Hermann Joseph Muller's Study of X-rays as a Mutagen, (1926-1927) Kevin M. Gleason Hermann Joseph Muller conducted three experiments in 1926 and 1927 that demonstrated that exposure to x-rays, a form of high-energy radiation, can cause genetic mutations, changes to an organism's genome, particularly in egg and sperm cells. In his experiments, Muller exposed fruit flies (Drosophila) to x-rays, mated the flies, and observed the number of mutations in the offspring. In 1927, Muller described the results of his experiments in "Artificial Transmutation of the Gene" and "The Problem of Genic Modification". 2017-03-07 4 Jul 2018 - 4:40:59am
Hermaphrodites and the Medical Invention of Sex (1998), by Alice Domurat Dreger Mary Drago Hermaphrodites and the Medical Invention of Sex, by historian of science Alice Domurat Dreger, was published in 1998 by Harvard University Press. In the book, Dreger describes how many doctors and scientists treated human hermaphrodites from the late nineteenth century to the early twentieth century. She states that during this time period, many physicians and scientists struggled to determine the nature sex, and to support a classification of sex as male or female, many physicians and scientists resorted to viewing a person's gonads for identification of his or her sex. 2014-04-09 4 Jul 2018 - 4:40:59am
Hilde Mangold (1898-1924) Maria Doty Hilde Mangold, previously Hilde Proescholdt, was a German embryologist and physiologist who became well known for research completed with Hans Spemann in the 1920s. As a graduate student, Mangold assisted Spemann and together they discovered and coined the term the "organizer." The organizer discovery was a crucial contribution to embryology that led to further understanding of the pattern of embryo differentiation of amphibians. 2011-05-09 4 Jul 2018 - 4:40:59am
HIP Randomized Breast Cancer Screening Trial (1963–1982) Dina A. Lienhard From 1963 to 1982, researchers in New York City, New York, carried out a randomized trial of mammography screening. Mammography is the use of X-ray technology to find breast cancer at early stages. The private insurance company Health Insurance Plan of Greater New York, or HIP, collaborated with researchers Sam Shapiro, Philip Strax, and Louis Venet on the trial. The researchers’ goal was to determine whether mammography screening reduced breast cancer mortality in women. The study included sixty thousand women aged forty to sixty-four. 2017-08-08 15 Jan 2019 - 1:44:19am
Hodgson v. Minnesota (1990) Rainey Horwitz In the 1990 case Hodgson v. Minnesota, the US Supreme Court in Washington, D.C., upheld Minnesota statute 144.343, which required physicians to notify both biological parents of minors seeking abortions forty-eight hours prior to each procedure. The US Supreme Court determined that a state could legally require physicians to notify both parents of minors prior to performing abortions as long as they allowed for a judicial bypass procedure, in which courts could grant exceptions. The Supreme Court’s decision in Hodgson v. 2017-10-24 4 Jul 2018 - 4:40:59am
Homeobox Genes and the Homeobox Brad Jacobson Homeobox genes are a cluster of regulatory genes that are spatially and temporally expressed during early embryological development. They are interesting from both a developmental and evolutionary perspective since their sequences are highly conserved and shared across an enormously wide array of living taxa. 2010-10-11 4 Jul 2018 - 4:40:59am
Homunculus Cera R. Lawrence The term homunculus is Latin for "little man." It is used in neurology today to describe the map in the brain of sensory neurons in each part of the body (the somatosensory homunculus). An early use of the word was in the 1572 work by Paracelsus regarding forays into alchemy, De Natura Rerum, in which he gave instructions in how to create an infant human without fertilization or gestation in the womb. In the history of embryology, the homunculus was part of the Enlightenment-era theory of generation called preformationism. 2008-08-13 4 Jul 2018 - 4:40:59am
Hormone Releasing Intrauterine Devices Victoria Higginbotham Hormone releasing intrauterine devices or hormonal IUDs are contraceptive devices placed in a woman’s uterus to prevent pregnancy by continuously releasing a low dose of certain hormones. Jouri Valter Tapani Luukkainen, a medical researcher at the University of Helsinki, introduced the first hormonal IUD in 1976. Luukkainen’s IUD was a plastic device shaped like a capital T. 2019-06-03 5 Jun 2019 - 1:15:30am
