Causes and Risk Factors of Chemical Pregnancy
In an assisted pregnancy that uses frozen embryos, damage that occurs to the embryo during the freezing process may result in a chemical pregnancy; as many as 20 percent of pregnancies involving the transfer of frozen embryos result in a chemical pregnancy.
Other causes can include:
- An insufficient (too thin) uterine lining
- A problem with DNA in the sperm
- Low hormone levels
- Pregnancy with an IUD in place
