How to grow the testicles?

Question

In healthy  adult humans, average testicular volume is 18 cm³ per testis, with normal size ranging from 12 cm³ to 30 cm³. The average testicle size after puberty measures up to around 2 inches long, 0.8 inches in breadth, and 1.2 inches in height (5 x 2 x 3 cm).
Your body uses zinc to produce sperm inside your testicles. Supplement with 30mg per day and you will see an increase in the size of your testis, due to increased sperm volume. You'll also notice an increase in the size of your ejaculations. Excess estrogen causes atrophy, or shrinking of the testicles.