Howard Wilber Jones Jr. Mark Zhang Howard Wilber Jones Jr. and his wife, Georgeanna Seegar Jones, developed a method of in vitro fertilization and helped create the first baby in the US using that method. Though the first in vitro baby was born in England in 1978, Jones and his wife's contribution allowed for the birth of Elizabeth Carr on 28 December 1981. Jones, a gynecologist and an obstetrician, researched human reproduction for most of his life. 2013-03-03 4 Jul 2018 - 4:40:59am
Hox Genes and the Evolution of Vertebrate Axial Morphology Experiment (1995) Joe Brinkman In 1995, researchers Ann Burke, Craig Nelson, Bruce Morgan, and Cliff Tabin in the US studied the genes that regulate the construction of vertebra in developing chick and mouse embryos, they showed similar patterns of gene regulation across both species, and they concluded that those patterns were inherited from an ancestor common to all vertebrate animals. The group analyzed the head-to-tail (anterior-posterior) axial development of vertebrates, as the anterior-posterior axis showed variation between species over the course of evolutionary time. 2017-06-23 4 Jul 2018 - 4:40:58am
Human Betterment Foundation (1928-1942) Jill Briggs In 1928 Ezra Seymour Gosney founded the non-profit Human Betterment Foundation (HBF) in Pasadena, California to support the research and publication of the personal and social effects of eugenic sterilizations carried out in California. Led by director Gosney and secretary Paul Popenoe, the HBF collected data on thousands of individuals in California who had been involuntarily sterilized under a California state law enacted in 1909. The Foundation's assets were liquidated following Gosney's death in 1942. 2013-07-10 4 Jul 2018 - 4:40:59am
Human Embryonic Stem Cells Ke Wu Stem cells are undifferentiated cells that are capable of dividing for long periods of time and can give rise to specialized cells under particular conditions. Embryonic stem cells are a particular type of stem cell derived from embryos. According to US National Institutes of Health (NIH), in humans, the term "embryo" applies to a fertilized egg from the beginning of division up to the end of the eighth week of gestation, when the embryo becomes a fetus. Between fertilization and the eighth week of gestation, the embryo undergoes multiple cell divisions. 2010-09-13 4 Jul 2018 - 4:40:59am
Human Evolution Inferred from Tooth Growth and Development Kate MacCord To study human evolution, researchers sometimes use microstructures found in human teeth and their knowledge of the processes by which those structures grow. Human fetusus begin to develop teeth in utero. As teeth grow, they form a hard outer substance, called enamel, through a process called amelogenesis. During amelogenesis, incremental layers of enamel form in a Circadian rhythm. This rhythmic deposition leaves the enamel with microstructures, called cross-striations and striae of Retzius, which have a regular periodicity. 2013-03-28 4 Jul 2018 - 4:40:59am
Human Fertilisation and Embryology Act (1990) Jonathan LaTourelle The Human Fertilisation and Embryology Act 1990 established the legal framework that governs infertility treatment, medical services ancillary to infertility treatment such as embryo storage, and all human embryological research performed in the UK. The law also defines a legal concept of the parent of a child conceived with assisted reproductive technologies. 2014-12-19 4 Jul 2018 - 4:40:59am
Human Fertilisation and Embryology Authority (1991- ) Sarah Taddeo In 1991, the United Kingdom established the Human Fertilisation and Embryology Authority (HFEA) as a response to technologies that used human embryos. The HFEA is a regulatory power of the Health and Social Services Department in London, UK, that oversees the implementation of reproductive technologies and the use of embryos in research within the United Kingdom. It establishes protocols by which researchers may use human embryos, develops legislation on how human embryos are stored and 2014-10-30 4 Jul 2018 - 4:40:59am
Human Papillomavirus (HPV) Strains 16 and 18 Grace Kim The Human Papillomavirus (HPV) strains 16 and 18 are the two most common HPV strains that lead to cases of genital cancer. HPV is the most commonly sexually transmitted disease, resulting in more than fourteen million cases per year in the United States alone. When left untreated, HPV leads to high risks of cervical, vaginal, vulvar, anal, and penile cancers. In 1983 and 1984 in Germany, physician Harald zur Hausen found that two HPV strains, HPV-16 and HPV-18, caused cervical cancer in women. In the early twenty first century, pharmaceutical companies Merck & Co. 2017-05-04 4 Jul 2018 - 4:40:59am

