Hi, Keith —

Thanks for your question.

I believe the Holy Father's Encyclical on the Gospel of Life, Evangelium Vitae, will help answer your question. He talks about in vitro fertilization, in and around, paragraph 63.

I also found the following articles, which appeared to be pretty good.

• In-Vitro Fertilization Examined From a Catholic Perspective.
• In Vitro Fertilization—Where Does the Catholic Church Stand?
• Begotten Not Made: A Catholic View of Reproductive Technology
  by John M. Haas, Ph.D., S.T.L.
• Instruction on Respect for Human Life in its Origin and on the Dignity of Procreation: Replies to Certain Questions of the Day from the Congregation for the Doctrine of the Faith, February 22, 1987

If you have any other questions, just reply via e-mail.
