What is azoospermia

 Azoospermia means there’s no sperm in a man’s ejaculate. Its causes include a blockage along the reproductive tract, hormonal problems, ejaculation problems, or issues with testicular structure or function. Many causes are treatable and fertility can be restored. For other cases, it may be possible to retrieve live sperm to be used in assisted reproductive techniques.

What is azoospermia?

Azoospermia is a condition in which there’s no measurable sperm in a man’s ejaculate (semen). Azoospermia leads to male infertility.

Are there different types of azoospermia?

There are two main types of azoospermia:

Obstructive azoospermia: This type of azoospermia means that there is a blockage or missing connection in the epididymis, vas deferens, or elsewhere along your reproductive tract. You are producing sperm but it’s getting blocked from the exit so there’s no measurable amount of sperm in your semen.

Nonobstructive azoospermia: This type of azoospermia means you have poor or no sperm production due to defects in the structure or function of the testicles or other causes.

What are the causes of azoospermia?

The causes of azoospermia relate directly to the types of azoospermia. In other words, causes can be due to an obstruction or nonobstructive sources.

Obstructions that result in azoospermia most commonly occur in the vas deferens, the epididymis, or ejaculatory ducts. Problems that can cause blockages in these areas to include:

  • Trauma or injury to these areas.
  • Infections.
  • Inflammation.
  • Previous surgeries in the pelvic area.
  • Development of a cyst.
  • Vasectomy (planned permanent contraceptive procedure in which the vas deferens are cut or clamped to prevent the flow of sperm).
  • Cystic fibrosis gene mutation, causes either the vas deferens not to form or causes abnormal development such that semen gets blocked by a buildup of thick secretions in the vas deferens.

Nonobstructive causes of azoospermia include:

  • Genetic causes. Certain genetic mutations can result in infertility, including:
    • Kallmann syndrome: A genetic (inherited) disorder carried on the X chromosome that if left untreated can result in infertility.
    • Klinefelter’s syndrome: A male carries an extra X chromosome (making his chromosomal makeup XXY instead of XY). The result is often infertility, along with a lack of sexual or physical maturity, and learning difficulties.
    • Y chromosome deletion: Critical sections of genes on the Y chromosome (the male chromosome) that are responsible for sperm production are missing, resulting in infertility.
  • Hormone imbalances/endocrine disorders, including hypogonadotropic hypogonadism. hyperprolactinemia and androgen resistance.
  • Ejaculation problems such as retrograde ejaculation where the semen goes into the bladder
  • Testicular causes include:
    • Anorchia (absence of the testicles).
    • Cryptorchidism (testicles have not dropped into the scrotum).
    • Sertoli cell-only syndrome (testicles fail to produce living sperm cells).
    • Spermatogenic arrest (testicles fail to produce fully mature sperm cells).
    • Mumps orchitis (inflamed testicles caused by mumps in late puberty).
    • Testicular torsion.
    • Tumors.
    • Reactions to certain medications that harm sperm production.
    • Radiation treatments.
    • Diseases such as diabetes, cirrhosis, or kidney failure.
    • Varicocele (veins coming from the testicle are dilated or widened impeding sperm production).

How is azoospermia diagnosed?

Azoospermia is diagnosed when, on two separate occasions, your sperm sample reveals no sperm when examined under a high-powered microscope following a spin in a centrifuge. A centrifuge is a laboratory instrument that spins a test sample at a high speed to separate it into its various parts. In the case of centrifuged seminal fluid, if sperm cells are present, they separate from the fluid around them and can be viewed under a microscope.

As part of the diagnosis, your healthcare provider will take your medical history, including asking you about the following:

  • Fertility success or failure in the past (your ability to have children).
  • Childhood illnesses.
  • Injuries or surgeries in the pelvic area (these could cause duct blockage or poor blood supply to the testicles).
  • Urinary or reproductive tract infections.
  • History of sexually transmitted diseases.
  • Exposure to radiation or chemotherapy.
  • Your current and past medications.
  • Any abuse of alcohol, marijuana, or other drugs.
  • Recent fevers or exposure to heat, including frequent saunas or steam baths (heat kills sperm cells).
  • Family history of birth defects, learning disabilities, reproductive failure, or cystic fibrosis.

Your healthcare provider will also conduct a physical examination, and will check:

  • Your entire body in terms of signs of/lack of maturation of your body and reproductive organs.
  • Your penis and scrotum, checking for the presence of your vas deferens, tenderness or swelling of your epididymis, size of the testicles, the presence or absence of a varicocele, and any blockage of the ejaculatory duct (via exam through the rectum) as evidenced by enlarged seminal vesicles.
  • Your healthcare provider may also order the following tests:
  • Measurement of testosterone and follicle-stimulating hormone (FSH) levels.
  • Genetic testing.
  • X-rays or ultrasound of the reproductive organs to see if there are any problems with the shape and size, and to see if there are tumors, blockages, or an inadequate blood supply.
  • Imaging of the brain to identify disorders of the hypothalamus or pituitary gland.
  • Biopsy (tissue sampling) of the testes. A normal biopsy would mean a blockage is probable at some point in the sperm transport system. Sometimes, any sperm found in the testes is frozen for future analysis or can be used in assisted pregnancy.

How is azoospermia treated?

Treatment of azoospermia depends on the cause. Genetic testing and counseling are often an important part of understanding and treating azoospermia. Treatment approaches include:

  • If a blockage is the cause of your azoospermia, surgery can unblock tubes or reconstruct and connect abnormal or never developed tubes.
  • If low hormone production is the main cause, you may be given hormone treatments. Hormones include follicle-stimulating hormone (FSH), human chorionic gonadotropin (HCG), clomiphene, anastrozole, and letrozole.
  • If a varicocele is the cause of poor sperm production, the problem veins can be tied off in a surgical procedure, keeping surrounding structures preserved.
  • Sperm can be retrieved directly from the testicle with an extensive biopsy in some men
  • If living sperm are present, they can be retrieved from the testes, epididymis, or vas deferens for assisted pregnancy procedures such as in vitro fertilization or intracytoplasmic sperm injection (the injection of one sperm into one egg). If the cause of azoospermia is thought to be something that could be passed on to children, your healthcare provider may recommend genetic analysis of your sperm before assisted fertilization procedures are considered.
