What causes low hCG levels after IVF?

What causes low hCG levels after IVF?
A previous study found that certain maternal or fetal characteristics, as well as IVF treatment variables, may affect initial hCG levels (6). A low initial hCG level may be associated with maternal obesity, smoking, nulliparity, male fetus, and decreased placental weight.
What is a good first hCG level after IVF?
With detailed statistical analysis (ROC curve) they concluded that an hCG level of 76 mIU/mL was a suitable cut-off point for predicting viable pregnancy with 80% sensitivity and 82% specificity. The positive predictive value for a viable pregnancy at this level was 87% and the negative predictive value was 74%.
Can low beta hCG levels after IVF?
Initially low serum β-hCG levels 14 days after frozen blastocyst transfer indicated minimal chances of live birth. For patients having an initial β-hCG > 58.8 mIU/ml, luteal phase support should continue. Another serum β-hCG test and ultrasound should be performed one week later.
Can you have a successful pregnancy with low hCG levels?
Even if a complication associated with low hCG levels occurs, such as a miscarriage or an ectopic pregnancy, this does not mean that someone will be unable to get pregnant again or that their fertility is compromised. A successful pregnancy is still possible with low hCG levels.
Can low hCG levels mean twins?
That said, hCG levels vary from person to person and pregnancy to pregnancy, so hCG levels are not definitive to determine a twin pregnancy. Some people have high hCG levels and only give birth to one baby; others have exceptionally low hCG levels and give birth to multiples.
Is it OK if hCG doesn’t double?
If your hCG levels aren’t exactly doubling but are still increasing, that’s a good sign. Because of these natural variations, hCG patterns alone cannot determine whether or not your pregnancy is viable. Hormone testing should always be followed up by an ultrasound before a diagnosis is made.
