It’s definitely a big shock for men when their semen report shows zero sperm. Many feel confused and overwhelmed. Azoospermia is a rare condition found in 1 in 100 men and in about 10-15 men in 100 who are facing infertility. But that does not mean it’s a sign of weakness; it is a medical condition for which there are treatments.
The interesting fact is that many men with azoospermia can still become biological fathers with the right tests and guided treatment plans. Explore the causes, tests, and treatment options for azoospermia.
What Is Azoospermia?
Azoospermia is a condition in which there is no sperm in the ejaculated semen. It is confirmed through semen analysis, where the semen sample is spun in a centrifuge and checked under a microscope, so that even a few sperm are not missed.
Many people also confuse azoospermia with aspermia, a condition where no semen comes out at all during ejaculation.
What Are the Types of Azoospermia?
Azoospermia is generally divided into two main types: obstructive and non-obstructive. Knowing which one you have helps doctors to decide which tests and treatments you need and which are appropriate:
- Obstructive azoospermia
In obstructive azoospermia, testicles make sperm, but a blockage stops the sperm from reaching the semen. It could possibly be due to blockages in the epididymis or vas deferens, due to previous infections or inflammations that have destroyed the reproductive tract, due to past surgeries or injuries that have affected the sperm pathway, or even due to certain conditions that are present from birth. - Non-obstructive azoospermia
In non-obstructive azoospermia, the testicles are either not making enough sperm, or no sperm is found at all. This is due to hormonal imbalances affecting sperm production, genetic conditions, testicular damage, any medical treatments in the past, or the presence of conditions that affect the development or function of the testicles.
In some cases, small areas of the testicles may still produce sperm even when no sperm is found in the semen. A fertility specialist may assess whether surgical sperm retrieval is an option.
What Causes Azoospermia?
There are several underlying factors that contribute to azoospermia, such as:
- A previous vasectomy (the most common cause of a blocked sperm tube)
- Missing sperm tubes (vas deferens) from birth. This is often linked to changes in the CFTR gene and is found in about 1 in 100 infertile men
- Serious infections of the genital tract
- Injury or surgery in the groin or scrotum
- Blockage in the ejaculatory ducts
- Genetic problems, such as Klinefelter syndrome (an extra X chromosome) or missing parts of the Y chromosome
- Hormone problems, such as low FSH and LH, or high prolactin
- Undescended testicles
- Mumps infection that affected the testicles
- Chemotherapy or radiation
- Testosterone injections, anabolic steroids, and some other medicines
- Varicocele (enlarged veins in the scrotum), in some men
What are the Symptoms of Azoospermia?
There are no obvious signs shown by men with azoospermia because it is only discovered when they go for fertility testing. Yet the first sign can usually be that a couple is not able to conceive. Some men may notice:
- Small or soft testicles
- Low libido or erection problems
- Less facial or body hair
- Pain or swelling in the scrotum
- Breast enlargement
Note that having these symptoms does not mean a man has azoospermia. Only the semen analysis will determine it.
How Is Azoospermia Diagnosed?
Finding the cause of azoospermia is an important step towards choosing the right treatment. First, it is confirmed using the two semen samples and the doctor evaluating your medical history, testicles, and sperm tubes. Then, based on the results, treatment is recommended, which could be:
- Hormone tests
The blood test measures testosterone and FSH. A high FSH with small testicles usually points to non-obstructive azoospermia. Prolactin is checked if the hormone levels suggest a pituitary problem. - Post-ejaculation urine test
It is required to rule out retrograde ejaculation, mainly when the semen volume is low. - Scrotal or other ultrasound
Ultrasounds or other investigations are recommended to check the testicles and the sperm tubes to get useful information. - Genetic tests
Karyotype, Y chromosome microdeletion test, and CFTR gene tests are advised depending on the suspected cause to identify conditions linked to impaired sperm production or abnormalities in the reproductive tract. - Testicular biopsy
It is required only in selected men, for example when the testicles are normal in size and FSH is normal, to tell if sperm are being made.
Once the results are available, the doctor can explain the likely cause, whether the condition may be treatable, and which fertility options are worth considering.
Treatment options for Azoospermia
Every case of azoospermia requires a different approach and treatment plan. It depends on whether the problem involves sperm production, sperm transport, hormones, or another underlying condition. The ways azoospermia is treated are as follows:
- Treating hormonal problems:
If a specific hormonal condition is responsible, then with appropriate medication, the hormonal function can be restored. - Surgery to correct blockages:
Surgery is considered for some men with obstructive azoospermia to repair the blockage and restore the passage of sperm. Whether the surgery option is suitable depends on the location of the blockage and other clinical factors. - Surgical sperm retrieval:
If surgery is not suitable or sperm is not present in the semen, then it is directly collected from the epididymis or testicles. In obstructive azoospermia, the micro-TESE procedure is used, which uses a surgical microscope to help identify areas of the testicular tissue that may contain sperm. - IVF with ICSI:
Once the suitable sperm are retrieved, IVF with ICSI is another option. Eggs are collected from the female partner, and sperm is injected directly into an egg in the laboratory. An embryo is then transferred to the uterus.
What If No Sperm Is Found?
This can happen in some men with non-obstructive azoospermia, and the chance of success is usually lower. But you still have options to explore, like donor sperm or adoption. This is a very personal discussion that should be made after understanding every possible treatment.
Your doctor can talk through each option with you and your partner so you can decide at your own pace.
Tips to support your sperm health
Lifestyle changes will not automatically cure azoospermia, but healthy habits support your overall reproductive health. Men planning to become fathers can take precautions and can inculcate habits like:
- Not using anabolic steroids or testosterone supplements without a doctor’s prescription.
- Avoid smoking, alcohol, and recreational drug use.
- Keep a healthy weight.
- Do not take unprescribed fertility boosters.
- Maintain a balanced diet and regular physical activity.
- Avoid wearing tight and synthetic underwears , as it affects the temperature to which the sperms are exposed .
- Seek medical advice for known hormonal or reproductive health concerns.
