what does very low fsh mean
A low level of FSH may indicate an imbalance in the pituitary or hypothalamus. A high FSH level may indicate an imbalance with the testes or ovaries ability to function properly. In women, the FSH test (it is a blood test) is taken on the 3rd day of the menstrual period. Doctors believe levels higher than 10-15mIU/L may indicate diminished fertility, poor egg health or low ovarian reserve.
