Interested in self-diagnosis of fertility? The ability to screen for fertility in private, on one’s own schedule, with an at home diagnostic kit is an appealing option. A company from the UK, Genosis, has developed such a kit, called Fertell.
Fertell is a testing kit that offers a basic assessment of male and female fertility.
Fertell for the male is a specimen collection and testing kit that measures the concentration of motile sperm. A sperm specimen is collected into a cup and allowed to liquefy and then warmed to body temperature. Motile sperm pass through a filter and are colored red by exposure to a gold-coated antibody. Appearance of two red lines in a testing chamber indicates a sperm count over 10 million total motile.
Fertell for the female is a conventional urine test strip very similar to an ovulation prediction kit. The female places the absorbent tip in her urine stream for 5 seconds. FSH in the urine reacts with antibodies on the test strip and shows as a red line in the result window. The intensity of this line reflects the FSH concentration (the darker the line, the more FSH present in urine). High FSH levels are indicated by two dark red lines.
Traditional semen analysis measures sperm volume, count, and motility. Multiplied together, these numbers yield the total motile sperm count, that is, the number of moving sperm in the ejaculate. Total motile sperm count is a reasonable predictor of fertility for men. Fertell establishes that the sperm count is over a specific value of 10 million total motile, a reasonable threshold for male fertility.
The male test kit is not able to determine subtle gradations of male fertility. It cannot detect the effects of treatment or change in lifestyle that may cause improvement in sperm count, nor can it detect alterations in sperm morphology (shape). More sophisticated testing is available at a sperm lab.
The female test kit is used as a screening test, and cannot detect subtle gradations in FSH levels, or the relationship of FSH to other important hormones such as estradiol. Such issues have dramatic effect on the patient’s prognosis.
Neither of these tests can replace an expert’s opinion. An expert’s ability to interpret test results with a broad knowledge base and experience remains the best way to diagnose and treat infertility problems.
Of primary importance is that, while both test kits have been correlated with existing assays, neither has been evaluated for its ability to predict pregnancy. Such research takes time, and hopefully will be forthcoming. For now, Fertell is an interesting option for those seeking a private screening assessment of their fertility.
