The rise of the global network of nation-states has precipitated social transformations throughout the world. This article examines the role of political and economic globalization in driving fertility convergence across countries between 1965 and 2009. While past research has typically conceptualized fertility change as a country-level process, this study instead employs a theoretical and methodological framework that examines differences in fertility between pairs of countries over time. Convergence in fertility between pairs of countries is hypothesized to result from increased cross-country connectedness and cross-national transmission of fertility-related schemas. I investigate the impact of various cross-country ties, including ties through bilateral trade, intergovernmental organizations, and regional trade blocs, on fertility convergence. I find that globalization acts as a form of social interaction to produce fertility convergence. There is significant heterogeneity in the effects of different cross-country ties. In particular, trade with rich model countries, joint participation in the UN and UNESCO, and joining a free trade agreement all contribute to fertility convergence between countries. Whereas the prevailing focus in fertility research has been on factors producing fertility declines, this analysis highlights specific mechanisms-trade and connectedness through organizations-leading to greater similarity in fertility across countries. Globalization is a process that propels the spread of culturally laden goods and schemas impinging on fertility, which in turn produces fertility convergence.

The size and location of the corpus luteum and the presence of coexistent follicles are crucial factors in synchronizing recipients and determining the suitability for embryo transfer. However, there has been a recent decline in conception rates after embryo transfer, which is attributed to environmental pollution, uterine inflammation, ovarian cysts, and other factors. Therefore, we conducted experiments to establish a novel criterion for successful embryo transfer assessment.

Intensive nitrogen (N) fertilization enhances crop yield but also increases ammonia (NH) and greenhouse gas (GHG) emissions (CO, CH and NO), requiring sustainable fertilization regimes. The co-application of organic and inorganic fertilizers can decrease the use of inorganic fertilizer, reduce environmental pollution, and enhance soil fertility. A simultaneous investigation of the effects of combined application of organic and inorganic fertilizers on NH volatilization, GHG emissions, and soil fertility is, however, lacking.

Background: Zinner syndrome (ZS) is a congenital malformation characterized by a triad of mesonephric (Wolffian) duct dysplasia, first identified by Zinner in 1914. The classical presentation of ZS includes unilateral renal hypoplasia or dysplasia, ipsilateral seminal vesicle cysts, and obstruction of the ejaculatory duct. This case presents a rare variant of the syndrome, where an ejaculatory duct cyst is observed instead of the typical ipsilateral seminal vesicle cyst.

Partners resemble each other in health and education, but studies usually examine one trait at a time in established couples. Using data from all Norwegian first-time parents (N = 187,926) between 2016-2020, we analyse grade point average at age 16, educational attainment, and medical records of 10 mental and 10 somatic health conditions measured 10 to 5 years before childbirth. We find stronger partner similarity in mental (median r = 0.
