Sperm Post-Donation Storage Procedures
Here's a simpler overview of the steps involved in storing sperm after donation:
First, we collect and analyze the sperm for quality.
Each sample is labeled and documented for identification purposes. Before the samples are thawed for use, they are kept in quarantine, and the donors are retested for infectious diseases to ensure their safety.
Once the thawing process is complete, the samples are prepared. Thawed sperm is then prepared for use in artificial insemination or in vitro fertilization (IVF) procedures.
These storage methods help maintain the long-term viability of donor sperm, allowing it to be used for various fertility treatments when needed while adhering to strict quality and safety standards.
What are the methods used for storage after sperm donation?
Methods used for sperm storage after donation:
● The primary method iscryopreservation, which involves using liquid nitrogen to freeze sperm in individual vials with special protective substances.
● Rapid freezing, called vitrification, is sometimes used for delicate or low-quality sperm.
● Quality control is also important. Semen analysis evaluates the quality of sperm prior to and following freezing, with appropriate identification and record-keeping.
● Donated sperm is isolated, and contributors may undergo additional assessments for infectious diseases.
● Cryopreserved sperm is defrosted and processed for implementation in fertility procedures such as insemination or IVF.
These methods used to store sperm make sure that donor sperm is stored safely in the long term for future reproductive use.
How Long can Sperm Be Stored After Donation?
The sperm storage time or duration of donor sperm varies but typically ranges from several years to several decades. Factors influencing storage duration include local regulations, clinic policies, sperm donor consent, periodic quality assessments, and the recipients' needs. Specific details should be obtained from the sperm bank or fertility clinic where the sperm is stored.
How Long can Sperm Be Stored Without Freezing?
Sperm can be stored outside the body for a
short period without freezing, typically up to a few hours. The exact duration
depends on various factors such as temperature, storage conditions, and the
medium used to preserve the sperm. However, for long-term preservation and to
maintain sperm viability, freezing is the preferred method, allowing sperm to
be stored for several years or even decades in a frozen state.
