Penile microbiome composition can vary; however, the presence of some bacterial vaginosis-related bacteria correlates with bacterial vaginosis onset in their female partners. Results highlight 10 bacteria that could be used to accurately predict bacterial vaginosis incidence in women. The study suggests that treatment manipulating the penile microbiome may reduce BV incidence in sex partners.
A breakthrough in fertility science by researchers from Bristol and Mexico has shattered the universally accepted view of how sperm 'swim'.
The study, published in Science Advances, reveals that cells can detect the presence of different mitochondrial genomes and select among them according to their effect on metabolic status
Millions of women have been taking oral contraceptives, but little is known about whether the synthetic hormones found in the oral contraceptives have behavioural and neurophysiological effects, especially during puberty and early adolescence, which are critical periods of brain development. A uOttawa team of researchers found that oral contraceptive use is related to significant structural changes in brain regions implicated in memory and emotional processing. It also alters stress reactivity.
A pair of recently published studies analyzed how ovarian function in mice responded to various levels of exposure to glyphosate, a chemical extensively used to kill weeds. The results showed exposure changed the level of some ovarian proteins but did not impact ovarian steroid production, an indication glyphosate may not adversely affect reproduction.
Researchers from the Rovira i Virgili University in collaboration with researchers from the University of Utah have carried out a systematic review and meta-analysis evaluating the association between adiposity (normal weight, overweight, obesity, and low weight) and the sperm quality. Overweight and/or obesity were associated with low semen quality parameters and underweight category was likewise associated with low sperm normal morphology. According to the researchers, this work demonstrates the importance of adiposity in semen quality.
Mothers with COVID-19 infection are unlikely to pass the virus to their newborn babies, if correct hygiene precautions are observed, according to a small observational study published in The Lancet Child & Adolescent Health journal.
Fertility is likely to decline in the wake of the Covid-19 pandemic, a new Bocconi University study finds
A Kobe University led study has revealed for the first time in the world the high frequency of a novel autoantibody in women suffering from recurrent pregnancy loss. It is expected that these results will contribute towards the illumination of the underlying mechanisms behind this disorder, thrombosis, and pregnancy complications such as hypertensive disorders; leading to the development of new treatment methods.
Researchers at the University of Illinois at Urbana-Champaign have used a combination of label-free imaging and artificial intelligence to determine the potential fertility of sperm samples in cattle. The technique may help improve assisted reproductive technology in humans.
