An osmotic resistance test (ORT) was developed for bull semen. Raw semen was incubated
for 40–60 min at 35° C in a fructose/sodium citrate solution with an osmolarity of 150 mOsm …

Hypoosmotic tests are widely used as valuable tests for determining sperm quality in
species as varied as the human and the porcine. However, there is little information about …

The functional integrity of the membrane of sperm from semen samples collected from 10
fertile men (Group A) and from 50 infertile men (Group B) was assessed by studying the …

Expression of progesterone receptor (PR) localization on spermatozoa was determined in
men with normal and abnormal spermiograms. Studies were also carried out to evaluate the …

Sperm‐cell volume, measured electronically by cell counter, is a parameter providing
information about the state and integrity of the plasma membrane by determining cell …

The plasma membrane is a key organelle with respect to sperm fertilizing ability. A sensitive
way of testing plasma membrane functionality is to examine the sperm ability to moderate its …

The hypo‐osmotic swelling test was claimed to assess an independent functional
characteristic of human spermatozoa bearing relevance to their fertilizing capacity. To test …

Semen analysis procedures vary between institutions. There have been several attempts to
standardize some of the procedures so as to facilitate inter-laboratory comparison of data …

OBJECTIVE: To develop a rapid, sensitive, and reproducible hypoosmotic swelling test kit
for the assessment of plasma membrane integrity of human sperm in vitro. DESIGN …

This study evaluates the clinical usefulness of one additional parameter for assessment of
human sperm cell function in vitro—the hypoosmotic swelling test. The hypoosmotic swelling …
