Judaism approaches IVF with the tradition's characteristic combination: a commandment to pursue, technical law to apply, and a compassion mandate for the suffering couple. The first commandment — peru u'revu, 'be fruitful and multiply' (Genesis 1:28) — makes fertility treatment not merely permitted but for many authorities a mitzvah-furthering act; and the patriarchal narratives (Sarah, Rachel, Hannah — all barren, all answered) give infertility a sacred literature of weeping and prayer that rabbis cite when counseling couples. The halakhic questions are practical: third-party gametes are generally prohibited (lineage and mamzer-avoidance), though some authorities discuss egg donation differently since Jewishness traditionally follows the mother — poskim split on whether the genetic or gestational mother is determinative, and couples are directed to their own rabbi; embryo status — the Talmud's statement that the embryo before 40 days is 'mere water' (Yevamot 69b) underlies lenient rulings about early embryos, though destruction is not undertaken lightly; and halakhic supervision (a mashgiach for lab mix-ups — there are real cases) exists precisely because Jewish law takes identity seriously. The community result: IVF is widespread across Orthodoxy, Israel is a world capital of fertility medicine, and the pain of childlessness is treated as the tradition's own business — 'he remembers the barren woman' is in the holiday liturgy.

あなたがすべきこと
以下の詳細な分析は英語で提供されています。
- If pursuing IVF, ask your clinic about single-embryo transfer and minimizing surplus embryos — the practices every tradition can bless.
- Grieve honestly with your community; infertility is suffered silence in every tradition's scriptures, and support groups exist in churches, mosques, and synagogues.
- Jewish: Coordinate with your rabbi on lab protocols and third-party questions — the community has done this successfully for decades.
- All: Whatever the path, children conceived this way are gifts, not compromises — welcome them without apology.
Repentance: Teshuvah
The Talmud teaches that teshuvah was created before the world itself — Hashem believed in your return before you were born. The gates of return are open now.

Is IVF a sin?
It depends on the tradition, and the differences are deep — but everyone agrees the child is fully a person.

What happens to leftover embryos?
This is the shared ethical weight: surplus creation is discouraged and casual destruction forbidden across the traditions.
This is the shared ethical weight: surplus creation is discouraged and casual destruction forbidden across the traditions. Jewish law treats early embryos leniently but seriously. Practical counsel across traditions: fertilize minimally, transfer all created, decide before creating.
Can we use donor sperm or eggs?
Third-party gametes are the clearest line, and most authorities across the traditions refuse them; ask within your own tradition before the clinic schedule forces the question.
