German laws addressing reproductive rights are reflective of the societal history of the Country, most notably as it was shaped in the late 1930's and early 1940's.
Third party reproductive is, for the most part, forbidden in Germany. Oocyte donation, embryo donation and surrogacy are strictly forbidden.
Sperm donation is permitted, but are excluded under health insurance. Posthumous donation is not allowed. The donation must be consented to by both partners. Implicit here is that only heterosexual couples will be allowed to participate.
PDG may used to reduce severe sex-linked genetic risks, not for pure gender selection.
Embryo transfers are limited to three. Freezing embryos will be permitted only when the planned transfer is delayed because of a medical issue with the intended mother.
