FSH

FSH is one of the essential sex hormones. By its precise measurement at IntroLab laboratory, we can provide important information about your reproductive health and help you understand your hormonal state.

What is FSH?

Follicle-stimulating hormone is one of the hormones secreted from the pituitary gland, located at the base of the brain. FSH plays a key role in regulating the growth and development of ovaries in women and testes in men.

In women, follicle-stimulating hormone promotes the growth and maturation of follicles (small spherical structures) in the ovaries. Each of these follicles contains an egg cell. When a follicle matures, it releases an egg in a process known as ovulation. In men, this hormone stimulates the testes to produce sperm.

Why is the FSH analysis done?

Several reasons why FSH may be determined include:

• Infertility: FSH is often measured in men and women who have fertility issues. High levels of follicle-stimulating hormone can be an indicator of a reduced number of egg cells in women or a reduced number of sperm in men.
• Menstrual problems: If a woman has irregular, missed, or heavy menstrual cycles, measuring this hormone can help identify the issue.
• Early or delayed puberty: In children showing signs of early or delayed puberty, the FSH test can be used to assess whether these changes are occurring within the expected timeframe.
• Menopause: In women showing signs of menopause, testing can help confirm whether a woman is going through menopause.

The values of this hormone are usually interpreted in combination with levels of other hormones, such as estrogen, progesterone, and luteinizing hormone (LH). It is always best to consult with a doctor or reproductive health specialist if you have questions or concerns about FSH or other hormones.

Preparation for the analysis

For women, it is important to consider specific days of the menstrual cycle when taking a blood sample, so it is necessary to consult with a doctor. No additional preparation is needed. Ideally, blood should not be taken immediately after eating.
