Published Cheap medicines prevented migraine as well as expensive ones (via sciencedaily.com) Original source
A new study sheds light on what works best to prevent migraine attacks, and surprisingly, cheaper medicines worked as well as the expensive ones.
Published 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.
Published New study finds association between insecticide exposure and lower sperm concentration in adult men (via sciencedaily.com) Original source
Researchers have found in a new systematic review that there is a strong association between insecticide exposure and lower sperm concentration in adult men globally.
Published For epilepsy, yoga may be good for your mind (via sciencedaily.com) Original source
For people with epilepsy, doing yoga may help reduce feelings of stigma about the disease along with reducing seizure frequency and anxiety, according to new research.
Published 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.
Published Sperm adjust their swimming style to adapt to fluctuating fluid conditions (via sciencedaily.com) Original source
Sperm can modulate their energetics by regulating their flagellar waveform -- how the sperm oscillate their tails -- in order to adapt to varying fluid environments, potentially optimizing their motility and navigation within the reproductive tract, according to new research.
Published COVID vaccination in female, male partners does not increase risk of miscarriage, study finds (via sciencedaily.com) Original source
A new study provides deeper insight into the safety of COVID-19 vaccines for people planning to become pregnant. The study found no increased risk of early or late miscarriage as a result of male or female partners getting a COVID-19 vaccine prior to conceiving.
Published Possible cause of male infertility (via sciencedaily.com) Original source
Mature spermatozoa are characterized by an head, midpiece and a long tail for locomotion. Now, researchers have found that a loss of the structural protein ACTL7B blocks spermatogenesis in male mice. The cells can no longer develop their characteristic shape and remain in a rather round form. The animals are infertile.
Published Membrane transporter ensures mobility of sperm cells (via sciencedaily.com) Original source
Special proteins -- known as membrane transporters -- are key to the mobility of sperm cells. A research team has, with the aid of cryo-electron microscopy, succeeded in decoding the structure of such a transporter and its mechanism. These findings will enable a better understanding of the molecular foundations of reproductive capacity and could, in the long term, contribute to developing new approaches to treating fertility disorders and new methods of specific contraception.
Published Study suggests that having common ancestors can jeopardize fertility for generations (via sciencedaily.com) Original source
New research provides rare direct evidence showing that increased homozygosity -- meaning two identical alleles in a genome -- leads to negative effects on fertility in a human population.
Published Bacteria can enhance host insect's fertility with implications for disease control (via sciencedaily.com) Original source
New research reveals how the bacteria strain Wolbachia pipientis enhances the fertility of the insects it infects, an insight that could help scientists increase the populations of mosquitoes that do not carry human disease.
Published Heated yoga may reduce depression symptoms, according to recent clinical trial (via sciencedaily.com) Original source
In a randomized controlled clinical trial of adults with moderate-to-severe depression, those who participated in heated yoga sessions experienced significantly greater reductions in depressive symptoms compared with a control group.
Published Why do some men not produce sperm? (via sciencedaily.com) Original source
Millions of couples worldwide experience infertility with half of the cases originating in men. For 10 percent of infertile males, little or no sperm are produced. Now, new research is shedding light on what may be going wrong in the process of sperm formation, leading to potential theories on possible treatments.
Published Study finds men's antidepressant use did not negatively impact IVF success (via sciencedaily.com) Original source
In vitro fertilization (IVF) is a time-intensive and often stress-inducing fertility procedure. Yet how does that stress impact its success? Investigators have now assessed the effects of anxiety and depression in men on fertility and IVF outcomes.
Published Researchers uncover mechanism that links NAD+ to fertility problems (via sciencedaily.com) Original source
A woman's fertility normally decreases by her late 30s with reproductive function eventually ceasing at menopause. It is known that a small molecule called nicotinamide adenine dinucleotide (NAD+) plays a critical role in this decline, and scientists have revealed how this happens and have identified potential new approaches to enhance reproductive longevity.
Published Omega watch: Researchers develop new blood test for measuring levels of critical omega-3 fatty acids (via sciencedaily.com) Original source
Researchers have discovered a convenient new way to track levels of omega-3 fatty acids in the bloodstream, making it much easier to access information that is critical to cardiovascular and cognitive health, but which has previously been challenging to gather. While the human body can generate most of the fats it needs, it cannot produce adequate levels of omega-3 fatty acids and must obtain them from dietary sources.
Published Researchers studied thousands of fertility attempts hoping to improve IVF (via sciencedaily.com) Original source
By genetically testing nearly one thousand embryos, scientists have provided the most detailed analysis of embryo fate following human in vitro fertilization.
Published Mature sperm lack intact mitochondrial DNA (via sciencedaily.com) Original source
New research provides insight about the bedrock scientific principle that mitochondrial DNA -- the distinct genetic code embedded in the organelle that serves as the powerplant of every cell in the body -- is exclusively passed down by the mother.
Published When it comes to starting a family, timing is everything (via sciencedaily.com) Original source
A new review of methods to increase chances of successful conception suggests that timed intercourse using urine ovulation tests probably improves live birth and pregnancy rates in women under 40 who had been trying to conceive for less than 12 months, compared to intercourse without ovulation prediction.
Published Socioeconomic status may be an uneven predictor of heart health (via sciencedaily.com) Original source
The benefits of four measures of socioeconomic status (education, income, employment status and health insurance) on ideal heart health were greater for non-Hispanic white adults compared to Black, Hispanic and Asian adults in the U.S.
