The impact of DSD on future fertility is dependent on several factors. The key determinant of fertility potential is the status of gonadal development and function, and whether the individual has ovarian tissue with viable oocytes, or testicular tissue capable of producing functional sperm. Fertility risk will be primarily determined by the underlying diagnosis, modified by several additional factors. Whilst fertility preservation options are well established for many patient groups such as those receiving gonadotoxic treatment for cancer, there are a number of important additional considerations for those with DSD that must be evaluated on an individual patient basis. This includes potential for ongoing germ cell loss, risk of gonadal malignancy, genetic risk to offspring and factors related to feasibility of future use of gonadal tissues or gametes . Developing appropriate fertility preservation options in individuals with DSD requires understanding of gonadal and germ cell development, which in turn requires a combination of clinical studies and experimental models, including a range of established in-vivo and in-vitro approaches [2,3]. We will discuss the clinical and experimental evidence for fertility potential and options for fertility preservation across a range of DSDs.
