Aims
The aim of the network is to offer men and women the possibility of seeking advice about scientific information regarding their
fertility
Fertility is the capability to produce offspring through reproduction following the onset of sexual maturity. The fertility rate is the average number of children born by a female during her lifetime and is quantified demographically. Fertili ...

, and to undergo procedures to
protect their fertility. The advice about and the performance of fertility-conserving procedures according to the network’s
code of ethics is non-profit oriented.
Background
As a result of today’s significantly improved prognosis for patients with
cancer
Cancer is a group of diseases involving abnormal cell growth with the potential to invade or spread to other parts of the body. These contrast with benign tumors, which do not spread. Possible signs and symptoms include a lump, abnormal b ...

is increasingly important after overcoming
treatment of the disease. Fears about fertility preservation play an important role for young men and women. The most common types of cancer diagnosed under the age of 40 years are
breast cancer
Breast cancer is cancer that develops from breast tissue. Signs of breast cancer may include a lump in the breast, a change in breast shape, dimpling of the skin, milk rejection, fluid coming from the nipple, a newly inverted nipple, or a re ...

melanoma
Melanoma, also redundantly known as malignant melanoma, is a type of skin cancer that develops from the pigment-producing cells known as melanocytes. Melanomas typically occur in the skin, but may rarely occur in the mouth, intestines, or eye ( ...

cervical cancer
Cervical cancer is a cancer arising from the cervix. It is due to the abnormal growth of cells that have the ability to invade or spread to other parts of the body. Early on, typically no symptoms are seen. Later symptoms may include abnormal ...

non-Hodgkin’s lymphoma
Non-Hodgkin lymphoma (NHL), also known as non-Hodgkin's lymphoma, is a group of blood cancers that includes all types of lymphomas except Hodgkin lymphomas. Symptoms include enlarged lymph nodes, fever, night sweats, weight loss, and tiredness. ...

leukaemia
Leukemia ( also spelled leukaemia and pronounced ) is a group of blood cancers that usually begin in the bone marrow and result in high numbers of abnormal blood cells. These blood cells are not fully developed and are called ''blasts'' or ' ...
. One of the biggest problems in women who have to undergo chemo- or radiotherapy is
premature ovarian failure
Primary ovarian insufficiency (POI) (also called premature ovarian insufficiency, premature menopause, and premature ovarian failure) is the partial or total loss of reproductive and hormonal function of the ovaries before age 40 because of fol ...
(premature ovarian insufficiency) and its associated
infertility
Infertility is the inability of a person, animal or plant to reproduce by natural means. It is usually not the natural state of a healthy adult, except notably among certain eusocial species (mostly haplodiploid insects). It is the normal state ...
. For breast cancer alone, it is assumed that there are ca. 200 patients a year in Germany who wish to conceive. In men, chemotherapy can result in permanent damage to the testicular tissue. Due to advances in
reproductive medicine, a variety of fertility-protective methods are now available. These techniques include administration of
GnRH-agonists,
ovarian stimulation with
cryoconservation of fertilised or unfertilised oocytes, as well as
cryoconservation of ovarian tissue. Relocation of the
ovaries
The ovary is an organ in the female reproductive system that produces an ovum. When released, this travels down the fallopian tube into the uterus, where it may become fertilized by a sperm. There is an ovary () found on each side of the body. T ...

Activity
The Fertiprotekt network has carried out international pioneering work in four areas:
* National, comprehensive care structures in the area of fertility conservation have been created, which also serve as a role model for other countries.
* Treatment recommendations have been created, which allow a standardised and scientific approach.
* So-called
luteal phase stimulation
Stimulation is the encouragement of development or the cause of activity generally. For example, "The press provides stimulation of political discourse." An interesting or fun activity can be described as "stimulating", regardless of its physica ...

s to be started at any time during the menstrual cycle. The procedure of egg-cell collection is therefore considerably shortened, and chemotherapy can be started earlier.
* The combination of
ovarian tissue cryopreservation, directly followed by hormonal stimulation to collect egg cells for
oocyte cryopreservation
Human oocyte cryopreservation (egg freezing) is a procedure to preserve a woman's eggs (oocytes). This technique has been used to enable women to postpone pregnancy to a later date – whether for medical reasons (such as cancer treatment), or fo ...
was first performed by centres in the network. This technique allows a significant increase in the chance of pregnancy.
* The first birth after transposition of ovarian tissue, which was transported to a central cryobank by overnight transport immediately after removal, was achieved by the network. This demonstrated that removed ovarian tissue can be centrally prepared and stored in specialised centres.
Network seminars take place annually. The centres involved are obliged to regularly take part in these annual conferences.
Problems
Some methods, such as cryoconservation of sperm and in-vitro fertilisation (IVF) are well established. Others have only been introduced over the last few years, such as cryoconservation of ovarian tissue prior to chemotherapy for later transplantation and the cryoconservation of unfertilized egg cells. These services are therefore not fully covered by statutory health insurance in Germany.
