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 mOsm/L NaCl 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% CO2 at 37°C after in vitro sperm preparation. Results: 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).
Hyaluronic acid (HA) is a polysaccharide, that composed in the extracellular matrix of the cumulus cells, and considered to take function in choosing mature spermatozoa. The Sperm-hyaluronic binding assay (HBA) is significant diagnostic instrument for suspected male infertility when examining the semen. The HBA slide supplies the ratio of mature binding sperm in the specimen. To evaluate sperm parameters, and to evaluate the (HBA Score percentage (%) before and after activation. Twenty-five infertile couples a sharer in this current study through their attendance to the Al Nahrain University. Males undergoing seminal fluid analysis were done according to (WHO 2010, and WHO 1999). Sperm parameters assessed and calculate the HBA Score% pre-and-post-direct swim-up technique, the results were statistically tested. In Post-activation there was considerable increment noticed in the progressive motility and morphology of spermatozoa, likewise significant improvement in the (HBA score %). Furthermore, considerable reduction in the concentration, agglutination of spermatozoa and round cells count, when compared to pre-activation. The mean of binding of spermatozoa to hyaluronan pre-activation (direct swim-up technique) was less than normal limit for normozoospermic males. However, it significantly improves post-activation.
