Shortly after Dr. Ian Wilmut made international news in 1997 by announcing the successful cloning of an adult sheep, Chicago physicist Dr. Richard Seed made an announcement of his own that caused similar alarm. At a law school symposium on reproduction, the Harvard-educated physicist announced plans to perfect cloning procedures and then to open a human cloning clinic for infertile couples. At ...

Research showed that following the birth of a first child, parents increase contact with family members and diminish contact with friends, however, these changes may differ when conception is achieved through assisted reproductive technologies (ART). Based on the convoy model (Kahn & Antonucci, 1980) perspective of close relationships, we examined changes across the transition to parenthood in ...

Assisted reproductive technologies (ARTS) are used for more than 30 years to help infertile couples. Concerns about long-term health of children conceived following ART have led to start follow-up studies. Despite methodological limitations and discrepant results, many of the studies and meta-analyses have reported an increased risk of birth defects after ART. Etiologies may be multiple births,...

recent advances in reproductive medicine have created a demand for more accurate and safe imaging modalities before assisted reproductive treatment(art) (1). gradually, the important role of three-dimensional (3d) ultrasonography in the diagnosis of uterine congenital anomalies has been proved (2-4).

OBJECTIVE To determine differences in use of the Internet related to infertility between infertile women and men, whether they benefit or are negatively affected from information on the Internet, and share this information with health professional. METHODS This cross-sectional study was carried out with 285 infertile women and 158 men between December 2015 and February 2016. Data were collect...

SETTING Not applicable. PATIENT(S) A total of 7,608 fresh autologous ART ET cycles. INTERVENTION(S) None. MAIN OUTCOME MEASURE(S) Live birth. RESULT(S) Generalized estimating equation (GEE) models and re...

BACKGROUND Over the past 10 years, there has been a significant increase in the use of assisted reproductive technologies in Canada, however, little is known about the overall prevalence of infertility in the population. The purpose of the present study was to estimate the prevalence of current infertility in Canada according to three definitions of the risk of conception. METHODS Data from t...

In a non-matched case-control study using data from two large national cohort studies, we investigated whether indicators of child health and development up to 7 years of age differ between children conceived using assisted reproductive technology (ART), children born after sub-fertility (more than 24 months of trying for conception) and other children. Information on ART use/sub-fertility was ...

One of the plots of the Canadian science fiction thriller Orphan Black involves a scheme to create dozens of siblings by harvesting the eggs of one woman, fertilizing them with the sperm of a single man, and implanting them for gestation in dozens of apparently willing surrogates.¹ The casualness of the procedure speaks to how comfortable we have all become with reproduction by technology. Yet ...
