Preimplantation genetic testing for sickle cell disease: a cost-effectiveness analysis.

Objective: To evaluate the cost-effectiveness of in vitro fertilization with preimplantation genetic testing for monogenic disease (IVF + PGT-M) in the conception of a nonsickle cell disease (non-SCD) individual compared with standard of care treatment for a naturally conceived, sickle cell disease (SCD)-affected individual.

Design: A Markov simulation model was constructed to evaluate a one-time IVF + PGT-M treatment compared with the lifetime standard of care costs of treatment for an individual potentially born with SCD. Using an annual discount rate of 3% for cost and outcome measures, quality-adjusted life years were constructed from utility weights and life expectancy values and then used as the effectiveness measurement.

P450 Side-Chain Cleavage Enzyme (P450-SCC) Is an Ovarian Autoantigen in a Mouse Model for Autoimmune Oophoritis.

Steroid-producing cells contain key cytochrome P450 enzymes, such as side-chain cleavage (P450-SCC) and 17α-hydroxylase (17α-OH). They are required for steroid hormone synthesis and considered antigens associated with Addison's disease and autoimmune primary ovarian insufficiency (POI). We studied an animal model for human autoimmune POI in mice with autoimmune oophoritis induced by neonatal thymectomy performed at day 3 (TX3).

Preconception hemoglobin A1c concentration in healthy women is not associated with fecundability or pregnancy loss.

Objective: To examine the relationship of preconception hemoglobin A1c, a marker of cumulative exposure to glucose over the preceding 2-3 months, with time to pregnancy, pregnancy loss, and live birth among fecund women without diagnosed diabetes or other medical diseases.

Design: A secondary analysis of a prospective cohort of women participating in the Effects of Aspirin in Gestation and Reproduction (EAGeR) trial.

Setting: Four US academic medical centers.

Karyotypic abnormalities and Y chromosome microdeletions: How do these impact in vitro fertilization outcomes, and how common are they in the modern in vitro fertilization practice?

Objective: To examine the outcomes of in vitro fertilization with intracytoplasmic sperm injection (IVF-ICSI) in couples in whom the male partner has a karyotypic abnormality or Y chromosome microdeletion (YCM).

Design: Retrospective cohort.

Setting: Single infertility center.

Creating an Artificial 3-Dimensional Ovarian Follicle Culture System Using a Microfluidic System.

We hypothesized that the creation of a 3-dimensional ovarian follicle, with embedded granulosa and theca cells, would better mimic the environment necessary to support early oocytes, both structurally and hormonally. Using a microfluidic system with controlled flow rates, 3-dimensional two-layer (core and shell) capsules were created. The core consists of murine granulosa cells in 0.

Menstrual Dysfunction in PCOS.

Menstrual irregularities due to anovulation or severe oligoovulation are a key feature of polycystic ovary syndrome for many women. First-line intervention should entail dietary and lifestyle modifications for overweight or obese polycystic ovary syndrome women. For women not seeking fertility, combination low-dose hormonal contraception are the most effective and first-line choice for regulating menstrual cycles.

Lifestyle Modifications in PCOS.

Lifestyle modification is widely considered to be the cornerstone of polycystic ovary syndrome (PCOS) treatment. However, 45% of women with PCOS have reported that they have never been provided information about lifestyle management. This highlights a significant gap in knowledge and is reflective of the lack of evidence-based guidance for lifestyle modification.

Polycystic Ovarian Syndrome Genetics and Epigenetics.

Polycystic ovarian syndrome and its associated endocrine abnormalities comprise one of the most common metabolic spectrum disorders within the human race. Because of the variance in phenotypic expression among individuals and within family lineages, attention has been turned to genetic and epigenetic changes in which the root cause of the disorder may lie. Further understanding of DNA/histone methylation and microRNA patterns may help to improve the accuracy of diagnosis and lead to future treatment options.

Circulating Vascular Endothelial Growth Factor and Soluble fms-Like Tyrosine Kinase-1 as Biomarkers for Endometrial Remodeling Across the Menstrual Cycle.

