Fertilization abnormalities in human in-vitro fertilization

1 Jun 1992

Abstract excerpt

Fertilization abnormalities (premature chromosome condensation of spermatozoa (PCC), triploidy, haploidy) were analysed in order to determine their origin. PCC occurs in 9% of unfertilized oocytes and seems to be the consequence of a failure of oocyte activation, leading to the continuing presence of cytoplasmic chromosome-condensing factors, causing the sperm nucleus to undergo chromosome condensation...
