Abstract Study question Is the risk of long-term respiratory morbidity increased among children born following fertility treatments (in-vitro fertilization and ovulation induction)? Sibling analysis to maximize confounder control. Summary answer Fertility do not appear be an independent factor for offspring up 18 years age. What is known already Studies have found association between offspring,...

Moreover, when we look still more closely at the life bush, examining in detail the various lineages that form the littlest twigs (the species), we see the same pattern over again. The vast majority of individual animals and plants forming these various lineages didn't make it. The twigs are largely made of fuzz--of myriad little lives that broke off before reproduction. To a first approximatio...

HASTINGS CENTER REPORT 17 Many donor-conceived individuals want to know their genetic origins. This has become a growing issue of public debate and bioethical concern. Some concentrate on their interest in donors’ medical and genetic information, which can be relevant to medical decision-making. Others emphasize broader interests in donors’ personal information, which could help donor-conceived...

background: assisted reproductive technologies (art) are known as a treatment for infertility in which oocyte undergoes manipulation outside body. the aim of this study was to study the evaluation of birth defects in infants conceived through assisted reproductive technologies (art) and compare them with naturally-conceived infants. materials and methods: in this retrospective study, four hundr...

The proximate mechanisms that regulate transitions in mammalian female reproductive effort have not been widely studied. However, variation in circulating levels of the androgenic steroid hormone testosterone (T) appears to mediate a trade-off between investment in current and future offspring in males [Ketterson, E.D., Nolan, V., Jr., 1992. Hormones and life histories: an integrative approach....

Testicular cancer (TC) is the most curable type of cancer, with a survival rate of more than 95%. Oncologists are faced with the challenge that gonadotoxic cancer treatments can compromise future fertility, either temporarily or permanently. Our aim was to investigate the long-term effects of TC treatments on male fertility and on the offspring of patients who had received these treatments. Bet...

Obesity in the childbearing population is increasingly common. Obesity is associated with increased risk for a number of maternal and neonatal pregnancy complications. Some of these complications, such as gestational diabetes, are risk factors for long-term disease in both mother and baby. While clinical practice guidelines advocate for healthy weight prior to pregnancy, there is not a clear di...

INTRODUCTION In their article, ‘Gamete donor anonymity and limits on numbers of offspring: the views of three stakeholders’, Margaret K. Nelson, Rosanna Hertz and Wendy Kramer draw on survey data from gamete donors, parents who used gametes to conceive, and donor-conceived offspring in order to understand the position that various stakeholders are likely to hold regarding the regulation of two ...
