Markus K. didn’t set out in life to father 24 children. He set out to be a priest — but that dream came to an end in 1994, when someone reported to his seminary that he was gay, and they threw him out. But it was then, he told Irene Kiebner, that he saw an bulletin board note from a lesbian seeking a sperm donor. He said he met the couple in 2003 before agreeing to donate, but that they successfully conceived a boy after only two tries. The women’s midwife eventually became the mother of K.’s fourth child, as word spread in “the scene” that K.’s help was “uncomplicated” and the women conceived quickly.
