what is the normal size of human testis
Testicle A length of a testicle can be measured with an orchidometer. Its volume is 15 to 25 ml.Template:Needs reference There is some evidence to suggest that average human testicle size and weight has been progressively diminishing in recent years among younger cohorts in Western industrialized nations. This may be associated with a decline in sperm counts. The recent changes suggest involvement of environmental or lifestyle factor(s) such as increasing exposure to endocrine disruptors.[1]
Prostate The classical description of a healthy human male prostate portrays it as slightly larger than a walnut. The mean weight of the normal prostate in adult males is about 11 grams, usually ranging between 7 and 16 grams.[6] A study stated that prostate volume among patients with negative biopsy is related significantly with weight and height (body mass index), so it is necessary to control for weight.[7] The prostate surrounds the urethra just below the urinary bladder and can be felt during a rectal exam.
