Glass Wool Filtration of Human Semen

Abstract

Various modes of treatment aimed at improvement of sperm production and the quality of the ejaculate of the subfertile male may be rewarding. In vivo treatment of these individuals, however, has not yielded good pregnancy rates, as often treating the cause of such problems is difficult as the etiology is unknown, so it is theoretically easier attempting to improve the specimen once ejaculated. The addition of pharmacological agents to the ejaculate yields better in vitro specimens, but the effect of insemination on pregnancy rates is still being explored. A glass wool column which increases the motility of the spermatozoa while removing dead and agglutinated spermatozoa and debris from the ejaculate has been devised and the results from its use are encouraging for specific problems.
