P-58: Which Novel Sperm Selection is Suitable for ICSI? MACS-DGC or DGC-MACS
Background: Super-paramagnetic annexin-V conjugated micro-beads are able to eliminate sperm with phosphatidylserine externalization (PSE). PSE is considered as apoptotic sperm. PES positive sperm can be removed from sperm preparations sample to enhance sperm quality for assisted medical procreation. Therefore, the efficiency of this technique over normal sperm processing procedure such as densi...

متن کاملO-14: New Era in Sperm Selection for ICSIProcedure
Background: Intra-cytoplasmic sperm insemination, the ICSI, is considered as the one most routine treatment of male infertility. Although the genetic inheritance of an individual is based on the genetic contribution from both the oocyte and sperm, considering the fact that ICSI by passes all the barriers to natural fertilization much emphasis was given to oocyte quality to improve the ICSI outc...
متن کاملComparison of Different Sperm Selection Techniques in Ram Frozen - Thawed Sperm
Background: The success of fertilization is directly associated with semen quality and the sperm preparation. Considering the common use of cryopreserved spermatozoa, there is a need to develop strategies for sperm preparation in order to achieve a sperm sample of high quality through a rigorous selection of sperm. Thus, sperm cells are being more extensively investigate. This study aimed evalu...
متن کاملP-83: Which Novel Sperm Selection Method Is Functional? MACS-DGC or DGC-Zeta
Background: Selection of human spermatozoa prior to assisted reproduction is currently based on motility and morphology. Recently, Zeta method has been introduced for normal sperm selection based on sperm surface charges. In addition, one of the features of apoptosis is the externalization of phosphatidylserine (PS), which are normally present on the inner leaflet of the sperm plasma membrane. ...
