Are there any environmental catalysts that can effect the development of the size of a penis, or does one's DNA determine it's absolute size irrespective of all other factors?
Environmental hormones (or depending on what school you went to chemicals mimicking hormones etc etc) in some places might play an issue.
A possible factor is infant circumcision. There are occasional discussions to that effect on the foreskin restoration sites. The theory being a tight cut restrains growth of erectile tissue [corpora cavernosa, corpus spongiosum] during puberty.Are there any environmental catalysts that can effect the development of the size of a penis, ...
The proportion of boys with a scrotum categorized as small and/or "not distinct from surrounding tissue" was also elevated for boys with short AGI (p < 0.001). AGD was significantly associated with penile volume (R = 0.27, p = 0.001), and penile volume divided by weight was correlated with AGI (R = 0.43, p = 0.001). Testicular volume, which was measured by orchidometer, is not shown here because participating physicians considered the measurement to be unreliable--a decision made before analyses of phthalate exposure.
Rapidly falling sperm counts in the United States. Rising rates of genital defects in male infants. Unprecedented numbers of cases of testicular cancer among young American males.
Scientists are increasingly worried that these problems are being caused by environmental estrogens -- man-made chemicals capable of interfering with the hormones that regulate the male reproductive system.
Exposure to these chemicals -- also known as endocrine disruptors -- may have such potentially serious consequences that the federal government has begun studying their effects even before scientific confirmation that they may cause health problems in men.
A new theory J was told by a close friend that the growth hormones that is given to beef cattle is causing new generation guys to grow much larger cocks, seems logical, whats your thoughts on this?
