title: ["In vitro" glass fiber filtration of sperm (author's transl)].
abstract: Filtering sperm through glass fiber has been suggested as a method for improving its fecundity before homologous artificial insemination. Various technical modification of this procedure have enabled good results to be obtained on spermatozoid mobility but at the expense of a marked drop in numbers: sperm counts per ml are diminished by a half. A comparative in vitro study of the penetration of filtered and non-filtered sperm into the cervical mucus showed that glass fiber filtration produced generally no great improvement, and may indeed reduce penetration into the cervical mucus to a marked degree in some cases.
