Order FSH Blood TestFollicle-stimulating hormone (FSH) is a glycoprotein hormone produced by the anterior pituitary gland. It plays a central role in reproductive function, influencing gonadal development and gamete production. An FSH blood test measures the concentration of this hormone in the bloodstream, offering a direct view of pituitary signaling and, by extension, the functional status of the reproductive axis.
About FSH Blood Test in Normal
The FSH blood panel is a laboratory assay that quantifies follicle-stimulating hormone in serum or plasma.
FSH is secreted by the pituitary in response to gonadotropin-releasing hormone (GnRH) from the hypothalamus. In women, FSH stimulates ovarian follicle growth and estrogen production; in men, it supports spermatogenesis by acting on Sertoli cells. Because FSH operates within a feedback loop involving the gonads, its level can reflect disorders at the pituitary, hypothalamic, or gonadal level.
Clinicians order an FSH test to evaluate conditions such as infertility, menstrual irregularities, premature ovarian insufficiency, and suspected pituitary or hypothalamic dysfunction. In men, it may be used to investigate low sperm count, testicular failure, or delayed puberty. The test is often combined with luteinizing hormone (LH), estradiol, testosterone, and other markers to provide a fuller picture of endocrine function.
Results are interpreted in the context of age, sex, and clinical presentation. Elevated FSH typically indicates reduced gonadal feedback, as seen in primary gonadal failure, while low FSH may point to hypothalamic or pituitary causes. Normal reference ranges vary by laboratory and population, so values should always be assessed alongside the broader clinical picture and other hormone measurements.
