“Infertility is much more common than many people think. One in approximately eight couples experience infertility, and half of all couples experiencing infertility have a contributing male factor. For most men with infertility, we can make a diagnosis and provide multiple avenues for treatment. I am passionate about helping couples build and grow their families. I value communication and strong relationships with my patients. It would be my privilege to meet with you and discuss your goals.” – Matt Coward, MD

Infertility Tests

Your fertility specialist may use some of the following tests and procedures to accurately diagnose the specific structural or medical issues that may be causing infertility:

• Scrotal ultrasound. This test uses high-frequency sound waves to capture images of the inside of your testicles and other anatomy. A scrotal ultrasound can reveal if there is a varicocele or other problems in the testicles and supporting structures.
• Transrectal ultrasound. A small, lubricated wand is inserted into your rectum to allow the specialist to examine your prostate and look for blockages of the tubes that carry semen.
• Post-ejaculation urinalysis. If your urine contains sperm, it may indicate that the sperm are traveling backward into the bladder instead of out through the penis during ejaculation (this is called retrograde ejaculation).
• Advanced semen tests. A test called DNA fragmentation may be recommended to evaluate the DNA quality of the sperm.
• Genetic tests. When sperm concentration in semen is extremely low, there might be a genetic cause. Blood tests can uncover whether there are an abnormal number of chromosomes, mismatched material from one chromosome to another, or subtle changes in the male Y chromosome, which are signs of a genetic abnormality. Genetic testing can be ordered to diagnose various congenital or inherited conditions.
• Hormone testing. Hormones produced by the pituitary gland and the testicles play a key role in sexual development and the production of sperm. Abnormalities in other hormonal or organ systems can also contribute to infertility. A blood test can measure the level of hormones and testosterone.
• Testicular biopsy. This procedure involves removing samples from the testicle to determine if sperm production is normal and whether the fertility problem is caused by a blockage or another problem with the ability of sperm to move and transport themselves effectively.

What Factors Determine the Health of Sperm?

Sperm health is evaluated on a variety of factors, including quantity, movement, and structure:

• Quantity. Quantity refers to the number of sperm in a male’s ejaculate–the semen discharged in a single ejaculate. A male is most likely to be fertile if his semen contains at least 15 million sperm per milliliter. Too little sperm in an ejaculate can make it more difficult to get pregnant because there are fewer sperm available to make the journey to an egg and succeed in fertilization.
• Movement (motility). In order to reach and fertilize an egg, sperm must move and swim through a woman’s cervix and up into the uterus and fallopian tubes. This movement is known as motility. A male is most likely to be fertile if at least 40% of sperm are able to move.
• Structure (morphology). Normal sperm have long tails and oval heads. This structural design works to propel them. While structure is not as important a factor as sperm quantity or movement, the more sperm a male has with a normal shape and structure, the more likely a male is to be fertile.

A fertility specialist will count the number of sperm in a sample, analyze its structure, and watch its movement.  The laboratory will also check for signs of other problems, such as infections.

Sperm count often fluctuates significantly from one specimen to another. For this reason, several semen analysis tests may be done over a period of time to ensure accurate results.

If a male’s sperm analysis is normal, a specialist is likely to recommend thorough testing of the female partner before recommending any more male fertility tests.

What Causes Sperm Disorders?

There are many possible causes of sperm disorders, including:

• Anatomical abnormalities such as varicocele (varicose veins of the testicle) or history of an undescended testicle(s)
• Environmental and lifestyle factors such as heavy use of tobacco, alcohol, steroids, marijuana, or exposure to toxins
• Hormone or pituitary gland problems
• Use of testosterone or workout supplements
• Genetic disorders such as being a carrier for cystic fibrosis or having an extra or misplaced portion of a chromosome
• Medical problems such as a history of cancer or uncontrolled diabetes
• Serious childhood illnesses
• Childhood surgeries, including hernia repair or testicular injuries
• Kidney or liver infections, other infections, inflammatory conditions,
• Vasectomy

Azoospermia

The complete absence of sperm in the ejaculate is called azoospermia. The cause of azoospermia can be obstructive or non-obstructive. Obstructive azoospermia may be treatable with reconstructive surgery, while non-obstructive azoospermia typically requires sperm retrieval and in-vitro fertilization (IVF).

One frequently used procedure for non-obstructive azoospermia is micro-TESE, in which a reproductive urologist finds and retrieves sperm using an operating microscope.

Treatments for Male Infertility

There are many treatments for male infertility, depending on the specific cause. They include:

• Surgery. Surgery can repair dilated varicose veins in the scrotum (varicocele repair), which can often improve the quality of sperm. An obstructed vas deferens can be repaired to correct infertility. Additionally, sperm retrieval procedures can help men with severely abnormal semen quality, those who are azoospermic (no sperm in the ejaculate), and those with disorders of erection or ejaculation. In men with a history of vasectomy, a vasectomy reversal or sperm retrieval can be considered.
• Hormone medications and treatments. A fertility specialist may recommend hormone medications if infertility is caused by low levels of certain hormones or problems with how hormones are used by the body. Hormonal disorders may be caused by a problem in how the pituitary gland and testes interact, which affects how sperm develop. Treatments might include hormone modulators such as clomiphene citrate or gonadotropin therapy.
• Treating infections. Antibiotic treatment might cure an infection of the reproductive tract. This does not always restore fertility, but in some cases, it does.
• Lifestyle adjustments. A patient’s risk factors will be assessed, and recommendations for healthier life choices might be made, including tobacco cessation, decreased alcohol consumption, avoidance of testosterone and workout supplements, improved sleep, weight loss, and improved diet.
• Treatments for sexual intercourse problems. Medication or counseling can help improve fertility in conditions such as premature ejaculation or erectile dysfunction.
• Assisted reproductive technology (ART). ART treatments involve obtaining sperm through normal ejaculation, surgical extraction, or from donor individuals. The sperm can then be inserted into the female genital tract or used in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI) to achieve pregnancy.
• Artificial insemination. This treatment, also known as intrauterine insemination (IUI), inserts a well-timed, highly concentrated sample of healthy sperm into your partner’s uterus with the hope that the sperm will make their way to the fallopian tubes.
• IVF and ICSI. In vitro fertilization (IVF) and intracytoplasmic sperm injection (ICSI) is assisted reproduction where fertilization and embryo development occurs in the embryology laboratory. The sperm is collected, and a high-quality sperm is selected and injected into your partner’s egg to create an embryo that can be transferred back into the partner’s uterus.

Donor Sperm is an Option for Severe Male Infertility

In some cases, male fertility problems cannot be treated despite the best technologies and medications. At that point, a fertility specialist might suggest that a male and his female partner consider using sperm from a donor.

Anonymous donor sperm can be purchased from a sperm bank and shipped to a fertility clinic for intrauterine insemination (IUI) or in-vitro fertilization (IVF).

When to see an Infertility Doctor

You should consider seeing an infertility specialist if you and your partner have been unable to conceive after a year of unprotected sex and you have any of the following conditions:

• Erection or ejaculation problems, other problems with sexual function, or a low sex drive
• Pain, discomfort, or a lump or swelling in the testicle area
• A groin, testicle, penis, or scrotum surgery in your medical history
• A history of testicle, prostate, or sexual problems
• You are 45 years of age or older
