In Vitro Fertilization in Mice

Cold Spring Harbor Protocols, 2018
The success of in vitro fertilization is strongly influenced by genetic background, handling of sperm and oocytes, and culture conditions. This protocol promotes enhanced rates of fertilization by using preincubation medium for sperm containing methyl-β-cyclodextrin (MBCD) and fertilization medium with high calcium and reduced glutathione (GSH).

Fertilization abnormalities in human in-vitro fertilization

Human Reproduction, 1992
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 ...
