Sperm freezing for fertility preservation and potential future fertility treatment. This may suit men undergoing gonadotoxic chemotherapy or testicular surgery, taking medication associated with sperm abnormalities, planning gender transition, experiencing progressive mobility issues, ejaculatory or erectile problems, extremely low sperm count, living away from their partner, or frequently travelling to areas with Zika virus exposure. The clinic provides instructions about abstinence and what to avoid. The doctor and embryology team determine the number and timing of samples required. Patients normally attend once a week to produce a sample, which is then frozen for future treatment.