Humanae Vitae (1968), by Pope Paul VI Katherine Brind'Amour, Benjamin Garcia The "Humanae Vitae," meaning "Of Human Life" and subtitled "On the Regulation of Birth," was an encyclical promulgated in Rome, Italy, on 25 July 1968 by Pope Paul VI. This encyclical defended and reiterated the Roman Catholic Church's stance on family planning and reproductive issues such as abortion, sterilization, and contraception. The document continues to have a controversial reputation today, as its statements regarding birth control strike many Catholics as unreasonable. 2007-11-13 4 Jul 2018 - 4:40:59am
Hwang Woo-suk's Use of Human Eggs for Research 2002-2005 Anne Safiya Clay Hwang Woo-suk, a geneticist in South Korea, claimed in Science magazine in 2004 and 2005 that he and a team of researchers had for the first time cloned a human embryo and that they had derived eleven stem cell lines from it. Hwang was a professor at Seoul National University in Seoul, South Korea. In the Science articles, Hwang stated that all of the women who donated eggs to his laboratory were volunteers who donated their eggs (oocytes) without receiving any compensation in return. In 2006, Hwang admitted that many of the results were fabricated. 2014-08-12 4 Jul 2018 - 4:40:59am
Hydrocephalus During Infancy Alexandra Bohnenberger Hydrocephalus is a congenital or acquired disorder characterized by the abnormal accumulation of cerebrospinal fluid within the cavities of the brain, called ventricles. The accumulation of cerebrospinal fluid, the clear fluid surrounding the brain and spinal cord, causes an abnormal widening of the ventricles. The widening creates potentially harmful pressure on the tissues of the brain that can result in brain damage or death. 2017-03-07 4 Jul 2018 - 4:40:59am
Hypertensive Disorders in Pregnancy (1978), by Leon Chesley Sarah Patel Leon Chesley published Hypertensive Disorders in Pregnancy in 1978 to outline major and common complications that occur during pregnancy and manifest in abnormally high blood pressures in pregnant women. The book was published by Appleton-Century-Crofts in New York, New York. Chesley compiled his book as a tool for practicing obstetricians and teachers. 2017-04-27 4 Jul 2018 - 4:40:59am
Hysterectomy Kristin Kelley A hysterectomy is the surgical removal of a woman's uterus. For many women, a hysterectomy comes as a solution to health problems as diverse as abnormal bleeding to reproductive cancers. First performed in the early 1800s, this procedure has evolved in terms of both technique and popularity. The first successful abdominal hysterectomy was performed by Ellis Burnham in Lowell, Massachusetts, in 1853, although earlier attempts were made in the 1840s. 2010-09-02 4 Jul 2018 - 4:40:59am
Ian Donald (1910–1987) Nicole Erjavic Ian Donald was an obstetrician who developed the technology and therapy of ultrasound diagnostics during the twentieth century in Europe. Ultrasound is a medical diagnostic technique that uses sound waves to produce images of the inside of the body. During the early 1900s, physicians had no way to see inside a woman’s uterus during pregnancy. Donald developed the first method of scanning human internal anatomy in real time, which enabled doctors to diagnose potentially fatal tumors and cysts. 2018-01-30 4 Jul 2018 - 4:40:59am
Ian Wilmut (1944- ) Inbar Maayan British embryologist Sir Ian Wilmut, best known for his work in the field of animal genetic engineering and the successful cloning of sheep, was born 7 July 1944 in Hampton Lucy, England. The family later moved to Scarborough, in the north of the country, to allow his father to accept a teaching position. There Wilmut met Gordon Whalley, head of the biology department at Scarborough High School for Boys, which Wilmut attended. 2010-11-17 4 Jul 2018 - 4:40:59am
Ignacio Vives Ponseti (1914-2009) Katherine Gandee Ignacio Vives Ponseti developed a noninvasive method for treating congenital club foot in the US during the late 1940s. Congenital club foot is a birth deformity in which one or both of an infant's feet are rotated inward beneath the ankle, making normal movement rigid and painful. Ponseti developed a treatment method, later called the Ponseti method, that consisted of a series of manipulations and castings of the club foot performed in the first few months of life. 2017-03-09 4 Jul 2018 - 4:40:59am
Ignaz Philipp Semmelweis (1818-1865) Safiya Shaikh, Daniella Caudle Ignaz Philipp Semmelweis demonstrated that the use of disinfectants could reduce the occurrence of puerperal fever in patients in nineteenth century Austria. Puerperal fever is a bacterial infection that can occur in the uterine tract of women after giving birth or undergoing an abortion. Semmelweis determined that puerperal fever is contagious and argued that the unhygienic practices of physicians, like examining patients after performing autopsies, caused the spread of puerperal fever. 2017-04-06 4 Jul 2018 - 4:40:59am
