Impact of time interval from cesarean delivery to frozen embryo transfer on reproductive and neonatal outcomes.

Objective: To evaluate differences in reproductive and neonatal outcomes on the basis of the time interval from cesarean delivery to subsequent frozen embryo transfer (FET).

Design: Retrospective cohort.

Setting: Multicenter fertility practice.

Luteal phase support with progesterone does not improve pregnancy rates in patients undergoing ovarian stimulation with letrozole.

Research Question: Does luteal phase support with vaginal progesterone improve clinical pregnancy rates in patients undergoing ovarian stimulation with letrozole?

Design: This was a retrospective cohort study of patients undergoing ovarian stimulation with letrozole paired with intrauterine insemination (IUI) or timed intercourse (TIC) from January 2018 to October 2021. The primary outcome of clinical pregnancy rate (CPR) was calculated for cycles with and without luteal phase progesterone support. Univariate logistic regressions were done to evaluate predictor variables for CPR.

Loss of anti-Müllerian hormone (AMH) immunoactivity due to a homozygous AMH gene variant rs10417628 in a woman with classical polycystic ovary syndrome (PCOS).

Anti-Müllerian hormone (AMH) is produced by granulosa cells of pre-antral and small antral ovarian follicles. In polycystic ovary syndrome (PCOS), higher levels of serum AMH are usually encountered due to the ample presence of small antral follicles and a high AMH production per follicular unit which have led to the proposal of AMH as a serum diagnostic marker for PCOS or as a surrogate for polycystic ovarian morphology (PCOM). However, heterozygous coding mutations of the AMH gene with decreased in vitro bioactivity have been described in some women with PCOS.

Measures of Patient Dissatisfaction With Health Care in Polycystic Ovary Syndrome: Retrospective Analysis.

Background: Polycystic ovary syndrome (PCOS) is a common reproductive and metabolic disorder in women; however, many clinicians may not be well versed in scientific advances that aid understanding of the associated reproductive, metabolic, and psychological abnormalities. Women with PCOS are dissatisfied with health care providers, the diagnostic process, and the initial treatment of PCOS and seek information through alternative sources. This has affected the patient-physician relationship by allowing medical information acquired through the internet, whether correct or not, to become accessible to patients and reshape their health care perspective.

Euploid rates among oocyte donors: is there an optimal age for donation?

Purpose: To examine cycle blastocyst euploid rates among age subgroups of oocyte donors.

Methods: Retrospective cohort analysis of ova donation in vitro fertilization cycles (OD-IVF) for which trophectoderm biopsy for preimplantation genetic testing for aneuploidy (PGT-A) by array comparative genomic hybridization (aCGH) or next generation gene sequencing (NGS) was employed between January 2015 and December 2018 in a single high-volume fertility center.

Results: Compared to oocyte donors age 26-30, oocyte donors age ≤ 25 had similar cycle blastocyst euploid rates (80 [66.

Risk factors for cervical ectopic pregnancy.

Objective: To evaluate risk factors for cervical ectopic pregnancies.

Methods: Retrospective, quasi-experimental case-control study of cervical ectopic pregnancy (CEP) cases from 2000-2013. Two groups were selected as controls, patients with tubal ectopic (TEP) and intrauterine pregnancies (IUP) without a history of TEP, matched by year of pregnancy and randomly sampled in a 1:3 case-control ratio per each study group.

Mechanisms of intergenerational transmission of polycystic ovary syndrome.

Developmental origins of adult disease (DoHAD) refers to critical gestational ages during human fetal development and beyond when the endocrine metabolic status of the mother can permanently program the physiology and/or morphology of the fetus, modifying its susceptibility to disease after birth. The aim of this review is to address how DoHAD plays an important role in the phenotypic expression of polycystic ovary syndrome (PCOS), the most common endocrinopathy of women characterized by hyperandrogenism, oligo-anovulation and polycystic ovarian morphology. Clinical studies of PCOS women are integrated with findings from relevant animal models to show how intergenerational transmission of these central components of PCOS are programmed through an altered maternal endocrine-metabolic environment that adversely affects the female fetus and long-term offspring health.

