title: Successful management of infertility due to polyzoospermia.
abstract: Polyzoospermia is a rare cause of male infertility. In our clinical practice, patients with exceedingly high sperm counts (ranging from 650 million/ml to 1.75 billion/ml) have invariably been found to have associated poor sperm motility and poor sperm migration in postcoital tests, although the sperm appear morphologically normal. Cases of two infertile couples are presented in which each husband had sperm counts greater than 1 billion/ml. Two methods are reported for the successful management of their infertility problems: (1) precoital dilutional douching and (2) in vitro seminal fluid dilution with 5% dextrose-Ringer's lactate solution and artificial insemination homologous. Each method resulted in improved sperm motility, postcoital tests, and pregnancy.
