Natural treatment for male Infertility (Azoospermia)

Azoospermia is characterized by the complete absence of spermatozoa, leading tomale infertility. The first step in evaluating male fertility involves a detailed questionnaire, a targeted physical examination, and semen analysis.

To diagnose azoospermia, the absence of spermatozoa must be confirmed in two separate semen analyses conducted three months apart, based on the pellet obtained after centrifugation. Centrifugation of the semen helps differentiate azoospermia, in which no spermatozoa are present, from cryptozoospermia, which is characterized by the presence of a few rare spermatozoa in the semen.

Azoospermia is asymptomatic

For men,azoospermia presents no symptoms. Trying to conceive for one year without success defines infertility. In 20% of infertility cases, the cause is male, and in 40%, it is mixed. Thus, in 60% of cases, the man is at least partially responsible for the infertility.

What are the different types of azoospermia (obstructive, secretory, excretory, etc.)?

Azoospermia can be obstructive (excretory) or non-obstructive (also called secretory) in origin.

Excretory azoospermia

In this type of obstructive azoospermia, testicular production occurs on both sides. However, there is a barrier between the testicle and the prostate, which may be located in the ejaculatory ducts, vas deferens, or epididymis. Clinically, the testicles are adequately sized, and the genital ducts are often dilated.

Secretory azoospermia

More common, the non-obstructive anomaly is also called secretory. In this specific case, the testicles fail to produce sperm. This dysfunction may indicate the absence of germ cells in the testicle. Typically, the testicle is reduced in size.

There are two types of secretory azoospermia: central secretory azoospermia, of hypothalamic-pituitary origin, and peripheral secretory azoospermia, of testicular origin.

What are the causes and risk factors for azoospermia?

The causes of azoospermia are multifactorial.

Genetic and infectious causes of excretory azoospermia In people with cystic fibrosis, or carriers of the mutated gene, the vas deferens, epididymides, and seminal vesicles are absent or poorly developed. Certain genital diseases such as chlamydia or gonococcus can affect the excretory tract.

Constitutional, genetic, and acquired causes of secretory azoospermia

The causes of secretory azoospermia are multiple. They may include constitutional abnormalities, genetic or non-genetic factors, as well as acquired causes.

Constitutional abnormalities:
This may involve a problem in testicular development during fetal life.

Genetic abnormalities of sex chromosomes:
Sex chromosome abnormalities represent the majority of chromosomal anomalies found in infertile men. The most common are men with Klinefelter syndrome (47,XXY) and Klinefelter mosaics (47,XXY/46,XY).

Y chromosome microdeletions:
Y chromosome microdeletions are another frequent genetic cause of male infertility. This cause is specifically linked tosecretory azoospermia.

Acquired causes:

A common acquired cause of secretory azoospermia is varicocele, which may be associated with testicular dysfunction, leading to reduced testicular volume and decreased sperm concentration in the ejaculate. Varicocele is found in about 40% of infertile men.

Chemotherapy or pelvic radiotherapy may also affect testicular function.

Secretory azoospermia may also be detected following orchiepididymitis, an infection of the testes and/or epididymis that can occur in the context of a sexually transmitted infection (STI). It can also be related to a history of cryptorchidism.

Possible symptoms of azoospermia

Infertility: Inability to conceive a child after 12 months of regular unprotected sexual intercourse. This is the main revealing sign.

Signs related to hormonal disorders (in cases of non-obstructive azoospermia):

 Low libido (decreased sexual desire), 

Chronic fatigue.

Erectile dysfunction.

Reduced facial or body hair.

Decreased muscle mass.

Gynecomastia (development of breast tissue in men).

Signs related to an obstructive cause (blockage of the ducts):

Low or absent ejaculate volume.

Pain or swelling in the scrotum.

History of genital infections, surgery, or testicular trauma.

Other possible clinical signs depending on the cause:

Small testicles (testicular hypotrophy).

History of genetic disorders (e.g., Klinefelter syndrome).

Testicular or groin pain (rare).

Diagnosis of azoospermia

During the first consultation aimed at guiding the diagnosis, an assessment is carried out that includes identifying the risk factors for male infertility. For a more detailed evaluation, when azoospermia is suspected, a physical examination is recommended, including the assessment of androgenization and inspection of the external genital organs (palpation of the testes, epididymis, etc.). The initial endocrine evaluation should include at least a measurement of total testosterone and FSH.

A semen analysis (spermogram) and the postcoital Hühner test represent two additional tests to diagnose azoospermia.

The diagnosis of azoospermia is made in several steps, since the absence of spermatozoa can have different causes (obstruction, hormonal problems, or testicular production defects).

Steps in the Diagnosis of Azoospermia

Medical history (anamnesis):
The doctor seeks to determine:

Medical history (infections, surgeries, genital trauma, exposure to toxins).

Family history of genetic disorders.

Sexual history (libido, erectile dysfunction).

Lifestyle habits (alcohol, tobacco, drugs, excessive heat, medications).

Physical examination:

Palpation of the testes (size, consistency, abnormalities).

Screening for varicocele (dilation of the scrotal veins).

Observation of hormonal signs: body hair, breast development (gynecomastia), muscle mass.

Semen analysis (key examination):

Performed after 2 to 5 days of sexual abstinence.

Confirms the total absence of spermatozoa.

