“Wait, we really can’t use a condom?” a kallah (bride) asked me during a class.
In many Orthodox communities, a kallah is obligated to learn the laws of taharat hamishpacha (family purity) before marriage. This Jewish commandment defines when a married couple may be physically intimate and when they must refrain,this is according to the niddah status, most often associated with a woman’s menstrual cycle. As a woman prepares for marriage, this learning often includes the practical rhythm of the cycle, the days of separation, and the process that ends with immersion in the mikveh, the ritual bath, before resuming physical connection.
For me, an important aspect of these classes is not just to touch upon the halacha (Jewish law), but to have an honest, grounded conversation about sex in Judaism, and about “kosher” birth control, what’s permitted, and why.

What are the Jewish laws involving sex and intimacy?
The first mitzvah (commandment) we receive in the Torah is “be fruitful and multiply.” Because of that, many assume that in Judaism, birth control must be forbidden.
But there is another aspect of Jewish tradition that is often left out of the conversation: the mitzvah of onah, the husband’s obligation to ensure his wife’s sexual wellbeing and pleasure and to maintain a loving, intimate relationship. We learn this from the Torah when a man takes a woman as his wife (Exodus 21:10). He is obligated to provide three things: support, which means a home and food, clothes, and onah, which means time or season, which we understand to mean intimacy. In other words, sex is treated as meaningful and even holy in its own right, not only for the means of having children.
That framework is a large part of why many rabbinic authorities permit delaying pregnancy when there’s a plan, and the couple has a sincere intention to have children when they’re ready. In those views, contraception isn’t automatically “anti-mitzvah.” It can be a tool that a couple uses to build stability, health, and a strong relationship so they can eventually bring children into a home that’s ready for them.
Jewish law and contraception
It is important to add that every rabbi is different, and some are more stringent and will prohibit birth control entirely, while others will limit the use to a certain period of time, depending on the particular couple and their situation. I was introduced to someone whose rabbi permitted her to use birth control for three months. In general, though, most rabbis are open to contraception as long as there is an intent to have children when the couple is ready.
And that brings us back to the question behind the question: While birth control is permitted, some methods are considered kosher, whereas others are not. What determines this?
Beyond the mitzvot of ‘be fruitful and multiply’ and onah, there’s another concept in Judaism that comes up in conversations about contraception: hotza’at zera levatalah, commonly translated as “spilling the seed.”
This concept is often linked to the story in Genesis 38. Yehuda’s son, Onan, is killed by God because he was having relations with his wife Tamar, but deliberately prevents conception by ”spilling his seed.” Over time, many rabbinic authorities understood this story, together with later halachic sources, as a foundation for the prohibition against intentionally wasting seed.
In contemporary conversations, many educators still take the value seriously while emphasizing the core message Judaism is trying to cultivate: intimacy within marriage is meant to be intentional, respectful, and sanctified. Especially when teaching young people, the goal isn’t to weaponize “spilling the seed” to shame people for exploration in adolescence; the focus today is on guiding toward healthy and meaningful relationships, with sensitivity to the realities of growing up.
Which contraception methods are permitted in Judaism?
Halachically, though, this concern is one reason certain birth control methods are treated differently from others. Methods that block semen during intercourse are often prohibited. This is why condoms are not a regular birth control method used by many observant Jews. (That said, it is important to note that there are certain situations in which it is permitted. It’s worth consulting with a doctor and a rabbi if necessary.)
We also take into account the concept of “be fruitful and multiply.” Jewish law generally prefers birth control methods that are temporary and reversible; this is why permanent medical forms of contraception, such as tying tubes or a vasectomy, are prohibited in Jewish law, except in certain medically complex cases where a rabbi or a doctor must weigh risks, alternatives, and the couple’s situation.
So what is permitted?
The preferred options are methods that are used on the woman’s side and don’t involve “wasting seed” concerns in the same way, preserving the possibility of future pregnancy. Many rabbis therefore permit, and often recommend, a range of hormonal and non-hormonal options, depending on the couple’s needs.
These include:
- Fertility awareness methods (FAM)
- The pill
- IUDs (copper or hormonal)
- NuvaRing
- Patch
- Implant (rod/Implanon or similar)
- Spermicide (including VCF films)
- Diaphragm
- Sponge
- Emergency contraception (“morning-after pill”) (not as a regular method, but generally permitted in)
There are many different methods that a woman can decide to use as birth control, and she might decide to change from one to another and try multiple different ones, and that is perfectly fine.
The bottom line is that birth control is kosher to use. Each community approaches this topic differently, and each couple’s health, goals, and life circumstances are unique. Therefore, I recommend consulting with a rabbi and a medical professional to find the one that suits you best.
