BACKGROUND Our study compares the efficacy of the combined contraceptive vaginal ring to oral contraceptive pills (OCPs) for hypothalamic-pituitary-ovarian (HPO) axis suppression in egg donor in vitro fertilization (IVF) cycles. METHODS Our retrospective cohort study includes patients from the Center for Assisted Reproduction (CARE) in Bedford, Texas undergoing IVF cycles as egg donors from J...

BACKGROUND This paper documents how couples and providers access donor materials for conception in the Indian context and perceptions about using them. The objective is to facilitate understanding of critical issues and relevant concerns. METHODS A postal survey was conducted with a sample of 6000 gynaecologists and in-depth interviews were -conducted with 39 gynaecologists in four cities. ...

As part of a larger study on donor-assisted conception, this paper reports research which explored the ways in which women who have donated or received eggs or embryos interpret such donations in the context of motherhood. Narrative analysis of women's accounts revealed that egg and embryo donations are not interpreted as incompatible with motherhood; that they may be explained as contributing ...

OBJECTIVE The aim of this study was to investigate the effect of sperm DNA fragmentation on fertilization rate, embryo development (blastulation rate), and pregnancy outcomes for ICSI cycles performed in a cohort of couples using donor eggs and to assess the remaining embryos that were not transferred or frozen for apoptotic markers. METHODS Eighty-two women (egg recipients) were included in ...

Abstract The development of vitrification techniques has increased the use donor ova by allowing for their cryopreservation, storage, and international transportation. However, implications egg banking valuation eggs remain little studied. Building on ethnographic fieldwork in a Ukrainian bank, this article I examine different mechanisms calculations that allow bank to transform vitrified ova—p...

wolbachia is an intracellular endosymbiont, which can induce thelytokous parthenogenesis in trichogramma egg parasitoids with the infected females producing daughters without any mating. with regard to the usual transfer of wolbachia which is vertical from the mother to her offspring through the cytoplasm of eggs, this manipulation of host’s reproduction can enhance its transmission to future g...

BACKGROUND Despite the meager role of the masculine agent in infertility (the low number of infertile men than women infertile), there are men whose wives are unable to become pregnant due to the absence of sperm, decreased numbers of sperm or lack of sufficient motile sperm. Utilizing donated sperm is a method that enables these families to have children. The use of this method prompts us to a...

The uterus is the reproductive organ where embryo formed by fertilization of sperm and egg settles continues its development until birth. With transition transplantation from experimental studies to clinical trials starting have babies in this way, offers a solution that can enable these women children genetically on their own grow them wombs. Uterine transplant procedure combines both assisted...

CONTEXT Mutations of the fragile X mental retardation 1 (FMR1) gene are associated with distinct ovarian aging patterns. OBJECTIVE To confirm in human in vitro fertilization (IVF) that FMR1 affects outcomes, and to determine whether this reflects differences in ovarian aging between FMR1 mutations, egg/embryo quality or an effect on implantation. DESIGN, SETTING, PATIENTS IVF outcomes were ...
