During which of the 4 stages is progesterone at its highest?
the luteal phase
Progesterone is the dominant hormone after ovulation (the luteal phase). Progesterone is produced by the corpus luteum, which is the area on the ovary created by the collapsed follicle that contained the ovulated egg. Progesterone levels peak in the middle of the luteal phase (8,9).
What should progesterone levels be throughout cycle?
0.1 to 0.7 ng/mL in the follicular stage of the menstrual cycle. 2 to 25 ng/mL in the luteal stage of the menstrual cycle. 10 to 44 ng/mL during the first trimester of pregnancy. 19.5 to 82.5 ng/mL during the second trimester of pregnancy.
What week is progesterone highest?
In the Third and Fourth Week Once ovulation takes place, the endocrines in your ovaries will begin producing progesterone. During this time, your progesterone level will gradually rise to 2 ng/ml or more. This will stimulate the walls of the uterine to thicken in anticipation of implantation of the egg.
What is considered low progesterone in early pregnancy?
During the first trimester, maternal progesterone increases slowly, to around 40 ng/ml. Between weeks 6–8, doctors consider low progesterone levels to be less than 10 ng/ml, which is a sign of an abnormal or ectopic pregnancy. In the remaining trimesters, progesterone levels continue to increase to 150 ng/ml.
What was your progesterone at 4 weeks?
(study) According to the American Pregnancy Association, “They (progesterone levels) can range from 9-47 ng/ml in the first trimester, with an average of 12-20ng/ml in the first 5-6 weeks of pregnancy.”

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.
At what progesterone level will you miscarry?
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].
What is the normal range for progesterone levels?
Relationship Between Progesterone Level and Variability of Pregnancy < 5 ng/mL (16 nmol/mL) Low level, non-viable pregnancy < 10 ng/mL (32 nmol/mL) Low level, abnormal pregnancy < 25 ng/mL (80 nmol/mL) Ecquivocal range >25 ng/mL (80 nmol/mL) Normal level, normal intrauterine pregna
When does progesterone peak during pregnancy?
The level will reach its peak in the first 8-11 weeks of pregnancy and then will decline and level off for the remainder of the pregnancy. Fertility and menstruation are largely controlled by hormones, progesterone is an endogenous steroid and progestogen sex hormone in our bodies that stimulates and regulates various functions.
What should your progesterone level be at 3rd trimester?
Third-trimester pregnancy: 48.4 to 42.5 ng/mL. Progesterone levels are usually higher when you are pregnant, but even in a non-pregnant patient, they can reach 20 ng/ml. In a pregnancy cycle, they should be greater than 10 to 12 ng/ml to have a better chance of a good pregnancy outcome.
What is a normal progesterone level for a 14 year old?
Here is the average normal progesterone level that a male should see: 5 to 9 years of age: 0.7 ng/mL. 10 to 13 years of age: 1.2 ng/mL. 14 to 17 years of age: <0.8 ng/mL.
