Anejaculation is a condition that can affect individuals of any age and refers to the inability to ejaculate during sexual activity. It can be a source of frustration, anxiety, and shame for those who experience it and can have a significant impact on sexual relationships. In this lesson, we will examine the possible causes of anejaculation, including both physical and psychological factors, and explore potential treatment options and strategies for managing this condition.

Anejaculation: What Causes It?

Anejaculation can be a complex condition with multiple potential causes, and an individual’s experience may be unique. It can have a variety of causes, which can be physical, psychological, or a combination of both.


Anejaculation is a more common condition among older age groups of men, as the risk of medical conditions such as diabetes, spinal cord injury, or prostate surgery increases with age. Certain medications, such as antidepressants and blood pressure medications, can also interfere with ejaculation. Psychological factors, such as anxiety or depression, can also contribute to anejaculation.

Primary And Secondary Anejaculation

There are different types of anejaculation, including primary anejaculation, which occurs when a man has never been able to ejaculate during sexual activity or masturbation, and secondary anejaculation, which develops later in life after a man has been able to ejaculate normally.

The causes of primary ejaculation can be congenital conditions, psychological factors or medications. Some men may be born with a congenital abnormality that prevents them from ejaculating. This may include conditions such as retrograde ejaculation, in which semen flows backwards into the bladder instead of being ejaculated through the penis. In some cases, psychological factors such as anxiety, depression, or a history of sexual abuse can contribute to primary anejaculation. Certain medications, such as antidepressants or antipsychotics, can also interfere with ejaculation and cause primary anejaculation.


Secondary anejaculation, on the other hand, develops later in life after a man has been able to ejaculate normally. Some common causes for secondary ejaculation can include specific medications, neurological disorders, prostate surgery or ageing. As with primary anejaculation, certain medications can interfere with ejaculation and cause secondary anejaculation. These may include blood pressure medications, antidepressants, and antipsychotics. Neurological disorders such as multiple sclerosis or spinal cord injuries can damage the nerves that control ejaculation and lead to secondary anejaculation. Some men may experience secondary anejaculation after undergoing prostate surgery, as the procedure can damage the nerves and muscles involved in ejaculation. As men age, the muscles and nerves involved in ejaculation may weaken, leading to secondary anejaculation, hence making age also a major causative factor for anejaculation.

Anejaculation Due To Lifestyle Factors

One possible cause of anejaculation is lifestyle factors. Excessive alcohol consumption, drug use, and tobacco use can lead to anejaculation. These substances can affect the nervous system and disrupt the normal functioning of the body, leading to an inability to ejaculate. For example, alcohol can cause nerve damage and interfere with hormonal regulation, which can contribute to anejaculation. Similarly, drug use and tobacco use can also damage nerves and interfere with hormone levels, leading to anejaculation. Reducing or eliminating these lifestyle factors may help to resolve anejaculation in some cases.

Is Anejaculation A Common Condition?

Anejaculation is a relatively uncommon condition that affects only a small percentage of men. Secondary anejaculation is more common than primary anejaculation and can develop later in life. Primary anejaculation is a rare condition. For instance, primary anejaculation caused by retrograde ejaculation, a congenital defect, that causes semen to flow backwards into the bladder instead of being ejaculated through the penis, is a rare occurrence. 

How Is Anejaculation diagnosed?

Anejaculation can be diagnosed through a combination of medical history, physical examination, and laboratory tests. A healthcare professional, such as a urologist or a sex therapist, can perform a comprehensive evaluation to determine the underlying cause of anejaculation.

They would most likely ask questions about the patient’s sexual history, including the frequency of sexual activity, any difficulties with sexual function, and any medications that the patient is taking. They may also ask about the patient’s medical history, including any conditions or surgeries that may be contributing to anejaculation. A physical examination may also be performed to assess the patient’s genital and pelvic area to check for any abnormalities in the testicles or prostate gland, and may also evaluate the patient’s reflexes and nerve function.


In some cases, laboratory tests may be ordered to help diagnose anejaculation. These tests may include a semen analysis, which can help determine if there is a problem with sperm production or transport. Blood tests may also be ordered to evaluate hormone levels or to check for any underlying medical conditions.

How Can You Differentiate Anejaculation From Other Ejaculatory Dysfunctions?

Anejaculation can be differentiated from other ejaculatory dysfunctions based on several factors, including the timing of onset, the presence or absence of ejaculation, and the underlying causes.


One of the main ways to differentiate anejaculation from other ejaculatory dysfunctions is based on the timing of onset. Primary anejaculation occurs when a man has never been able to ejaculate during sexual activity or masturbation, while secondary anejaculation occurs when a man has previously been able to ejaculate normally but experiences difficulty ejaculating later in life. In contrast, other ejaculatory dysfunctions, such as premature ejaculation or delayed ejaculation, typically occur during sexual activity and are not related to the timing of onset.


Another way to differentiate anejaculation from other ejaculatory dysfunctions is based on the presence or absence of ejaculation. In anejaculation, there is a complete absence of ejaculation, while in other ejaculatory dysfunctions, such as premature ejaculation or delayed ejaculation, there is an ejaculation but it occurs too quickly or too slowly.


Finally, the underlying causes of anejaculation can help differentiate it from other ejaculatory dysfunctions. Anejaculation can be caused by a variety of factors, including congenital abnormalities, psychological factors, medications, neurological disorders, and ageing. In contrast, other ejaculatory dysfunctions may be caused by factors such as anxiety, relationship issues, or hormonal imbalances.

Early diagnosis and appropriate treatment can often lead to successful outcomes, and there are various treatment options available depending on the underlying cause of anejaculation. Remember, seeking help is the first step towards addressing anejaculation and regaining control over your sexual health.
