Sperm Freezing

If the male has to have radiotherapy and/or chemotherapy, this can lead to infertility. In some cases, if the husband cannot be present on the day, his partner’s eggs are collected for various reasons, such as a business trip or psychological reasons. In such cases, 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.
