Emily Herx, teacher of literature and language at a Catholic school in Indiana, has filed a lawsuit arising from the school's termination of her contract because she and her husband are using IVF in an attempt to conceive a second child. Herx claims that the Catholic school’s monsignor refused to renew her contract and that he referred to her as a "grave immoral sinner."

Her lawsuit claims that the catholic school 's monsignor refused to renew her contract because of her use of in vitro fertilization. Herx said that the monsignorcalled the treatment an "intrinsic evil," which means no circumstances can justify it. After the birth of her first child, Herx had become medically infertile.
