REVISION OF HYPO-OSMOTIC SWELLING (HOS) TEST WITH A PROPOSITION OF CLASSIFIED GRADING SYSTEM: iTS COMPARISONS WITH FOUR DIFFERENT TYPES OF HUMAN SPERM SEPARATION TECHNIQUE

Correlation between Different Patterns of Hypo-Osmotic Swelling and Sperm Functional Tests

Establishment of an optimal hypo-osmotic swelling test by examining single spermatozoa in four different hypo-osmotic solutions.

In order to find an optimal hypo-osmotic swelling test (HOST) and to identify viable sperm cells from patients with asthenozoospermia for intracytoplasmic sperm injection (ICSI), we tested single motile and non-motile spermatozoa in four hypo-osmotic solutions by micromanipulation. The four solutions were: A, H2O; B, 50 mOsm NaCl; C, 150 mOsm NaCl and D, 150 mOsm sodium citrate and fructose. Eo...