Ilya Ilyich Mechnikov (Elie Metchnikoff) (1845-1916) Valerie Racine Ilya Ilyich Mechnikov studied phagocytes, immune function, and starfish embryos in Europe during the late nineteenth and early twentieth centuries. Mechnikov adopted the French form of his name, Élie Metchnikoff, in the last twenty-five years of his life. In 1908, he won the Nobel Prize in Physiology or Medicine with Paul Ehrlich for their contributions to immunology. Mechnikov discovered phagocytes, immune cells that protect organisms by ingesting foreign particles or microorganisms, by conducting experiments on starfish larvae. 2014-07-05 4 Jul 2018 - 4:40:59am
Images of Embryos in Life Magazine in the 1950s Olivia Conley Embryonic images displayed in Life magazine during the mid-twentieth century serve as a representation of technological advances and the growing public interest in the stages of embryological development. These black-and-white photographs portray skeletal structures and intact bodies of chicken embryos and human embryos and fetuses obtained from collections belonging to universities and medical institutions. 2010-06-30 4 Jul 2018 - 4:40:59am
In re Agent Orange Product Liability Litigation (1979-1984) Alexis Abboud In the legal case In re Agent Orange Product Liability Litigation of the early 1980s, US military veterans of the Vietnam War sued the US chemical companies that had produced the herbicide Agent Orange, and those companies settled with US veterans out of court. Agent Orange contains dioxin, a chemical later shown to disrupt the hormone system of the body and to cause cancer. As veterans returned to the US from Vietnam, scientists further confirmed that exposure to Agent Orange caused a variety of cancers in veterans and developmental problems in the veterans' children. 2017-04-10 4 Jul 2018 - 4:40:59am
In re Marriage of Witten (2003) In re Marriage of Witten, decided by the Iowa Supreme Court in 2003, held that neither Tamera nor Arthur (Trip) Witten could use or destroy several cryopreserved preembryos created during their marriage using in vitro fertilization (IVF), unless the former couple could reach a mutual agreement. Tamera and Trip Witten, unable to conceive conventionally during their marriage, had attempted to start a family together using IVF at the University of Nebraska Medical Center (UNMC) in Omaha, Nebraska. 2014-01-22 4 Jul 2018 - 4:40:59am
In the Matter of the Marriage of Dahl and Angle (2008) Jennifer E. Chapman, Mark Zhang In the 2008 court case In the Matter of the Marriage of Dahl and Angle, the Court of Appeals of Oregon upheld a written in vitro fertilization (IVF) consent form signed by Laura and Darrell Angle, who had each contributed their genetic material to the creation of several preembryos during their marriage. Its decision followed the general framework for resolving such disputes provided by the Supreme Court of Tennessee in Davis v. Davis in 1992, which was subsequently followed by many courts across the US. 2014-05-06 4 Jul 2018 - 4:40:59am
In the Womb (2005), by Toby Mcdonald and National Geographic Channel Inbar Maayan Written, produced, and directed by Toby Mcdonald, the 2005 National Geographic Channel film In the Womb uses the most recent technology to provide an intricate glimpse into the prenatal world. The technologies used, which include advanced photography, computer graphics, and 4-D ultrasound imaging, help to realistically illustrate the process of development and to answer questions about the rarely seen development of a human being. 2010-11-20 4 Jul 2018 - 4:40:59am
In the Womb: Identical Twins (2009), by National Geographic Maggie Pingolt National Geographic's documentary In the Womb: Identical Twins focuses on the prenatal development of human identical twins. Director Lorne Townend uses three-dimensional (3D) and four-dimensional (4D) ultrasound imaging and microscopy to depict twin development , genetic and epigenetic variations in the fetuses, and methods of fetal survival in the confines of the womb. Artist renditions of scientific data fill in areas of development inaccessible to the imaging tools. 2012-03-08 4 Jul 2018 - 4:40:59am
In Vitro Fertilization Tian Zhu In vitro fertilization (IVF) is an assisted reproductive technology (ART) initially introduced by Patrick Steptoe and Robert Edwards in the 1970s to treat female infertility caused by damaged or blocked fallopian tubes. This major breakthrough in embryo research has provided large numbers of women the possibility of becoming pregnant, and subsequent advances have dramatically increased their chances. IVF is a laboratory procedure in which sperm and egg are fertilized outside the body; the term "in vitro" is Latin for "in glass." 2009-07-22 4 Jul 2018 - 4:40:59am
