A new study reveals that chromosomally 'abnormal' embryos can still result in pregnancy through IVF, with the potential for self-correction and development into a healthy fetus. The extent of mosaicism influences clinical outcomes, suggesting priority should be given to mosaic embryos with low aneuploidy levels.
Spain now holds the pace of European ART with over 100,000 cycles performed annually, resulting in a steady pregnancy rate of around 35%. The data collected by ESHRE also reveals that IVF remains more successful than ICSI, but pregnancy rates from egg donation continue to rise.
A study has shown that an inexpensive fertility drug can be just as effective as more recent reproductive hormones in treating unexplained infertility. The 50-year-old drug, taken orally, was found to have a comparable pregnancy rate to newer hormones used in intrauterine insemination (IUI) with ovarian stimulation.
A large population study found that female cancer survivors are 38% less likely to achieve a pregnancy than women in the general population. The detrimental effect on fertility was evident in almost all types of cancer diagnosed, with variations between different cancer diagnoses.
Researchers have discovered rare gene variants in Finnish mothers that protect them from pre-eclampsia. The study found two single nucleotide polymorphisms in the sFlt-1 protein gene linked to lower risk of pre-eclampsia.
A new study of almost 19,000 IVF treatment cycles reveals that the age of the male partner significantly affects live birth success rate. The study found a decline in cumulative incidence of live birth with increasing male partner age, particularly among women aged 30-35 and those over 40.
Most reproductive-age and pregnant women who use opioids for non-medical purposes also use at least one other substance, including nicotine, alcohol, or cocaine. This finding suggests that public health efforts addressing the opioid epidemic should include interventions targeting concurrent use of multiple substances among these women.
A multi-year study of southern resident killer whales found up to two-thirds of pregnancies failed due to nutritional stress, primarily caused by low or variable Chinook salmon abundance. The research suggests that boosting salmon runs could help the population recover.
A new trial by University of Exeter researchers found that taking low-dose aspirin before bed can reduce the risk of pre-eclampsia, a condition causing premature birth and maternal and foetal death. The study showed a 62% reduction in pre-term preeclampsia rates.
