Luteinizing Hormone (LH) is produced in the anterior pituitary gland and plays a significant role in keeping your reproductive system healthy and functioning. LH is often measured when evaluating ovulation in women; when levels appear to be high it can sometimes indicate infertility .
High LH levels are commonly seen in women who have :
- Polycystic ovary syndrome
- Early menopause

Risk factors of high LH levels
In women, LH stimulates the ovaries to produce oestradiol - the major female sex hormone primarily responsible for maintaining and maturing the reproductive system. If a woman's LH levels rise above average, and the woman isn’t currently in menopause, it’s sometimes a result of the following conditions.
Polycystic ovary syndrome
Polycystic ovary syndrome (PCOS) is a common condition that can affect women of reproductive age. It’s common for women with PCOS to also experience high LH levels .
Though the underlying cause isn’t actually known, there are some indicators associated with PCOS, these include:
- Irregular periods
- Excess body hair
- Difficulty getting pregnant
- Weight gain
- Thinning hair or hair loss
Early menopause occurs when a woman’s periods stop before the age of 45. This can happen naturally if a woman’s ovaries stop producing normal levels of certain hormones - this can have an effect on LH levels .
The symptoms of early menopause are similar to typical menopause symptoms, these include:
- Hot flashes
- Night sweats
- Vaginal dryness and discomfort during sex
- Difficulty sleeping
- Low mood or anxiety
