GM501 PVP is a ready-to-use medium to reduce the motility of sperm, making it easier to catch them with an ICSI pipette.

Product facts and notices

Composition

GM501 PVP is 10 % dialysed PhEur grade polyvinylpyrrolidone solved in an aqueous solution containing physiologic salts, HEPES, lactate, pyruvate, glucose and human albumin solution.

Product specifications and quality control

• All raw materials are of highest available purity (European Pharmacopoeia and/or USP standard) if applicable.
• GM501 PVP has been evaluated by an independent test laboratory using the ISO 10993-5/USP30-NF25 Agar Diffusion test for cytotoxicity. The product was considered non-cytotoxic.
• A certificate of analysis is available for each batch upon request from our website with respective Lot number.
• The MSDS for the media are available upon request and can also be downloaded from our website.
• GM501 PVP is manufactured according to the following specifications:

Instructions for use:

Evaporation of the PVP solution on the slide or dish and the presence of human albumin may occasionally cause a small amount of precipitation in the medium.

Standard procedure:

1. Warm the PVP solution to 37°C.
2. Place a small drop of PVP solution (5 μl – 10 μl) in a dish and cover with GM501 MineralOil.
3. Add a small volume (1 μl – 2 μl) of washed sperm into the centre of the PVP droplet.
4. Wait for a few minutes to allow sperm to migrate to the periphery of the droplet.
5. Select and recover the spermatozoa for injection.

Alternative procedure (with extra washing step):

1. Warm the PVP solution and HEPES-buffered sperm processing medium to 37°C.
2. Place a small drop of PVP solution (5 μl – 10 μl) and 1 or more small drops HEPES-buffered sperm processing medium in a dish and cover with GM501 MineralOil.
3. Add a small volume (1 μl – 2 μl) of washed sperm into the centre of the PVP droplet.
4. Wait for a few minutes to allow sperm to migrate to the periphery of the droplet.
5. Select the spermatozoa for injection and nick (break) the tail of the spermatozoon with the tip of the pipette.
6. Transfer the spermatozoon into one of the HEPES-buffered sperm processing medium droplets and wash by transferring the sperm cell in and out of the sperm processing medium several times.
7. Aspirate the sperm cell into the pipette and use for ICSI procedure.

Precautions and warnings:

• Standard measures to prevent infections resulting from the use of medicinal products prepared from human blood or plasma include selection of donors, screening of individual donations and plasma pools for specific markers of infection and the inclusion of effective manufacturing steps for the inactivation/removal of viruses. Despite this, when medicinal products prepared from human blood or plasma are administered, the possibility of transmitting infective agents cannot totally be excluded. This also applies to unknown or emerging viruses and other pathogens. There are no reports of proven virus transmissions with albumin, manufactured to European Pharmacopoeia specifications by established processes. Therefore, handle all specimens as if capable of transmitting HIV or hepatitis. Always wear protective clothing when handling specimens.
• GM501 PVP medium does not contain any antibiotics. Always work under strict hygienic conditions (e.g. LAF-bench, ISO Class 5) to avoid possible contamination.
• The long term safety of ICSI, including the use of PVP, on children born following this procedure is still under investigation.
• Only for the intended use.

Pre-use checks:

• Do not use the product if bottle, seal of the container or package is opened or defect when the product is delivered.
• Do not use the product if it becomes discoloured, cloudy or shows any evidence of microbial contamination.
