Male Factor Infertility: Diagnosis & Testing

When a couple struggles to conceive, it is natural to wonder where the difficulty lies. Many people assume that fertility challenges rest mainly with the woman, but this is not the case. In fact, between 30% and 50% of fertility difficulties are connected to problems with the man's sperm. For this reason, evaluating the man's fertility should be one of the first steps in any fertility investigation.

The good news is that male factor testing is relatively simple, painless, and informative. A single test can reveal a great deal about whether the sperm is functioning as it should, and it can save a couple months of uncertainty. Understanding what these tests measure—and what the results mean—can help you approach the process with confidence rather than anxiety.

At the same time, sperm testing carries unique halachic considerations that other medical tests do not. We at PUAH have spent decades helping couples navigate both the medical and the religious dimensions of this testing, so that you can get the answers you need while remaining faithful to halacha.

Why Testing the Man Comes First

A semen analysis is the basic, first-line test for evaluating male fertility. Because such a large share of fertility difficulties trace back to sperm quality, it makes sense to check this early. The test is non-invasive for the man, the results come back quickly, and they give doctors a clear picture of an important piece of the puzzle.

Identifying a male factor early can also spare the woman from undergoing more complex and invasive tests before they are truly necessary. A simple semen analysis is often the most efficient way to begin.

What a Semen Analysis Measures

A semen analysis (sperm test) looks at several different measurements. The most important are described below.

Sperm Concentration

This is the number of sperm cells per milliliter of fluid. A result above 15 million cells per milliliter is considered normal.

Motility

This measures the percentage of sperm cells that are moving, and the quality of that movement. A result of more than 40% of cells in motion, or more than 25% showing rapid forward (progressive) movement, is considered normal.

Morphology (Shape)

This measures the percentage of sperm cells with a normal shape. Today, a result of 4% or more normally shaped cells is considered normal.

Additional Measurements

The laboratory also examines other factors, such as the volume of the semen and its acidity (pH level). In certain situations, these additional measurements can carry real significance for diagnosis.

Halachic Perspective

Because of the prohibition against the wasteful emission of seed (hotza'at zera levatala), a sperm test is considered halachically complex. There are differing approaches among the poskim regarding whether, when, and how such a test should be performed. As a practical matter, performing any sperm test requires a halachic ruling from a posek who is well versed in both the halachic and medical aspects of the subject.

Even once a sperm test has been permitted, there are several halachically acceptable methods for carrying it out. Each has its place, and the right choice depends on your circumstances.

Vaginal Collection (Post-Coital, "PCT")

This is usually the first method for a couple committed to halacha. The couple has normal marital relations, after which the wife collects a portion of the semen that is naturally released from her body, using a sterile cup. The cup must be brought to the laboratory within one hour.

This is the best method from a halachic standpoint, because it is based on normal marital relations. While the method of collection can affect the reliability of the results, in most cases the impact is not significant, and the test is considered reliable enough for an initial diagnosis. When the result comes back normal, this is usually sufficient and no further test is needed. When the result is not normal, an additional test is generally required, and you should consult a posek about whether and how to perform it.

Sterile ("Halachic") Condom

This method is chosen when the vaginal collection raises a concern about a sperm problem, or when sperm is being provided as part of a fertility treatment. The couple has normal marital relations using a special condom that contains no spermicide and is stored to preserve its sterility (a sterile condom), with a small hole made at its tip. Afterward, the husband removes the condom containing the semen, places it in a prepared sterile cup, and the cup is brought to the laboratory within one hour.

It is important to know that the sterile condom is not sold in regular pharmacies. It is available only in dedicated locations, such as certain fertility laboratories or through PUAH. Note also that while some refer to this as a "halachic condom," that name does not constitute a blanket permission to use it. In some cases, this additional test can be combined with a fertility treatment in which the sperm is also used toward the possibility of pregnancy. When done under proper halachic supervision, this approach has halachic advantages, though it is not always practical.

Withdrawal Method (Collection by Withdrawal)

This method is reserved for unusual cases in which a couple cannot perform the test using a sterile condom, even after receiving proper guidance. The couple has normal marital relations, and just before emission the husband withdraws and emits into a prepared sterile cup.

According to most poskim, this method is less preferable halachically than the sterile condom (and it is also considered less successful medically). Still, because the seed is given within the framework of marital relations, most poskim permit it when a couple cannot give a sample using the sterile condom.

A Note on Manual Collection

Producing a sample by hand is considered highly problematic halachically, even within a fertility investigation. Because a sperm test is not limited to a particular time of the month, it is usually possible to perform the test using one of the methods described above. Even in unusual cases—such as an unmarried man who has received permission to be tested—there are ways to perform the test using a special device known as PVS, which produces a sample without the need to emit seed directly by hand.

For all these reasons, methods such as the withdrawal method or manual collection are reserved for exceptional cases only, and only after receiving explicit permission from a posek who is an expert in this area.

When to Speak With a Professional

If you and your spouse have been trying to conceive without success, it is wise to begin the evaluation early, and a semen analysis is often the simplest first step. You should also reach out for guidance if your results come back abnormal, if you are unsure which testing method is appropriate for you, or if you need to obtain a sterile condom or arrange testing within a fertility treatment.

PUAH's team of doctors and rabbis specializes in exactly these situations. We can help you understand your results, choose a halachically sound testing method, and connect you with appropriate medical care. Reach out to PUAH—our advisors are here to help.

Summary

Male factor issues account for a large share of fertility difficulties, and a simple semen analysis is the best first step in evaluating them. The test measures sperm concentration, motility, and shape, along with other factors. Because sperm testing raises real halachic questions, every test should be done with rabbinic guidance and using one of the approved methods.
