Turner syndrome is a genetic disorder (inherited disease) in which there is a loss of an X chro­mo­some or a restric­tion of its function. In Turner syndrome, the decision about fertility pre­serving methods can only be made based on various aspects of a patient’s indi­vidu­al situation. There are also questions that cannot be answered or answered only inad­equately by studies at present.

The decision for or against fertility pre­ser­va­tion should not only be based on the one-time meas­ure­ment of the AMH level, but should take into account the AMH level during the course, the indi­vidu­al findings of the genetic exam­in­a­tion as well as the maternal risks during pregnancy. The following points summarize some relevant aspects:

- Fertility-pre­serving inter­ven­tion is only useful if the health of the woman with Turner syndrome allows a sub­sequent pregnancy.
— It is important to dis­tin­guish between Turner syndrome with a monosomy versus a mosaic or struc­tur­al abnor­mal­ity (aber­ra­tion). Regard­less, the presence of ovarian function must be considered.
— In the case of a normal ovarian reserve, it may be possible to wait with regular check-ups.
One way to facil­it­ate the patient’s decision after the con­sulta­tion regarding fertility pre­serving methods is the “Decision Aid” linked here.

It is a digital decision aid developed by psy­cho­lo­gists, psy­cho­ther­ap­ists and repro­duct­ive physicians.

Detailed inform­a­tion and a bib­li­o­graphy can be found in the Fer­ti­PRO­TEKT booklet “Indika­tion und Durch­führung fer­til­ität­s­pro­tekt­iver Maßnahmen bei onko­lo­gis­chen und nicht-onko­lo­gis­chen Erkrankun­gen”, 2nd revised edition 2020, which was written by members of the Fer­ti­PRO­TEKT Netzwerk e.V. and is available free of charge (in German).
