Inflammatory and non-inflammatory conditions can result in loss of seminiferous tubules within the testes. Sperm-producing cells are taken from the seminiferous tubules in the testes. These are cells of the seminiferous tubules of the testis that act to provide the optimal environment for the development of the spermatozoa. At puberty, the seminiferous tubules fail to enlarge normally and instead undergo fibrosis.
