Sperm Donation in Halacha
For couples facing male infertility, the question of sperm donation can be one of the most emotionally and halachically complex they will ever encounter. It touches on deeply personal hopes for building a family, while raising serious questions about lineage, identity, and Jewish law.
In the past, when a husband's semen analysis showed extremely low or absent sperm, donor sperm was often the only available path to pregnancy. Today, medical advances have dramatically changed this picture. With in vitro fertilization (IVF) and surgical techniques for extracting sperm directly from the testicles, many couples who once had no options can now conceive using the husband's own sperm. As a result, the need for sperm donation among married couples has greatly narrowed.
Still, there remain situations where no sperm cells can be found, even after surgery, or where treatment fails. In these cases, the difficult question of sperm donation returns. This article explains the medical background and the central halachic considerations, drawn from the guidance of PUAH.
The Medical Background
About one percent of all men have no sperm cells at all in their semen analysis — a condition known as azoospermia. Even in these cases, pregnancy is often achievable through surgical procedures that extract sperm directly from the testicles, which can then be used in IVF.
However, there are still cases where:
Surgery does not recover any sperm cells.
Sperm cells are recovered, but the fertilization attempts fail.
When all medical avenues using the husband's own sperm have been exhausted, the question of using a donor may arise. This is the point at which halachic guidance becomes essential.
Halachic Perspective
The Concern of Mamzerut (Illegitimacy)
Some halachic authorities were concerned that when a married woman becomes pregnant from the sperm of a man who is not her husband, this could create a status of mamzerut for the child — even though the pregnancy did not result from a forbidden relationship.
In practice, most halachic authorities do not consider the child a mamzer. However, even according to this lenient view, one should not knowingly perform an act that some authorities believe creates mamzerut. For this reason, the concern is taken seriously when deciding whether to proceed.
The Problem of an Unknown Father
Under current practice in the State of Israel, and other places, donation is anonymous. There is no way to know the identity of the donor. According to halacha, it is forbidden to bring about a situation in which a child is born whose father is unknown.
This raises serious concerns, including the future possibility of unknowingly marrying a close relative.
The Status of a Child With a Non-Jewish Father
An important halachic principle helps clarify some of these questions. A child born to a Jewish mother and a non-Jewish father is considered a fully valid Jew — even if the mother is married according to Jewish law. Such a child is not a mamzer.
Furthermore, a Jew whose father is not Jewish is considered, halachically, as one who has no father. Therefore, even if the identity of a non-Jewish donor is unknown, the concerns regarding an unknown father do not apply in the same way.
Despite this, most halachic authorities prohibited sperm donation even from a non-Jewish donor. A number of important authorities did permit donation from a non-Jewish man in cases where there was a concern for the wholeness of the family — provided the husband agrees to raise the child as his own in every respect.
Why PUAH Does Not Issue a General Ruling
Because of the great halachic and personal complexity involved in such a decision, the consulting rabbis at PUAH do not give a general ruling on questions of sperm donation. Instead, we provide an individualized ruling only after a personal meeting with both spouses, and after receiving the full picture of their medical and personal circumstances.
Every couple's situation is different. The right path can only be determined with full knowledge of the medical realities, the emotional needs of the couple, and the relationship between the spouses.
Specific questions should be discussed with a qualified rabbinic authority. Our team at PUAH is available to help you navigate these questions.
When to Speak With a Professional
If you and your spouse are facing male infertility, you may want to consult professionals before considering sperm donation. In many cases, newer medical techniques can make donation unnecessary. A fertility specialist can clarify whether surgical sperm extraction or other treatments are options for you.
Equally important is rabbinic guidance. Because sperm donation involves both serious halachic concerns and significant emotional weight for a marriage, it should never be approached without careful, personal consultation.
PUAH's team of doctors and rabbis specializes in exactly these situations. We can help you understand your medical options, weigh the halachic considerations, and make decisions together as a couple.

Summary
Medical advances have greatly reduced the need for sperm donation among married couples, yet difficult cases still arise. Halacha raises serious concerns about lineage, an unknown father, and the integrity of the family, leading most authorities to prohibit sperm donation — though some permitted donation from a non-Jewish donor in specific circumstances. Because of this complexity, PUAH addresses each case individually, only after meeting personally with both spouses.
