Intrauterine adhesion (IUA), also referred to as Asherman's syndrome, is characterized by fibrosis, inflammation, and can cause amenorrhea and infertility due to abnormal endometrial healing. Histological and Molecular methods were used to evaluate the efficacy of EPO, which is traditionally known for its anti-inflammatory and fibrinolytic properties, in preventing the formation of IUA. Oral administration of EPO reduced the formation of adhesion bands and promoted endometrial regeneration. EPO administration decreased extracellular matrix accumulation, evidenced by the down-regulation of tissue COL1A1 and COL3A1 expression. The anti-inflammatory effect of EPO was confirmed by a reduction in oxidants and down-regulation of pro-inflammatory cytokines including TNF-α, IL-6, IFN-γ, and IL-1β. Furthermore, EPO improved embryonic development parameters, including size and weight of embryo, as well as increased embryo count and live embryo percentage in the rat IUA model. EPO also positively enhanced implantation markers, particularly enlargement and mass gain in the placenta of the treated group, consequently improving pregnancy outcomes such as the number of babies, percent of live babies, baby weight and gestation time. Histopathological investigation provides evidence that oral administration of EPO showed no toxicity on the main three organs including liver, kidney and heart. These results showed that EPO can be considered as a safe and natural product with potent anti-inflammatory and fibrinolytic properties without any observed side effects for the treatment of IUA.

Purpose: Ectopic pregnancy (EP) constitutes 1-2% of all pregnancies. Methotrexate (MTX) is commonly used in treating EP, but it has some limitations and potential side effects. Clinical studies have shown that letrozole, an aromatase inhibitor, may potentially be used in conjunction with MTX therapy.

Background: Chronic salpingitis is one of the most common causes of female infertility. Luteal support is a critical step for embryo transfer. Here, we evaluated the effects of two luteal support regimens, intramuscular progesterone (IMP) and progesterone vaginal gel (VAG), on the pregnancy outcomes in patients with chronic salpingitis undergoing vitrified-warmed embryo transfer.

Background: The World Health Organization has recognized maternal mental illness as an emerging issue. Previous studies have indicated that maternal mental illness is associated with socioeconomic status (SES). However, there is a lack of research concerning the mental health of pregnant people with low SES in Ontario, Canada.

Consensus Preconception Educational Domains for People With Mobility Disabilities: A Delphi Study.

Womens Health Issues

December 2024

Department of Obstetrics, Gynecology and Reproductive Sciences, Magee-Women's Research Institute, School of Medicine, University of Pittsburgh, Pittsburgh, Pennsylvania. Electronic address:

Background: Preconception health education is critical to improve pregnancy and neonatal outcomes, but people with mobility disabilities have specific, often unique issues related to preparing for pregnancy. This study sought to develop consensus-based domains for a preconception education curriculum for people with mobility disabilities.

Methods: We used a mixed methods approach, including a literature review and a Delphi method to develop consensus.

Background: Prevention of alcohol-exposed pregnancy (AEP) involves reducing risky alcohol consumption among women at-risk for pregnancy, using effective contraception among women drinking at risky levels to prevent pregnancy, or both. This study presents the outcomes of a randomized controlled trial assessing the efficacy of Native CHOICES, a culturally tailored adaptation of the CHOICES intervention, among American Indian/Alaska Native (AI/AN) women.

Methods: AI/AN women aged 18-44 who were at-risk for an AEP were randomly assigned in a 1:1 ratio to either the Native CHOICES intervention or a waitlist control group.
