The device is an advance on the SpermCheck Vasectomy technology, also developed by Herr, which is already cleared by the FDA.
By measuring sperm levels at 20 million sperm per milliliter and 5 million sperm per milliliter, Herr says that men can determine if they have normal levels of sperm, low levels (between 5 million and 20 million per milliliter) and very low sperm levels (below 5 million).

"The SpermCheck Fertility test is designed as a first line assay for use by couples who suspect infertility. The test is also useful for men of any age who simply want to know if their sperm count is in the normal range. After reading the results couples can determine whether to seek comprehensive clinical evaluation of the male partner's fertility status," Herr said.

A third product, SpermCheck Contraception, is now undergoing testing in a multi-center, NIH-funded study that is evaluating the effectiveness of a new contraceptive drug for men.
Once a man starts using one of the current experimental male contraceptives, which are based on steroid compounds, sperm counts decline over a period of several months.
The SpermCheck Contraception device could serve as a companion product to help men determine when sperm counts have reached safe levels should a male contraceptive drug or device become available in the marketplace.
The new test has been described in the March 2010 issue of the journal Human Reproduction.
