Pregnancy complications such as miscarriage, pre-eclampsia, diabetes in pregnancy (gestational diabetes) and pre-term birth are linked to a heightened risk of heart disease in later life, suggests an overarching (umbrella) analysis of data. Several other factors related to fertility and pregnancy also seem to be associated...
Placenta development is initiated first in human pregnancies, even before the embryo starts to form, according to new research. A team of scientists at the Francis Crick Institute, London, has found that one of the first steps after egg fertilisation in mammals is the initiation of...
Males who suffer from moderate or severe cases of COVID-19 could experience reduced fertility, according to a new study conducted by Dr. Dan Aderka of Sheba Medical Center. Aderka reported that not only was the virus found within the sperm of some 13% of screened male...
New research helps explain why flu can lead to life-threatening complications during pregnancy, suggesting the virus does not stay in the lungs but spreads throughout the mother's body. The pre-clinical study has overturned current scientific thinking on the reasons why flu infections affect pregnant women and...
The use of frozen rather than fresh embryos in IVF does not increase the chance of a successful pregnancy, newly published data shows. The findings discourage the 'freeze-all' strategy adopted by some fertility clinics in recent years. They thought that using frozen embryos rather than immediately...
Men might want to think twice before reaching for their smartphone at night. A new study found correlations between electronic media use at night and poor sperm quality. Preliminary results show that greater self-reported exposure to light-emitting media devices in the evening and after bedtime is...
Researchers sought to investigate the effects of endometrioma and the impact of bilaterality on in vitro fertilization (IVF) and intracytoplasmic sperm injection (ICSI) outcomes. A Turkish study has found that that presence of endometrioma in patients with endometriosis negatively impacts fertility parameters, but has no effect...
The female reproductive tract has the final say in human mate choice, according to new research from the University of Eastern Finland. Achieving pregnancy has been shown to be more likely between partners who carry dissimilar human leucocyte antigen (HLA) immune genes. Accordingly, humans are expected to...
Infertility affects 10% to 15% of couples globally, and while often viewed as a women's health problem, men contribute to around half of the cases. A new male fertility test based on Cornell research could help predict which men might need treatment and which couples might...
Pregnant women infected with COVID-19 may pass on the disease-causing virus to their baby through the placenta, researchers in France suggest. In their study, published in Nature Communications, the authors describe the case of a newborn child which presented with SARS-CoV-2 infection shortly after birth and...
