TL;DR: Spermatozoa selection at high magnification before intracytoplasmic sperm injection seems to be positively associated with pregnancy rates after day 3 embryo transfers and 'early and late paternal effects', both of which may have an impact on early embryonic development are confirmed.

TL;DR: Combinations of adverse lifestyle factors could have a detrimental impact on sperm, not only in terms of motility and sperm count but also in Terms of sperm head vacuolization.

TL;DR: Early morphokinetic parameters might give some predictive information but fail to serve as a feasible selective tool for the prediction of blastocyst development given the influence of the type of spermatozoa injected.

TL;DR: It is concluded that nuclear vacuoles on the sperm head are already produced at earlier stages of sperm maturation and are not induced or modulated by routine laboratory environments.

TL;DR: The implementation of intracytoplasmic sperm injection in 1992 gave women whose male partners were diagnosed with severe male factor infertility the chance of having a baby using their partner’s own ejaculated or testicular spermatozoa, but fertilization is dramatically reduced in some cases and does not even occur in 1–3% of ICSI cycles.
