Can you have PCOS with normal hormone levels?
It is possible for some women with PCOS to have their hormone levels within the “normal” range while suffering from androgen-related symptoms. These key patterns of hormonal changes can often be seen in women with PCOS: Increased androgens (testosterone, DHEAS, and androstenedione)
What levels of hormones indicate PCOS?
FSH and LH are often both in the range of about 4-8 in young fertile women. In women with polycystic ovaries the LH to FSH ratio is often higher – for example 2:1, or even 3:1. With PCOS we often see the FSH in the range of about 4-8 as well – but often the LH levels are 10-20.
What is the normal PCOS level?
Laboratory Investigation of PCOS
| Test | Normal value |
|---|---|
| 40 to 59 years—0.4 to 2.03 pg per mL (1.40 to 7.00 pmol per L) | |
| DHEAS | 600 to 3,400 ng per mL (1.6 to 9.2 μmol per L) |
| Androstenedione | 0.4 to 2.7 ng per mL (1.4 to 9.4 nmol per L) |
| 17 α-hydroxyprogesterone | Follicular phase < 2 μg per L (6.1 nmol per L) |
Does PCOS mean you have low estrogen?
Most women with PCOS are surprised to find that their estrogen levels fall within the normal range (about 25-75 pg/ml). This may be due to the fact that the high levels of insulin and testosterone found in women with PCOS are sometimes converted to estrogen.
What conditions can mimic PCOS?
Other disorders that mimic the clinical features of PCOS should be excluded: thyroid disease, high prolactin levels, and non-classical congenital adrenal hyperplasia. Large ovaries with many small follicles (which look like cysts, hence the name “polycystic”).
What hormones are low in PCOS?
The lack of ovulation alters levels of estrogen, progesterone, FSH, and LH. Progesterone levels are lower than usual, while androgen levels are higher than usual. Extra male hormones disrupt the menstrual cycle, so women with PCOS get fewer periods than usual.
