Male infertility

Mayoclinic
Male infertility

Approximately 15 percent of couples are infertile. This means they aren't able to conceive a child even though they've had frequent, unprotected sexual intercourse for a year or longer. In about half of these couples, male infertility plays a role.

Male infertility is due to low sperm production, abnormal sperm function or blockages that prevent the delivery of sperm. Illnesses, injuries, chronic health problems, lifestyle choices and other factors can play a role in causing male infertility.

Not being able to conceive a child can be stressful and frustrating, but a number of male infertility treatments are available.

Symptoms

The main sign of male infertility is the inability to conceive a child. There may be no other obvious signs or symptoms. In some cases, however, an underlying problem such as an inherited disorder, hormonal imbalance, dilated veins around the testicle, or a condition that blocks the passage of sperm may cause signs and symptoms. Male infertility signs and symptoms may include:

The inability to conceive a child

Problems with sexual function — for example, difficulty with ejaculation, reduced sexual desire or difficulty maintaining an erection (erectile dysfunction)

Pain, swelling or a lump in the testicle area

Recurrent respiratory infections

Decreased facial or body hair or other signs of a chromosomal or hormonal abnormality

Having a lower than normal sperm count (fewer than 15 million sperm per milliliter of semen or a total sperm count of less than 39 million per ejaculate)

Causes

Male fertility is a complex process. To get your partner pregnant, the following must occur:

You must produce healthy sperm. Initially, this involves the growth and formation of the male reproductive organs during puberty. At least one of your testicles must be functioning correctly, and your body must produce testosterone and other hormones to trigger and maintain sperm production.

Sperm have to be carried into the semen. Once sperm are produced in the testicles, delicate tubes transport them until they mix with semen and are ejaculated out of the penis.

There needs to be enough sperm in the semen. If the number of sperm in your semen (sperm count) is low, it decreases the odds that one of your sperm will fertilize your partner's egg. A low sperm count is fewer than 15 million sperm per milliliter of semen or fewer than 39 million per

ejaculate.

Sperm must be functional and able to move. If the movement (motility) or function of your sperm is abnormal, the sperm may not be able to reach or penetrate your partner's egg.

Medical causes

Problems with male fertility can be caused by a number of health issues and medical treatments. Some of these include:

Varicocele. A varicocele is a swelling of the veins that drain the testicle. It's the most common reversible cause of male infertility. This may prevent normal cooling of the testicle, leading to reduced sperm count and fewer moving sperm. Treating the varicocele can improve sperm numbers and function, and may potentially improve outcomes when using assisted reproductive techniques such as in vitro fertilization.

Infection. Some infections can interfere with sperm production or sperm health, or can cause scarring that blocks the passage of sperm. These include some sexually transmitted infections, including chlamydia and gonorrhea; inflammation of the prostate (prostatitis); and inflamed testicles due to mumps (mumps orchitis). Although some infections can result in permanent testicular damage, most often sperm can still be retrieved.

Ejaculation issues. Retrograde ejaculation occurs when semen enters the bladder during orgasm instead of emerging out the tip of the penis. Various health conditions can cause retrograde ejaculation, including diabetes, spinal injuries, medications, and surgery of the bladder, prostate or urethra. Some men with spinal cord injuries or certain diseases can't ejaculate semen, even though they still produce sperm. Often in these cases sperm can still be retrieved for use in assisted reproductive techniques. Antibodies that attack sperm. Anti-sperm antibodies are immune system cells that mistakenly identify sperm as harmful invaders and attempt to eliminate them.

Tumors. Cancers and nonmalignant tumors can affect the male reproductive organs directly or can affect the glands that release hormones related to reproduction, such as the pituitary gland. In some cases, surgery, radiation or chemotherapy to treat tumors can affect male fertility.

Undescended testicles. In some males, during fetal development one or both testicles fail to descend from the abdomen into the sac that normally contains the testicles (scrotum). Decreased fertility is more likely in men who have had this condition.

Hormone imbalances. Infertility can result from disorders of the testicles themselves or an abnormality affecting other hormonal systems including the hypothalamus, pituitary, thyroid and adrenal glands. Low testosterone (male hypogonadism) and other hormonal problems have a number of possible underlying causes.

Sperm duct defects. The tubes that carry sperm (sperm ducts) can be damaged by illness or injury. Some men experience blockage in the part of the testicle that stores sperm (epididymis) or a blockage of one or both of the tubes that carry sperm out of the testicles. Men with cystic fibrosis and some other inherited conditions may be born without sperm ducts  altogether.

Chromosome defects. Inherited disorders such as Klinefelter's syndrome — in which a male is born with two X chromosomes and one Y chromosome (instead of one X and one Y) — cause abnormal development of the male reproductive organs. Other genetic syndromes associated with infertility include cystic fibrosis, Kallmann's syndrome and Kartagener syndrome.

Problems with sexual intercourse. These can include trouble keeping or maintaining an erection sufficient for sex (erectile dysfunction), premature ejaculation, painful intercourse, anatomical abnormalities such as having a urethral opening beneath the penis (hypospadias), or psychological or relationship problems that interfere with sex.

Celiac disease. A digestive disorder caused by sensitivity to gluten, celiac disease can cause male infertility. Fertility may improve after adopting a gluten-free diet.

