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]
