The PRSS37 gene helps sperm function properly during fertilization. This gene plays an important role in helping sperm move through the female reproductive tract and interact with the egg. If it does not work as expected, sperm may struggle to reach or fertilize an egg, which can lead to male infertility. PRSS37 is mainly discussed in fertility research rather than in everyday public health conversations.
What is a gene?
Genes are segments of DNA that give your cells instructions to make molecules or regulate processes in the body. Some genes carry the information needed to produce proteins, the parts of cells that do much of the work. Other genes mainly control when certain processes happen, where they happen, and how strongly they run. Together, genes affect how the body develops and functions, and they can influence how you respond to food, stress, and medications.

Overview
PRSS37Gene function
What if the gene works
The PRSS37 gene helps sperm work normally. Its protein supports the final steps that let sperm travel through the female reproductive tract and reach the egg. This contributes to male fertility.
Risk
What if the gene does not work
More severe variants in the PRSS37 gene can cause male infertility, often because sperm cannot travel normally through the female reproductive tract. Milder variants may have smaller effects on fertility.
Treatment
What does that mean for your treatment
No PRSS37-specific treatment or drug selection approach is currently established in clinical guidelines. The PRSS37 gene is being studied mainly in reproductive research, including as a possible target for nonhormonal male contraception and as a marker linked to some forms of male infertility.
Gene function
What if the gene works
In the testes, the PRSS37 gene supports the final preparation of sperm for fertility. Its protein becomes part of the sperm surface and helps sperm carry out normal steps needed for fertilization. Understanding how the PRSS37 gene works helps you see how sperm function is supported in everyday reproductive biology.
The PRSS37 gene helps sperm complete important surface changes as they mature in the testes. These changes prepare sperm for the later steps of fertilization.
PRSS37 helps organize key proteins on the sperm surface. This organized coating supports normal sperm function during the journey through the female reproductive tract.
Its protein supports the steps that help sperm reach the egg in natural conception. It also helps sperm stay ready for the first contact needed for fertilization.
What is a variant?
A genetic variant is a minor difference in the DNA sequence within a gene. These differences are common and help shape normal human diversity, including differences in appearance, metabolism, or the way the body responds to environmental influences. Many variants do not cause any noticeable effect and simply represent natural genetic variation. In some situations, though, a variant can change how a gene works more significantly and may contribute to or cause a genetic condition.
Genetic variants
What if the gene does not work
Some PRSS37 gene variants slightly reduce how much PRSS37 protein reaches the sperm surface, while more severe variants can stop the protein from being made or processed correctly. In plain terms, how PRSS37 gene variants affect protein function often depends on whether the DNA change alters folding, stability, or key protein interactions. More disruptive changes are linked to a greater effect on sperm function and can have a stronger impact on male fertility.
How variants are linked to conditions
At this time, PRSS37 gene variants linked to conditions have not been broadly confirmed in routine medical genetics, although research may refine this over time. If you carry a reported change in the PRSS37 gene, the result is best interpreted with your doctor or genetic counselor using your personal and family history.
A variant is not necessarily a diagnosis
Gene variants are a usual part of human biology and are common across the general population. Most do not have a direct effect on health and simply reflect natural differences among people. For many genes, carrying a variant associated with a condition suggests a possible link rather than a certain diagnosis, especially when several genes and environmental factors also play a role. In some situations, though, a single well understood variant in a particular gene is enough to confirm a diagnosis.
Are there things that can increase or change my risk?
There is not yet broadly confirmed evidence on specific factors that increase or reduce health risk related to the PRSS37 gene. If you have a PRSS37 gene change or concerns about fertility or family risk, a doctor or genetic counselor can help explain what it may mean for you.
Inheritance of PRSS37 variants
There is not yet a broadly confirmed disease inheritance pattern for the PRSS37 gene, so answers to how PRSS37 gene variants are inherited remain cautious and may change as research develops. PRSS37 is located on chromosome 7, which is an autosome, so a person inherits one copy of the PRSS37 gene from each parent. This means any variant in this gene can be passed through either side of the family.
What does my PRSS37 result mean for my family?
There is not yet a broadly confirmed inheritance pattern tied to a specific health condition for the PRSS37 gene, though this can become clearer as research grows. If you have a PRSS37 result and want to understand what it could mean for relatives, a doctor or genetic counselor can help explain it in the context of your family history and the exact result.
Genetic information
Genetic testing
How you find out about variants
PRSS37 genetic testing usually uses a blood or saliva sample. A lab reads the DNA in the PRSS37 gene to look for variants and then classifies any change based on current medical evidence. This is how you find out about variants in PRSS37 and whether a result is benign, uncertain, or linked to a health condition.
When should I consider getting a genetic test?
There is not yet a broadly established reason to test the PRSS37 gene on its own in routine medical care. Decisions about genetic testing are usually based on fertility history, other test results, and family history, together with a doctor or genetic counselor.
A genetic result is only one part of your health story
Genetic results can provide useful information, but how much they reveal varies by the condition and the type of variant involved. Lifestyle, environment, age, and medical history are among the many factors that influence how the body functions over time. In some conditions, especially those affected by many genes, genetic information provides context rather than certainty and is best considered alongside other parts of care. In other situations, a genetic result may offer a clear answer. In areas like medication response, genetic results can also help put individual experiences into context.
Pharmacogenetics
How variants shape your response to medicine
Genetic variation can affect how people respond to medicines. Two people can take the same treatment, yet one may get more benefit while the other may be more sensitive to side effects because their bodies absorb, break down, or respond to the drug differently. These inherited differences are common and can influence how strongly a medication works or how well it is tolerated.
What is Pharmacogenetics?
Pharmacogenetics examines how differences in a person’s genes can affect the way they respond to medicines. It focuses on connections between genes and drugs to help explain why the same treatment may work differently from one person to another. For many medications, genes can influence both how strongly a drug works and how the body handles it. This information can support more informed and more individualized treatment decisions.

Drugs influenced by the PRSS37 gene
When should I seek medical advice?
There is not currently a broadly confirmed role for this gene in guiding how medicines are chosen or used, so any concerns about side effects, treatment changes, or your overall health are best discussed with your doctor.
History
PRSS37 entered the scientific literature through research on genes active in the testis and male fertility. Early animal studies, especially in mice, brought it into focus when researchers found that loss of Prss37 was linked to infertility, helping place the gene on the map in reproductive genetics. Building on this early work, scientists expanded their attention to the human PRSS37 gene and to related genes involved in fertilization. Over time, descriptions became more precise as laboratory methods improved and gene sequencing became routine. Unlike genes that reached the public spotlight, PRSS37 has remained better known within fertility research, where it contributes to the longer scientific effort to understand inherited causes of male infertility.
