Micro-analytic research on intuitive parenting behaviors has shed light on the temporal dynamics of parent and child interactions. 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...

OBJECTIVE To provide an in-depth analysis of offspring attitudes toward their means of conception and the practice of sperm donation in the United States. DESIGN Survey-based study using a 46-item questionnaire. PATIENT(S) Eighty-five adult offspring of sperm donation. INTERVENTION(S) Participants were recruited through an Internet-based support group for adults conceived through sperm do...

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 10th statement of the Task Force on Ethics and Law considers ethical questions specific to varied surrogacy arrangements. 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 ...

OBJECTIVES We examined the prevalence of Early Intervention (EI) enrollment in Massachusetts comparing singleton children conceived via assisted reproductive technology (ART), children born to mothers with indicators of subfertility but no ART (Subfertile), and children born to mothers who had no indicators of subfertility and conceived naturally (Fertile). We assessed the natural direct effect...

background: approximately one percent of current live births of the world are conceived via assisted reproductive technologies (art). objective:  the purpose of this study was to compare the developmental status of children born through assisted and natural conceptions at the age of five years. materials and methods:  in a retrospective cohort study, developmental status of 5 years old children...

The development of assisted reproductive technologies (ART) arises from the need to improve reproductive conditions, ensuring births in humans. Progress in this area of research has enabled the possibility of sperm selection with adequate morphological characteristics to ensure fertilization, embryo development, pregnancy and birth. However, further studies are required to increase reproductive...
