Testosterone and Prostate Cancer - Bye Androgen Hypothesis, Welcome Saturation Model

 

A long-held belief is that testosterone stimulates development of prostate cancer and/or accelerates its growth. This fear is the most common reason for doctors' reluctance to prescribe testosterone replacement therapy, even in hypogonadal men [1, 2] , which unnecessarily deprives many hypogonadal men of clinical benefits.
 
This summary gives an overview of an in-depth review of current literature regarding the relationship of testosterone levels and prostate cancer, and the effect of testosterone replacement therapy on prostate cancer progression and recurrence.[3] Key studies which have refuted the old belief that testosterone has harmful effects on the prostate are presented, along the new testosterone-prostate paradigm known as the saturation model.
 
Surprisingly, new research provocatively suggests that it is not high testosterone levels that are problematic for prostate cancer, but to the contrary that it is low serum T that is associated with worrisome cancer features and outcomes...and new experimental research has uncovered mechanisms that explain how low testosterone levels may be detrimental for prostate health, and support the new view that testosterone therapy actually may have beneficial effects with regard to prostate cancer...
 

Walnuts Improve Semen Quality in Men Consuming a Western-Style Unhealthy Diet

It is well-documented that maternal food habits and essential nutrient intakes have an important impact on reproductive outcomes.[1, 2] However, there is less information available on the importance of nutrition for paternal reproductive fitness. Evidence is particularly limited for men who habitually
Consume a Western-style unhealthy diet which is lacking in many essential nutrients and omega-3 fatty acids, which are needed for healthy sperm and fertility.[3-13] Omega-3 fatty acids are especially important for proper sperm morphology and function.[5, 6, 8, 9]
 
Raw unprocessed walnuts are a rich source of essential nutrients and provide an array of health promoting phytochemicals, including carotenoids, phenolic acids, phytosterols and polyphenolic compounds such as flavonoids, proanthocyanidins (PAC) and stilbenes.[14-18] Therefore, a study specifically investigated if in young men (age 21-35 yr old) habitually eating unhealthy, adding 75 g of whole-shelled walnuts per day would have an impact on semen quality...[19]
