Abstract:
Objective To determine if the shortened exposure of oocytes to sperm can influence the insemination rate and the results of IVF-ET. Methods A total of 217 women were included.They were divided into study group (105 cases) and control group (112 cases). In study group the shortened insemination was used.The oocytes were washed 2 hours after the insemination and transferred into the fresh medium.In control group the classical procedure was used.The oocytes were inseminated by ICSI.The number of retrieved oocytes,fertilized oocytes,the number of embryos were counted and the pregnancy rate was evaluated. Results There was no statistically significant difference between the study and control group in the number of retrieved oocytes (1163 vs 1752),number of embryos (1084 vs 1097),and pregnancy rate ( 42.9% vs 42.9%). Conclusions The shortened exposure of oocytes to sperm is a simple and effective way in IVF-ET.
