Protect Your Deposit With Sexually Transmitted Infection (STI) Testing

We recommend STI testing for everyone who intends on analyzing a semen sample followed by cryopreservation. While your journey today might not involve assisted reproductive technologies such as IVF, an STI test associated with your sample around the time of analysis and storage would enable retrieval and use in the future (we suggest within 10 days). A negative STI test associated with your specimen rules out STI related complications and reduces possible risk to mother and baby. Fertility clinics have varying requirements for accepting and using semen samples. Depending on your specific circumstances and the clinic you choose to use, completing STI testing within 10 days of storing your sample generates a report close to the time of sample cryopreservation which may be used as proof of a negative test for use of your sample at a later date. For more information on what kind of STI testing you might need, see our FAQ link below.

Some sperm is lost and damaged during the transport, storage, freezing, and thawing process. The semen analysis reflects values at the time of the analysis, after transport and before freezing. These values will decrease throughout the freezing and thawing process. A semen analysis alone cannot be used to predict fertility.
