Tubular fertility index

{
  "id": "MLC-T-CHM-012343",
  "term": "Tubular fertility index",
  "field": "Chemistry",
  "definition": "The share of tubules in a histological section of the testis in which spermatogonia can be recognized, expressed as a percentage. Spermatogonia are the germ cells at the start of spermatogenesis, so the index is used in toxicology as a measure of germ cell survival. A value of 100 percent means every tubule examined holds spermatogonia, and lower values indicate tubules depleted of germ cells.",
