“…While studies have found HA bound sperm to be associated with low DNA fragmentation [7,8] there have been conflicting reports with regards to clinical outcome. While Nasr-Eshafani et al [8] reported an increase in fertilization rate and Parmegiani et al [9] showed an improvement in embryo quality and implantation rates after injection of HA bound sperm, Menezo et al [12] found no difference in embryo quality or clinical pregnancy rates in HA-ICSI as compared to PVP-ICSI.…”

“…It has also been reported that sperm that can bind to HA have a reduced risk of being anueploid [6] or having fragmented DNA [7,8]. Initially, a number of studies have suggested a beneficial effect of HA sperm selection on assisted reproductive technology (ART) outcomes [7][8][9][10][11]. However, recently a large study comparing ICSI using HA and conventional ICSI showed no statistical difference in embryo quality and pregnancy rates [12].…”

Purpose Sperm quality plays an important role in determining embryo development and intracytoplasmic sperm injection (ICSI) outcome. Selection of competent sperm based on its ability to bind to hyaluronic acid (HA) has been suggested as one of the methods to assess sperm quality. The aim of the present study was to examine whether injection of HA bound sperm helps in improving outcome in patients undergoing ICSI with unexplained infertility having normal semen parameters. Methods Patients with unexplained infertility having normal semen parameters in accordance with WHO 2010 criterion, undergoing their first IVF-ICSI cycle were enrolled during the course of the study.156 patients were prospectively randomized after oocyte retrieval and were assigned to either the ICSI group, where sperm selection for injection was based on visual assessment, or the PICSI group, where sperm were selected based on their ability to bind to HA. Only fresh embryo transfers were included in the analysis. Results There was no difference in the fertilization rates, number of top quality embryos and clinical pregnancy rates between the ICSI and PICSI groups (65.7 % vs 64.7 %; 45.8 % vs 43.6 % and 35 % vs 35.2 % respectively). However, a higher pregnancy loss rate was observed in the ICSI group (25 % vs 12 %; P =0.227) as compared to the PICSI group, but the difference was not statistically significant. Implantation rates were 22.03 % and 18.84 % in the PICSI and ICSI groups respectively. There were 22 (31 %) live births in the PICSI group and 21(26.3 %) live births in the ICSI group. Conclusions Patients with unexplained infertility having normal semen parameters may constitute a patient group which does not benefit from this sperm selection method. A larger study may be necessary to establish a relationship between PICSI and pregnancy loss rate in patients undergoing IVF with unexplained infertility.

“…Studies documenting the use of sperm selected by HA method in the clinical ART setting are still scarce and somehow contradictory. While one study reported significantly increased fertilization rate of oocytes injected with HA-selected sperm and only a marginal effect on pregnancy rate (Nasr-Esfahani et al, 2008), in other studies by Permegiani et al (2010a;2010b) oocytes injected with sperm selected by the binding method originated better quality embryos but no effect was detected on fertilization and pregnancy rates.…”

“…This, and related work, suggest that spermatozoa capable of binding to hyaluronic acid have completed their maturation processes, most specifically plasma membrane remodelling and full chromatin condensation, and subsequently have an increased fertilizing capacity (Cayli et al, 2003;Huszar et al, 2003;Mokanszki et al, 2014). Different studies have suggested that hyaluronic-acid-binding improves embryo quality and development after ICSI, although all these studies were relatively small (Nasr-Esfahani et al, 2008;Parmegiani et al, 2010a;Parmegiani et al 2010b;Mokanszki et al, 2014;Beck-Fruchter et al, 2015).…”

AbstractMature spermatozoa bind hyaluronic acid in the extracellular matrix via hyaladherins.Immature spermatozoa may be unable to interact because they do not express the appropriate hyaladherins on their surface. Fresh human semen samples were fractionated using differential density gradient centrifugation (DDGC) and the ability of these fractions to bind hyaluronic acid was evaluated. The presence of sperm hyaladherins was also assessed. CD44 was located mainly on the acrosome and equatorial segment and became more restricted to the equatorial segment in capacitated spermatozoa. Hyaluronic acid-TRITC (hyaluronan acid conjugated with tetramethylrhodamine isothiocyanante), a generic hyaluronic-acid-binding reagent, labelled the membrane and the neck region, particularly after capacitation. Sperm populations obtained after DDGC or after interaction with hyaluronic acid were assessed for DNA fragmentation and chromatin maturity. Strong relationships between both measures and sperm sedimentation and hyaluronic-acid-binding profiles were revealed. Capacitation Overall success rates for assisted conception procedures, however (including ICSI), have remained relatively static, with about 24% of cycles for all age groups deliverin...
