What Are the Types of Azoospermia?

Exploring the Main Types of Azoospermia

Before getting into what causes azoospermia in males, you need to know that the condition is classified into multiple types, depending on where the problem lies.

Broadly speaking, there are two types of azoospermia: Obstructive and Non-obstructive.

Obstructive Azoospermia:

This is the most common type of azoospermia, and it is caused by a blockage in a man’s reproductive tract. In such cases, the testes are producing sperm normally, but due to an obstruction in the tract, they are unable to exit and mix into the semen. Obstructive azoospermia could also mean that a person has a missing connection in the reproductive tract. It is also known as post-testicular azoospermia.

Non-obstructive azoospermia:

As the name suggests, this type of azoospermia is not caused by a blockage or obstruction in the pathway.

Non-obstructive azoospermia is also of two types: Testicular and Pre-testicular.

• Testicular Azoospermia: If diagnosed with testicular azoospermia, it would mean that you have poor or no sperm production. This could be due to a disorder or any kind of damage to the testicles.
• Pre-testicular Azoospermia: This happens when there isn’t enough stimulation by hormones to produce sperm in the first place. Your testicles and the reproductive tract may look normal in such cases. Hormonal imbalance and treatments like chemotherapy usually cause pre-testicular azoospermia.

Symptoms of Azoospermia and What Causes Obstructive Azoospermia

In most cases, there are no specific symptoms that may point to azoospermia. You may not know for sure until you are trying to get your partner pregnant. However, you should be on the lookout for the following signals:

• Semen quality and quantity: Here, your semen could either be thinner than normal, or you could be ejaculating in less quantity than usual.
• Erectile dysfunction: Some men affected by azoospermia may have trouble getting or keeping their penis erect during sexual intercourse.
• Low sex drive: You could experience a drop in your libido due to hormonal imbalances.
• Infertility: This is the biggest red flag when it comes to azoospermia, especially if you and your partner have been having regular unprotected sex.

Some causes of obstructive or post-testicular azoospermia include:

• Infections: Infections like epididymitis and Mumps orchitis can cause significant damage to the testicles. This causes trouble in normal sperm production.
• Trauma or injury to the testicles: This may cause a blockage, preventing the flow of semen despite normal production.
• Retrograde ejaculation: This happens when the semen is pushed backwards toward the bladder instead of the opening on the penis.
• Cystic fibrosis gene mutation: Here, your vas deferens may experience a buildup of thick secretions, which block the sperm. In some cases, the vas deferens may not be formed at all.
• Others: Inflammation, previous surgeries or cysts/growths may be causing obstructive azoospermia in some men. On the other hand, a vasectomy could also be a simple explanation as to why sperm are absent from the semen despite normal production.

Causes of Non-Obstructive Azoospermia

The causes of pre-testicular and testicular azoospermia could be genetic, hormonal, or something else entirely. As the name suggests, there is nothing causing any kind of blockage in the male reproductive tract.

Some common causes of non-obstructive azoospermia include:

• Genetics: Kallmann syndrome or the Y chromosome microdeletions are some of the few genetic conditions that may cause non-obstructive azoospermia in some men,
• Varicocele: Varicoceles are known as the swollen veins found in the man’s scrotum, and are usually a common cause of infertility.
• Hormonal imbalance: Endocrine disorders, such as low testosterone levels, can also hinder the production of sperm.
• Medications: Certain medications may also hinder normal sperm production.
• Treatments: Regular exposure to radiation treatments, chemotherapy, or heavy metals and toxins may lead to the development of non-obstructive azoospermia.
• Orchitis: Commonly caused by mumps, STDs, or urinary tract infections, orchitis is described as swelling and/or pain in either one or both of your testicles.
• Lifestyle choices: Apart from the above-mentioned causes, lifestyle decisions like drugs and alcohol abuse or spending long periods of time in hot places, such as hot tubs, could affect sperm production.

What Is Idiopathic Azoospermia?

While this is also a type of azoospermia, there is no known cause of the condition. Risk factors in such cases could include age and weight. Here, a man’s ejaculate may be devoid of sperm, all while there is no identifiable cause. Genes could also play a part here.

Since there is no telling what causes idiopathic azoospermia, it is difficult to talk about its diagnosis and treatment. That being said, a person may still be able to have biological children through means of sperm retrieval.

When Should You See a Doctor?

The absence of sperm in your ejaculate does not usually come with a long list of symptoms that cannot be ignored. However, if you have been trying to impregnate your partner for months or even a year, it may be time to pay your doctor a visit.

By doing so, you will increase the chances of starting a family through treatment or alternative options that your doctor may suggest. You must keep in mind that azoospermia is not something to be embarrassed about, and help is only a call away.

How Do Doctors Diagnose Azoospermia?

The most common and accurate way to diagnose azoospermia, either obstructive or non-obstructive, is by a physical exam and a thorough semen analysis. If your semen sample shows no sperm on two separate occasions, your doctor may diagnose you with azoospermia.

In order to figure out the root cause, they may ask you about your previous fertility, surgeries, infections, medication history, lifestyle, family history, and whether or not you have sustained any injuries to your pelvic region.

Other tests include:

• X-rays or ultrasound of the scrotum.
• Brain MRI if doctors have a reason to believe the hypothalamus or pituitary gland could be the culprit.
• Genetic testing.
• Blood test to measure testosterone and FSH.
• Diagnostic testicular biopsy.

Treatment Options for Different Types of Azoospermia

Azoospermia can be treated in many cases, but it all comes down to the cause. Medical professionals may treat the condition by:

• Surgery: Surgery can be done to unblock the tubes and ducts or connect and reconstruct the ones that are causing the problem. It is important to note that such surgeries will only work when there is a blockage or obstruction in the male reproductive tract which is not allowing the sperm to pass through normally.
• Hormones: In case of hormonal imbalances in the body affecting normal sperm production, you may be advised to take prescription hormone treatments so that the cause can be eradicated from the root.

Can Men with Azoospermia Become Biological Fathers?

If the treatment options do not work for you, there is no need to be disappointed. Over the last few years, medical science has come a long, long way, and there is still hope for you to have a biological child despite the absence of sperm in your semen. How Through sperm retrieval methods.

Here, doctors will retrieve the sperm directly from your testicles using a needle. The retrieved sperm is then used in assisted reproductive techniques. These techniques include in vitro fertilisation (IVF) or intracytoplasmic sperm injection (ICSI). By doing so, doctors can fulfil the man's dream of having kids of his own.

Conclusion

There are multiple types of azoospermia, including obstructive (post-testicular) and non-obstructive (testicular and pre-testicular). It is important to understand the types of azoospermia so that you can treat them accordingly and make a real difference in your sexual and reproductive life.

Be it obstructive or non-obstructive, azoospermia can be diagnosed through semen analysis, hormone evaluation, and imaging. After the diagnosis, there are multiple methods of treating the condition, depending on the cause and type of azoospermia. Lastly, advances in fertility treatments now allow men with the condition to pursue biological parenthood, even if they lose all hope.

There is nothing to be ashamed or embarrassed about an azoospermia diagnosis. Do not think twice before reaching out to a doctor, as this could change your life for the better.
