Sperm Freezing (Sperm Cryopreservation)
In the event that the male has to have radiotherapy and/or chemotherapy that can lead to infertility. If husband cannot be present on the day of his partner’s eggs collection due to various reasons such as a business trip or psychological reasons, sperm can be frozen in advance and stored. Unlike freezing embryos and oocytes, survival rates of sperm after freezing and thawing are high. Pregnancy rates following sperm freezing and thawing are close to those of fresh sperm.
