Birth Defects

Because up to 80% of early miscarriage is caused by birth defects, here is a list of traits that put someone at risk for having a baby with birth defects:

  • Low folate status (may cause Down Syndrome and neural tube defects)
  • Low folate status in the father (may cause Down Syndrome and aneuploidy)
  • Obesity (causes neural tube defects)
  • High homocysteine levels (causes numerous birth defects)
  • Low vitamin B12 (causes neural tube defects)
  • High soy diet (causes hypospadias)
  • High level of pesticides in the diet (causes hypospadias)
  • High saturated fat diet (causes memory and learning disabilities)
  • Use of Clomid (may cause neural tube defects and severe hypospadias)
  • Severe acne (associated with having a child with autism)
  • Having had breast and uterine cancers, tumors, or growths (associated with having a child with autism)
  • Having a family history of ovarian and uterine cancers, tumors, or growths (associated with having a child with autism)
  • Being over 40 years old (causes aneuploidy and Down Syndrome)
  • Elevated FSH (more important than age in causing Down Syndrome and aneuploidy)
  • Elevated estradiol (causes Down Syndrome and aneuploidy)
  • Taking oral contraceptive around the time of conception (causes Down Syndrome in young mothers)
  • Having a long follicular phase (causes birth defects)
  • Having a long menstrual cycle (causes birth defects)
  • Having had a late menarche (associated with birth defects)
  • Having irregular menstrual cycles (causes birth defects)
