Spontaneous pregnancy loss is not uncommon. Approximately 10-15% of pregnancies result in a miscarriage and 5% of women will experience two or more consecutive miscarriages. Causes of miscarriage and recurrent losses vary, but there are assisted reproductive technologies that we can provide you to overcome these challenges.
What are the causes of recurrent pregnancy loss (RPL)?
With a thorough fertility evaluation, we can identify the cause of RPL in 50% of couples. Potential causes are:
Despite extensive research of potential causes of RPL, 50% or more patients will not have an identifiable cause for their pregnancy loss. It may make you feel frustrated, but no identified cause could also suggest a good chance of a successful pregnancy and live birth in the future.
What is my chance of having another pregnancy loss?
The chance of another pregnancy loss will depend on the reason of prior pregnancy losses, number of prior losses and the woman’s age.
For women in which no clear reason could be identified, the overall chance of subsequent pregnancy is likely – even without treatment, a woman has a 60-80% chance of conceiving and carrying a full-term pregnancy.
What fertility treatment options do I have to avoid another pregnancy loss?
Treatment approach will be targeting the underlying cause of recurrent pregnancy losses, including:
In those cases of recurrent pregnancy loss without an identified cause, making a precise treatment plan can be difficult and needs to be individualized. We encourage you to discuss with our doctor and choose the appropriate treatment that would avoid miscarriage as much as possible.
Can Preimplantation Genetic Testing help me?
If you or your partner has known chromosomal structural abnormalities such as balanced translocation, selecting normal embryos via PGT-A will significantly decrease your chance of pregnancy loss.
For couples who do not have identifiable cause, data suggested that PGT-A in women age 38 or beyond will significantly decrease risk of miscarriage after IVF treatment.
Can male factors be the cause of pregnancy loss?
Merging data suggested that compared to men whose partners had not experienced miscarriages, the sperm of those whose partners had recurrent pregnancy loss had higher levels of sperm DNA damage. We offer sperm DNA fragmentation testing for those women in whom no female cause of RPL could be identified.
