What is a normal FSH and LH level?
The reference range for FSH in adult males is 2 – 12 IU/L and for LH is 2 – 9 IU/L….Reference range.
| Phase | FSH (IU/L) | LH (IU/L) |
|---|---|---|
| Early follicular | 3 – 10 | 2 – 8 |
| Mid-cycle peak | 4 – 25 | 10 – 75 |
| Post-menopausal | > 20 | > 15 |
| Pregnancy | < 1 | 2 – 9 |
What does FSH LH mean in a blood test?
What is it used for? An LH test works closely with another hormone called follicle-stimulating hormone (FSH) to control sexual functions. So an FSH test is often done along with an LH test. These tests are used in different ways, depending on whether you are a woman, man, or child.
What FSH level indicates perimenopause?
FSH is sometimes used as a measure of whether a woman is peri or postmenopausal. An FSH level of > 30 IU/L is consistent with the perimenopause, although FSH levels of 70-90 IU/L are not uncommon for postmenopausal women.
What if LH is higher than FSH?
Higher-than-normal LH levels – when seen with high FSH levels – can be a sign of ovarian failure (which can result in infertility. Another possible cause of an elevated LH concentration can be a syndrome known as polycystic ovarian syndrome – or PCOS.
What is a high LH level?
The main takeaway: There is a wide range of what’s considered “normal” for urinary LH. One large study showed that the median LH on the day before ovulation was about 44.6 mIU/mL, but that LH could be as high as 101, or as low as 6.5.
Why LH is high in PCOS?
Women with PCOS have an increase in both the LH pulse frequency and amplitude, resulting in increased 24-hour secretion. This increase in LH secretion is thought to occur as a result of increased frequency of hypothalamic gonadotropin-releasing hormone (GnRH) pulses.
