Effect of Sperm Selection Techniques on Human Neonatal Gender Ratio in Patients Undergoing ICSI

Study Overview
=================
Brief Summary
-----------------
babies of known gender born out of 388 ICSI cycles were investigated for the gender ratio and then divided into three groups according to the sperm selection technique used before performing sperm injection. Statistical analysis were made to compare ratios and compare results of three arms

Detailed Description
-----------------
A total of 529 babies of known gender born out of 388 ICSI cycles between August 2016 and May 2018 at Ganin Fertility Center, Cairo, Egypt, were investigated for the gender ratio and then divided into three groups according to the sperm selection technique used before performing sperm injection; DGC (237 neonates out of 173 ICSI cycles), PICSI (147 neonates out of 109 ICSI cycles) , and MACS (145 neonates out of 106 ICSI cycles). In PICSI and MACS groups. Power analysis was done by comparing the sex ratio of the neonates between DGC, PICSI and MACS. The chi-squared test for independent samples was chosen to perform the power analysis with α-error level at 0.05. P values less than 0.05 were considered statistically significant. All statistical calculations were done using IBM SPSS (Statistical Package for the Social Science; IBM Corp, Armonk, NY, USA) release 22 for Microsoft Windows.
