Your LH is within the expected range, suggesting appropriate pituitary signalling to your reproductive organs.
Very low LH means the pituitary has essentially stopped signalling the gonads (testes or ovaries). This may contribute to hypogonadotropic hypogonadism — the gonads shut down sex hormone and sperm/egg production because they receive no instruction. Causes include hypothalamic amenorrhea, pituitary tumors, very large malnutrition, and anabolic steroid suppression.
Seek urgent endocrinology evaluation. MRI of the pituitary and hypothalamus may be needed. Stopping anabolic steroids and weight restoration (in low weight states) are priorities.
LH: {{value}} {{unit}} — very low (ref: {{low}}–{{high}})Low LH reduces testosterone production in men and disrupts ovulation in women. Causes include stress, very large exercise, very low body weight, prolactinoma, and anabolic steroid use. Low LH alongside low testosterone distinguishes secondary hypogonadism (pituitary problem) from primary hypogonadism (gonad problem).
See your doctor for comprehensive pituitary and hypothalamic evaluation. Treating the underlying cause (stress, weight restoration, stopping steroids) often restores LH.
LH: {{value}} {{unit}} — below reference range (ref: {{low}}–{{high}})Borderline low LH can reflect mild stress, suboptimal sleep, or early hypothalamic-pituitary axis suppression. Symptoms may be subtle.
Optimize sleep, reduce stress, and check testosterone and sex hormones for context. Discuss with your doctor if symptomatic.
LH: {{value}} {{unit}} — borderline lowYour LH is within the expected range, suggesting appropriate pituitary signalling to your reproductive organs.
No action needed. Evaluate alongside FSH and sex hormones for complete picture.
LH: {{value}} {{unit}} — within reference rangeYour LH is right in the healthy range, providing appropriate stimulation for sex hormone production and reproductive function.
No action needed.
LH: {{value}} {{unit}} — optimalBorderline high LH can be a normal LH surge before ovulation in women, or can indicate the pituitary is working harder to stimulate gonads that are starting to underperform.
Evaluate in context of cycle phase for women. Evaluate with testosterone for men.
LH: {{value}} {{unit}} — borderline highHigh LH indicates the pituitary is signalling more intensely because the gonads are underresponsive. In men, high LH alongside low testosterone indicates primary hypogonadism (testicular failure). In women, elevated LH is a marker of perimenopause/menopause or PCOS.
Evaluate alongside testosterone, estradiol, and FSH. The specific cause and treatment depend on whether this is primary gonad failure, menopause, or PCOS.
LH: {{value}} {{unit}} — above reference range (ref: {{low}}–{{high}})Very high LH suggests primary gonadal failure (the gonads have largely stopped functioning), postmenopause, or rarely an LH-secreting pituitary tumor.
Seek endocrinology evaluation. Comprehensive reproductive hormone panel and pituitary imaging may be needed.
