Fertility Testing At Home: Sperm Testing

test cupOver the past few years,  more and more fertility tests have become available for home use. This month one of the leading journals in the fertility world, Fertility and Sterility, published a very nice review of many of these home tests. Coincidentally, I just gave a talk about many of these tests and thought I would share my thoughts about them.

For the sake of time and space, I’ll tackle these one at a time. Today, we’ll talk about home sperm testing.

One of the tenets of good medical practice is to treat the patient, not just the test.
Make an Appointment

Before we get there, let me give some background.

The idea of home testing fits a definite need among consumers. It’s nice to be able to learn that you’re pregnant without making a doctor’s appointment. It’s also nice to identify problems early, if that leads to evaluation and effective treatment.

The problem with a lot of tests on the market is that they can be falsely reassuring and may cause some people to delay proper evaluation. There is no good evidence that performing such tests actually improve a couple’s chance of conception. A patient without a history of infertility is most likely wasting  his or her money. On the other hand, if a couple has not conceived within one to two years of unprotected intercourse, I’m not sure that any home test is particularly reassuring. A falsely reassured patient may delay treatment and therefore is at risk for not meeting their reproductive dreams.

Several years ago after hearing a story about home fertility testing on NPR’s “All Things Considered,”  I wrote a letter describing some of the pitfalls of such testing. The two tests described were a semen test and a test to measure a woman’s FSH, marketed under the name Fertell by Genosis Ltd.

The Fertell sperm test can determine if a man has 10 million total motile sperm and costs about  $100. The advantage of this test is that many men are embarrassed to have a formal semen analysis performed. Also, the test determines the motile concentration, which is fairly predictive of normal fertility. Recently, the World Health Organization (WHO) published findings showing that 95 percent  of fertile men had a sperm concentration of 15 million sperm/ml,  32 percent  were progressively motile and 5  percent  or more had a normal shape. A reassuring Fertell tests should correlate well with two  of those  three  parameters. If abnormal, the test should lead a man to have further testing performed.

The drawback to the Fertell sperm test is that it does not test morphology, which can be very important. The cost is also a drawback. For an additional $50, a patient can have a full semen analysis at our clinic and have it reviewed by a physician who can interpret the results in the context of the couple.

Other home semen tests are also available. Embryotech has marketed several tests (FertilMARQ, Start Male Infertility Test and PreConceive: A Male Fertility Sperm Test) that purport to evaluate sperm concentration. Because each tests only a single parameter (concentration),  they tell  nothing about motility or morphology. A man with few or no moving sperm may be falsely reassured. (As with the Fertell test, an abnormal result should be followed up with a visit to a physician’s office.)

There are also small microscopes available. The disadvantage of this test is that interpretation is left up to the patient. As with all home testing, the disadvantage to the home microscope is that there is no one with clinical experience to interpret the test in the context of the couple.

As I said above, a normal test does not mean that all is well. A person without infertility may find this test reassuring; however, this person probably doesn’t need the test in the first place. A full semen analysis gives significantly more information than any of these tests. A couple with infertility is probably better off having a medical evaluation by a knowledgeable physician. However, if the only way to get a man to get tested is with at an at home test, I would pick Fertell  because  it gives the most information with the easiest interpretation.
