HOW WELL DO THE SPERM SURVIVE THE FREEZING PROCESS?
Usually 50-60 percent of the sperm retain motility when thawed. However, this will vary depending on the quality of the semen and the freezing capability of the individual specimen. Poor quality specimens do not freeze as well as normal semen specimens. An analysis report of the pre-freeze and post-thaw parameters will be sent to the referring physician. HOW TO ATTEMPT PREGNANCY WITH CRYOPRESERVED SPERM? The insemination of thawed sperm is performed by a physician by artificial insemination around the time of ovulation. This can be either intra-cervical insemination or inter-uterine insemination. A specimen used for inter-uterine insemination must be washed before it can be inseminated. Ovulation monitoring is required during the desired month of conception with insemination of the cryopreserved sperm at the appropriate time. Depending on the specimen parameters, one or more vials of cryopreserved sperm may be used for each insemination. As a guideline, at least 20 million motile sperm
