Elevated salivary am cortisol predicts increased risk of depression in boys.  

Probably one of the more disturbing aspects of glyphosate exposure. In utero exposure, lowers Testosterone levels and effects the masculinization process of the young boy.  Very disturbing.  Our boys are being altered before they are even born.

boys receiving HBV had 2.94 greater incidence of Autism Spectrum Disorder vs later or unvaccinated boys

New study shows that obese boys/young men pre and post puberty have up to 50% lower testosterone levels than comparative normal BMI counterparts.  Also of note, estradiol levels were not associated with the low testosterone levels.

Study of 12-14 y/o boys found increased Testosterone after resistance training and plyometric exercise.  Cortisol did increase after plyometric, but not resistance exercise.

phthalate exposure associated with reduced masculinity of boys

Letrazole improves growth potential in boys with HGH deficiency through aromatase inhibition and delayed closure of the growth plates

Causes of itching For men, the cause of the itch can be divided into three groups: * The "little boy" hygiene is not right: Men - especially young people - often do not focus or "lazy" to clean the boy. This bad habit has gradually created an environment for the growth of genital fungi, causing an itching sensation. Besides, the selection of inappropriate cleaning solutions is also the reason that may be encountered in men. Some men reported using feminine cleaning solutions or shower gels to "bath" their "boy". This makes the itching condition more and more because the nature of the feminine hygiene solution is not suitable for his small skin, so it can easily lead to skin irritation, even leading to a disorder of the skin and creating favorable conditions for mushroom growth.

Finnish study of 3,271 men found that there was a decline in serum free testosterone levels in recently born boys compared to previous generations.  Additionally, they found inappropriate HPA response to this decline in testicular testosterone.

In utero organophosphate exposure linked to ADHD, especially in boys.

low testosterone in boys associated with anxiety/depression and attention problems.  Disruptive behavior found in girls with low testosterone.  All determined by salivary testing.

case study of a young boy with MADD treated with ketones. Significant improvement/resolution after 5 months of therapy with ketone therapy.  There was even improvement in brain MRI.

weight loss decreases leptin in boys and the result is an increase in Testosterone

Study supports the mechanism behind endocrine disruption of xenoestrogens in the pubertal development of young boys.

New study suggests that intra-uterine exposure effects prefrontal cortex development that leads to autism.  This study was conducted of postmortem samples of children with autism ranging from 2 to 15. Intra-pregnancy exposure of what?  That is the question.  Environmental toxins: whether it is all the xenoestrogens (autism at rate of 5:1 in boys), PCBs, heavy metals, and yes (lead author) preservatives, metals (Al and thermeresol) in vaccines--particularly the flu vaccine which ACOG is almost mandating during pregnancy.

aromatase inhibition therapy shown to reduce and/or eliminate man boobs in young boys with sertoli cell tumors.

low dose pesticide (organophosphates) exposure associated with delayed sexual development in boys and girls.  In addition, there was an inverse correlation with free T4 and a positive correlation with TSH.  

Phthalate exposure is a cause of low Testosterone in men, women, and children.   In boys 6-12, exposure was associated with a 24-34% reduction in Testosterone.

interesting read on hormones and tourette's.. Proposed that 5 alpha reductase activity is involved in worsening of tics.  This makes sense as Testosterone in men with low T is known to increase dopamine and dopaminergic dysfunction is known to play a role in tourette's;  the clinical presentation of girls vs boys is very different.  The authors of this article propose that 5 alpha reductase activity controls a back door method where by progesterone is converted to androgens.
