Fertility preservation in boys treated for cancer: evaluating the impact of harvesting testicular tissue at young age on the later pubertal development and fertility (prospective study) Vrije Universiteit Brussel

Surgical clinical sciences, Clinical sciences, Basic (bio-) Medical Sciences
The number of childhood cancer survivors has increased thanks toadvances in cancer treatment. Although for long it was assumed thatchildren were more resistant to cancer treatment, now, there isenough evidence that they are also at risk for lifelong sterility. Sincespermatogenesis only starts at puberty, prepubertal boys cannotbenefit from sperm banking before treatment. Because the progenitorcells (spermatogonial stem cells) are present in the ...

Fertility preservation in boys treated for cancer: what is the effect of harvesting testicular tissue in childhood on their later pubertal development and fertility? Vrije Universiteit Brussel

The survival rate of children diagnosed with cancer has improved thanks to more effective radio- and chemotherapy. Although for long it was assumed that children were more resistant to gonadotoxic treatments, now, we know that they are at risk for lifelong sterility too. Since spermatogenesis only starts after puberty, pre-pubertal boys cannot benefit from semen banking before treatment. Because the progenitor cells (spermatogonial stem cells or ...

Impact of soil fertility on photosynthesis and photosynthate allocation in undisturbed primary rainforests in French Guiana University of Antwerp

Ivan Janssens
Plant and Ecosystems (PLECO) - Ecology in a time of change
Tropical forests are among the most diverse ecosystems in the world and account for more than one third of global primary productivity. Tropical rainforests thus play a key role in the global carbon (C) balance. Most tropical forests are phosphorus (P) rather than nitrogen (N) limited, in contrast to the much better studied temperate and boreal forests. The effects of soil fertility on C cycling in tropical rainforests is, however, still poorly ...

Fertility Frontiers: A global history of transnational reproduction in Belgium from cross-feminist perspective Ghent University

Katrien De Graeve
Department of History, Department of Languages and Cultures

The global demise in intercountry adoption procedures is opening up newer, technologically advanced fertility frontiers, including transnational egg donation and surrogacy, through which infertile couples are building the biogenetic families of their dreams. Rather than understanding assisted reproductive technologies through the U+201Chyperbole of radical noveltyU+201D (Franklin, 2007), this research resituates them within older yet ongoing ...

Precarious family lives and the recent fertility downturn in Europe KU Leuven

Jan Van Bavel
Centre for Sociological Research

This project investigates the role of precarious family lives among low educated people in the recent downturn of total fertility in Europe. While a recovery of fertility was expected with the recovery of European economies after the 2008 Recession, a continued fertility decline has been observed in many countries. In the past, fertility below the replacement level has been associated with prolonged participation in education, particularly ...

Bridging gaps: Integration of on-farm phenotypic and genotypic data to improve monitoring and decision-support in dairy cattle - application on fertility KU Leuven

Ben Aernouts
Animal and Human Health Engineering (A2H)

Sustainable food production remains one of the biggest and most timely modern-day challenges. In dairy farming, sustainability is strongly linked with reproduction performance of the cows. Unfortunately, improving cow fertility and conception have proven challenging because they depend on many physiological, genetic and environmental factors and their interactions. Better support of farmers in their decision making on which cows to inseminate ...

Using dynamic microsimulation as an integrated modelling framework to assess the impact of individual-level and contextual factors on past and future fertility trends. University of Antwerp

Karel Neels
Centre for Population, Family and Health
Low fertility levels in European countries since the 1970s have been a major force contributing to population ageing. Several individual-level and contextual factors have been proposed to explain changing patterns of fertility, with increasing education and labour force participation, variation in economic cycles and lack of supportive policies in many countries figuring prominently. With the increase of migration since the late 1990s, the ...

Be Better Informed About Fertility. Giving voice to citizens towards improving assisted reproduction technologies for society (B2-Inf). University of Antwerp

Kristien Hens
Center for Ethics
B2-InF promotes Responsible Research and Innovation (RRI) and public participation in the field of Assisted Reproduction Technologies (ART), in order to align its scientific exercise and dissemination with the knowledge, concerns and expectations of populations (18-30 year-old) in Belgium, Switzerland, Italy, Spain, Macedonia, Albania, Slovenia and Kosovo. How? 1) By collecting, analyzing and transferring social scientific knowledge, ...
