One of the most important tests in the field of health heart diagnostics (HHD) is the LH: FSH Ratio test, which measures the ratio of luteinizing hormone (LH) to follicle-stimulating hormone (FSH). The pituitary gland secretes these two hormones, which are essential for controlling the reproductive system and play major roles in controlling reproductive processes. The LH: FSH Ratio is essential for the diagnosis of some disorders in women, such as PCOS, where there is usually a larger ratio because of raised levels of LH in comparison to FSH. Additionally, this ratio offers insightful information when evaluating ovarian reserve and menopausal status. This ratio is useful for assessing gonadal function in men, especially when hypogonadism or infertility are present, as changes in these hormone levels may point to underlying problems.
