Mikkelsen AL, Lindenberg S. Total FSH dose was considered a potential intermediate variable and was therefore not adjusted for. This study, thus, indicates that within the purview of current embryology practice the potential predictive value of detailed oocyte assessments is underappreciated.

Oocyte activation and parthenogenetic development of bovine oocytes following intracytoplasmic sperm injection. After that, only spermatozoa bound to the HA drop were selected and subsequently injected into the oocytes as described above by the ICSI method. Increasing the cAMP concentration during in vitro maturation of pig oocytes improves cumulus maturation and subsequent fertilization in vitro. Hyaluronic acid binding by human sperm indicates cellular maturity, viability, and unreacted acrosomal status. However, co-culture of DO with granulosa cells does not reestablish gap junctions and IVM rates remain low. Atretic oocytes or oocytes with broken zonas are not viable and are unable to be fertilized.

Logistic regression adjusted for age demonstrated a significant relationship between the average PTOS and clinical pregnancy OR 1. The present large-scale study showed that in terms of individual static embryo evaluation parameters of embryo cleavage rate and morphology, the age-associated changes are primarily subtle. Fertilization can be summarized as the union of two nuclei within the activated oocyte cytoplasm one coming from the sperm and one from the oocyte containing the genetic material of both parents.
