Instead, in the three obese PCOS phenotypes no differences in serum insulin, Homeostatic Model Assessment of Insulin Resistance (HOMA-IR) calculation, and lipid blood values were observed.Compared with normal LH-FSH, serum TT progressively increased in altered LH-FSH ratio with higher cut-offs. Two studies from India also found similar findings [ 27 , 28 ]. These findings also indicate that LH-FSH ratio just > 1.0 is enough to produce significant testosterone from the ovaries causing hyperandrogenemia.FSH/LH ratio is used for diagnosing polycystic ovarian syndrome (PCOS), menstrual irregularities, fertility problems, delayed or precocious puberty. ... In men, the increased levels of FSH and LH may indicate a condition called primary testicular failure, where the gonads fail to work properly themselves. There are many causes for this ...In group III (LH:FSH ratio below one) only, the FSH levels (7.43 µlU/ml) were very higher than all other groups, and then the AMH levels were the lowest (3.7 ng/ml) in this group. High FSH levels inhibit AMH levels and low FSH levels stimulate AMH levels in this study.

This indicates a healthy balance between the two. However, studies show that an LH to FSH ratio of 2 or 3 — meaning LH levels are higher than FSH levels when measured on the same day ...Structurally, FSH and LH are composed of an alpha and a beta subunits. While alpha subunit is identical between gonadotropins TSH and hCG, the specific beta subunit confers the unique biologic activity. Upon release in circulation, FSH binds to G-protein coupled receptors in the testicular Sertoli cells and ovarian granulosa cells.Results: PCOS patients were observed to have different ranges of LH:FSH ratios from < 1 range to 4.6-5.5 and subjects were classified into 7 PCO subgroups on the basis of their LH:FSH ratios.
