Quick Overview:

Medical research on pregnancy spans conditions from asthma and endometriosis to environmental chemical exposure, with studies linking factors as varied as air pollution, PVC flooring, antacid use, and hormonal contraception to maternal and fetal outcomes. A Newcastle study has identified a significant connection between pregnancy treatment and childhood asthma, while separate research found soot air pollution particles reaching the placentas of London mothers. Women with endometriosis face elevated risks during pregnancy, including premature birth, and a Danish cohort study examined the relationship between hormonal contraception and ovarian cancer in women of reproductive age. This resource compiles pregnancy medical studies organized by topic — including folic acid, endometriosis, air pollution, and asthma — to help patients and clinicians navigate the current evidence base.

Key Takeaways
  • A Newcastle study established a "significant" link between pregnancy treatment and childhood asthma risk.
  • Soot air pollution particles were found in the placentas of mothers in London, according to a named study cited on the page.
  • Women with endometriosis face an elevated risk of premature birth and require special care during pregnancy, according to a referenced medical study.
  • A study conducted in Denmark examined the association between contemporary hormonal contraception and ovarian cancer in women of reproductive age using a prospective, nationwide cohort design.
  • PVC flooring in homes was linked to increased uptake of phthalates in pregnant women, according to a pregnancy medical study referenced on the page.
  • Fruit intake was associated with a reduced risk of endometriosis, according to a study highlighted in the endometriosis section.
