摘要
The invention relates to chemotactic factors for human spermatozoa that are purifiable from human follicular fluid. The factors are of peptidic and hydrophilic nature and have, one, a molecular size of about 13 kDa and, the other, an apparent molecular size smaller than 1.3 kDa, as determined by high pressure gel filtration. They are for use in procedures related to human fertilization, such as in various types of assisted fertilization, particularly artificial insemination, in vitro fertilization, micromanipulation and direct microinjection of sperm into oocytes.
