Fertility preservation is a medical approach that enables patients to store reproductive potential for later use. This approach consists of freezing techniques for eggs, sperms, or embryos, which are mostly recommended to those patients who are going to undergo treatments affecting fertility, such as chemotherapy. The process initiates with the stimulation of ovaries for the retrieval of eggs or collecting sperms in men, following which they are frozen and stored. For women, other options include ovarian tissue preservation. It is an opportunity, critical for the preservation of fertility, for people who have health issues or delayed family planning to be able to continue hoping and having options for parenthood in the future.
