LH (Luteinizing Hormone)
Luteinizing Hormone (LH) is a key hormone involved in regulating the menstrual cycle and ovulation in females and stimulating testosterone production in males. The **LH test** measures the level of LH in the blood to assess reproductive health. It is commonly performed by drawing a blood sample from a vein, which is then analyzed in a laboratory. This test is used to evaluate conditions related to infertility, ovulation disorders, polycystic ovary syndrome (PCOS), and irregular menstrual cycles in women, as well as to assess pituitary function and male infertility. It is typically administered during specific phases of the menstrual cycle in women (e.g., around ovulation) or when a doctor suspects issues with hormone balance or reproductive health. Additionally, it may be used in the diagnosis of conditions affecting the pituitary or reproductive organs in both men and women.