The test should be repeated at least twice to confirm the diagnosis.

Additional tests:

Hormonal analysis: measurement of FSH, LH, testosterone, and prolactin (to determine if the problem is related to impaired hormone production).

Scrotal and transrectal ultrasound: detects obstruction of the vas deferens, prostate abnormalities, or seminal vesicle issues.

Genetic testing: screening for Y chromosome microdeletions, karyotype (e.g., Klinefelter syndrome), and genetic mutations (e.g., CFTR in cystic fibrosis).

Testicular biopsy (if necessary): determines whether the testes are producing spermatozoa or not.

Non-routine genetic tests:

Genetic testing is not systematically performed for all cases of azoospermia. It is usually indicated in the following situations:

Severe oligospermia or non-obstructive azoospermia.

History of genetic disorders in the family.

Suspected chromosomal abnormalities or congenital conditions.

Prior failed attempts at assisted reproductive techniques.

Common genetic evaluations include:

Karyotype analysis (e.g., Klinefelter syndrome).

Y chromosome microdeletion analysis.

CFTR gene mutation testing in cases of congenital absence of the vas deferens.

Treatments of Azoospermia

The treatment depends on the underlying cause:

 Obstructive azoospermia (blockage of the reproductive ducts):

Surgical reconstruction:

Vasovasostomy (reconnection of the vas deferens).

Epididymovasostomy (bypass of an epididymal obstruction).

Treatment of infections: antibiotics if obstruction is due to infection.

Sperm retrieval procedures:

PESA (Percutaneous Epididymal Sperm Aspiration).

TESA (Testicular Sperm Aspiration).

Retrieved sperm can be used for IVF with ICSI (intracytoplasmic sperm injection).

 Non-obstructive azoospermia (production problem):

Hormonal therapy if hormonal deficiency is present (e.g., gonadotropins such as hCG and FSH).

Correction of endocrine disorders (e.g., hyperprolactinemia treated with dopamine agonists, hypothyroidism treated with levothyroxine).

Varicocele repair (surgical ligation or embolization) to improve sperm production.

Testicular biopsy (TESE or micro-TESE) for sperm retrieval when production is very low, followed by ICSI.

 Irreversible or genetic causes:

Genetic counseling to assess transmission risks.

Sperm donation if no sperm can be obtained.

Adoption as an alternative.

Supportive natural and lifestyle approaches:

Balanced diet rich in zinc, selenium, vitamins C and E, and antioxidants.

Stress reduction.

Moderate, regular exercise.

Adequate sleep.

Avoiding excessive heat (hot baths, laptops on the lap).

Avoiding tobacco, alcohol, drugs, and toxic exposures

Complications of Azoospermia

The complications of azoospermia depend on its underlying cause (obstructive or non-obstructive) and the absence of treatment. The main complications include:

Male infertility:

The most direct complication: inability to conceive naturally.

Often, azoospermia is discovered during an infertility evaluation.

 Psychological and social complications:

Stress, anxiety, and depression related to infertility.

Feelings of loss of masculinity.

Strain on relationships and potential social isolation.

Hormonal complications (if testicular or pituitary cause):

Reduced libido.

Erectile dysfunction.

Chronic fatigue.

Reduced body hair, decreased muscle mass.

Gynecomastia (development of breast tissue in men).

Long-term risk of osteoporosis in case of prolonged testosterone deficiency.

Medical complications related to the underlying cause:

Untreated varicocele: may lead to testicular atrophy and persistent pain.

Chronic genital infections: pelvic pain, risk of recurrence.

Genetic causes (e.g., Klinefelter syndrome, Y chromosome anomalies): may be associated with metabolic or endocrine disorders.

Testicular tumors: sometimes discovered during azoospermia evaluation.

 Complications related to treatment procedures:

After testicular biopsy: risk of pain, infection, or hematoma.

After surgery (e.g., correction of obstruction): risk of recurrence or failure to restore fertility.

Preventive Measures Against Azoospermia

While azoospermia cannot always be prevented (especially if it is genetic or congenital), certain measures can reduce the risk when it is related to environmental, infectious, or hormonal factors.

 Prevention of genital infections:

Protect sexual intercourse (use condoms) to prevent STIs such as chlamydia or gonorrhea, which can cause duct obstruction.

Prompt treatment of urinary or genital infections.

 Protection of the testes:

Avoid trauma to the testes (use protective gear during contact sports).

Monitor and treat testicular trauma or torsion promptly.

 Healthy lifestyle habits:

Avoid tobacco, alcohol, and recreational drugs, which can impair spermatogenesis.

Limit exposure to excessive heat (hot baths, laptops on the lap).

Avoid prolonged exposure to chemicals and radiation (pesticides, solvents, heavy metals).

 Hormonal and metabolic prevention:

Avoid abuse of anabolic steroids, which suppress natural testosterone and sperm production.

Manage obesity, diabetes, and hormonal imbalances.

 Regular medical check-ups:

Seek an andrological evaluation in case of difficulty conceiving or history of infections, mumps, varicocele, or testicular tumors.

Consult a doctor early in case of hormonal symptoms (low libido, gynecomastia, small testes).

 Genetic prevention (if there is a family risk):

Genetic counseling before conception.

Early screening if there is a family history of genetic conditions affecting male fertility.
