Abstract
Sperm mobility and impregnation of an oocyte is enhanced by placing sperm in an aqueous solution of phospholipids prior to in vitro fertilization or artificial insemination. The aqueous phospholipid solution can also be used during storage or cryopreservation of the sperm. Also, the motility of sperm produced or ejaculated and the environment into which it is placed is enhanced my ingestion of the phospholipid composition by the male or female, or a vaginal placement of compositions containing the phospholipids.
