the...

    Vitamin A is required for male fertility

    I am posting about this study not because I am thrilled at the possibility of society now having oral (non-steroid) contraceptive methods for males, but rather because this study highlights that vitamin A is actually required for male fertility. Even minor interference with so-called retinoic...

    Waking up early with painful morning wood

    I usually go to bed between 11pm and 12am and sleep 8 - 9 hours but lately I have been waking up at 5 or 6am with extreme morning wood. It's actually a little painful and causes me to wake up.

    Dietary PUFA In Childhood Causes Diabetes And Irreversible (male) Infertility

    A great study, which corroborates the discussion in another recent post of mine on PUFA's role in infertility and insulin-resistance / diabetes. However, the study below found that the infertility caused by dietary PUFA exposure were NOT reversible upon discontinuation of the high-fat (both PUFA...

    Male Sexual Function Does NOT Require Estrogen

    It is a "sacred" mantra in the medical and sports worlds - i.e. "estrogen is crucial for males, without it they won't have any sex life". This mantra is also part of the justification given for the currently ongoing COVID-19 clinical trials with males receiving estrogen in the hope it will...

    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

    Testosterone Does NOT Impair Empathy In Men

    I am sure most readers are quite familiar with the cliche that testosterone (T) is what drives stereotypical "boy behavior" - aggressiveness, carelessness, impulsive behavior, risk taking, cheating, and of course the militaristic attitude characterized by lack of (or reduced) empathy. As I...

    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...

    Androsterone May Be The Main Source Of DHT, Drives Fetal Masculinization

    The study below demonstrates that not only may androsterone be the primary pro-hormone used endogenously for DHT synthesis, it likely also drives the masculinization of sexual organs in the fetus. For a long time it was thought that the so-called "front pathway" using testosterone (T) produced...
