Sperm Antibodies and Human Fertilization

American Journal of Reproductive Immunology and Microbiology, 1988
ABSTRACT: Previous investigations using zona‐free hamster oocytes and salt‐stored human zonae pellucidae, and retrospective analysis of routine human in vitro fertilization (IVF) results have suggested that sperm antibodies can impair the fertilizing capacity of human spermatozoa.

2003
The male partner is now recognized as the single most common contributor to a couple’s reason for infertility, with sperm defects accounting for around 30–50% of cases presenting to infertility clinics (Hull, 1992). A standard semen analysis, in particular the assessment of sperm concentration and motility, should therefore always be viewed as a ...
