Collecting Sperm According to Halacha

Information Sheet: Halachic sperm collection


In the course of fertility diagnosis and treatment, it may become necessary for the husband to provide at least one sample of his semen to a laboratory for analysis. Given the prohibition against ejaculation outside of intercourse, this seemingly simple step presents serious halachic challenges. This article examines those difficulties and possible solutions. It should be noted that any individual case requires consultation with a knowledgeable Rabbi. We will examine:

  • The methods of sperm collection.
  • The halachic problems inherent in those methods.
  • Ways around the halachic issues.
  • Ranking the various methods halachically.

The process

The typical method for obtaining a semen sample for laboratory testing is masturbation. For men unable to achieve or sustain an erection, the process might also include a vacuum system (VES) or vibrator.  See the article on erectile dysfunction for more information.

Halachic considerations

The chief halachic impediment to the standard method of extracting semen is that doing so anywhere but inside one's wife is prohibited, “wasting seed.” Even withdrawing the penis to ejaculate outside the vagina (coitus interruptus) is forbidden. Jewish mystical sources take an even dimmer view of masturbation, identifying it as one of the worst sins.

Two ways around the prohibition appear in the halachic literature: redefining wastage and collection from within the vagina. With wastage interpreted not to include procurement of sperm for reproductive purposes, the prohibition can be bypassed. However, since many prominent authorities object to that redefinition, collection from within the vagina following intercourse is preferred. That might not be possible or practical under all circumstances.

Preferred methods

The Tzitz Eliezer (Vol. IX, 59:1.2) establishes a hierarchy of methods for obtaining a semen sample. In order from most preferable to least, each successive method may be used only if the ones above it prove impractical:

  1. Post-coital collection from within the vagina (preferably by a female physician or nurse).
  2. Collection directly after coitus interruptus.
  3. Collection from a special condom used during intercourse. These condoms, which unlike commercial condoms are not treated with spermicide, are available through Puah and should only be used according to Rabbinical guidelines.
  4. Collection from a receptacle placed inside the vagina before intercourse.
  5. Masturbation through mechanical stimulation.
  6. Masturbation through self-stimulation.


Although the halacha prohibits ejaculation outside the woman's body, poskim have found some flexibility in this prohibition. The above hierarchy of methods should serve as a rough guide to permissible courses of action, but a Rabbi must be consulted in each case.