Primary ovarian insufficiency in an adolescent population: clinical phenotype and diagnostic approach.

Background Primary ovarian insufficiency (POI) can be seen in adolescents secondary to genetic or autoimmune conditions, or gonadotoxic therapies. Often times, its underlying cause is not identified. It is a rare condition in pediatrics, but a thorough evaluation is required for a timely diagnosis and optimizing outcomes.

Adipose Insulin Resistance in Normal-Weight Women With Polycystic Ovary Syndrome.

Context: Normal-weight women with polycystic ovary syndrome (PCOS) may have adipose tissue insulin resistance (adipose-IR).

Objective: To examine whether adipose-IR and subcutaneous (SC) abdominal adipose stem cell (ASC) gene expression are altered in normal-weight women with PCOS and correlated with hyperandrogenemia and/or whole-body IR.

Design: Prospective cohort study.

Outcomes in subsequent pregnancies after wedge resection for interstitial ectopic pregnancy: a retrospective cohort study.

Objective: The objective of this study is to evaluate pregnancy outcomes in patients with a history of wedge resection for interstitial ectopic pregnancy (WRIEP).

Methods: Retrospective cohort study of pregnancies with a history of WRIEP from 2000 to 2013 at two inner city hospitals in Detroit, MI. Pregnant-matched controls (1:3) were selected and included patients with history of surgically treated tubal ectopic pregnancy and delivered patients without history of ectopic pregnancy.

Endometriosis and Imaging.

Endometriosis is a condition with variable location, size, and lesion composition which poses a diagnostic imaging challenge for the practicing gynecologist. Transvaginal ultrasound and magnetic resonance imaging are the most frequent imaging techniques used for its evaluation, but transvaginal ultrasound should be the first-line approach, as it is often sufficient, followed by modified ultrasound techniques. Magnetic resonance imaging should be considered when a diagnosis has not been achieved by sonographic means or when the renal system needs to be concurrently evaluated.

Imaging in Endometriosis and Adenomyosis.

Endometriosis and adenomyosis may be accurately diagnosed using ultrasound (US). Several findings are characteristic and various US modalities have been described. Recent development of 3-dimensional transvaginal US has resulted in a major advance in the evaluation of adenomyosis.

Fragile X premutation in women: recognizing the health challenges beyond primary ovarian insufficiency.

Fragile X premutation carriers have 55-200 CGG repeats in the 5' untranslated region of the FMR1 gene. Women with this premutation face many physical and emotional challenges in their life. Approximately 20% of these women will develop fragile X-associated primary ovarian insufficiency (FXPOI).

Differences in clinical presentation and pregnancy outcomes in antepartum preeclampsia and new-onset postpartum preeclampsia: Are these the same disorder?

Objective: New-onset postpartum preeclampsia is a poorly defined condition that accounts for a significant percentage of eclampsia cases. It is unclear whether new-onset postpartum preeclampsia is a different disorder from or belongs to the same spectrum of classic antepartum preeclampsia. The objective of this study was to compare the clinical presentation and pregnancy outcomes of antepartum preeclampsia and new-onset postpartum preeclampsia.

Morbid obesity and outcome of ectopic pregnancy following capped single-dose regimen methotrexate.

Purpose: Evaluate whether morbid obesity influenced resolution, number of doses or ultimately surgical management of tubal ectopic pregnancy (TEP) when treated with single-dose regimen methotrexate (SDR-MTX) capped at 100 mg.

Methods: Retrospective cohort study of patients with a diagnosis of TEP who underwent MTX treatment from 2000 to 2013. Patients were excluded if initial β-hCG <1000 mIU/mL, did not have β-hCG follow-up or were not treated with SDR-MTX.
