Is a follicle-stimulating hormone (FSH) level of 8.7 mU/mL normal?
Follicle-stimulating hormone (FSH) at 8.7 mU/mL may or may not be normal depending on the patient's sex. Detailed analysis is as follows:
1. Normal
If the patient is male, the normal range for follicle-stimulating hormone is 0.9–9.8 mU/mL. Within this range, FSH promotes maturation of the seminiferous tubules in the testes and sperm production, indicating normal reproductive function.
2. Abnormal
If the patient is female, the normal FSH range is 1.7–8.5 mU/mL. Normally, FSH promotes follicular development and maturation, working together with luteinizing hormone to facilitate follicular secretion of estrogen and ovulation. An FSH level of 8.7 mU/mL is slightly elevated, which may indicate diminished ovarian reserve. If levels continue to rise, fertility may decline, and premature menopause could occur in severe cases.
Patients with abnormal FSH levels should seek medical guidance for treatment, such as using progestin medications including progesterone capsules, dydrogesterone tablets, or medroxyprogesterone acetate tablets.
