Let's not abandon programmed frozen embryo transfers yet: a countercurrent perspective.

The countercurrent opinion given in this paper is that the optimal management of frozen embryo transfers (FET) is not a one-size-fits-all matter, but rather one that should be decided after considering all the various parameters and options. This choice should notably encompass patients' individual characteristics - including variable risks of obstetric complications - and weigh out the respective advantages of each FET option in each case. While there may be real advantages for natural-cycle FET in many cases, these need to be balanced against both practical and clinical issues.

Fertility workups: the times they are a-changin'.

The workup of patients seeking assisted reproductive technology (ART) treatments has been modified by the tremendous improvements in ART efficacy accomplished recently. Moreover, the fact that ART is nowadays also offered to women who are not necessarily infertile-seeking genetic testing of their embryos-lead to important changes in how we investigate ART candidates. All the facets of these changes have been reviewed in the present introduction to this View-and-Review series on modern-day infertility workups.

Trends and Outcomes for Preimplantation Genetic Testing in the United States, 2014-2018.

This study uses US national surveillance data to describe preimplantation genetic testing trends and outcomes between 2014 and 2018.

Predicting personalized cumulative live birth following in vitro fertilization.

Objective: To develop in vitro fertilization (IVF) prediction models to estimate the individualized chance of cumulative live birth at two time points: pretreatment (i.e., before starting the first complete cycle of IVF) and posttreatment (i.

Prior and novel coronaviruses, Coronavirus Disease 2019 (COVID-19), and human reproduction: what is known?

Objective: To summarize current understanding of the effects of novel and prior coronaviruses on human reproduction, specifically male and female gametes, and in pregnancy.

Design: Review of English publications in PubMed and Embase to April 6, 2020.

Method(s): Articles were screened for reports including coronavirus, reproduction, pathophysiology, and pregnancy.

Association of In Vitro Fertilization With Childhood Cancer in the United States.

Importance: In vitro fertilization (IVF) is associated with birth defects and imprinting disorders. Because these conditions are associated with an increased risk of childhood cancer, many of which originate in utero, descriptions of cancers among children conceived via IVF are imperative.

Objective: To compare the incidence of childhood cancers among children conceived in vitro with those conceived naturally.

National survey of the Society for Assisted Reproductive Technology membership regarding insurance coverage for assisted reproductive technologies.

Objective: To assess the attitudes of Society for Assisted Reproductive Technology (SART) members regarding expanding insurance coverage for patients seeking assisted reproductive technologies (ART) and identify some of the factors that may influence such attitudes.

Design: An anonymous online 14-question survey of SART membership; 1,556 surveys were sent through the SART Research Portal from June to December 2017. Questions were incremental in scope, beginning with expanding insurance coverage for ART for vulnerable populations (e.

Increased risk of large-for-gestational age birthweight in singleton siblings conceived with in vitro fertilization in frozen versus fresh cycles.

Background: Children born from fresh in vitro fertilization (IVF) cycles are at greater risk of being born smaller and earlier, even when limited to singletons; those born from frozen cycles have an increased risk of large-for-gestational age (LGA) birthweight (z-score ≥1.28). This analysis sought to overcome limitations in other studies by using pairs of siblings, and accounting for prior cycle outcomes, maternal characteristics, and embryo state and stage.

Society for Assisted Reproductive Technology and assisted reproductive technology in the United States: a 2016 update.

The Society for Assisted Reproductive Technology (SART) was established within a few years of assisted reproductive technology (ART) in the United States, and has not only reported on the evolution of infertility care, but also guided it toward improved success and safety. Moving beyond its initial role as a registry, SART has expanded its role to include quality assurance, data validation, practice and advertising guidelines, research, patient education and advocacy, and membership support. The success of ART in this country has greatly benefited from SART's role, as highlighted by a series of graphs.

British Society of Prosthodontics Debate on the Implications of the Minamata Convention on Mercury to Dental Amalgam--Should our Patients be Worried?

In 2013, the Minamata Convention on Mercury called for a global phase-down of amalgam use, with a view to reduce environmental mercury pollution. This will significantly impact UK dentistry, given the still extensive use of amalgam in U.K.

Why we may abandon basal follicle-stimulating hormone testing: a sea change in determining ovarian reserve using antimüllerian hormone.

Antimüllerian hormone is the most informative serum marker of ovarian reserve currently available and should be considered an important part of any contemporary reproductive medicine practice. It is both more convenient and informative than basal FSH and can be assessed at any point in the cycle. It is the most useful serum method of determining ovarian reserve, which guides pretreatment counseling, choice of infertility treatment, and avoidance of ovarian hyperstimulation.

Gonadotropin-releasing hormone agonist pretreatment did not decrease postoperative adhesion formation after abdominal myomectomy in a randomized control trial.

Objective: To determine if 3 months of preoperative gonadotropin-releasing hormone agonist (GnRH-a) treatment decreases postoperative uterine adhesions after open abdominal surgery for the removal of uterine fibroids.

Design: Prospective, randomized, clinical study.

Setting: A tertiary care medical center.

Follicle-stimulating hormone and estradiol levels independently predict the success of assisted reproductive technology treatment.

Objective: To evaluate the relationship between early follicular phase levels of FSH and E(2) and outcomes of therapy with assisted reproductive technologies (ART).

Design: Retrospective cohort study.

Setting: ART centers in the United States.

Modest follicle-stimulating hormone elevations in younger women: warn but don't disqualify.

Markers of quantitative defects in egg production (low ovarian reserve) have often been used to exclude patients from treatment, even when egg quality is apt to be satisfactory. Women younger than 38 years of age with modest FSH elevations (10-15 or even 20 IU/L) have acceptable pregnancy rates despite their limited production of eggs ("quality matters more than quantity") and so should be given the opportunity to try IVF.
