A Very Important Step Before Artificial Insemination

Semen analysis is a very important step before any artificial insemination is carried out. Semen is a fluid containing sperm cells, which is released during ejaculation. A normal sperm count is above 20 million sperm per milliliter of semen. The volume of semen is normally more than 2 milliliters.

Beside the pure volume of sperm cells a semen analysis (seminogram or spermiogram) includes the microscopic evaluation of

  • sperm concentration: sperm number is counted (Mio cells/ml).
  • sperm motility/vitality : measures, how many sperm are moving progressively, non-progressively, or are immobile.
  • sperm morphology: evaluation of normal versus abnormal shape.

To create the seminogram you observe living sperm cells in phase contrast and stained sperm cell smears in transmitted light brightfield or fluorescence.
