Is it possible to have a viable pregnancy with low progesterone?
Assuming a woman is not taking progesterone supplements, in pregnancy a progesterone less than 5 ng/ml is nearly always abnormal. Conversely, a progesterone >23 ng/ml is almost always viable and in the uterus (not ectopic, or tubal).
How high does progesterone have to be to sustain a pregnancy?
The results show 25 ng/ml is an effective threshold serum progesterone level for sustaining pregnancy in the first trimester in women with a history of miscarriage or infertility in both women of prime fertility age (22-34 years) and advanced maternal age (35-45 years).
Does low progesterone predict miscarriage?
Many studies have shown that low serum progesterone is associated with threatened miscarriage. Our group has validated a single serum progesterone cutoff of 35 nmol/L taken at presentation with a threatened miscarriage can differentiate women at high or low risk of subsequent miscarriage [14, 15].
Why is my progesterone dropping in early pregnancy?
Low progesterone causes Low progesterone during early pregnancy is often the result of one of the following: An ectopic pregnancy. A miscarriage. A threatened miscarriage (when there is vaginal bleeding, spotting and/or cramping in the first trimester)
At what hCG level is pregnancy viable?
At an hCG level of more than 3000 mIU per milliliter, 0.5% of pregancies will be viable , 66.3% nonviable, and 33.2% ectopic [2]. Nonetheless, a live singleton birth can still result even with hCG levels above 4000 mIU/mL and no ultrasound findings on initial examination.
What should progesterone level be at 5 weeks?
Progesterone levels also can have quite a variance at this stage of pregnancy. They can range from 9-47ng/ml in the first trimester, with an average of 12-20ng/ml in the first 5-6 weeks of pregnancy. With both hCG levels and progesterone levels, it is not the single value that can predict a healthy pregnancy outcome.
Can low progesterone cause miscarriage at 12 weeks?
Now with all that being said, a lack of progesterone is NOT the reason why you miscarried. The placenta takes over progesterone production at the 6th week so a luteal phase defect or lack of progesterone would not cause a miscarriage at that point.
What is a normal progesterone level for 6 weeks pregnant?
Progesterone levels also can have quite a variance at this stage of pregnancy. They can range from 9-47ng/ml in the first trimester, with an average of 12-20ng/ml in the first 5-6 weeks of pregnancy.
Can a pregnancy be viable with slow rising hCG?
There were 22 pregnancies with slow rising beta-hCG levels (13.9%) and 16 (72.7%) of them showed viability at 8 weeks but not after the first trimester. A sac-crown rump length discrepancy with the sac smaller than normal was found in 11 of 16 (68.7%) women.
What determines a viable pregnancy?
A “viable pregnancy” after 22-24 weeks is a pregnancy when there is a chance that if delivered the baby can survive. In some countries or circumstances babies have little chance of survival if they deliver before 26-28 weeks mostly because there is inadequate neonatal care.
