Hypo-Osmotic Sperm Swelling Test Does not Assess Fertilizing Capacity of Human Spermatozoa

Evaluating the Functional Status of Spermatozoa in Smokers Using Hypo-osmotic Swelling Test

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...

Time course of hypo-osmotic swellings of human spermatozoa: evidence of ordered transition between swelling subtypes.

The hypo-osmotic swelling test (HOST or HOS test) usually takes into consideration the total HOS response value with no emphasis either on the value of the response subtypes or the response evaluation time. This study investigated the time course of HOS responses and analysed their physiological relevance. Raw semen spermatozoa and Percoll washed spermatozoa were used in the experiment. The mor...

The role of hypo-osmotic swelling test in recurrent abortions.

The role of male factors in abortions has not been studied extensively. We undertook this study to determine if there was any relationship between hypo-osmotic swelling test score and recurrent abortions. This was a cross-sectional case control study conducted at the semen analysis laboratory at a tertiary level referral centre. The male partners of 25 patients who had three or more first trime...
