New data model reveals new recommendations for infertility treatment
A new data analysis model developed in part by University of Minnesota faculty is shedding more light on potential treatment for women facing infertility issues, offering possibilities for the future of health recommendation tools.

In a study recently published in the Journal of the American Statistical Association , Carlson School of Management assistant professor Xuan Bi and colleagues examine existing data on 1376 women with polycystic ovary syndrome (PCOS). The condition is one of the most common causes of infertility, but it is not well understood. Why? The data set is reduced.

What advances does the new year hold in the field of infertility?
The fight against the clock to ensure maternity, making up for time lost due to the pandemic, will be one of the great challenges for fertility clinics. A study, published by the journal Reproductive Biomedicine Online, analyzes the effects of Covid-19 mitigation measures on fertility and infertility management practices by different clinics and concludes that most infertility treatments were delayed during the pandemic. Conducted among leading clinics in 43 countries in Asia (13), Africa (3), Europe (17), North America (3), Oceania (2) and South America (5), the study, written by a group of Australian researchers, insists on the need to update treatments, stopped by Covid-19.

Cannabis affects sperm count and motility in two generations of mice
Intense but short-term exposure to cannabis vapor lowered sperm count and slowed sperm movement or motility, not only in directly exposed male mice, but also in their offspring, according to a new study. The findings are based on other research in humans and animals, showing that cannabis can impair male reproductive function. The current study uses more controlled circumstances than human studies, which often have to rely on surveys, and is the first known reproductive study to use vaporized whole cannabis in mice, which is the most common form used by humans. Previous animal studies use other methods of administration such as injections of tetrahydrocannabinol (THC), the main psychoactive component of cannabis.

Their representatives have given some data such as that almost 40% of adults in Spain are overweight and, in addition, it affects their fertility; Severely obese women are 50% less likely to become pregnant, and up to 60% of obese men may suffer from erectile dysfunction. And 20% of them have decreased fertility.

Smoking during pregnancy can harm future pregnancies
Researchers have found that the link between smoking early in pregnancy and having a smaller baby can extend to future pregnancies. Researchers in Southampton have found that the link between smoking early in pregnancy and having a smaller baby can extend to future pregnancies. The findings showed that women who smoked early in their first pregnancy were more likely to have a smaller than expected baby in their second pregnancy compared to nonsmokers. This was even the case where they reported that they stopped smoking early in their second pregnancy.

New test quickly detects bacteria associated with increased risk of preterm birth
A study has found that a new device can quickly and accurately detect changes in vaginal bacteria and corresponding immune responses in pregnant women. These changes are associated with an increased risk of preterm birth. The test could help identify women at risk for preterm labor earlier, which could allow obstetricians to monitor these women more closely and begin preventive treatments earlier and in a more targeted way than is currently possible.

This is according to researchers at the March of Dimes Prematurity Research Center at Imperial College London, who have published their work in Nature Communications.

Choosing the best embryo in In Vitro Fertilization
Each year, tens of thousands of babies are born in the United States as a result of IVF (in vitro fertilization), where several eggs are fertilized outside of the mother's body and then an embryo is selected for transfer to her uterus. For several years, future parents have been able to screen their embryos for rare genetic defects such as cystic fibrosis or Tay-Sachs disease.

However, new technical advances now make it possible for parents to test their embryos for genetic risk factors for diseases such as cancer, diabetes, heart disease, or psychiatric disorders such as schizophrenia.

USPSTF recommends aspirin for people at high risk of preeclampsia
The US Preventive Services Task Force (USPSTF) recommends low-dose aspirin to reduce the risk of pre-eclampsia among people at high risk. This recommendation forms the basis of the final recommendation statement published in the September 28 issue of the Journal of the American Medical Association.

Jillian T. Henderson, Ph.D., MPH, of the Kaiser Permanente Evidence-based Practice Center in Portland, Oregon, and colleagues conducted a systematic review to update the USPSTF evidence on the effectiveness of aspirin in preventing Preeclampsia in individuals at increased risk based on clinical risk factors or measurements. We included data from 23 randomized clinical trials with 26952 participants, including 18 trials among participants at increased risk of pre-eclampsia. The researchers found that the incidence of pre-eclampsia ranged from 4 to 30 percent in the trials of participants at higher risk. Aspirin use was significantly associated with lower risks of preeclampsia, perinatal mortality, and preterm delivery, and intrauterine growth restriction (combined relative risks, 0,85, 0,79, 0,80, and 0,82, respectively). There was no significant association of aspirin use with the risk of postpartum haemorrhage or other haemorrhage-related harm.

Treat infertility with drug-releasing microspheres
For an embryo to survive, it must adhere to the lining of the uterus within a few days of conception. However, if this lining, called the endometrium, is too thin, the embryo cannot latch on. Now, researchers reporting in ACS Biomaterials Science & Engineering have developed a new system aimed at treating infertility in women with thin endometria. Its tiny microscale particles stimulated the growth of blood vessels, producing promising results in preliminary experiments in cells and mice.

Poor blood flow within the endometrium limits its thickness, and researchers have struggled to find an effective way to stimulate the formation of new blood vessels. Some have begun to explore the use of microspheres to deliver treatment. However, current methods for manufacturing these small particles face challenges, including the need for complex and demanding production methods and too much variation in the sizes of the spheres. So Xiangguo Wang, Lei Yang, and their colleagues wanted to devise a simple and efficient technique to fabricate uniform microspheres charged with a compound known to be a powerful stimulator of the crecimiento of blood vessels.

Researchers have found a way to better identify the "golden window" when a uterus is ready for pregnancy, in a discovery that could help increase IVF success rates. The team found that levels of this molecule on the surface of the uterus decrease at a certain point in the menstrual cycle. This allows the uterus to become stickier, opening the "golden window" for successful pregnancy.

The use of electronic cigarettes ("vaping") during pregnancy represents a significant risk to the health of the offspring, since it affects the function of blood vessels even in adulthood, according to a new study by researchers from the Faculty of West Virginia University (WVU) Medicine

The diminished capacity of the blood vessels increases the risk of stroke, heart attack and other cardiovascular problems. This study was conducted using a rat model. Female rats were exposed to e-cigarette aerosol for one hour a day for five days a week during pregnancy. The pups were examined at XNUMX, XNUMX and XNUMX months (adulthood), at which point the adverse effects of vaping were discovered.
