The reproductive donation families and their quality of parenting. A meta-analytic and systematic review

The reproductive donation families and their quality of parenting. A meta-analytic and systematic review

This review examined whether the absence of a genetic link with one or both parents in reproductive donation (RD) families induced a different quality of parenting from that found in families with spontaneous conception (SC) or with autologous assisted reproductive technology (AUT-ART), where the genetic mother carries out the pregnancy, and both parents have a genetic link with their children.MEDLINE, PSYCHINFO, and PUBMED were searched for English-language studies published from January 1993 through October 2021.

Findings from a mobile application–based cohort are consistent with established knowledge of the menstrual cycle, fertile window, and conception

Findings from a mobile application-based cohort are consistent with established knowledge of the menstrual cycle, fertile window, and conception

To investigate the validity of self-reported fertility data generated by a mobile application-based cohort in comparison with data collected by traditional clinical methodologies. Data were collected from July 2013 to July 2018 through a mobile application designed to track fertility. Bayesian hierarchical models were used to assess day-specific pregnancy probabilities.

Intramuscular progesterone optimizes live birth from programmed frozen embryo transfer: a randomized clinical trial

Intramuscular progesterone optimizes live birth from programmed frozen embryo transfer: a randomized clinical trial

To determine whether vaginal progesterone for programmed endometrial preparation is noninferior to intramuscular progesterone in terms of live birth rates from frozen embryo transfer (FET). Three-armed, randomized, controlled noninferiority trial. Multicenter fertility clinic. A total of 1,346 volunteer subjects planning vitrified-warmed transfer of high-quality nonbiopsied blastocysts were screened, of whom 1,125 subjects were ultimately enrolled and randomly assigned to treatment.