Induced Pluripotent Stem Cell Experiments by Kazutoshi Takahashi and Shinya Yamanaka in 2006 and 2007 Zane Bartlett In 2006, Kazutoshi Takahashi and Shinya Yamanaka reprogrammed mice fibroblast cells, which can produce only other fibroblast cells, to become pluripotent stem cells, which have the capacity to produce many different types of cells. Takahashi and Yamanaka also experimented with human cell cultures in 2007. Each worked at Kyoto University in Kyoto, Japan. They called the pluripotent stem cells that they produced induced pluripotent stem cells (iPSCs) because they had induced the adult cells, called differentiated cells, to become pluripotent stem cells through genetic manipulation. 2015-06-01 4 Jul 2018 - 4:40:59am
Induced Pluripotent Stem Cells Katherine Brind'Amour Induced Pluripotent Stem Cells (iPSCs) are cells derived from non-pluripotent cells, such as adult somatic cells, that are genetically manipulated so as to return to an undifferentiated, pluripotent state. Research on iPSCs, initiated by Shinya Yamanaka in 2006 and extended by James Thompson in 2007, has so far revealed the same properties as embryonic stem cells (ESCs), making their discovery potentially very beneficial for scientists and ethicists alike. 2010-05-06 4 Jul 2018 - 4:40:59am
Inducing Fertilization and Development in Sand Dollars Karen Wellner Sand dollars are common marine invertebrates in the phylum Echinodermata and share the same class (Echinoidea) as sea urchins. They have served as model laboratory organisms for such embryologists as Frank Rattray Lillie and Ernest Everett Just. Both Lillie and Just used Echinarachnius parma for their studies of egg cell membranes and embryo development at the Marine Biological Laboratory (MBL) at Woods Hole, Massachusetts, in the early 1900s. 2010-06-24 4 Jul 2018 - 4:40:59am
Infant Mortality: Results of a Field Study in Johnstown, PA., Based on Births in One Calendar Year (1915), by Emma Duke Katherine Madgett The book Infant Mortality: Results of a Field Study in Johnstown, PA., Based on Births in One Calendar Year (1915), written by Emma Duke, detailed one of the first infant mortality field studies conducted by the US Children's Bureau. In the study, Duke and her colleagues collected information about over one thousand infants in the city of Johnstown, Pennsylvania. They used that information, along with interviews conducted with the families of the infants, to identify factors that affected infant mortality rates in the community. 2017-03-23 4 Jul 2018 - 4:40:59am
Infantile Autism: The Syndrome and Its Implications for a Neural Theory of Behavior (1964), by Bernard Rimland Sean Cohmer Infantile Autism: The Syndrome and Its Implications for a Neural Theory of Behavior (hereafter Infantile Autism) is a book written by Bernard Rimland, published in 1964. The book proposed a theory to explain the causes of autism. The book also synthesized research into autism and used Rimland's neural theory, described in the book, as a theory to explain some aspects of behavior, intelligence, and abnormality. 2014-05-23 4 Jul 2018 - 4:40:59am
Interspecies SCNT-derived Humanesque Blastocysts Sarah Taddeo, Jason S. Robert, Nicole Diehnelt Since the 1950s, scientists have developed interspecies blastocysts in laboratory settings, but not until the 1990s did proposals emerge to engineer interspecies blastocysts that contained human genetic or cellular material. Even if these embryos were not permitted to mature to fetal stages, their ethical and political status became debated within nations attempting to use them for research. 2017-06-23 4 Jul 2018 - 4:40:58am
Intracytoplasmic Sperm Injection Tian Zhu Intracytoplasmic Sperm Injection (ICSI) is an assisted reproductive technique (ART) initially developed by Dr. Gianpiero D. Palermo in 1993 to treat male infertility. It is most commonly used in conjunction with in vitro fertilization (IVF) or a less commonly used technique called zygote intrafallopian transfer (ZIFT). In natural fertilization, the sperm must penetrate the surface of the female egg, or oocyte. 2009-06-10 4 Jul 2018 - 4:40:59am
Intraspecies Chimeras Produced in Laboratory Settings (1960-1975) Sarah Taddeo When cells-but not DNA-from two or more genetically distinct individuals combine to form a new individual, the result is called a chimera. Though chimeras occasionally occur in nature, scientists have produced chimeras in a laboratory setting since the 1960s. During the creation of a chimera, the DNA molecules do not exchange genetic material (recombine), unlike in sexual reproduction or in hybrid organisms, which result from genetic material exchanged between two different species. A chimera instead contains discrete cell populations with two unique sets of parental genes. 2014-11-25 4 Jul 2018 - 4:40:59am
