Ignacio Campo the chances of a successful birth through , according to a new study. Researchers found that exposure to fine particulate matter (PM) before the retrieval of eggs during can slash the odds of achieving a live birth by almost 40%. The pioneering study analyzed PM10 exposure in the two weeks leading up to egg collection, finding the odds of a live birth.
Conducted over eight years in Perth, Australia, the research team analyzed 3,659 frozen embryo transfers from 1,836 patients. The average age of the women was 34.5 at the time of egg retrieval and 36.
1 at the time of frozen embryo transfer. The study examined air pollutant concentrations over four exposure periods prior to egg, or oocyte, retrieval: 24 hours, two weeks, four weeks, and three months. Increasing PM2.
5 exposure in the three months prior to egg retrieval was also associated with decreased odds of live birth. The research team pointed out that the negative impact of was observed despite excellent overall air quality during the study period. Chris LeBoutillier Study lead author Dr.
Sebastian Leathersich said: "This is the first study that has used frozen embryo transfer cycles to separately analyze the effects of pollutant exposure during the development of eggs and around the time of embryo transfer and early pregnancy. "We could therefore evaluate whether pollution was having an effect on the eggs themselves, or on the early stages of pregnancy. “Our results reveal a negative linear association betw.
