Question

LH and FSH level during human menstrual cycle increase on?​

Answer 1

LH and FSH are the hormones that encourage ovulation. Both LH and FSH are secreted by the pituitary gland in the brain. At the beginning of the cycle, LH and FSH levels usually range between about 5-20 mlU/ml. ... This change in the LH to FSH ratio is enough to disrupt ovulation.cells of the anterior pituitary gland, and regulates the development, growth, pubertal maturation, and reproductive processes of the body. FSH and luteinizing hormone (LH) work together in the reproductive system.When a woman is undergoing a fertility work-up, Cycle Day 3 is the day she has blood work performed to check the levels of three important levels: follicle stimulating hormone (FSH), luteinizing hormone (LH) and estradiol (E2). FSH is secreted by the pituitary gland.Higher-than-normal LH levels – when seen with high FSH levels – can be a sign of ovarian failure (which can result in infertility [1]). Another common cause of elevated LH can be a syndrome known as Polycystic Ovarian Syndrome – or PCOS.According to Mayo Medical Laboratories, the reference values (most typical values) for FSH are: Males older than age 18: 1.0-18.0 International Units Per Liter (IU/L) Postmenopausal women: 16.7-113.6 IU/L.Although LH levels will not remain high after pregnancy, it is important to remember that the chemical makeup of HCG is very similar to that of LH. While pregnancy tests can tell the difference between LH and HCG, ovulation tests cannot.
