    Diagnosed with early maturation arrest: I can't make sperm. Any ideas?

    I had my testicles biopsied in 36 different regions (Fine Needle Aspiration), and the pathology results showed early maturation arrest in all sites. The process stops at the primary spermatocyte stage for me. I had a varicocele repair 8 months ago, but it hasn't helped yet. I have normal...

    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...

    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...

    Sperm Count (Biomarker Of Male Health) In The West Has Declined By 60% Since The 1970s

    This topic has been discussed on the forum a few times before but the humbers quotes by recent studies usually hovered around 20% - 30%, which did not cause much alarm among endocrinologists. Now, this larger study shows that the decline in male fertility is much worse than previously thought...

    Male Fertility Requires Progesterone And Antagonism Of A PUFA Metabolite

    Ray has written many times on progesterone's role in both female and male health. This study discovered that sperm actually has a progesterone "receptor" on its tail, and it is the activation of this "receptor" by progesterone that allows sperm to make the final push into the egg and perform the...