Intrauterine Insemination Tian Zhu Intrauterine insemination (IUI), also known as artificial insemination, is one of the earliest and simplest assisted reproductive technologies (ART). With this technique, sperm from either a partner or donor (such as from a sperm bank) is inserted with a syringe into the woman's vagina during ovulation to increase the probability that fertilization will occur and lead to pregnancy. 2009-07-22 4 Jul 2018 - 4:40:59am
Intrauterine Pressure Catheter Olivia Mandile An intrauterine pressure catheter (IUPC) is a device placed inside a pregnant woman’s uterus to monitor uterine contractions during labor. During labor, a woman’s uterus contracts to dilate, or open, the cervix and push the fetus into the birth canal. The catheter measures the pressure within the amniotic space during contractions and allows physicians to evaluate the strength, frequency, and duration of contractions. 2017-07-18 15 Jan 2019 - 2:28:51am
Irving Freiler Stein Sr. (1887–1976) Alexis Darby Irving Freiler Stein Sr. was a physician who studied women’s reproductive health during the twentieth century in the United States. In partnership with his colleague, Michael Leventhal, Stein identified a women’s reproductive disorder related to elevated male sex hormones, or androgens. The syndrome was originally called Stein-Leventhal syndrome and later known as polycystic ovarian syndrome. While studying the syndrome, Stein also helped establish a treatment for the condition, through the surgical removal of ovarian tissues. 2017-07-20 4 Jul 2018 - 4:40:59am
Isaacson v. Horne (2013) Claudia Nunez-Eddy In the 2013 case Isaacson v. Horne, the US Court of Appeals in the Ninth Circuit ruled that Arizona House Bill (HB) 2036, which prohibited abortions after twenty weeks of gestation, was unconstitutional. The Arizona State Legislature passed the law in 2012, which was then challenged by three physicians who filed a lawsuit against the state, arguing that the law violated women's constitutionally protected rights to abortions, rights that may only be infringed once fetuses are viable outside of the womb. 2016-11-16 15 Jan 2019 - 2:27:38am
Isidore Geoffroy Saint-Hilaire (1805-1861) Jesse Potestas Isidore Geoffroy Saint-Hilaire studied anatomy and congenital abnormalities in humans and other animals in nineteenth century France. Under the tutelage of his father, Etienne Geoffroy Saint-Hilaire, Isidore compiled and built on his father's studies of individuals with developmental malformations, then called monstrosities. 2017-02-11 4 Jul 2018 - 4:40:59am
Isotretinoin (Accutane) as a Teratogen Chanapa Tantibanchachai Isotretinoin is a molecule and a byproduct (metabolite) of vitamin A, and in greater than normal amounts in pregnant women, it can cause fetal abnormalities including cleft lips, ear and eye defects, and mental retardation. Isotretinoin is commonly called by its trade name Accutane, and it's a chemical compound derived from vitamin A, or retinoic acid. Doctors prescribe isotretinoin to treat severe acne. For pregnant women, too much vitamin A or isotretinoin can also cause greater than normal rates of stillbirths and fetal disintegrations after the ninth week of gestation. 2014-07-20 4 Jul 2018 - 4:40:59am
J. B. v. M. B. (2001) Jennifer E. Chapman In 2001, the Supreme Court of New Jersey decided a dispute between a divorced couple over cryopreserved preembryos created through in vitro fertilization (IVF) during the coupleÕs marriage. The former wife (J.B.) wanted the preembryos destroyed, while her former husband (M.B.) wanted them to be used for future implantation attempts, such as by an infertile couple. In J.B. v. M.B. (2001), the court declined to force J.B. to become a parent against her will, concluding that doing so would violate state public policy. 2013-11-17 4 Jul 2018 - 4:40:59am
J.B. v. M.B. [Brief] (2001) Brock Heathcotte In a dispute over frozen embryos during a divorce case, the court decided the wife's fundamental right to not procreate mandated destruction of the pre-embryos in light of the husband's continuing ability to procreate with a different partner. The court also said embryo disposition agreements used by in vitro fertilization clinics were generally enforceable subject to either spouse's right to change his or her mind prior to use of the pre-embryos. 2008-05-09 4 Jul 2018 - 4:40:59am
