EXPOSURE Undergoing IVF MAIN OUTCOME

OBJECTIVE To study genital response and sexual arousal in women with and without PCOS and to assess associations with sex steroid levels. DESIGN This observational prospective case control study was conducted from March 2017 until March 2020. SUBJECTS Heterosexual women with (n=68) and without PCOS (n=67), aged 18-40 years, in a steady relationship and without any comorbidities. EXPOSURE All participants

OBJECTIVE To investigate if blastocysts originating from different follicular cohorts have variable implantation rates, adjusted for oocyte age, morphology and/or ploidy DESIGN: Retrospective cohort SETTING: Academic center SUBJECTS: Patients who underwent one or more cycles of autologous ovarian stimulation and in vitro fertilization/intracytoplasmic sperm injection, followed by elective single frozen

OBJECTIVE We examined if thyroid autoimmunity is relevant to the relationship between maternal TSH levels and pregnancy outcomes. DESIGN Retrospective cohort analysis of data from two randomized controlled trials (RCTs). SUBJECTS Participants of the Pregnancy in Polycystic Ovary Syndrome (PPCOS II, n = 746) and the Assessment of Multiple Intrauterine Gestations from Ovarian Stimulation (AMIGOS, n =

OBJECTIVE To evaluate whether perinatal and infant outcomes differ between singleton births following assisted reproductive technology (ART) in women with endometriosis alone and those with other causes of infertility. DESIGN Population-based data linkage cohort study. SUBJECTS A total of 29,152 ART-conceived singleton births from 24,116 mothers, 2010-2017, New South Wales, Australia. EXPOSURE Endometriosis

IMPORTANCE During FET cycles in IVF/ICSI patients (including PGT patients), transfer of embryos that have been thawed may be abandoned for medical or personal reasons, resulting in the need to refreeze embryos. Typically, embryos from patients undergoing preimplantation genetic testing (PGT) are cryopreserved after biopsy, pending test results. However, in the absence of a clear result, another biopsy

OBJECTIVE To evaluate whether preimplantation genetic testing for aneuploidy (PGT-A) benefits women of advanced reproductive age (≥38 years old) with a diminished ovarian reserve (DOR; not more than three retrieved oocytes). DESIGN A retrospective analysis comparing two groups: (a) PGT-A group: women who chose PGT-A and subsequent single re-warmed embryo transfers (ETs) and (b) non-PGT-A group: women

OBJECTIVE To determine the impact of oral contraceptive (OC) induced mood lability/depression on treatment maintenance in women with endometriosis. DESIGN Women with endometriosis were retrospectively identified through International Classification of Diseases-10 codes and then a comprehensive electronic medical record review was conducted, identifying mood lability/depression as a reason for treatment

OBJECTIVE To investigate associations between assisted reproductive technology (ART) -induced alterations in corpus luteum (CL) number during implantation, and maternal pregnancy and birth outcomes. Pregnancies conceived through ART are associated with increased risks of adverse obstetric and perinatal outcomes, with discrepancies in outcomes between different ART treatment protocols. We hypothesize

OBJECTIVE To determine the serum anti-Müllerian-hormone (AMH) and antral follicle count (AFC) thresholds indicating an increased risk of hyper-response to ovarian stimulation (OS) during in-vitro-fertilization (IVF), as defined by the HERA (Hyper-response Risk Assessment) Delphi Consensus. DESIGN A retrospective multicenter cohort study. SUBJECTS Included were women with normal ovarian reserve markers

Capsule: The most frequent inherited bleeding disorder, von Willebrand disease, does not negatively affect reproductive outcomes in women undergoing fertility treatment as clinical pregnancy rates, pregnancy loss rates, and baby take-home rates were all similar to the control group.

To evaluate the effectiveness of the preoperative ultrasound-based endometriosis staging system (UBESS) in anticipating the complexity of laparoscopic surgery for optimal patient counseling and treatment.

To evaluate the safety and efficacy of prednisone on pregnancy rates and semen concentrations at 1 year after vasectomy reversal.

OBJECTIVE To develop a consensus on histologic human ovarian follicle staging nomenclature, provide guidelines for follicle density calculation, and assess changes due to fixation to enhance communication among clinicians and ovarian biology researchers in order to gain a deeper understanding of human fertility. METHODS Beginning in March 2021, the Ovarian Nomenclature Workshop's Follicle Classification

To compare efficacy and safety of human chorionic gonadotropin (hCG), gonadotropin-releasing hormone (GnRH) agonist, dual, and double triggers in predicted healthy responders undergoing ovarian stimulation and in vitro fertilization.

Understanding the potential risks associated with fertility treatments (FTs) can guide clinical decision and patient counseling.

To determine whether translocation carriers have a reduced number of usable blastocysts compared with infertile controls.

To describe the technique of embryofetoscopy performed with 5Fr instruments with targeted evacuation of the gestational sac followed by a visual dilatation and curettage (D&C) using the hysteroscopic tissue removal system for the management of first trimester missed abortion in a patient with uterine septum.

Although childhood adversity has been extensively studied in relation to various health outcomes, investigation of its association with gynecological conditions remains limited.

To evaluate the efficacy and safety of the estetrol (E4) (15 mg)/drospirenone (DRSP) (3 mg) combination in a cyclic regimen in Japanese women with primary and secondary dysmenorrhea.

To study the value of hysteroscopic cytoreductive surgery for adenomyotic lesions to improve reproductive outcomes. We describe a feasible and novel minimal invasive stepwise approach, which did not result in postoperative adhesion formation and restored favorable reproductive outcomes.

To examine the association between sociodemographic factors and utilization of infertility services by race and ethnicity in a state with a comprehensive infertility mandate.

Aromatase inhibitors, particularly letrozole (LZ), are now established as first-line ovulation induction agents, offering an effective ovarian stimulation strategy to enhance outcomes of intrauterine insemination. In recent years, they have also emerged as potentially valuable adjuvants to gonadotropin ovarian stimulation for in vitro fertilization, particularly in fertility preservation in women with
