O-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 کاملNew Advances in Intracytoplasmic Sperm Injection (ICSI)
In these last twenty years, intracytoplasmic sperm injection (ICSI) has efficiently permitted the treatment of male factor infertility (Van Steirteghem et al., 1993); the direct injection of spermatozoa into ooplasm has allowed the embryologist to overcome low sperm motility, poor sperm-Zona Pellucida (ZP) binding, and defective acrosome reaction. Although ICSI has been successfully applied wor...
متن کاملI-3: New Advances in Surgical Sperm Retrievals for ICSI in NOA Patients
Background: Nonobstructive azoospermia (NOA) is due to different forms of spermatogenic failure and affects the majority of azoospermic patients. In many NOA cases spermatogenesis was shown to be focal with a “patchy distribution”. Different surgical sperm retrieval techniques have been developed to obtain gametes from the testicles of azoospermic men seeking fertility treatment. Nowadays, test...
متن کاملP-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 کاملP-24: DGC-HOST Method: An Approach for Selection of Normal Sperm during ICSI
Background: During ICSI, motile sperm with normal morphology are selected and injected into oocyte. But integrity of chromatin is not observable. Therefore, researchers are trying for to present novel method of sperm selection with high percentage of normal chromatin. HOST test is a useful assay of functional integrity of the human sperm membrane. We decide to use HOST test after DGC for infert...