Objective: To characterize variation in circulating vascular endothelial growth factor (VEGF) and its receptor, soluble fms-like tyrosine kinase-1 (sFLT-1), across the menstrual cycle in normal ovulating women in relation to reproductive hormones to identify the utility of VEGF and sFLT-1 as peripheral biomarkers of endometrial remodeling.

Methods: Ninety-six healthy, regularly menstruating ovulatory women, aged 18-44 years, enrolled in the BioCycle Study, a prospective cohort study at a U.S.

Does ovarian stimulation benefit ovulatory women undergoing therapeutic donor insemination?

Objective: To compare clinical and ongoing pregnancy after natural cycle (NC) intrauterine insemination (IUI) versus ovarian stimulation (OS) IUI in ovulatory women undergoing therapeutic donor insemination (TDI).

Design: Retrospective cohort.

Setting: Single infertility center.

The Safety of Low-Dose Aspirin on the Mode of Delivery: Secondary Analysis of the Effect of Aspirin in Gestation and Reproduction Randomized Controlled Trial.

Objective: This study aimed to examine whether prenatal low-dose aspirin (LDA) therapy affects risk of cesarean versus vaginal delivery.

Study Design: This study is a secondary analysis of the randomized clinical effects of aspirin in gestation and reproduction (EAGeR) trial. Women received 81-mg daily aspirin or placebo from preconception to 36 weeks of gestation.

Altered evolution: are reproductive endocrinology and infertility specialists ready for the genetically engineered future?

Science, propelled forward by noble aspirations and, at times, human hubris, has the capacity to affect lives and alter the world in unanticipated ways. Even seemingly minor discoveries have repeatedly proven to have far reaching implications that experts within their respective fields could not have predicted. Nuclear technology is both a source of energy and a potential means of annihilation.

Endometriosis does not impact live-birth rates in frozen embryo transfers of euploid blastocysts.

Objective: To determine whether subfertility in patients with endometriosis is due to impaired endometrial receptivity by comparing pregnancy and live-birth outcomes in women with endometriosis versus two control groups without suspected endometrial factors: noninfertile patients who underwent assisted reproduction to test embryos for a single-gene disorder and couples with isolated male factor infertility.

Design: Retrospective cohort.

Setting: Multicenter private practice.

Recalled maternal lifestyle behaviors associated with anti-müllerian hormone of adult female offspring.

Anti-müllerian hormone (AMH) is an established marker of ovarian reserve that decreases with age. Though the pool of ovarian follicles is established during fetal development, impacts of in utero exposures on AMH are uncertain. Thus, we sought to evaluate associations of in utero exposures with AMH of adult daughters with a prospective cohort study of adult daughters at university medical centers.

Low-dose aspirin in reproductive health: effects on menstrual cycle characteristics.

Objective: To estimate the effect of daily 81 mg low-dose aspirin (LDA) on menstrual cycle length and hormone profiles.

Design: Secondary analysis of a trial evaluating the effect of daily LDA or placebo on live birth among women with one or two previous pregnancy losses.

Setting: University medical centers.

Lesbian Women Undergoing Assisted Reproduction: Diverse, But Not Different.

The use of assisted reproduction among women in relationships with other women has increased in the United States over the past decade as a result of increased legal access and social acceptance. Despite this shift, limited studies currently exist to guide optimal fertility care for this growing patient population of women seeking assisted reproduction. In this Commentary, assisted reproduction will be meant to include ovulation induction, intrauterine insemination (IUI), and in vitro fertilization (IVF).

Polycystic Ovary Syndrome and Medical Conditions.

Polycystic ovary syndrome is a common endocrinopathy that has been associated with many medical conditions across nearly every specialty. This chapter reviews the current understanding of polycystic ovary syndrome and associated medical conditions.

Clinical Presentation and Diagnosis of Polycystic Ovarian Syndrome.

Polycystic ovarian syndrome (PCOS) is a common endocrinopathy with many clinical manifestations. The effects on women's lives start at puberty and can last throughout her lifetime. Women frequently experience anovulatory menstrual cycles, infertility, hirsutism, obesity and increased risk of diabetes mellitus, hypertension, lipid abnormalities, and metabolic syndrome.
