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.

A more eco-friendly facial sheet mask that moisturizes, even though it's packaged dry      (via sciencedaily.com)     Original source 

Starting a new year, many people pledge to enact self-care routines that improve their appearance. And facial sheet masks soaked in skin care ingredients provide an easy way to do this. However, these wet masks and their waterproof packaging often contain plastics and preservatives. Now, a study reports a dry-packaged hydrating facial mask that is made of biobased and sustainable materials.

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.

Brain cell discovery sparks hope for fertility treatments      (via sciencedaily.com)     Original source 

Researchers have demonstrated how a specific type of neuron in the brain affects the release of hormones that control ovarian function in females. These findings could help researchers understand and treat reproductive disorders in both animals and humans.

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.

Exposure to air pollution in utero may affect reproductive system development      (via sciencedaily.com)     Original source 

From invisible wafts of diesel exhaust to sun-choking plumes of orange smoke, air pollution is known to damage respiratory well-being. Now, research suggests another reason to hold our breath: Polluted air also may hurt reproductive health.   In a study of air pollution data in relation to markers of reproductive development in infancy, Rutgers researchers found certain pollutants may negatively alter anogenital distance, a measure of prenatal exposure to hormones.

Scientists 3D-print hair follicles in lab-grown skin      (via sciencedaily.com)     Original source 

Scientists have 3D-printed hair follicles in human skin tissue cultured in the lab. This marks the first time researchers have used the technology to generate hair follicles, which play an important role in skin healing and function. When it comes to engineering human skin, hair may at first seem superfluous. However, hair follicles are quite important: They produce sweat, helping regulate body temperature, and they contain stem cells that help skin heal. The finding has potential applications in regenerative medicine and drug testing, though engineering skin grafts that grow hair are still several years away.

Mobile phone use may affect semen quality, study shows      (via sciencedaily.com)     Original source 

Does electromagnetic radiation emitted by mobile phones affect semen quality? While various environmental and lifestyle factors have been proposed to explain the decline in semen quality observed over the last fifty years, the role of mobile phones has yet to be demonstrated. A team has now published a major cross-sectional study on the subject. It shows that frequent use of mobile phones is associated with a lower sperm concentration and total sperm count.
