Published Research challenges current thinking on the genetic causes of very early menopause



The genetic causes of very early menopause will have to be reconsidered after researchers found that nearly all women who carried variations thought to cause the condition in fact had their menopause at an older age.
Published Helping 'good' gut bacteria and clearing out the 'bad' -- all in one treatment



Probiotics can help maintain a healthy gut microbiome or restore populations of 'good bacteria' after a heavy course of antibiotics. But now, they could also be used as an effective treatment strategy for certain intestinal diseases, such as Crohn's disease. Researchers have developed a microgel delivery system for probiotics that keeps 'good' bacteria safe while actively clearing out 'bad' ones. In mice, the system treated intestinal inflammation without side effects.
Published One in five women become pregnant naturally after having a baby conceived with IVF



New research analyzed data from 11 studies of over 5,000 women around the world between 1980 and 2021, to evaluate how common it is to get pregnant naturally after having a baby conceived by fertility treatment. Around 20% of women who needed fertility treatment, such as IVF, to conceive their first child are likely to get pregnant naturally in the future, finds a new study.
Published New diagnostic finds intact sperm in infertile men



Researchers develop new diagnostic tool to visualize protein biomarkers of well-developed sperm to determine if surgical sperm extraction may be successful for certain infertile men.
Published Elimination of type of bacteria suggests treatment for endometriosis



A research group has discovered that using an antibiotic to target Fusobacterium, a common bacterium that causes inflammation, improved the symptoms of endometriosis. Their findings suggest an alternative treatment for the disease.
Published New research identifies cells linking chronic psychological stress to inflammatory bowel disease



For the first time, cells involved with the communication between stress responses in the brain and inflammation in the gastrointestinal (GI) tract have been identified in animal models. Glial cells, which support neurons, communicate stress signals from the central nervous system (CNS) to the semi-autonomous nervous system within the gastrointestinal (GI) tract, called the enteric nervous system (ENS). These psychological stress signals can cause inflammation and exacerbate symptoms of inflammatory bowel disease (IBD).
Published Researchers successfully induce primate oocytes in the lab



The many types of cells in the human body are produced through the process of differentiation, in which stem cells are converted to more specialized types. Currently, it is challenging for researchers to control the differentiation of stem cells in the lab (in vitro). Of particular interest are oocytes, which are female germ cells that develop into eggs. Understanding their development could have far-ranging impacts, from infertility treatment to conservation of endangered species. A new study has successfully induced meiotic (dividing) oocytes from the embryonic stem cells of cynomolgus monkeys, which share many physiological traits with humans. By establishing a culture method for inducing the differentiation of meiotic oocytes, the researchers aimed to shed light on germ cell development in both humans and other primates.
Published Happy worms have healthy eggs



Researchers have exposed roundworms (a well-established model organism in biological research) to selective serotonin reuptake inhibitors (SSRIs), a class of drugs used for treating depression and anxiety. Surprisingly, this treatment improved the quality of aging females' egg cells.
Published Scientists discover the dynamics of an 'extra' chromosome in fruit flies



Most chromosomes have been around for millions of years. Now, researchers have revealed the dynamics of a new, very young chromosome in fruit flies that is similar to chromosomes that arise in humans and is associated with treatment-resistant cancer and infertility. The findings may one day lead to developing more targeted therapies for treating these conditions.
Published Study gives insight into cause of severe inflammatory bowel disease



Investigators have identified a genetic variant that increases people's risk of developing perianal Crohn's disease, the most debilitating manifestation of Crohn's disease. The variant generates changes to DNA that lead to a loss of protein function, which in turn, alters how the body recognizes and handles bacteria, making it less effective at fighting infections.
Published Diet high in fruit and vegetables linked to lower miscarriage risk



A preconception and early-pregnancy diet that contains lots of fruit, vegetables, seafood, dairy, eggs and grain may be associated with reducing risk of miscarriage, a new review of research suggests.
Published New genetic target for male contraception identified



Discovery of a gene in multiple mammalian species could pave the way for a highly effective, reversible and non-hormonal male contraceptive for humans and animals. Researchers identified expression of the gene, Arrdc5, in the testicular tissue of mice, pigs, cattle and humans. When they knocked out the gene in mice, it created infertility only in the males, impacting their sperm count, movement and shape.
Published Time-restricted fasting could cause fertility problems



Researchers have found that time-restricted fasting could cause fertility problems. Time-restricted fasting is an eating pattern where people limit their food consumption to certain hours of the day. It's a popular health and fitness trend and people are doing it to lose weight and improve their health. But the new study shows that time-restricted fasting affects reproduction differently in male and female zebrafish. Importantly, some of the negative effects on eggs and sperm quality can be seen after the fish returned to their normal levels of food consumption. The research team say that while the study was conducted in fish, their findings highlight the importance of considering not just the effect of fasting on weight and health, but also on fertility.
Published Study sheds light on how IBD can develop



A new study could help improve personalized medicine approaches in inflammatory bowel disease by understanding how patients with variants in the PTPN2 gene develop IBD.
Published New technology to select healthier sperm for IVF success



Scientists have developed new technology to help couples undergoing in-vitro fertilization (IVF) due to male fertility problems to increase their chances of success in having a baby.
Published Study to decode microbe-gut signaling suggests potential new treatment for IBD



Fresh insights into how our bodies interact with the microbes living in our guts suggest that a two-drug combination may offer a new way to treat inflammatory bowel diseases such as Crohn's disease and ulcerative colitis.
Published Engineered E. coli delivers therapeutic nanobodies to the gut



Researchers have succeeded in developing an E. coli-based 'smart microbe' that secretes therapeutic payloads, including antibodies, into the gut. The genetically modified beneficial strain of bacteria blocks intestinal inflammation in a preclinical model of inflammatory bowel disease and has the potential to treat intestinal-based diseases.
Published Ending THC use may reverse its impacts on male fertility, research shows



A previous study confirmed that chronic use of cannabis may greatly impact male fertility and reproductive outcomes in nonhuman primates -- but it was unclear whether the effects are permanent. Now, new research has confirmed that discontinuing use of THC can at least partly reverse these effects, according to a new study.
Published Disproportionate percentage of females with unexplained infertility have gene variants known to cause heart problems, cancer



About 17% of women with unexplained infertility also have gene variants known to cause disease, from common conditions like heart disease to rare problems like ALS, researchers report.
Published Humans bite back by deactivating mosquito sperm



New research makes it likely that proteins responsible for activating mosquito sperm can be shut down, preventing them from swimming to or fertilizing eggs.
