A second specimen is placed on a slide, a drop of saline or Ringer's is added, and the specimen is squashed under a coverslip to allow sperm to leave the tubules.

In additiona, we have often found that sepcimens obtained in this way often contain only three to six tubules with poorly preserved architecture.
