Evaluation Study Between Density Gradient and Swimming Down for Semen Processing

Summary

This study evaluates the quality of sperm produced after semen processing using Density Gradient (DG) and swimming down (SD).

Conditions

• Infertility

Interventions

PROCEDURE

Diff-Quik staining for morphology evaluation

Papanicolaou stain (haematoxylin, orange G6, and EA50) gives a clear difference between basophilic and acidophilic cell constituents and thereby enables a detailed examination of chromatin pattern, which is useful in the evaluation of sperm morphology and assessment of presence of immature spermatozoa. Cytoplasmic staining can vary between red and green dependent on ionic strength, pH, and composition of the cell department and the stain (OG6 and EA50). Morphological assessment for processed portions of semen. As separation process has to minimize the morphological abnormal sperm.

PROCEDURE

Motility Evaluation for grade A and B

The better separation method will insure more progressive sperms after processing. Grading using A and B scale scored by (WHO 2010) references.

PROCEDURE

Concentration (mil/ml)

count of isolated sperms Using Makler chamber for count of sperm for each portion post processing.

PROCEDURE

24 H half life

percentage of active motile to non motile sperms. Microscopic examination for each sample after 24 hours incubation, to evaluate the progressively motile sperm and those non progressive or non motile.

PROCEDURE

48 H half life

percentage of active motile to non motile sperms. Microscopic examination for each sample after 48 hours incubation, to evaluate the progressively motile sperm and those non progressive or non motile.

PROCEDURE

HBA Testing

The Hyaluronic Binding Assay (HBA®) is an important diagnostic tool for suspected male infertility in the analysis of semen. In a matter of minutes the HBA® slide provides an answer to the proportion of mature binding spermatozoa in the sample (The HBA® score %). By using HBA slide we can count the physiologically active sperms at each sample and calculate percentage of active sperms with reference to post processing count from 3rd investigating arm.

BIOLOGICAL

Bacterial contamination

Routine bacterial culture using Blood Agar culture plates for 10 micron finally washed samples, to confirm presence of any bacteria contamination caused by carry over during processing.
