Precautions and Warnings

Sperm Freezing contains small amounts of Human Serum Albumin (HSA). The Human Serum Albumin used in the preparation of this product has been heated at 60°C for ten hours.

Caution: 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 be totally excluded. This also applies to unknown or emerging viruses and other pathogens. There are no reports of virus transmissions with albumin manufactured to European Pharmacopoeia specifications by established processes. It is strongly recommended that every time that Sperm Freezing is administered to a patient, the name and batch number of the product are recorded in order to maintain a link between the patient and the batch of the product.

Always wear protective clothing when handling specimens.

Always work under strict hygienic conditions (e.g. LAF-bench ISO Class 5) to avoid possible contamination.

Only for the intended use. Do not resterilize.
