Does a nut-rich diet lead to better sperm quality?
Sperm count is on the decline in Western societies, according to recent studies, which means that men’s reproductive health is suffering. How can it be improved? A healthful diet that is abounding in nuts might help, researchers suggest. In 2017, a large meta-analysis focusing on men’s reproductive health in Western countries found that sperm concentration, […]
Animating embryos: thein totorepresentationof life
In the preface to the tenth and latest edition of his authoritative textbook on developmental biology, Scott F. Gilbert states that the science of becoming is currently itself undergoing a ‘metamorphic molt’, at the end of which there will be an as ‘yet unnamed developmental science’. 1 To a large extent, systems biology is responsible […]
Should we forget about embryos till day 5?
INTRODUCTION On the basis of bibliography of the last years, there is a trend toward blastocyst transfer rather than cleavage embryo transfer. There are several studies that point out that blastocyst transfer could achieves better results [1&]. Culture media is one of the most important factors in in-vitro fertilization (IVF); it can affect live birth […]
Cell and genetic predictors of human blastocyst hatching success in assisted reproduction
The aim was to identify cell and genetic predictors of human blastocyst hatching success in assisted reproduction programmes via a prospective case-control study. Blastocysts, donated by couples in assisted reproduction programmes were used. Hatching success assessment was performed after 144-146 h post-fertilization. The mRNA expression levels of cathepsin V (CTSV), GATA-binding protein 3 (GATA3) and […]

Taking paracetamol during pregnancy may reduce fertility of daughters
Taking paracetamol during pregnancy may impair the future fertility of female offspring, according to a review published in Endocrine Connections. The article reviews three separate rodent studies that all report altered development in the reproductive systems of female offspring from mothers given paracetamol during pregnancy, which may impair their fertility in adulthood. Paracetamol, or acetaminophen, […]

Fertility breakthrough: New research could extend egg health with age
Princeton University researchers led by Coleen Murphy have identified a key protein in old, poor-quality C. elegans oocytes (unfertilized eggs): cathepsin B. When they administered a cathepsin B inhibitor midway through the fertile window — on day 3 of the worms’ adulthood, the equivalent of a woman in her early 30s — they successfully extended […]
Low total testosterone in men widespread, linked to chronic disease
A male’s total testosterone level may be linked to more than just sexual health and muscle mass preservation, a new study finds. Low amounts of the hormone could also be associated with chronic disease, even among men 40 years of age and younger. “If we look at data for men from a population level, it […]
Like babies, eggs send signals when ‘hungry’
A growing oocyte in the middle, which is very large with a bright green rim, surrounded by many small red follicle cells whose nuclei are stained blue. The thin bright-green hair-like structures between them are the feeding tubes, which grow out from the follicle cells when they receive signals from the oocyte. This image was […]
