Abstract excerpt
The sequential transformations of human sperm nuclei in human eggs after subzonal insemination (SUZI; n = 104) and the influence of sperm defects on this timing were studied. This chronology was compared to that of two control series of zygotes obtained after SUZI with normal spermatozoa (n = 35) and after in-vitro fertilization (IVF) with normal donor spermatozoa (D-IVF; n = 220). Pronuclear formation took place...
