Follicle stimulating hormone or FSH (follitropin) is a hormone that is produced in the pituitary gland and is usually analyzed in connection with an investigation of your fertility. The FSH test analyzes your levels of follitropin and is carried out to give you more insight into your fertility.
For women, FSH tests are recommended to assess the ovarian reserve and identify the cause of possible menstrual disturbances.
For men, it is recommended to identify the reason for low sperm volumes in semen.
