Visually analyzing tests size is a poor method of judging your actual testicular function, since testicular size is not directly related to the ability to secrete testosterone. This is because the Leydig cells, which are the primary sites of testosterone secretion, only make up about 10% of the total testicular volume. Therefore, when the tests may only appear 5-10% smaller, the testes ability to secrete testosterone upon LH or Hcg stimulation can actually be significantly reduced to 98% of their normal production. The point here is to not judge testosterone secretion capacity by testicular size.........Ghostprofit
