Book excerpt: Starting in 1978, when the first babies conceived through in vitro fertilization (IVF) were born in the UK and India, assisted reproduction has become a global industry. Contributors to this edited collection reflect on the global dimensions of IVF and assisted reproductive technologies, examining how people have used these technologies to create diverse family forms, including gay, lesbian, and transgender parenthood, as well as complex configurations of genetic, gestational, and social parenthood. The authors examine how IVF and other reproductive technologies have and have not circulated around the globe; how reproductive technologies can be situated historically, nationally, locally, and culturally; and the ways in which culture, practices, regulations, norms, families, and kinship ties may be reinforced or challenged through the use of assisted reproduction.
