Semen: gel fraction

  1. The gel fraction (mainly from the vesicular glands being removed from an ejaculate by syringe aspiration.
  2. Semen is much easier to handle and examine once this gel has been removed. Due to its cohesive nature, the gel is easily removed in this manner.
  3. An alternative method is to filter off the gel using a milk filter.
  4. Many sperm are lost by both methods but these losses are not significant: usually 200 to 1200 million sperm remain in the filtrate.
  5. Sperm numbers are lower at the onset of the season and rise towards mid-summer.
