In women FSH stimulates the growth and development of ovarian follicles (unfertilised eggs) during the follicular phase of the menstrual cycle.
A women’s cycle is divided into two phases, the follicular and the luteal, by a mid cycle surge of FSH and luteinising hormone (LH)
FSH levels are useful in the investigation of menstrual irregularities, meaning irregular periods and to aid in the diagnosis of pituitary gland disorders.
In children FSH and LH are also used to diagnose delayed or precocious early puberty and investigate problems with growth.
FSH and LH are normally requested by men or women whom are investigating their own infertility journey; however FSH is also used to see if women have reached the menopause.
In women FSH and LH levels can help tell the difference between primary ovarian failure and secondary ovarian failure.
When us ladies enter the menopause, our ovaries stop working, our FSH levels will rise, this is a normal process. The average age in the UK of onset estimated at 51 years of age, however the normal age range is wide, but rare to be affecting younger women than 40 years old!
