Avid appetite in childhood linked to later eating disorder symptoms      (via sciencedaily.com)     Original source 

The study looked at survey data from 3,670 young people in the UK and the Netherlands to investigate how appetite traits in early childhood might relate to the likelihood of developing eating disorder symptoms up to 10 years later. The researchers found that a particularly high food responsiveness, defined as the urge to eat when you see, smell or taste palatable food, at the ages of four and five was linked to a higher likelihood of reporting a range of eating disorder symptoms at ages 12 to 14.

Oocytes outsmart toxic proteins to preserve long-term female fertility      (via sciencedaily.com)     Original source 

The accumulation of misfolded or damaged proteins in long-lived, non-dividing cells like neurons are linked to neurodegenerative diseases like Alzheimer's. A study now finds that the build-up of these toxic proteins also influences oocyte quality and female fertility. The researchers discovered that mouse oocytes have specialized structures which roam the cytoplasm and act like a clean-up crew which capture and hold onto protein aggregates, rendering them harmless. Failure to degrade the toxic proteins led to the formation of defective eggs. 3 in 5 (60%) of mouse embryos that inherited the toxic proteins failed to complete the very earlies stages of development. The study presents a new frontier to explore the underlying mechanisms of poor oocyte quality, which is the leading cause of female infertility.

Scientists discover new target for reversible, non-hormonal male birth control      (via sciencedaily.com)     Original source 

Scientists discovered a new target for reversible, non-hormonal male birth control. The drug, an HDAC inhibitor, blocked sperm production and fertility in male mice without affecting libido or future reproduction.

A closer look at cannabis use and binge eating      (via sciencedaily.com)     Original source 

New research examined how often people experiencing binge eating are also using cannabis recreationally, and whether patients who use cannabis experience more severe eating disorder symptoms or symptoms of struggling with mental health.

How ovarian tissue freezing could prevent menopause -- possibly forever      (via sciencedaily.com)     Original source 

A new paradigm around the biological processes of menopause is capturing the attention of scientists. The primary question: can menopause be delayed in healthy women, allowing them to extend their child-bearing years -- and perhaps even forestall some of the health risks and uncomfortable symptoms linked to plummeting estrogen levels?

Surprise discovery: For most animals, sperm quality does not reduce with age      (via sciencedaily.com)     Original source 

In humans, male fertility and sperm fitness decline with age, but scientists have made the surprising discovery that this pattern is not consistent in other animals. The team assessed the results of 379 studies which covered a wide range of animals, including mammals, insects, birds, and fish.

Aging mouse sperm affects MicroRNA, increasing the risk of neurodevelopmental disorders      (via sciencedaily.com)     Original source 

Much is known about the added complication to pregnancy when it comes to the age of the mother, but recent studies show that the age of the father can also heighten the risk of neurodevelopmental disorders. A team of researchers has explored the impacts of paternal aging on microRNAs, the molecules that play a crucial role in regulating gene expression.

Infertility: Sperm need a breakthrough for fertilization      (via sciencedaily.com)     Original source 

A new study identifies the defective function of CatSper, an ion channel controlling calcium levels in sperm, as a common cause of seemingly unexplained male infertility. CatSper-deficient human sperm fail to fertilize the egg, because they cannot penetrate its protective vestments. Thus far, this sperm channelopathy has remained undetectable. Scientists have unravelled CatSper's role in infertility using a novel laboratory test that identifies affected men.

Preconception stress may affect health of women undergoing fertility treatment      (via sciencedaily.com)     Original source 

Stress during pregnancy is known to influence health outcomes, but a new study suggests that stress levels before pregnancy are also important to evaluate. Investigators analyzed the link between self-reported stress immediately before conception among women seeking fertility care and blood glucose levels, a marker of heart health. The team found that maternal stress during preconception was associated with higher blood glucose levels, especially among women using intrauterine insemination to conceive and women of higher socioeconomic status.

Nematode proteins shed light on infertility      (via sciencedaily.com)     Original source 

Biologists developed a method for illuminating the intricate interactions of the synaptonemal complex in the nematode C. elegans. The authors identified a trio of protein segments that guide chromosomal interactions, and pinpointed the location where they interact with each other. Their novel method uses a technique known as genetic suppressor screening, which can serve as a blueprint for research on large cellular assemblies that resist traditional structural analysis.

Having a C-section is related to difficulties with conceiving      (via sciencedaily.com)     Original source 

Women who delivered their previous pregnancy by C-section spent a longer time trying to conceive their next pregnancy. Additionally, women who spent a longer time trying to conceive their current pregnancy were more likely to deliver by C-section. The authors concluded that differences in time spent trying to conceive are unlikely to be due to the surgical procedure itself.
