Since the successful introduction of in vitro fertilization in 1978, medically assisted reproduction (MAR) has proliferated in multiple clinical innovations. Consequently, egg cells have become an object of demand for both infertility treatment and stem cell research, and this raises complex legal, ethical, social and economic issues.In this paper we compare how the procurement and use of human egg cells is regulated in two countries: Israel and Austria. Israel is known for its scientific leadership, generous public funding, high utilization and liberal regulation of assisted reproductive technology (ART). Austria lies at the other extreme of the regulatory spectrum in terms of restrictions on reproductive interventions.In both countries, however, there is a constant increase in the use of the technology, and recent legal developments make egg cells more accessible. Also, in both countries the scarcity of egg cells in concert with the rising demand for donations has led to the emergence of cross-border markets and global 'reproductive tourism' practices. In Israel, in particular, a scandal known as the 'eggs affair' was followed by regulation that allowed egg cell donations from outside the country under certain conditions.Cross-border markets are developed by medical entrepreneurs, driven by global economic gaps, made possible by trans-national regulatory lacunae and find expression as consumer demand. The transnational practice of egg cell donations indicates the emergence of a global public health issue, but there is a general lack of medical and epidemiological data on its efficacy and safety. We conclude that there is need for harmonisation of domestic laws and formulation of new instruments for international governance.

The evolution of green plants from aquatic to terrestrial environments is thought to have been facilitated by the acquisition of gametangia, specialized multicellular organs housing gametes. Antheridia and archegonia, responsible for producing and protecting sperm and egg cells, undergo formative cell divisions to produce a cell to differentiate into germ cell lineages and the other cell to give rise to surrounding structures. However, the genes governing this process remain unidentified.

Background: The lactation period is a crucial period where the nutritional status and the mother's environment influence milk production, impacting organ differentiation, function, and structure in the baby's body.
Aim: The study aimed to determine the impact of providing lactating rats with quail egg supplements enriched with marine macroalgae on their physiological condition (blood cells, lipids, blood glucose, antioxidant activity, and prolactin hormone levels) and the growth of their offspring.
Methods: The study involved 25 lactating Sprague Dawley white rats aged 3 months old and weighing approximately 200 g divided into five treatment groups thus; T0 as the control, T1 with quail eggs enriched with commercial feed, T2 with quail eggs enriched with 3% of marine macroalgae, T3 with quail eggs enriched with 4% of marine macroalgae, and T4 with quail eggs enriched with 5% of marine macroalgae, which received one quail egg for 21 days.

Background: Local hen layers play a crucial role in egg production and the poultry industry. Optimizing their performance, egg quality, and overall health is of paramount importance.
Aim: This research aims to examine the effects of different feed forms on gut bacteria and subsequent effects on productivity, egg quality, and intestinal morphology in indigenous laying hens.

Purpose: Previous studies have suggested a link between serum progesterone levels on the day of the HCG trigger in IVF cycles and oocyte and embryo quality. This study aims to explore this relationship more thoroughly.
Methods: This study included 496 infertility patients at Moloud Infertility Treatment Center, Zahedan, Iran.

This study aimed to evaluate the effects of different dietary supplementation levels with jujube fruit powder on the performance, biochemical parameters, and egg quality characteristics of laying quails. A total of 60 quails (45 days old) were randomly assigned to treatments with different levels of jujube fruit powder: a basal diet (control) and diets supplemented with 5 g/kg (T1), 10 g/kg (T2), with five replicates per treatment (20 quails/treatment and four quails/replicate). The differences between 1-15 and 16-30 days for feed intake (p<0.
