Cosa indica l FSH?
Questo esame misura i livelli di ormone follicolo stimolante (FSH) nel sangue. L’FSH è associato alla riproduzione e allo sviluppo degli ovuli nelle donne e degli spermatozoi negli uomini. L’FSH è prodotto dall’ipofisi, un piccolo organo localizzato alla base del cervello.
Come deve essere FSH?
Cercando di generalizzare i risultati, l’esame nelle donne nel terzo giorno di ciclo può essere così valutato: Valori superiori a 15: scarse probabilità di successo (ma non nulle). Valori tra 10 e 15: possibile diminuzione della fertilità dovuta all’età. Valori inferiori a 10: situazione ottimale.
What is the relationship between LH FSH and testosterone?
LH, FSH and Testosterone. LH stimulates testosterone production from the testicles. Testosterone in turn regulates LH secretion by a process called ‘negative feedback’. LH secretion is therefore under restraint from testosterone. Similarly, FSH stimulates sperm production in the testicles, as well as, stimulating production
What happens to FSH levels when testicles are damaged?
The latter is responsible for restraining FSH production from the pituitary, by negative feedback’. When the testicles are severely damaged, both testosterone and inhibin B production are reduced, removing the restraint of these hormones on the hypothalamus and pituitary, leading to high levels of LH and FSH.
What is a follicle-stimulating hormone (FSH) test?
This test measures the level of follicle-stimulating hormone (FSH) in your blood. FSH is made by your pituitary gland, a small gland located underneath the brain. FSH plays an important role in sexual development and functioning. In women, FSH helps control the menstrual cycle and stimulates the growth of eggs in the ovaries.
What does it mean when your FSH and luteinizing hormone are high?
In children, high FSH levels, along with high levels of luteinizing hormone, may mean puberty is about to start or has already started. If this is happening before age 9 in a girl or before age 10 in a boy (precocious puberty), it may be a sign of: A disorder of the central nervous system
