Proteomic technologies have begun providing evidence that viable embryos possess unique protein profiles. Some of these potential protein biomarkers have been identified as extracellular and could be used in the development of a noninvasive quantitative method for embryo assessment. The field of assisted reproductive technologies would benefit from defining the human embryonic proteome and secr...

The field of assisted reproduction is renowned for its remarkable advances and constant pushing forward of research boundaries in an effort to offer innovative and effective methods for enhancing fertility. Accompanying these advances, however, are physiological, psychological, and bioethical consequences that must be considered. These concomitant advances and consequences make assisted reprodu...

We reviewed the literature on assisted reproductive technology (ART) strategies and outcomes for men with large-headed spermatozoa. We also discuss additional analyses that can usefully characterize sperm defects and help with the choice between intra-couple...

Observations have shown that parents possess remarkable implicit communicative abilities allowing them to adapt to the clues infants give and therefore stimulate the development of many of the infants' abilities, such as communication skills. This work focused on ob...

Among the different DNA anomalies that can be present in the male gamete, DNA fragmentation is the most frequent, particularly in infertile subjects. There is now consistent evidence that a sperm containing fragmented DNA can be alive, motile, morphologically normal and able to fertilize an oocyte. There is also evidence that the oocyte is able to repair DNA damage; however, the extent of this ...

This paper provides an appraisal of countries that have legislations pertaining to assisted reproductive technologies (ART). In doing so, the paper highlights the emphasis on the protection of reproductive freedom of the couples seeking ART treatment. This belief is grounded primarily on the basic notion of liberalism that attaches primary importance to respect for individual freedom, which is ...

Surrogacy is especially complex as the interests of the intended parents, the surrogate, and the future child may differ. It is concluded that surrogacy is an acceptable method of assisted reproductive technology of the last resort for specific medical indications, for ...
