Berechnung

IVF: Transferdatum + 266 Tage (bei Tag-5-Blastozyste: + 261 Tage). Praeziser als natuerliche Empfaengnis weil das exakte Datum bekannt ist.

In Deutschland

IVF/ICSI wird von GKV zu 50% uebernommen (3 Versuche, verheiratete Paare). Laender-Zuschuesse: manche Bundeslaender uebernehmen die restlichen 50%.

⚡ CalcWolf Insight

IVF babies have the most precisely documented conception dates of any pregnancies in human history. Every embryo has an exact date and time of creation recorded in the lab. This precision makes IVF due dates accurate to within 1-3 days, versus a 2-week uncertainty window for naturally conceived pregnancies.
