The study found that genes involved in female mammalian pregnancy are also activated in male pregnancy, suggesting similar molecular mechanisms.
A mathematical model developed by Rutgers University scientists can help explain why many pregnancies and IVF attempts fail. The study highlights the importance of understanding errors in female cell division, which increase with age and are linked to aneuploidy, a leading cause of early miscarriage and IVF failure.
The evolution of pregnancy in seahorses and pipefishes is linked to modifications of the adaptive immune system. Genomic analysis reveals divergent genomic rearrangements in the MHC II pathway, which may help study immune deficiencies.

The study, based on nationally representative data, also revealed that depression increases vulnerability to cannabis use even among those who perceive substantial risk.
Researchers discovered that female swamp wallabies are permanently pregnant throughout their lives due to two uteri, allowing for continuous embryonic development. This unique reproductive strategy enables females to return to oestrus in late pregnancy and conceive new embryos.
Researchers found that swamp wallabies ovulate and mate while still pregnant, suggesting continuous pregnancy throughout their lives. This unique reproductive strategy challenges the traditional view of marsupial reproduction and may have implications for our understanding of female fertility.
A study of over 6,000 newborn babies found that longer pregnancies are associated with chemical DNA changes in thousands of genes. These epigenetic modifications may influence fetal organ development and potentially affect the health of premature birth children.
Researchers confirm swamp wallabies ovulate and mate while carrying a full-term fetus, creating a unique reproductive strategy that supports continuous embryo development. This phenomenon allows the female to be pregnant throughout her reproductive life, exceeding the duration of the oestrous cycle.
