fertility preservation treatment methods
The following treatment strategies, which are tailored according to the individual situation, are recommended and performed by members of the FertiPROTEKT network e.V..
ovarian stimulation to collect egg cells
The aim of stimulating egg cell maturation (stimulation) is to collect mature eggs that can be frozen either fertilized or unfertilized.
CRYOCONSERVATION OF EGG CELLS
Fertilized or unfertilized egg cells can be frozen (cryopreserved) before the start of chemotherapy
Removal and transplantation of ovarian tissue
Ovarian tissue can be removed before chemotherapy or radiotherapy, cryopreserved (frozen) and, in the case of a loss of ovarian function, later retransplanted to restore fertility.
CRYOPRESERVATION OF OVARIAN TISSUE
Ovarian tissue can be frozen (cryopreserved) before chemotherapy and/or radiotherapy.
GNRH agonists and combined hormonal contraceptives (birth control pills)
GnRH agonists (GnRHa) are medicines that temporarily prevent the release of the hormones LH and FSH by the pituitary gland, which normally stimulate oocyte maturation and hormone production in the ovaries.
Relocation of the ovaries
The aim of moving the ovaries (transposition of the ovaries) is to retain their function despite planned radiotherapy. The goals are the preservation of hormone production and also the possibility of pregnancy after oncological treatment
cryoconservation of sperm and testicular tissue
Male germ cells (sperm) can be cryopreserved (frozen) before chemotherapy or radiotherapy and, in the case of a loss of function of a male patient’s gonads (testes), are used to conceive his own child.
