At Shady Grove Fertility, we will perform a semen analysis prior to any treatment cycle to evaluate your sperm's potential to fertilize the egg. Some of the parameters we check for in a semen analysis include:
- Sperm count (concentration)
- pH (level of acidity)
- Motility (movement)
- Progression (motion and forward progression)
- Semen viscosity (consistency)
- Morphology (shape and appearance)
- The presence or absence of white, red blood cells, or immature sperm
Certain medications or a medical problem such as a blocked duct, a low testosterone level, or a condition in which sperm back up into the bladder can cause a low sperm count. Fever can also reduce sperm count.
Low testosterone, also called low T, occurs when a man has testosterone levels that are below normal levels. The condition—defined as a combination of sexual symptoms and measured testosterone level—is actually quite rare (affecting only 0.1 percent of men in their 40s, 0.6 percent in their 50s, 3.2 percent in their 60s, and 5.1 percent of men in their 70s, according to the British Medical Journal’s European Male Ageing Study). While some men do have this condition, the vast majority do not, in spite of advertising that has led people to believe otherwise. Men should always consult a physician before trying any medications. What does this have to do with fertility? Low T medications have actually been found to sometimes cause a low sperm count, creating the exact opposite effect of what was intended.
In addition, some men may have enough sperm, but their sperm may not swim well enough to reach the egg. Also, sperm that are not normal in shape may not be able to penetrate and fertilize the egg.
Your doctor can treat many of these problems.
How it Works
Before the Semen Analysis
You should abstain from sex or masturbation for at least 3 days before the analysis, but not longer than 1 week. Check with your doctor to see if there are any other recommendations specific to you.
During the Semen Analysis
In order to perform the semen analysis, your doctor will want you to provide a semen sample. You may collect the sample by masturbation at one of our offices in a private, comfortable room (please check for room availability before you choose this option). One of our clinicians will ask you to collect your semen in a sterile specimen cup. Another option is to collect your semen at home by masturbation or during intercourse in a special condom that you can get from your doctor. You must deliver your sample to our office within 60 to 90 minutes of collecting it (please check for specific drop-off office availability). Speak with your doctor about instructions for transporting the sample to the office. In some cases, you will need to repeat testing (e.g., small sample size, abnormal test result). Because test results often vary, you may need to repeat testing more than once.
Semen analysis results are generally available within a few days. If test results are abnormal, your physician may diagnose one or more of the following conditions:
Low sperm count
A low sperm count is fewer than 15 million sperm per milliliter ejaculated. The normal range is between 40 million and 300 million sperm per milliliter of ejaculation. Certain medications or a medical problem such as a blocked duct, a low testosterone level, or a condition in which sperm back up into the bladder may cause a low sperm count. Fever can also reduce sperm count.
Motility describes the movement of the sperm. Some men may have enough sperm, but their sperm may not swim well enough to reach the egg. Low motility may reduce your chances to conceive, especially if your sperm count is also low. In a normal semen sample, at least 40 percent of the sperm have appropriate movement.
A normal sperm has an oval head, slender midsection, and a tail that moves in a wave-like motion. Sperm that do not have this normal shape may not be able to swim effectively or penetrate the egg.
Your doctor will be able to treat many of these potential diagnoses. In the event that severe male factor infertility is present, intracytoplasmic sperm injection (ICSI) has made it possible for patients to conceive using their own sperm.
