  This is an image of the corpus luteum, found in the female reproductive system after ovulation. This occurs when the follicle ruptures and collapses, consequently filling the organ with blood causing it to clot, called corpus haemorrhagicum. It is through this that corpus luteum is formed. The granulosa cells expand and become vesicular, giving rise to the granulosa lutein cells. As you can see, these become folded.
  
  Theca interna cells, which expand and become glandular, occupy the spaces between the folds and are now known as theca lutein cells.
