High levels of LH in men can indicate so-called primary testicular failure, which can be due to defects in the development of the testes or to illness (e.g. adult mumps), injury, for example during sport, or due to treatment for cancer in the form of chemotherapy or radiation therapy.
27 Φεβ 2024 · When men experience low levels of FSH and LH, it can have significant implications for fertility and overall well-being. In this article, we will explore the causes of low FSH and LH in men and discuss potential solutions for addressing this hormonal imbalance.
In patients with signs and symptoms indicative of hypogonadism, determining luteinizing hormone (LH) and follicle-stimulating hormone (FSH) levels together with the initial testosterone level is usually most efficient.
23 Νοε 2023 · FSH and LH are key regulators in the male reproductive system. FSH is primarily responsible for stimulating sperm production, while LH triggers the production of testosterone. An imbalance in these hormones can lead to various fertility issues.
1 Μαΐ 2023 · These GnRH pulses lead to an increased LH: FSH ratio. This skewed ratio leads to the theca cells of the ovaries producing excess androgen while the granulosa cells do not produce enough aromatase to convert the androgens to estradiol.
Elevated LH and FSH values indicate primary (testicular) hypogonadism, whereas low or importantly even inappropriately ‘normal’ LH and FSH values may indicate secondary (pituitary–hypothalamic) hypogonadism.
15 Μαρ 2022 · Our findings suggested a strong link between elevated LH and LH/T ratio and atherosclerosis as LH was an independent predictor of impaired endothelial function and morphology (FMD%, CIMT, AS) in all subjects, and LH/T was a predictor of increased CIMT.
