An evaluation of the hypo-osmotic sperm swelling test as a predictor of fertilizing capacity in vitro

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

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...

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...

Comparison between sperm treated with pentoxifylline and 2-deoxyadenosine using hypo-osmotic swelling test.

OBJECTIVE To compare the percentage of sperm tail membrane swelling under hypo-osmotic conditions between sperm treated with pentoxifylline and 2-deoxyadenosine. DESIGN Experimental in vitro study. MATERIAL AND METHOD Thirty normal semen samples from male partners of infertile couples were collected. After sperm preparation by two-layer Percoll gradient method, each sperm sample was divided...
