Sperm counts alone cannot predict future fertility. Different amounts of sperm are needed to attempt conception through different routes, such as sexual intercourse, intrauterine insemination (IUI), and in vitro fertilization (IVF). Some sperm is lost and damaged during the storage, freezing, and thawing process. The semen analysis reflects values at the time of the analysis, before freezing. These values will decrease throughout the freezing and thawing process. Semen parameters may vary in any individual depending on many factors. The results in your report are for the sample sent only and may differ from other samples in the same individual. Many clinics offering fertility services have infectious disease screening requirements prior to use of stored samples. We recommend that all clients who are planning on storing their sample with Ro complete an STI screening prior to beginning the process.
