Micro-TESE and Advanced Male Procedures
For many couples facing infertility, the journey begins with the assumption that the challenge lies with the woman. Yet in reality, male factors account for a significant portion of fertility difficulties. Of the roughly 15% of the population experiencing infertility, about 40% of cases involve a contributing factor from the man's side.
In some of these cases, the issue is severe: there are no sperm cells at all present in the ejaculate. This condition, known as azoospermia, can feel discouraging. But it does not always mean that a man cannot father biological children. In many situations, sperm production is still occurring inside the testicle, and advanced procedures can retrieve those sperm for use in fertility treatment.
This article explains how sperm is normally produced, why it may be absent from the ejaculate, and the advanced surgical procedures — including biopsy, aspiration, and micro-TESE (microdissection) — that can help. We also address the important halachic considerations these procedures raise. Our advisors at PUAH can help guide you through every step.
Key Points
Male factors contribute to roughly 40% of infertility cases.
Sperm quality is measured by three values: concentration, motility, and morphology (shape).
Even when no sperm appears in the ejaculate, sperm production may still be occurring inside the testicle.
Three main retrieval methods exist: testicular biopsy, testicular aspiration, and microdissection (micro-TESE).
These procedures raise important halachic questions related to p'tzua daka that should be discussed with rabbinic guidance.
How Sperm Is Normally Produced
In a healthy man, sperm is produced inside tiny structures called tubules within the testicle, and it is produced in enormous quantities. The sperm is then stored in the epididymis. When sperm is released, it travels from this storage area through the sperm duct (vas deferens) and out of the body.
When there is a problem with sperm production, one or more of three key measurements is affected:
Concentration — the number of sperm cells in the semen.
Motility — how well the sperm move.
Morphology — the structure or shape of the sperm.
In extreme cases — whether due to a genetic problem or another cause — there are no sperm at all in the semen. When this happens, doctors first confirm that the man is able to function normally in marital relations. Once that is established, the next step is to determine whether sperm can be retrieved directly from the testicle itself.
Why Sperm May Be Missing From the Ejaculate
The absence of sperm in the semen does not necessarily mean that no sperm is being produced. There are two important possibilities to consider:
A blockage: Sperm production may be completely normal, but a blockage in the sperm duct prevents it from coming out.
Low-level production: Sperm may be produced, but at a level too low to reach the ejaculate. Even so, sperm may well be present in the epididymis or in the testicle.
In both situations, retrieving sperm directly from the source can make biological parenthood possible.
Three Methods of Sperm Retrieval
1. Testicular Biopsy
In a biopsy, the doctor removes a portion of testicular tissue and searches it for sperm cells. Even when these sperm are not fully developed, they can be used for in vitro fertilization through a technique called micromanipulation (ICSI), in which a single sperm cell is injected directly into an egg to achieve fertilization.
Advantage: Because a quantity of tissue is removed, there is a higher likelihood of finding sperm.
Disadvantage: The procedure causes injury to the testicle. When the testicle is small, the procedure can only be repeated a limited number of times. There is also a risk that if the surgeon removes tissue from an area that is actively producing sperm, the procedure itself may worsen the testicle's already reduced function.
2. Testicular Aspiration (Needle Aspiration)
In aspiration, a very fine needle is inserted into the testicle to draw out the fluid inside. Sperm cells can sometimes be found within this fluid.
Advantage: The injury to the testicle is minimal, and recovery time is short.
Disadvantage: Success is difficult to predict. Because the surgeon cannot see where the needle is reaching, the procedure is somewhat like working in the dark.
3. Microdissection (Micro-TESE)
In microdissection, the testicle is opened and the tubules are exposed. Using a microscope, the surgeon can identify and remove a very small amount of tissue from a tubule that appears especially "full" or healthy, increasing the chance of finding sperm.
Advantage: The surgeon works under magnification deep within the testicle and can actually see what is being removed, allowing for precision.
Disadvantage: While it was once thought that this method caused no injury, it appears there can be damage to blood vessels, which in turn affects the testicle. A further drawback is that micro-TESE is performed in only a small number of centers worldwide. In Israel, very few medical centers offer the procedure, and where it is available, the cost is very high.
Halachic Perspective
Because these surgical procedures involve cutting, perforating, or removing testicular tissue, the question of whether they create a halachic status of p'tzua daka is a serious and nuanced one. The answer may depend on which procedure is used, the extent of the intervention, and which view of p'tzua daka one follows. These are not questions to be resolved alone.
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 a semen analysis shows no sperm, or if you have been told you may need a surgical retrieval procedure, this is the time to seek both medical and halachic guidance. Each method carries different benefits, risks, and halachic implications, and the right choice depends on your individual situation.
PUAH's team of doctors and rabbis specializes in exactly these situations. We can help you understand your diagnosis, connect you with the right specialists, and ensure that your treatment is carried out in a way that is both medically sound and halachically guided. Reach out to PUAH before making decisions about advanced male procedures.
Summary
The absence of sperm in the ejaculate does not always mean the absence of sperm production, and procedures such as biopsy, aspiration, and micro-TESE can retrieve sperm for use in fertility treatment. Each method has distinct advantages and drawbacks, and each raises important halachic questions concerning p'tzua daka. With proper medical and rabbinic guidance, many couples in this situation can move forward with hope.
