What Happens if You Block Sperm From Coming Out?

What happens if you block sperm from coming out? This is a common question among many men.

When men ejaculate, they might temporarily or permanently stop the sperm from coming out of their penis.

This can happen either intentionally or due to certain medical conditions.

Others may suffer from a health problem that stops sperm from leaving the body. 

There is no evidence that sperm blocking causes damage or has harmful side effects. 

Unejaculated sperm is not harmful and does not collect in the body. The body reabsorbs it.

This article will examine why people do not ejaculate, its potential benefits, and what happens if you block sperm from coming out.

What happens if you block sperm

Not ejaculating, whether willingly or owing to specific medical circumstances, usually offers no substantial health hazards.

However, there may be specific adverse effects or considerations to be aware of:

Retrograde Ejaculation

Blocking the release of sperm might result in Retrograde Ejaculation in some situations. 

This happens when sperm gets diverted into the bladder rather than discharged through the penis. 

The obstruction might cause sperm to move backward into the bladder rather than forward through the urethra. 

While Retrograde Ejaculation is not dangerous, it can have an impact on fertility since the sperm cannot reach the reproductive system of the partner.

Pain or discomfort

Preventing the release of sperm during ejaculation may result in genital pain or discomfort.

The pain may result from the accumulation of pressure in the reproductive organs without the release of semen.

Backflow issues

Blocking the escape of sperm during ejaculation might cause pressure-building problems. 

This can result in leakage of sperm into the bladder or the formation of abnormal pathways within the reproductive system.

Infection risk

If the obstruction is not appropriately handled or cleared, the risk of infection increases. 

Bacteria can develop in stationary sperm or sperm, potentially leading to illnesses in the reproductive organs.

What are the possible causes of not ejaculating

People can decide to restrict ejaculation temporarily or permanently for various reasons, or they may have a disease that prevents sperm from exiting the body.

The possible causes of not ejaculating include, preventing ejaculation intentionally, Anejaculation, Retrograde Ejaculation, and Vasectomy.

Preventing ejaculation intentionally

Edging, a method of preventing an orgasm during masturbation or intercourse, may cause people to delay ejaculation

According to the International Society for Sexual Medicine (ISSM), this may increase the intensity and pleasure
of orgasm for some individuals.

Edging can be used to control Premature Ejaculation as well.

Orgasms without ejaculation may be a part of some methods, like Karezza

This method emphasizes specific postures and techniques, breathing, and meditation.  

The goal is to induce orgasm without ejaculating to maintain sexual activity.

If you are having persistent ejaculation problems, seek the advice of a healthcare expert.


When a man cannot ejaculate sperm, this is known as Anejaculation.

It can occur as a result of the following factors:

  • Spinal cord damage or pelvic region
  • Infections
  • Some medicines, particularly antidepressants
  • Pelvic surgery, which may affect the pelvic nerves
  • Testicular cancer treatments that necessitate lymph node removal
  • Certain diseases that affect the nervous system, such as Parkinson’s disease 
Not releasing sperm for a long time can lead to genital soreness or discomfort.

Retrograde Ejaculation

Retrograde Ejaculation happens when sperm is deflected back into the bladder instead of being ejected from the penis during ejaculation.

This can occur due to certain medical disorders, operations, or medications that interfere with the normal functioning of the muscles and valves that govern sperm release. 

When people with Retrograde Ejaculation undergo orgasm, they may create little or no semen.

While Retrograde Ejaculation is not harmful to one’s health, it can impact fertility. 

Because the sperm are not discharged from the body, the odds of establishing a pregnancy through sexual intercourse get reduced.

Vasectomy prevents sperm from coming out

By getting a Vasectomy, some people may permanently prevent sperm from coming out. 

Surgically closing the sperm canals this treatment prevents sperm from ejaculating.

To prevent a female sexual partner from becoming pregnant, many people choose Vasectomy as a type of birth control.

Treatments for sperm blockage

The course of action for sperm blockage is determined by the location and source of the blockage.

Some of the common treatment includes surgery, Transurethral Resection of the Ejaculatory Duct (TURED), Epididymal Sperm Aspiration (PESA, MESA), and In Vitro Fertilization (IVF) with Intracytoplasmic Sperm Injection (ICSI).


Surgical intervention can be utilized to remove or bypass the obstruction in some circumstances. 

To reestablish sperm flow, treatments such as Vasovasostomy (reconnecting the vas deferens) or Vasoepididymostomy (connecting the epididymis to the vas deferens) may be used.

Transurethral Resection of the Ejaculatory Duct (TURED)

This surgery is used to remove blockages from the ejaculatory ducts, which are the tubes that transport sperm from the seminal vesicles to the urethra.

Epididymal Sperm Aspiration (PESA, MESA)

If the blockage is in the epididymis, sperm can be extracted straight from the epididymis using a needle aspiration method. 

This sperm can subsequently be utilized in assisted reproduction procedures like Intracytoplasmic Sperm Injection (ICSI).

In vitro fertilization (IVF) with Intracytoplasmic Sperm Injection (ICSI)

When the obstruction cannot be physically corrected or circumvented, in vitro fertilization (IVF) with intracytoplasmic sperm injection (ICSI) can be a viable therapy option. 

To promote fertilization, sperm is directly inserted into the egg during this process.


To extend a sexual encounter, some people intentionally prevent sperm from coming out.
However, several medical issues might make it difficult to ejaculate.

But what happens if you block sperm from coming out?

Not ejaculating, whether deliberately or due to unique medical situations, typically poses no significant health risks. 

However, there may be special side effects or precautions to keep in mind.

Retrograde Ejaculationis one effect of purposefully or unintentionally preventing sperm from emerging during ejaculation. 

Additionally, it may cause genital soreness or discomfort, possible backflow problems, and a higher risk of infection. 

There doesn’t seem to be any evidence that preventing sperm from leaving the body is harmful. 

Any sperm that doesn’t escape the body is reabsorbed by it.

People should consult a doctor for any worries regarding their fertility or sexual health.

Frequently Asked Questions

Is keeping sperm for an extended time beneficial?

No. There is no scientific evidence that intentionally retaining sperm inside the body for an extended time gives any meaningful benefits. 

Sperm cells have a finite lifespan and are created indefinitely by the testes. If they are not ejaculated, the body usually reabsorbs them.

If a male doesn’t release sperm, what happens?

If a male doesn’t release sperm, it may cause genital soreness or discomfort, possible backflow problems, and a higher risk of infection.

What are the advantages of abstaining from ejaculation for 30 days?

Little scientific study has focused on the benefits of not ejaculating for 30 days. 

Proponents of sperm preservation or refraining from ejaculation for lengthy durations may argue that abstaining from ejaculation might reduce stress.

It can also lead to increased motivation and enhanced self-esteem and confidence.

When do males stop having ejaculations?

While there is no definitive age at which male ejaculation ends, it has been claimed that it may occur in a man’s late forties or early fifties. 

However, it should be noted that this is not a universal norm, and some men may continue to ejaculate at a later age.

What happens if a man releases sperm every day?

Ejaculating frequently won’t exhaust the body. 

The body produces millions of sperm every day, although it takes an average sperm 74 days to mature fully. 
Men with average, healthy sperm counts shouldn’t be concerned about the consequences of frequent ejaculation.
