PURPOSE The recent trends of multiple births (MBs) conceived by assisted reproductive technology (ART) in Korea were analyzed as well as the relationship with maternal age, especially advanced maternal age. METHODS Data were obtained from the Korean Statistical Information Service and annual ART reports from the ART committee of the Korean Society of Obstetrics and Gynecology. RESULTS MBs i...

BACKGROUND It has been suggested that couples who conceive with assisted reproductive technologies (ART) invest more in their child than those who conceive spontaneously. This study examined how parental investment in the child (PIC) varied as a function of method-of-conception, gender and other contextual variables, i.e. prenatal depression, social support and satisfaction with the marital rel...

Assisted reproductive techniques have been a great blessing for the infertile couple. Some have questioned their use, citing the unknown risk to the unborn child. The emergence of one of the newest techniques, intracytoplasmic sperm injection, has again sparked debate on the ethics of assisted reproductive techniques. Those who oppose intracytoplasmic sperm injections use are primarily concerne...

Heterotopic pregnancy is defined as intrauterine and extrauterine pregnancy entity coexisting simultaneously and which has been on the rise in recent years with the development of assisted reproductive techniques. We report 4 cases of heterotopic pregnancy, three of them resulting from assisted reproductive technologies and a spontaneous case. We also describe the methods used for diagnosis, th...

Scholars of differing political affiliation and the President's Council on Bioethics have called for regulation of assisted reproductive technology (ART) that would emulate many aspects of the regulatory system of the United Kingdom, in particular that of the Human Fertilisation and Embryology Authority. Specifically, scholars and the Council have argued that research in the U.S. involving game...

This article argues that legal determinations of filiation are normative ideological constructions about how societal relations between parents and children should be ordered. They are based upon regular understandings of the relationship between biological and social facts and, as this article demonstrates, operate to create an asymmetrical relationship between the categories between paternity...

Genetic causes have a considerable involvement in infertility. Well-known examples are some chromosomal translocations or sex-chromosomal abnormalities and Y-chromosome deletions. The most common chromosomal aberrations associated especially with severe oligo- and azoospermia are sex chromosome aneuploidies and chromosomal translocations. Consequently, occurrence of aneuploid embryos will lower...

In vitro fertilization, popularly referred to as IVF, has captured the attention of the public since its sensational introduction in 1978. Today assisted reproductive technology is available throughout most of the civilized world, and the practice is largely different from that used during the early days. Refinements in laboratory technology and clinical practice have allowed IVF to evolve into...

Lineage in the Islamic law is one of the most basic human rights each individual inherits from his family. When modern assisted reproductive technologies appeared in recent decades, the issue of lineage and the child's rights did not encounter serious challenges. But with the advent of these technologies, the issue of the child's lineage resulting from new technologies has become the center of ...

Introduction Assisted reproductive technologies (ART) are changing the legal definitions of parenthood. The severing of genetic ties from gestational ones and from the social aspect of parenting has resulted in courts having to revise traditional definitions of mother and father. This has led to a legal construct known as “intended parenthood,” in which biological ties are sometimes subordinate...
