Park Avenue Fertility and Reproductive Medicine offers both embryo and sperm cryopreservation (freezing) by our laboratory. Embryo freezing is offered to IVF patients that have embryos remaining in culture following a transfer or for couples wanting to wait before transfer. The embryos that were not transferred originally may be frozen in the laboratory using a technique called cryopreservation. The embryos will be stored in the frozen state in liquid nitrogen until they are thawed for transfer into the uterus. The transfer of these frozen, then thawed, embryos can result in a successful pregnancy.
Sperm cryopreservation is offered for a variety of reasons:
- For patients who travel and may not be in town at the time of egg retrieval or at the time of IUI.
- For patients who wish to have a “back-up” specimen at the time of egg retrieval or IUI.
- For patients with low sperm counts who may wish to “pool” specimens.
- For patients who will be undergoing chemotherapy.
- For patients who have sperm retrieved from the testis by surgical techniques.
