Male Infertility/Azoospermia
What is Male Infertility/Azoospermia?
Male infertility affects about 7% of all men. It means a man has difficulty causing pregnancy with a female partner. Azoospermia is one specific cause of male infertility. It means there is no measurable sperm in the semen.
Azoospermia occurs in about 1% of all men and 15% of infertile men. There are two main types. Obstructive azoospermia means sperm is produced but blocked from leaving the body. Non-obstructive azoospermia means the testicles are not producing sperm at all. Understanding which type you have changes your treatment options.
Blood tests can help identify the root cause of azoospermia. Follicle-stimulating hormone, or FSH, is a key marker. High FSH levels suggest the testicles are not responding properly. Low FSH levels suggest the brain is not sending the right signals. This distinction helps your doctor create a targeted treatment plan.
Symptoms
- Inability to conceive after 12 months of unprotected intercourse
- Low semen volume during ejaculation
- Swelling or pain in the testicle area
- Decreased facial or body hair
- Inability to smell, which may signal hormonal issues
- Breast tissue growth or gynecomastia
- Low sex drive or erectile dysfunction
Many men with azoospermia have no obvious symptoms. Sexual function and ejaculation may feel completely normal. The only sign may be difficulty conceiving a child. This is why fertility testing is important for couples trying to get pregnant.

Causes and risk factors
Azoospermia has many possible causes. Obstructive causes include previous infections, surgeries, or injuries that block sperm transport. Vasectomy is an intentional form of obstruction. Genetic conditions like cystic fibrosis can cause missing vas deferens tubes. Non-obstructive causes include genetic disorders like Klinefelter syndrome, hormonal imbalances, varicocele, undescended testicles, or previous chemotherapy or radiation.
Lifestyle factors can affect sperm production. Heavy alcohol use, smoking, marijuana use, and anabolic steroid use all harm fertility. Environmental toxins and heat exposure may reduce sperm count. Obesity and poorly controlled diabetes also increase risk. Some medications, including certain blood pressure drugs and antidepressants, can affect sperm production. Age plays a role too, with sperm quality declining gradually after age 40.
How it's diagnosed
Diagnosis starts with a semen analysis. A lab examines semen under a microscope to count sperm. If no sperm are found in two separate samples, azoospermia is confirmed. Your doctor will then perform a physical exam and review your medical history.
Blood tests help identify the underlying cause. Follicle-stimulating hormone or FSH is especially important. High FSH with azoospermia suggests primary testicular failure or damaged sperm-producing cells. Low FSH may indicate the pituitary gland or hypothalamus is not working properly. Rite Aid offers FSH testing at Quest Diagnostics locations nationwide. Additional tests may include testosterone, luteinizing hormone, genetic testing, or testicular ultrasound.
Treatment options
- Hormone therapy for men with low FSH and pituitary issues
- Surgery to repair blockages in obstructive azoospermia
- Varicocele repair to improve testicular function
- Stopping medications or substances that harm sperm production
- Weight loss and exercise to improve hormonal balance
- Testicular sperm extraction or TESE for assisted reproduction
- Donor sperm or adoption for couples unable to conceive naturally
- Treatment of underlying conditions like diabetes or thyroid disorders

Frequently asked questions
Male infertility is a broad term for any difficulty causing pregnancy. Azoospermia is one specific cause of male infertility. It means there is zero sperm in the semen. Not all infertile men have azoospermia, but all men with azoospermia are infertile without treatment.
Some types of azoospermia can be reversed. Men with obstructive azoospermia may benefit from surgery to clear blockages. Men with hormonal issues may respond to hormone therapy. Non-obstructive azoospermia due to testicular failure is harder to treat, but sperm extraction techniques may still allow fatherhood.
FSH is a hormone that tells the testicles to make sperm. High FSH means the brain is trying hard but the testicles are not responding. This suggests primary testicular failure. Low FSH means the brain is not sending proper signals. This distinction guides treatment decisions.
Normal FSH levels for adult men typically range from 1.5 to 12.4 mIU/mL. Levels above this range with azoospermia suggest testicular failure. Levels below this range may indicate pituitary or hypothalamic problems. Your doctor will interpret your results based on your complete clinical picture.
Not always. Azoospermia caused by blockages, hormonal imbalances, or medication side effects may be reversible. Azoospermia from genetic conditions or testicular damage is usually permanent. Even in permanent cases, surgical sperm retrieval may find viable sperm for assisted reproduction.
Lifestyle changes help in some cases. Stopping anabolic steroids, reducing alcohol, quitting smoking, and losing weight can improve hormone levels. These changes work best when azoospermia is caused by reversible factors. Genetic or structural causes require medical intervention beyond lifestyle alone.
The full sperm production cycle takes about 74 days. After starting treatment for reversible causes, you may need to wait 3 to 6 months to see improvement. Your doctor will retest your semen after this period. Patience is important during the treatment process.
Yes, in many cases. Men with obstructive azoospermia often have sperm that can be surgically retrieved. Even some men with non-obstructive azoospermia have small pockets of sperm in the testicles. These sperm can be used with in vitro fertilization or IVF to achieve pregnancy.
Testosterone and luteinizing hormone or LH are also important. Low testosterone may indicate hormonal problems affecting fertility. Prolactin should be checked because high levels can suppress sperm production. Your doctor may order a hormone panel to see the complete picture.
Couples under 35 should see a specialist after 12 months of trying to conceive. Couples over 35 should seek help after 6 months. If a man has known risk factors like undescended testicles, prior surgery, or very low semen volume, earlier evaluation is appropriate.
