Additional children through IVF

24 November, 2002


I underwent in vitro fertilization and gave birth to twins, a boy and a girl. According to halacha we have fulfilled the commandment of peru u revu. Is it permissible to undergo IVF again in order to conceive?


We appreciate the sensitive nature of this question.

As you are probably already aware, in vitro fertilization (IVF) raises certain halachic questions such as the method of obtaining the sperm and the degree of medical intervention needed for the wife. However, these considerations are outweighed, according to most rabbinic authorities, by the Torah commandment of “be fruitful and multiply” (pru u rvu). There is also a widespread halachic consensus to allow a couple to also undergo IVF in order to fulfill the rabbinic commandment of continuing to have children.

It would be best to ask a direct question of your rabbi, who is most familiar with your personal circumstances. If you do not have access to a rabbi to answer this question and desire a personal adjudication, please get back to us either via the website or our telephone hotline so we can help you. Or you might find it helpful to arrange a free consultation with a Yoetzet Halacha Fertility Counselor, details here.
