Apoptosis in human unfertilized oocytes after intracytoplasmic sperm injection.
OBJECTIVE To investigate the presence of programmed cell death in unfertilized oocytes after intracytoplasmic sperm injection (ICSI), assuming that previous apoptotic events could be correlated with the fertilization failure. DESIGN Comparison of the rate of DNA fragmentation in human oocytes at different stages of maturation soon after pick-up (control) and in unfertilized oocytes after ICSI...
متن کاملEfficiency of laser-assisted intracytoplasmic sperm injection in a human assisted reproductive techniques program
OBJECTIVE Laser-assisted intracytoplasmic sperm injection (LA-ICSI), also known as micro-opening or thinning of the zona pellucida (ZP) prior to ICSI, may help to reduce mechanical damage to the oocyte during the procedure. The aim of the present study was to evaluate and analyze the efficacy of our institutional LA-ICSI program, which features laser-assisted ZP thinning prior to ICSI, in compa...
متن کاملImpact of Intracytoplasmic Sperm Injection in Human Assisted Reproduction
The development of assisted reproductive technologies (ART) arises from the need to improve reproductive conditions, ensuring births in humans. Progress in this area of research has enabled the possibility of sperm selection with adequate morphological characteristics to ensure fertilization, embryo development, pregnancy and birth. However, further studies are required to increase reproductive...
متن کاملHuman Sperm Aster Formation and Chromatin Configuration in Rabbit Oocytes Following Intracytoplasmic Sperm Injection Using a Piezo-Micromanipulator
In human fertilization, the sperm centrosome nucleates a radial array of microtubules called the sperm aster. The sperm aster is responsible for apposition of male and female pronuclei, and later gives rise to the first meiotic spindle. The objective of this study was to determine microtubule assembly and chromatin configuration in rabbit oocytes following intracytoplasmic injection with human ...
متن کاملNew Trends in Assisted Reproduction Techniques: Cryopreservation, In vitro Fertilization, Intracytoplasmic Sperm Injection and Physiological Intracytoplasmic Sperm Injection
Since that historically the first human birth was registered through in vitro fertilization in 1978, the improvement and creation of new assisted reproduction techniques such as intracytoplasmic sperm injection and physiological intracytoplasmic sperm injection have become of great importance nowadays. Louise Brown was the first baby conceived through in vitro fertilization in England. Since th...
