“…Álvarez Sedó et al (2011) conducted a study in males with positive apoptosis markers, in order to assess whether MACS effects are impacted by oocyte quality depending on age (group 1 <37 years and group 2 > 37 years). They found a significant difference between both groups with improvement in embryo quality, pregnancy and implantation rates in group 1.…”

Objective: To identify the effect of apoptotic sperm elimination with MACS in patients that require IVF. Methods: An experimental, cross-sectional, descriptive, prospective and non-blinded study of diagnostic tests performed in patients who required IVF and ICSI from July 2011 to July 2012. Ninety-two couples participated according to the treatment administered to the semen sample; in the control group: the samples were subjected only to density gradients before ICSI, in the study group: the same procedure was performed plus the addition of the MACS technique. Comparing the groups, we assessed the fertilization, division, viable embryos and clinical pregnancy rates in all cases. Results: We found significant differences when using MACS technique in sperm parameters. We found no differences between the total samples of the control and study groups. When separating the own and donated eggs in each group, we found an improvement in the fertilization rates ( p <0.001) of the own eggs. In both groups, the handling of donated eggs lead to a significant improvement in the immunological pregnancy test (IPT) and fetal heart rate (FHR) results. Only in the donated eggs group, where MACS was applied, could we see that all cases with positive IPT had a fetal heart rate, which shows a significant difference ( p <0.002) when compared with the control group, where the percentage decreased abruptly. Conclusions: This study demonstrates the effectiveness of the use of annexins (MACS) in eliminating apoptotic sperm, and when the obtained sperm is applied to good-quality eggs.
