Purpose: Does IDEF mapping help monitor the technical process of IUI and explore the potential improvements which might contribute to increased pregnancy and live birth rates?

Method: Retrospective analysis of 1729 homologous IUI cycles of couples attending a fertility clinic in a university hospital setting. Standardized conventional semen parameters were analyzed and the semen samples prepared via discontinuous density gradient centrifugation.

Results: There was no significant association between sperm concentration, motility and morphology (analysis phase), and pregnancy outcome. Only female and male ages were significantly associated with the pregnancy outcome. There was a significant difference in the odds on clinical pregnancies and live births when analysis was ≤ 21 min initiated, and < 107 min between sample production and IUI, adjusted for male and female age.

Conclusions: Adjusting for the couple's age, we could show that time intervals between semen production and analysis and IUI when kept low significantly influenced clinical pregnancies and live births.

Safety profiles of fondaparinux in pregnant women: a systematic review and meta-analysis.

Eur J Clin Pharmacol

January 2025

Department of Obstetrics and Gynaecology, West China Second University Hospital, Sichuan University, No. 20, Renmin South Road, Section 3, Chengdu, 610041, Sichuan Province, China.

Background: The prevalence of conditions necessitating anticoagulation therapy among pregnant women has been steadily increasing. Although low-molecular-weight heparin (LMWH) is commonly used, several studies have investigated the use of fondaparinux in pregnant women. However, the safety profile of fondaparinux in this population remains to be fully elucidated.

Purpose: Given the lack of available and effective interventions to address the detrimental consequences of perinatal exposure to intimate partner violence (IPV) on maternal mental health, and reported very low access to IPV-related mental health services in Mexico, we examined the feasibility and efficacy of a culturally adapted, virtual, brief group psychosocial intervention designed to improve maternal mental and physical health and reduce IPV revictimization for pregnant women exposed to IPV. In this pilot randomized controlled trial, we evaluated maternal outcomes after participation in the Pregnant Moms' Empowerment Program (PMEP) in Mexico.

Methods: Women were recruited from social service agencies and health centers in the community, as well as social media advertisements that targeted pregnant women living in Mexico.

Breastfeeding provides essential nutrition and disease protection for infants while reducing the risk of type 2 diabetes and breast cancer in mothers. Despite these benefits, significant racial and ethnic disparities exist in breastfeeding initiation, particularly among Black women. This study examines racial differences in the receipt of breastfeeding information from varying sources and their association with breastfeeding initiation.

Sex hormone-binding globulin (SHBG) regulates sex hormone availability and is influenced by metabolic factors. Variations in SHBG levels during pregnancy may affect the development of hypertensive disorders such as gestational hypertension (GH) and preeclampsia (PE). This systematic review and meta-analysis explores the potential of SHBG as a biomarker for predicting GH and PE.
