Background: Nitrous oxide (NO) is a frequently used anaesthetic. Since the year 2000, recreational use of NO, also known as 'laughing gas', became popular as a recreational drug due to its mild effect. In the 1980s, several reports warned against NO-induced reproductive risks among healthcare personnel, questioning the occupational safety of NO in health care.
Methods: Data about the reproductive risks of NO were collected from literature.
Results: Particularly in the past, professionals working in dental and midwifery practices, operating theatres and ambulance transport were exposed to high levels of NO. Adverse reproduction effects included congenital anomalies, spontaneous abortion and reduced fertility rates in females. Following occupational measures, like maximal exposure limits for ambient NO, this occupational risk was considerably reduced. Recreational users of NO, however, voluntarily and repeatedly expose themselves to (very) high doses of NO. As such, they exceed the health exposure limits some hundred times, but they are fully unaware of the related reproductive risks.
Conclusion: We advocate to increase the awareness in recreational N2O-users about its potential reproductive risks, especially in heavy users, pregnant users or those who intend to become pregnant.

Buprenorphine and postpartum contraception utilization among people with opioid use disorder: a multi-state analysis.

Background: The postpartum period provides an opportunity for birthing people with opioid use disorder (OUD) to consider their future reproductive health goals. However, the relationship between the use of medication for opioid use disorder (MOUD) and contraception utilization is not well understood. We used multistate administrative claims data to compare contraception utilization rates among postpartum people with OUD initiating buprenorphine (BUP) versus no medication (psychosocial services receipt without MOUD (PSY)) in the United States (US).

Background: Overweight and obesity-chronic illnesses in which an increase in body fat promotes adipose tissue dysfunction and abnormal fat mass resulting in adverse metabolic, biomechanical, and psychosocial health consequences-negatively impact female fertility. Adverse conception outcomes are multifactorial, ranging from poor oocyte quality and implantation issues to miscarriages and fetal health issues. However, with the advent of novel pharmacologic agents, significant weight loss can be achieved, improving the chances of healthy pregnancies, and their use should be considered during periconceptual counseling.

Background And Objective: Esophageal cancer (EC) is the seventh most prevalent cancer globally and the sixth leading cause of cancer-related mortality. This study aimed to provide an updated stratified assessment of rates in EC incidence, mortality, and disability-adjusted life-years (DALYs) from 1990 to 2021 by sex, age, and Socio-demographic Index (SDI) at global, regional, and national levels, as well as to project the future trends of EC both globally and regionally.
Methods: Data about age-standardized rates (ASRs) of incidence (ASIR), mortality (ASDR), probability of death (ASPoD) and DALYs (ASDALYRs) of EC were obtained from the 2021 Global Burden of Disease (GBD) study.
Association between cardiometabolic index and risk of testosterone deficiency in adult men: a cross-sectional study.

Department of Urology, The Third Affiliated Hospital of Soochow University, Changzhou, Jiangsu, China.
Background: Metabolic health is closely related to testosterone levels, and the cardiometabolic index (CMI) is a novel metabolic evaluation metric that encompasses obesity and lipid metabolism. However, there is currently a lack of research on the relationship between CMI and testosterone, which is the objective of this study.
Methods: This study utilized data from the National Health and Nutrition Examination Survey (NHANES) cycles from 2011 to 2016.
Considering the use of GLP-1 receptor agonists in women with obesity prior to pregnancy: a narrative review.

Purpose: Metabolic disease, including obesity and type 2 diabetes, are amongst the most significant health issues facing women of reproductive age. To date, no antenatal weight management tools have reduced the risk of adverse health outcomes for women with obesity and their offspring, resulting in a shift in focus to the pre-conception period. Although not yet recognised in most international weight management guidelines, glucagon-like peptide-1 receptor agonists (GLP-1 RAs) are being increasingly used for weight management prior to conception.
