The six sex hormones include follicle stimulating hormone, luteinizing hormone, prolactin, estradiol, progesterone, and testosterone, the details of which are as follows: 1. follicle stimulating hormone, also known as follicle stimulating hormone, decreases mostly during estrogen and progesterone treatment, and increases mostly in premature ovarian failure, ovarian insensitivity syndrome, and primary amenorrhea. 2. luteinizing hormone, which is too low, mostly indicates inadequate gonadotropin function. If luteinizing hormone or follicle stimulating hormone is ≥3mIU/mL, it is one of the bases for the diagnosis of polycystic ovary syndrome. 3. prolactin, too high can be diagnosed as hyperprolactinemia. 4. estradiol, decreased is mostly seen in ovarian hypofunction, Silhan’s syndrome, premature ovarian failure, etc. 5. progesterone, low progesterone value in late ovulation is mostly seen in luteal insufficiency, ovulatory dysfunctional uterine bleeding. 6, Testosterone, increased testosterone value can trigger infertility, most of the increased testosterone is mostly seen in polycystic ovary syndrome.
