Scientists recently have generated human Primordial Germ Cells (PGCs) out of stem cells. Thereby what has been just possible in mice is put in reach for humans: Implanting PGCs, from which egg or sperm cells can develop.
Thus in future men with men, women with women, or both with themselves could conceive a child. In the actual experiment of Israeli and British scientists artificially modified stem cells, so-called induced pluripotent stem cells (iPS cells) were used to obtain the germ cells.
Autologous stem cells could thus also revolutionize reproductive medicine and solve the problem of decreasing fertility in the Western world! We keep you informed.
