In short
- FSH (follicle stimulating hormone) is a hormone that plays an important role in fertility and reproduction in both women and men.
- In women, FSH stimulates the growth and maturation of eggs in the ovaries and plays a role in the menstrual cycle.
- In men, FSH is involved in the production and development of sperm cells.
- A high or low FSH value can be associated with changes in fertility or the function of the ovaries or testicles.
- FSH levels change in women throughout the menstrual cycle and are therefore often measured at a specific time.
- A finger prick blood test can measure FSH levels and provide more insight into your hormone balance.
- During fertility testing, FSH is often assessed together with other hormones, such as LH and estradiol.
- Would you like more insight into your fertility or hormone balance? An FSH test can provide valuable information.
What is follicle stimulating hormone and what role does this hormone play in the body?
Follicle stimulating hormone (FSH) is a hormone produced by the pituitary gland, a small gland in the brain. In women, FSH stimulates the growth of eggs in the ovaries. In men, FSH supports the production of sperm cells in the testicles. FSH therefore plays an important role in reproduction.
What does a high or low follicle stimulating hormone value mean?
A high FSH value may indicate that the ovaries or testicles are not functioning properly. The body tries to compensate by producing more FSH. A low FSH value may indicate that the pituitary gland is not producing enough FSH, which can affect the maturation of eggs or sperm cells. The meaning of the result depends on your sex, age and other hormone levels.
What symptoms can be associated with an abnormal follicle stimulating hormone value?
In women, an abnormal FSH value can lead to irregular periods, absence of menstruation, difficulty becoming pregnant or menopausal symptoms such as hot flushes and night sweats. In men, an abnormal value can cause reduced fertility, lower libido or problems with sperm production.
What effect does follicle stimulating hormone have on the menstrual cycle and fertility?
FSH ensures that an egg matures and is released each month in women. If the FSH value is too high or too low, menstruation may become irregular or stop. This can make it more difficult to become pregnant. In men, FSH is needed for the production of healthy sperm cells and is therefore important for fertility.
What can cause follicle stimulating hormone levels to be elevated or reduced?
FSH can be elevated during menopause, when the ovaries or testicles function less effectively, after chemotherapy or radiation treatment, or due to certain pituitary gland disorders. FSH can be reduced due to problems with the pituitary gland, the use of certain medications, or severe stress or being underweight.
When is it advisable to measure follicle stimulating hormone?
It is advisable to measure FSH if you experience irregular or absent periods, have difficulty becoming pregnant, or if your doctor suspects a problem with your hormone balance. Measuring FSH can also be useful in men with fertility problems.
How is follicle stimulating hormone measured and how do you interpret the result?
FSH is measured using a finger prick blood test. The result is compared with normal values for your age and sex. In women, the point in the menstrual cycle at which the blood was taken is also sometimes considered. Your doctor will assess what your FSH value means together with other test results.
How can an abnormal follicle stimulating hormone value be treated or improved?
Treatment depends on the underlying cause. Sometimes no treatment is needed, for example during menopause. If there is a problem with the pituitary gland or the ovaries/testicles, your doctor may prescribe medication or recommend further investigation. For people with a desire to have children, fertility treatments may sometimes be possible. A healthy lifestyle, sufficient nutrition and reducing stress may also help in some cases. Always discuss with your doctor what is best for your situation.
