Study discovers lagging chromosomes as one of the major causes of infertility

Why do women over 35 have more difficulty getting pregnant? After discovering one of the causes of age-related female infertility, researchers at the University of Montreal Hospital Research Centre suggest that it will be possible in the future to improve the quality of the eggs of older patients by intervening on the cell cycle level.

Researchers identify key protein that plays an essential role in male fertility

Mammalian sperm cannot fertilize an egg from the get-go. It's an ability acquired only after insemination, during passage through the female reproductive tract, and requires two consecutive, time-sensitive processes to provide sperm with the physical and biochemical traits necessary to complete their fundamental job.

Study reveals mechanism behind male infertility caused by autoimmune disease

Investigators have found that the absence of autoimmune regulator (Aire) in mice results in fertility problems similar to those affecting men with autoimmune polyendocrine syndrome type I (APS-1).

Eggs and embryos go through a more dynamic and complex journey than previously thought

The journey of the egg and the embryo through the fallopian tube or oviduct toward the uterus is not well understood, mainly because it is inaccessible for direct imaging.

Study finds higher risk of pre-eclampsia, hypertension in pregnancies derived from frozen embryos

A large cohort study drawn from the national IVF registry of France, which included almost 70,000 pregnancies delivered after 22 weeks gestation between 2013 and 2018, has found a higher risk of pre-eclampsia and hypertension in pregnancies derived from frozen-thawed embryos.

Higher risk of preeclampsia and pregnancy-induced hypertension as a result of embryo freezing for IVF

Researchers have established a strong association between the risk of developing hypertension and the artificial cycle for frozen-thawed embryo transfer.

New chip mimicking bovine endometrium could play key role in cattle’s pregnancy success

To investigate factors that can jeopardize pregnancy success in cattle, researchers at the University of São Paulo (USP) in Brazil used a kind of chip to mimic the environment of the endometrium, the tissue that lines the inside of the uterus.

Beckman Coulter launches new Access AMH Advanced assay to predict poor ovarian response

Beckman Coulter, a global leader in diagnostics and infertility testing, announced today the launch of the first and only test that uses a validated cut-off to aid in the assessment of ovarian response.

Zebrafish study shows how early exposure to cannabinoids reduces later neural activity

Zebrafish exposed to the leading cannabinoids found in cannabis in the earliest stages of development suffer a significant drop in neural activity later in life, according to a University of Alberta study that has implications for prenatal development in humans.

Researchers review 50 years of progress in women's health

Debates over women's health have long been contentious, but have also resulted in significant improvements in areas like equitable access to health care and survivorship. But the overall picture remains far from perfect.

Pfizer-BioNTech COVID-19 vaccine may not be associated with adverse effects on fertility and breastfeeding, says study

A recent study by researchers in Singapore shows the absence of evidence for adverse effects on fertility or the presence of the vaccine mRNA (messenger ribonucleic acid) in breast milk, following the administration of the Pfizer BNT162B2 COVID-19 vaccine. This supports efforts to prevent the spread of false information about the effects of the vaccine.

Animal and insect invasions could shed light on COVID-19 transmission

Invasions by alien insect and animal species have much in common with outbreaks of infectious diseases and could tell us a great deal about how pandemics spread, according to a research paper published today.

Planned cesarean deliveries may be associated with lower risk of adverse outcomes

New research shows that planned cesarean deliveries on maternal request are safe for low-risk pregnancies and may be associated with a lower risk of adverse delivery outcomes than planned vaginal deliveries.

Gene-regulatory mechanisms at an early embryonic stage govern the flowering behavior of Arabidopsis

Researchers at GMI - Gregor Mendel Institute of Molecular Plant Biology of the Austrian Academy of Sciences - and the John Innes Centre, Norwich, United Kingdom, determine that gene-regulatory mechanisms at an early embryonic stage govern the flowering behavior of Arabidopsis later in development. The paper is published in the journal PNAS.
