Abstract

Aim The aim of this official guideline published by the German Society of Gynecology and Obstetrics (DGGG) and coordinated with the German Society of Urology (DGU) and the German Society of Reproductive Medicine (DGRM) is to provide consensus-based recommendations, obtained by evaluating the relevant literature, on counseling and fertility preservation for prepubertal girls and boys as well as patients of reproductive age. Statements and recommendations for girls and women are presented below. Statements or recommendations for boys and men are not the focus of this guideline. Methods This S2k guideline was developed at the suggestion of the guideline commission of the DGGG, DGU and DGRM and represents the structured consensus of representative members from various professional associations (n = 40). Recommendations The guideline provides recommendations on counseling and fertility preservation for women and girls which take account of the patientʼs personal circumstances, the planned oncologic therapy and the individual risk profile as well as the preferred approach for selected tumor entities.

Highlights

  • Introduction to Fertility Protection for PersonsDiagnosed with Oncologic Disease1.2 Importance and problems of fertility protection for persons diagnosed with cancerOncologic therapies often lead to partial or complete impairment of gonadal function in both men and women along with the potential loss of germ cells

  • Whether women develop ovarian insufficiency depends on the radiation dose, the age when the patient was exposed to radiation and the volume of irradiated ovarian tissue

  • Slow freezing is currently recommended for the cryopreservation of ovarian tissue because of the higher efficacy of this method in routine clinical practice [12 – 14]
