Patient's question:
NoDoctor's answer:
Hello, Follicle-stimulating hormone (FSH) is an important gonadotropin secreted by the pituitary gland, which can promote the secretion of androgens and estrogens by the gonads and adrenal glands. Measuring serum FSH is of great value in determining the etiology and site of lesions in disorders of sex hormone imbalance. The level of serum FSH varies significantly during different periods of a woman's life; it also exhibits certain fluctuations within a day, usually being higher in the morning than in the afternoon. During puberty, this difference is even greater. For ease of comparison, standardized blood collection times are generally required.
