NCT Number: NCT04602962
This study analyses clinical data prospectively collected for over a decade in several clinical databases. Electronic medical records are available since 1998.
Since 2011 the subgroup of patients that undergo fertility preservation are invited to participate in a prospective study aiming at long-term follow-up after fertility preservation for oncologic and non-oncologic conditions.

In this study, the investigators aim at analyze the treatment outcomes of patients with infertility, their clinical characteristics and biochemical parameters aiming at identifying predictors for the treatment outcomes.
For the cohort of patients that have undergone fertility preservation at Karolinska University Hospital, the investigators aim at investigating efficacy and safety of the procedures.
The data can be expanded by using additional databases such as the Regional Cancer Registry and other registries.
Analysis of data collected will allow the investigation of efficacy and safety of fertility preservation, identification of predictors for fertility outcomes,prediction of future activities and costs of the procedures.
