First at-home test for vasectomized men proves accurate, easy
A research team from University of Virginia Health System have concluded that the first-at-home test for detecting low concentrations of sperm, known as SpermCheck Vasectomy, can spot sperm count with 96 percent accuracy.
The study work confirmed that the test for vasectomized men is accurate as well as easy to use. "SpermCheck Vasectomy is similar in size and function to a women's home pregnancy test," said the team leader. "It is designed to help couples monitor and confirm that post-vasectomy sperm concentrations have reached infertile levels and avoid any surprises if recanalization occurs," he added.
With help of the SpermCheck, the team evaluated a cohort of 144 post-vasectomy semen samples whether sperm counts were greater or less than a threshold of 250,000 sperm per ml - a level associated with little or no risk of causing pregnancy.
The test proved an accuracy rate of 96 percent in identifying the nonpregnancy level and was 100 percent accurate in identifying whether sperm counts were greater or less than 384,000 sperm per ml.
According to the reproductive experts, when the sperm count is below 1,000,000/ml, there is only a low chance of achieving pregnancy without assisted reproductive techniques such as intra-uterine insemination, in-vitro fertilization and intra-cytoplasmic sperm injection.
Traditionally, the process of detecting concentrations of sperm involve bringing semen samples to a physician's office or laboratory at two- and three-month intervals after the procedure, but with the new test men would be able to monitor the sperm count on their own, that to sitting at home.