Certain medications. Testosterone replacement therapy, long-term anabolic steroid use, cancer medications (chemotherapy), certain antifungal medications, some ulcer drugs and certain other medications can impair sperm production and decrease male fertility.

Prior surgeries. Certain surgeries may prevent you from having sperm in your ejaculate, including vasectomy, inguinal hernia repairs, scrotal or testicular surgeries, prostate surgeries, and large abdominal surgeries performed for testicular and rectal cancers, among others. In most cases, surgery can be performed to either reverse these blockage or to retrieve sperm directly from the epididymis and testicles.

Risk factors

A number of risk factors are linked to male infertility. They include:

Smoking tobacco

Using alcohol

Using certain illegal drugs

Being overweight

Having certain past or present infections

Being exposed to toxins

Overheating the testicles

Having a prior vasectomy or major abdominal or pelvic surgery

Being born with a fertility disorder or having a blood relative with a fertility disorder

Having certain medical conditions, including tumors and chronic illnesses

Taking certain medications or undergoing medical treatments, such surgery or radiation used for treating cancer

Performing certain prolonged activities such as bicycling

or horseback riding, especially on a hard seat or poorly adjusted

bicycle

Tests and diagnosis

Many infertile couples have more than one cause of infertility, so it's likely you will both need to see a doctor. It may take a number of tests to determine the cause of infertility. In some cases, a cause is never identified. Infertility tests can be expensive and may not be covered by insurance — find out what your medical plan covers ahead of time.

Diagnosing male infertility problems usually involves:

General physical examination and medical history. This includes examining your genitals and questions about any inherited conditions, chronic health problems, illnesses, injuries or surgeries that could affect fertility. Your doctor may also ask about your sexual habits and about your sexual development during puberty.

Semen analysis. Semen is generally obtained by masturbating and ejaculating into a special container at the doctor's office. Your semen is then sent to a laboratory to measure the number of sperm present and look for any abnormalities in the shape (morphology) and movement (motility) of the sperm. The lab will also check your semen for signs of problems such as infections. Often sperm counts fluctuate from one specimen to the next. In most cases, several semen analysis tests are done over a period of time to ensure accurate results. If your sperm analysis is normal, your doctor will likely recommend thorough testing of your female partner before conducting any more male infertility tests.

Your doctor may recommend additional tests to help identify the cause of your infertility. These can include:

Scrotal ultrasound. This test uses high-frequency sound waves to produce images inside your body. A scrotal ultrasound can help your doctor see obstructions or other problems in the testicles and supporting structures.

Transrectal ultrasound. A small, lubricated wand is inserted into your rectum. It allows your doctor to check your prostate, and look for blockages of the tubes that carry semen (ejaculatory ducts and seminal vesicles).

Hormone testing. Hormones produced by the pituitary, hypothalamus and testicles play a key role in sexual development and sperm production. Abnormalities in other hormonal or organ systems may also contribute to infertility. A blood test measures the level of testosterone and other hormones.

Post-ejaculation urinalysis. Sperm in your urine can indicate your sperm are traveling backward into the bladder instead of out your penis during ejaculation (retrograde ejaculation).

Genetic tests.  When sperm concentration is extremely low, genetic causes could be involved. A blood test can reveal whether there are subtle changes in the Y chromosome — signs of a genetic abnormality. Genetic testing may also be ordered to diagnose various congenital or inherited syndromes.

Testicular biopsy. This test involves removing samples from the testicle with a needle. The results of the testicular biopsy will tell if sperm production is normal. If it is, your problem is likely caused by a blockage or another problem with sperm transport.

Other testing. In some cases, other blood or semen tests may be recommended to try to determine why the sperm may not be able to effectively fertilize the egg.

Specialized sperm function tests. A number of tests can be used to check how well your sperm survive after ejaculation, how well they can penetrate an egg, and whether there's any problem attaching to the egg. If you do have a low sperm count, having healthy sperm can be an important factor in male fertility.

Treatments and drugs

Your doctor will try to improve your fertility by either correcting an underlying problem (if one is found) or trying treatments that seem like they may be helpful. Often, an exact cause of infertility can't be identified. Even if an exact cause isn't clear, your doctor may be able to recommend treatments that work. In many cases of infertility, the female partner also will need to be checked and may need treatment.

Treatments for male infertility include:

Surgery. For example, a varicocele can often be surgically corrected or an obstructed vas deferens repaired. Vasectomy can often be reversed. In cases where no sperm are present in the ejaculate, sperm may often be retrieved directly from the testicles or epididymis using sperm retrieval techniques.

Treating infections. Antibiotic treatment may cure an infection of the reproductive tract, but doesn't always restore fertility.

Treatments for sexual intercourse problems. Medication or counseling can help improve fertility in conditions such as erectile dysfunction or premature ejaculation.

Hormone treatments and medications. Your doctor may recommend hormone replacement or medications in cases where infertility is caused by high or low levels of certain hormones or problems with the way the body uses hormones.

Assisted reproductive technology (ART). ART treatments involve obtaining sperm through normal ejaculation, surgical extraction or from donor individuals, depending on your specific case and wishes. The sperm is then inserted into the female genital tract, or used to perform in vitro fertilization or intracytoplasmic sperm injection.
