Individual fertility is precious and fragile. It can be lost or impaired for a variety of reasons, making it important to maximise and protect it for future family building purposes. Recognition and protection of individual genetic legacy is also becoming increasingly important from a medical standpoint, personal identity perspective, for personal privacy and security reasons and for the benefit of future generations as scientific, medical and genomic technology continues to rapidly advance. As such, it is important to take steps to protect individual fertility and genetic legacy not just for yourself but for the benefit of your partner/spouse and family too.
