  2. Fertility testing - Wikipedia

    en.wikipedia.org/wiki/Fertility_testing

    The clomifene citrate challenge test is similar to cycle-day-three FSH testing. To perform this test blood samples are taken on day three of the menstrual cycle to obtain FSH and estradiol levels, then 100 mg of clomiphene citrate are given orally once a day on days 5 through 9 of the menstrual cycle, and finally on day 10 of the menstrual ...

  3. Ovarian reserve - Wikipedia

    en.wikipedia.org/wiki/Ovarian_reserve

    The most commonly used test to assess this ovarian reserve is the day 3 FSH test. [7] This blood test determines the level of FSH on cycle day 3. Cycle day 3 is chosen because at this time the estrogen level is expected to be low, a critical feature, as FSH levels are subject to a negative feedback.

  4. Follicle-stimulating hormone - Wikipedia

    en.wikipedia.org/wiki/Follicle-stimulating_hormone

    Follicle-stimulating hormone (FSH) is a gonadotropin, a glycoprotein polypeptide hormone. [1] FSH is synthesized and secreted by the gonadotropic cells of the anterior pituitary gland [ 2 ] and regulates the development, growth, pubertal maturation , and reproductive processes of the body.

  5. Ovulation - Wikipedia

    en.wikipedia.org/wiki/Ovulation

    Ovulation occurs about midway through the menstrual cycle, after the follicular phase, and is followed by the luteal phase.Note that ovulation is characterized by a sharp spike in levels of luteinizing hormone (LH) and follicle-stimulating hormone (FSH), resulting from the peak of estrogen levels during the follicular phase.

  6. Polycystic ovary syndrome - Wikipedia

    en.wikipedia.org/wiki/Polycystic_ovary_syndrome

    Some other blood tests are suggestive but not diagnostic. The ratio of LH (luteinizing hormone) to FSH (follicle-stimulating hormone), when measured in international units, is elevated in women with PCOS. Common cut-offs to designate abnormally high LH/FSH ratios are 2:1 [102] or 3:1 [95] as tested on day 3 of the

  8. Luteal phase - Wikipedia

    en.wikipedia.org/wiki/Luteal_phase

    The luteal phase is characterized by changes to hormone levels, such as an increase in progesterone and estrogen levels, decrease in gonadotropins such as follicle-stimulating hormone (FSH) and luteinizing hormone (LH), changes to the endometrial lining to promote implantation of the fertilized egg, and development of the corpus luteum. In the ...

    en.wikipedia.org/wiki/Hypergonadotropic_hypogonadism

    Hypergonadotropic hypogonadism (HH), also known as primary or peripheral/gonadal hypogonadism or primary gonadal failure, is a condition which is characterized by hypogonadism which is due to an impaired response of the gonads to the gonadotropins, follicle-stimulating hormone (FSH) and luteinizing hormone (LH), and in turn a lack of sex steroid production.
