Preliminary evaluation of methylcellulose as an alternative rate control medium for the acquiring of high quality spermatozoa in swim-up

involved. Independent of the processing method, cryopreservation appeared to more effectively suppress mild growth patterns versus heavy bacterial presence (15.4 vs. 64.3%, P 1⁄4 0.003). CONCLUSION: It remains paramount to inform patients how to properly collect specimens for IVF. While it is advisable to assess for presence of bacteria in semen, a proper sperm selection with cryopreservation may obviate this need. This may serve to reduce cost and discomfort for the patient while granting safety for the ART procedure. Therefore, a precious cryopreserved semen specimen with a positive culture may be reassessed for bacterial growth and not discarded. Supported by: Institutional.
