Abstract
Background; The sperm plasma membrane activity and absence of antisperm antibodies in infertile patients ejaculate significantly associated with fertilization potential of human spermatozoa. The sperm viability detected by hypoosmotic swelling test (HOST) and autoimmune infertility detected by antisperm antibody assay presented diagnostic and prognostic tools for male infertility factors. Objective: This study was devised to compare the results of hypoosmotic swelling test and antisperm antibody assay for normozoospermic men and infertile patients affected by autoimmune infertility Methods: Thirty semen samples were collected by masturbation and prepared by direct layering technique. Hypo-osmotic swelling test was performed by mixing 0.1 ml of semen with 0.9 ml of a 150 mOsmI L NaCI as a hypo-osmotic solution and direct immunobead assay were used to determine the presence of Antisperm Antibodies (ASA) bound on sperm surface. However, sperm concentration, sperm motility, and normal sperm morphology were evaluated according to World Health Organization (WHO) criteria and subjected to HOS test and ASA assay. The sperm prepared and incubated for 30 minute in 5% C02 at 37°C after in vitro sperm preparation. Result*: The results of the present study reported that the percentage of HOS test score in antisperm antibodies positive sperm samples (52.30 ± 5.2) was significantly lower than that noticed in antisperm antibodies negative (70.30 ± 3.4) sperm samples. Conclusion: It was concluded that the use of HOS test as a simple and diagnostic and prognostic tools for identify male infertility. Further studies are suggested to assess the effect of ASA on sperm plasma functional integrity after ICSI and in vitro fertilization and embryo transfers (IVF-ET).
