Serotonin puts the brakes on libido, by lowering dopamine

Nothing really surprising, as far as Peatarians are concerned, in the findings of this study. I am only posting it here as it is one of the few that officially acknowledge that serotonergic drugs cause sexual dysfunction – i.e. something mainstream medicine has vehemently denied for decades. As such, it corroborates the approach of using … Read more

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 relatives who struggled to conceive, and it is … Read more

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 and MUFA) diet, while previous studies found that the infertility … Read more

Dietary PUFA causes (reversible) male infertility and androgen deficiency

An amazing study, which should serves as a causing to the nuts-and-seeds crowd precisely because it used exactly such a diet to produce these highly negative effects on male fertility. Come to think of it, it is common knowledge in many cultures around the world that seeds and seed extracts are often used as male … Read more

TSH in the mid-normal range can cause female infertility

A great study that exposes the utter absurdity of the ranges currently defined as “normal” for a number of biomarkers, but especially for TSH, prolactin, testosterone, estrogen, liver function, albumin, etc. Out of those, perhaps the most absurd example is the range for TSH. The “normal” range for TSH has been redefined a number of … Read more

PUFA may be a major factor in sterility

Just a few days ago I made a post about PUFA driving obesity, inflammation, and liver damage in diabetes II patients. The omega-6 fatty acid DLGA (a metabolite of linoleic acid) was the main pathological factor examined in that study. Now, a new study study demonstrates that DLGA may also cause sterility. Official estimates indicate … Read more

Low-dose (but not high) niacinamide reverses reproductive decline in old females

A great new study, which once again confirms the importance of metabolism in “aging” disorders such as infertility (both female and male) and menopause. More specifically, it was the increase in NAD/NADH ratio that was the main mechanism of action behind the beneficial effects of nicotinamide mononucleotide (NMN) the study below discovered. Now, the study … Read more

Almost 40% of military women (and even more military males) are infertile

I think this study should dispel some of the myths about what being “fit” really means, and that being truly healthy or “fit” often are quite divergent paths. Infertility is actually one of the most reliable indicators of poor systemic health and predictor of future chronic disease (in both sexes). So, by that measure, almost … Read more
