About the hormone FSH

Follicle stimulating hormone (FSH) is a hormone produced in the pituitary gland which causes the follicles in the ovary to grow. FSH can be used as an indicator of the ovarian capacity to produce eggs. If the ovaries are "dull", the pituitary gland increases the FSH level. Therefore a high FSH level is evidence of impaired function of the ovaries and reduced ovarian reserve.

FSH changes during the woman's menstrual cycle. Therefore, it is important that the blood sample is taken at the right time (day 2-3 of menstruation). By measuring FSH and estradiol early in the cycle, one can measure the individual maximum value of FSH and estrogen control value that FSH were taken at the right time. FSH values ​​can only be interpreted if there is a simultaneous measurement of estradiol levels. 

On average, FSH is low in younger (less than 8 IU / L) (International Units per Liter) and increases with age to the highest values ​​around menopause (above 25 IU / L). The lower the FSH value, the more likely it is that the ovaries will produce egg cells of good quality.

Trianglen treats women with FSH values ​​up to 15.  Women with a higher FSH value only have a very little chance of getting pregnant and giving birth to a normal child, as a result of fertility treatment.
